PHILODENDRON HASTATUM var. GLAUCOPHYLLUM (silver )

What a X'mas gift !!! just loved it.

This was my birthday present. I was so happy, I did not mind being a year older.

this one too

Wow, Armando ... Merry Christmas! I don't think I have the same Santa Claus that you do! I've never had Santa bring me a XMAS present that nice!

and ... Placenciarita: Happy Birthday! That is one nice variegated split leaf ... I love plants with variegated foliage! Nice Birthday gift!

Gosh, I need to think twice when making my Christmas and Birthday "wish" lists!

PLANTLADYLIN,
Lin, I behave all year around, DID YOU ???? LOL
Just kidding.
Armando

LOL Armando! Yep, I've always been one to behave myself year round. I guess I need to talk to Santa and tell him that I really, really would love a green living plant for my X'mas gift!

I adore your little drawing! Did you do that? That would make a great card for plant lovers!

Lin

plantladylin,
Lin, yes I did it myself, I am a retired painter and designer
Armando.

Armando: Your talent shows!

Merry Christmas!

I too am a little jealous of your birthday present! I've always wanted a white vareigated Monstera!

I have been trying to get a yellow variegated monstera, but whenever I would find one, they usually cost more than I can afford. I'm still looking. Here is a picture of texasbigleaf monstera.

This Wal-Mart markdown makes me happy whenever I look at her. I enjoy giving them a second chance.

placenciarita- That's a pretty one- great save!

I have a really old one that I've had for over 15 years and it was about that old when I got it. I've noticed that it has kind of stopped growing. I think I may need to try some cuttings since it's so old :(

I really love the one with the white in the leaves! Someday I hope to find that one. Wow! That Monstera in the hanging basket is great! I had no idea one would grow that large in a basket that size! Is that a 10" basket?

I have one large Monstera and a couple of young ones that don't have the splits in the leaves yet. This is my largest:

Great Monstera Lin!- and Carludovica too!!! What is the little hanging basket?

Diane: I know it's a Columnea or Lipstick Plant but I can't tell in the photo which one. I took that photo above last spring and I move stuff around constantly! It could be Columnea 'Carnival':
http://davesgarden.com/guides/pf/go/166203/

Or possibly Lipstick Plant 'Rasta': http://davesgarden.com/guides/pf/go/162725/

Love the Columneas and Lipsticks. Pretty yellow blooms on that one! Rasta is actually one that I'm always on the look-out for! Always scoping out the EAs for that one...


Edited 'cause I can't type and spell properly!

Dianejungle, I have a old monstera too. Right now it has only 2 leaves on it, but I haven't the heart to cut it down. I might need the room If I ever get a yellow variegated one

plantladylyn, the pot is 10", I would like to know about the palm in the picture. it's very unusual. I would love to have one. Do you know the name of it?

Placenciarita: The plant to the right of the Monstera is called the Panama Hat Plant. Not a palm but very palm like in appearance. Here's the link to this plant in Plant Files: Carludovica http://davesgarden.com/guides/pf/go/72394/

placenciarita- Yea, I know what you mean. I realized this summer I would probably need to take cutting on mine this summer- couldn't make myself do it. Figure I'll give it one more year to see if it decides to take off again!

Placenciarita's new yellow variegated monstera. Merry Christmas.

A close-up view.

TXbigleaves- Nice Secret Santa job! That's so sweet!

Thank you Santa Jerry, That truly is sweet, guess that I will have to take out my old plain green monstera to make room for this beauty, thank you again. Merry Christmas.

Giancarlo's photo at the top of this thread does not appear to show the true Philodendron hastatum. The plant in the photo appears to be either a form of Philodendron subhastatum or possibly something else. Without better detail photos it is difficult to be certain but there is no blue/green color in the leaves.

Philodendron subhastatum originates in Colombia and Ecuador while Philodendron hastatum is found only in a small region north of Rio de Janeiro where the very rare species Philodendron spiritus-sancti originated. Philodendron subhastatum was at one time a synonym of Philodendron hastatum but has been divided out. The real Philodendron has blue green leaves when young and becomes an enormous plant as it ages.


PHILODENDRON HASTATUM var. GLAUCOPHYLLUM


There is a scientifically known plant as Philodendron hastatum K. Koch & Sellow. The name “Philodendron glaucophyllum” is a made up name that first appeared in AB Graf’s book Tropica and there has never been a scientific name Philodendron glaucophyllum or a variation of Philodendron hastatum known as “glaucophyllum”. This belief is nothing more than a horticultural myth. Check any of the scientific plant databases and you cannot find the name "glacophyllum".

Many people now believe the name Philodendron hastatum has been changed to Philodendron domesticum. I spent months chasing this in 2006 and Dr. Tom Croat of the Missouri Botanical Garden finally solved the riddle.
I once posted an explanation on Dave’s Garden but there was not a single response:

In a personal email from Dr. Croat received March 3, 2007, Tom wrote, ""I have never seen the type of P. domesticum and doubt if I would know any more if I had seen it. Just looking at the illustration I could imagine that it could be a dozen different species. The reason why it is confused with P. hastatum K. Koch is that the plant he described had commonly been called P. hastatum. Naturally it had nothing to do with P. hastatum. It was just another cultivated plant of unknown origin. He accomplished nothing by describing it and instead just created another plant likely never to be understood. The paper by Sakuragui listed below just deals with the real P. hastatum and has nothing to do with the plant that Bunting described."

Most people do not read past Dr. George Bunting’s opening line that appears to say he has changed the name of Philodendron hastatum to Philodendron domesticum. That never happened as Dr. Bunting clearly explains in the text.

Had the reader finished reading Bunting's entire paper they would have found this quote by the good doctor himself, "The spade-leaf philodendron is a popular foliage plant with glossy bright green leaf blades to about 6 dm. long borne on equally long petioles. Its spathes are pale green outside but beautifully colored inside with cherry-red on the blade and wine-red on the tube. This taxon is commonly designated as Philodendron hastatum. Such usage, however, is untenable, for the name properly belongs to a very different species. Philodendron hastatum C. Koch & Sellow was first published in 1854"

George Bunting clearly states in his paper he was not attempting to change the name of the scientifically known species Philodendron hastatum (1854) to Philodendron domesticum. Today, the name Philodendron domesticum is not considered a valid scientific name since the plant is a hybrid.

I will not bore you with more details because I am well aware some find my explanations boring. You can read it here should you choose: http://davesgarden.com/community/forums/t/1085476/

Clearly, if you prefer to call any plant by another name that is your choice. I have been asking Dave’s Garden to change the info on Plant Files for some years and finally have the attention of a knowledgeable individual that can hopefully clarify all of this for the thousands of people that read Plant Files every year.

Again, I mean no disrespect to the great aroid grower Giancarlo. This has been a commonly believed misconception for years. My only goal is to have the facts known to growers.


If you are interested in the entire story of how this myth began you’ll find it here: http://www.exoticrainforest.com/Philodendron%20hastatum%20pc.html

If you are of the opinion this information is totally bogus please make a request on the International Aroid Society FACEBOOK account for a clarification from one of our botanists. I’m certain the moderators will ask one to respond to you directly.

Appears I may be unsuccessful at changing any minds on Plant Files. At least I would like anyone looking up the name Philodendron hastatum or Philodendron domesticum on Dave's Garden to see photos and drawings of the real plants.

The juvnenile form of Philodendron hastatum K Koch & Sellow by aroid botansit Dr. David Scherberich:

A midsize plant of Philodendron hastatum K Koch & Sellow

A drawing provided by Dr. Simon Mayo of the Royal Botanic Garden Kew in London of the adult form of Philodendron hastatum K Koch & Sellow Please note there are clearly no fenestrations (holes) in the leaf in this drawing.

A photo supplied by the Marie Selby Botanical Garden in Sarasota, FL of the adult or near adult form of Philodendron domesticum Hort.

This is not a species but instead a hybrid created during the 1960's. Dr. George Bunting wrote a paper on the plant naming it Philodendron domesticum Hort. (a horticultural name, not a species name) but stated in his paper he was not changing the name from Philodendron hastatum K Koch & Sellow.

They are two very different plants. For some reason in the 1960's growers liked to call this plant "Philodendron hastatum" but it never took the place of the actual species.

Additionally, there is a plant name of Plant Files called Philodendron hastatum (Engl.)

It is my belief, but I could be wrong, that plant is the same plant that began this file as Philodendron hastatum glaucophyllum. The name "glaucophyllum" cannot be found in science in relationship to any Philodendron.

According the Royal Botanic Garden Kew World Checklist of Selected Plant Families the name Philodendron hastatum Engl. is a synonym of Philodendron subhastatum. P. subhastatum is also a totally different plant found in Colombia and Ecuador.

If you are fortunate enough to own the blue-green Philodendron hastatum K Koch & Sellow, take good care of it. That plant is somewhat common in collections but is now a red-lined species in Brazil and is now considered rare.

None of the three plants are closely related.

The photo attached is courtesy of Dr. Tom Croat and the Missouri Botanical Garden

Just in case you are curious (and I realize I am the "curious" one here), it is common for the name Philodendron hastatum K Koch and Sallow to be published as Philodendron K Koch and Sello. I have no idea why but you can find it both ways in many scientific documents.

Forgive me, items I indended to include.

Some seem to believe the USDA/GRIN indicates the name Philodendron hastatum was changed to Philodendron domesticum At one time they did have such a page on their site and apparently it still exists but these are the current pages according to a botanist at GRIN.

Read carefully what it says about one plant not being the other.

The two plants are clearly not one and the same.

wow original post from 2007 are you bored or what?

My edit is only to include this thread as a reference.

http://davesgarden.com/community/forums/t/1104387/


Ms. Roper, this type of combative response on a plant discussion forum serves zero purpose. It does not serve to stimulate discussion or to educate anyone. It appears to serve no purpose other than to assure no individual with an education in plants ever disagrees with you.

I am certain you believe that when you respond to my posts in this manner I become fearful of you. I do not. I am certain that when you display disdain for anyone that has taken the time to educate himself or herself in the field of plant science, you make us quiver with fear when you “bark”. We do not. There are others on this forum with great knowledge of aroids and a few of us love to carry on honest and open discussion. You are welcome to join.

I received no less than seven personal emails from folks on this forum apologizing to me for your recent outburst on another thread. Every one of them encouraged me to continue to post good info and I intend to do just that. One even told the story of a previous encounter when you attacked an individual and apparently that person promptly stood up to you finally causing you to express regret for what you had written. I expect nothing. Some of us, probably many of us, find your attitude toward those of us that want to share information as well as your choice of words disdainful.

You are an excellent grower. I congratulate you for the quality of the plants you grow. I have received e-mails from people that claim to know you that include photos of your collection. You grow some awesome plants.

At one time you began a very nice website explaining how you grow them. I read every single page on your site which has apparently since vanished from the Internet. You should have continued, however by doing more careful research the integrity of your site would have been greatly enhanced. Websites don’t grow on their own, they must be actively promoted.

You obviously have knowledge of your plants, but you have more than once posted plant photos with bad names and information on other forums. You are free to call any plant in your collection by any name you choose. You are free to grow any plant in your collection in any way you choose.

However when you begin to share inaccurate names and information with novices that are inclined to trust your judgment I must take exception and respond.

The Internet is filled with bad information on aroids. There is likely more bad information on how to grow aroid plants as well as plant identification than there is qualified information. Bad information persists due to people who continue to copy and publish bad photos and bad information.



My concern is not you or your choices of plant names, my concern is all the people that listen to you. You once posted photos on another forum of a plant you identified as Anthurium cubense. Your plant in that photo is not the species.

Any individual who has taken the time to train themselves in the science of that species knows how to count the primary veins, knows how to analyze the petioles (the stalks that support the leaves), knows how to look for the pubescence (hair) at the base of the stem (central axis of the plant), and knows how to look at the structure as well as the angle of the primary veins as they emerge from the mid-rib and depart to the edge of the blade (margin).

These are the reasons some of us enjoy reading the scientific description of a plant. By checking the science against the plant we can come to a better conclusion as to the correct name of the species we want to understand. When you insist you are correct and your information is clearly contrary to science you do nothing but attempt to assert your domination over the conversation.

This combative behavior on your part has gone on against me since late 2005. I fully understand your goal both here and on other forums. You want me to become angry and leave. Thus, your assertion I leave forums when my “feelings get hurt” would be validated. I will not. In fact, it is you that has tried and tried to force me off forums!

You want me to strike back at you so you can do your best to turn my response into a good reason why people should pay no attention to my posts. As I once stated on the UBC forum, I refuse to fall for the bait you are casting. You will never receive an angry response from me, but you will also never receive another apology when I attempt to be civil! I have tried consistently to be nice to you but you only respond with disdain.

This battle you attempting to rage began on GardenWeb where you use a different handle. Several times once I made posts attempting to answer a question you would respond with "I thought we got rid of you". You did not. I still to this day post on GardenWeb, primarily on the aroid forum. Interestingly, I haven't seen you there for a long time but I am certain I will soon see your return and the combative nature of your responses will once again increase. Be prepared, I will gladly copy and paste this post there as well!

You posted bad information regarding Anthurium regale and I contacted your stated source. He disagreed with you because I have also communicated with him for years. Further, while seeking good information to share with the public, I contacted Dr. Thomas B. Croat at the Missouri Botanical Garden. Dr. Croat immediately disagreed with you.

Oh, please forgive me; I just realize I am "throwing around" another name.

During the year 2008 there was a huge confusion on the Internet regarding a plant that many people were selling as “Anthurium jenmanii” for up to $1000 for a single plant. The plant truly being sold was Anthurium bonplandii subspecies guayanum.

On the UBC forum you called me to task saying there was no way I could identify a plant based on that reddish new leaf that was being produced by the plants for sale. The posts are still on UBC and can easily be found. I never said I could identify the species although I have now studied both plants in detail. I did not attempted to identify anything, I quoted a complete e-mail from Dr. Croat and HE SAID the plant being sold could not be Anthurium jenmanii. You try to argue with me, when in fact you were arguing with the world's best-known aroid botanist. Do you truly believe you are more highly qualified than the most highly educated and published aroid botanist in the field of aroids on the face of this planet

And by the way, since you implied on this forum I leave forums once I feel attacked. You should be aware I have made well over 1000 posts on UBC since the moderators began to either edit or completely delete your spiteful posts. Again, you likely didn’t know it but each one of them were botanists!

I would never say you are not welcome here, you certainly are and have every right to post whatever you believe. At the same time, those that know your information to be incorrect have a right and an obligation to others that may read it to explain to others that have less knowledge the information is wrong.

. I would never tell you that you are not entitled to your personal beliefs or opinions, but I will quickly say your attitude is not welcome if all you wish to do is be combative in an attempt to belittle others. Personally, I will not be fearful and I will not bow down to your "authority". Please feel free to post, but please bite your tongue if you believe threats are going to make any of us kneel before you in fear. We will not. Intimidation does not work in this setting.

Best wishes and please continue to post, however, please consider what you are saying and check your facts before you post them.

And by the way, as a result of what I am about to say, I've also seen your unkind posts regarding the IAS and botanical gardens that charge a fair admission in order to stay in business. Should you ever choose to join the IAS, it will be my pleasure to personally welcome you as a member with a similar letter to the one I send to every new member.

You would be most welcome to attend the International Aroid Society show in Miami this September. It would be my pleasure to introduce you personally to some of the top aroid botanists on the planet and I am certain some would consider corresponding with you if you wish to verify information. Tom will be there as will botanist Pete Boyce from Malaysia. There will be some great discussion groups and classes going on including more horticultural discussions than have ever been had at one of our shows in the past. I have personally invited both LariAnn and Scott Wade from this forum to give talks aimed at growers. Both have accepted. And since you have indicated elsewhere Fairchild charges too high an admission price I will personally arrange to get you into the garden for free along with a guest of your choice. All I need is a weeks notice in advance of the event. To top it off, I will do all possible to see that we do not meet if that is your choice.


Best wishes, and please continue to post.
