Quick question on Hoya tolerance of air temps

I am going to pick up a few plants for myself and based on what is in the quote below, would like to know which plants are best suited to being grown in hanging baskets in a home where the air temps are generally maintained at around 70F all year round save some nights when we leave the windows open and the temps drop down to around 60F and some days during the summer when we open up the house and the temps rise to around 78F.

I guess what I am asking is should I be selecting C, I, or W hoyas?

Quoting:
TEMPERATURE TOLERANCE
Temperature tolerance is the ability of a plant to withstand the extremes of temperature, both lower and upper. While most species can tolerate an upper temperature in excess of 27 degrees C, some can not. The converse is the lower temperature tolerance, which varies considerably from species to species. Consequently two temperature requirements should be taken into account.

We have inserted the letters C, I, or W to represent what we consider the plants temperature tolerance.

C = COOL We assign this to plants that can tolerate a continual exposure to a lower temperature of 10 deg. C . Also included here are those plants that are intolerant of temperatures above 25 deg. C.

I = INTERMEDIATE Plants that can tolerate a continual exposure to a lower temperature above 10 deg. C. Some species in this group are intolerant of temperatures above 35 deg. C.

W = WARM These are usually lowland tropical species and are intolerant of a continual exposure below 15 deg. C. This group will grow quite happily in temperatures above 35 deg. C.


I have all of 7 hoyas at home right now. All are growing happily at room temperatures year round. I'd like a few more that are capable of being tossed in a hanging basket and left alone for all practical purposes and would be able to narrow down my search if I could determine whether I should be purchasing C, I, or W hoyas. It's looking as if Intermediates are the way for me to go.

I would go with the Intermediates.... Most of them will hold up with drops lower than specified. My greenhouse drops down to the upper 50's in the winter...but not ALL night and they are undercover.

Thank you, that works for me.

What would be the second choice from there? C or W?

Keaau, HI(Zone 11)

I would go with whatever you feel you can handle. W if you feel you can keep a constant temp and C if that is easier for you.


You are supposed to SAVE me from circuitry overload and just go easy on me by picking a second choice for me so I don't have to tax my neural cells by thinking ;) Shame on you for giving me options when I'm somewhat brain dead right about now! I've got the old calculator out and this is what I've come up with-

10C roughly equals 50F
15C roughly equals 59F
25C roughly equals 77F
35C roughly equals 95F

My house never has temps lower than 60 and rarely below 65F and that's only when we open up the windows in spring and fall. I can tell you for sure we never hit household temps of anywhere near 95F so I guess I'll go for W as second choices!

I first, then W as an alternate. How's this sound! I think I've got this down pat now! I have got to go take a shower. I've been outside most of the day and the ticks are really bad this year. You are lucky, you don't have ticks in HI.

All kidding aside, I do thank you for your explanation.

Keaau, HI(Zone 11)

I WISH!!! Yes, we DO have ticks...not up where I live (for some reason I have only found 1 on the dogs in 6 years) but more closer to the coast.

You could probably get by growing some of the cooler growing hoyas if you have a cool place...

The W hoyas, however, go really squirrelly if they get blasts of cold air, like doors opening in the winter or sumpin like dat!!! They do like lots of circulation, but no blasts.

Confused? Join the group!

I've been sitting here pulling one tick after the next off of me while I've been typing. They're brutal this year for some reason. We've been using flea combs on the dogs to get them off and our dogs aren't even outside dogs... they only go outside to pee and poop.

I don't have a cool place for them and I don't grow Heliamphora so there's no fancy refrigeration for roots around here. My basement would be about the coolest and that's only temporary because I start a lot of plants down there right around the first of the year and I've got metal halides as well as other lighting down there. Those lights can heat up the basement in no time flat. Fortunately, we do have a mud room type deal so cold blasts of air from kids running in and out don't get far in this house. We have a front door but rarely use it. I's and W's it is for me!

No, I'm not confused per se because I know my limit and I'm already over it with information. It's going to be sink or swim for which ever hoyas I buy. I'll do my best to stick with the I's but after that, it's survival of the fittest for them around here.

I put my plants, including the hoyas, outside mid spring, when the nights are still as low as the mid-40's, and they all seem fine. (all types) I do not recommend this though, and if there is an untimely frost, you better be prepared to be out there to drag them all back indoors.

Been there done that with Sarracenia. About 500 pots to be exact and it happened again this spring. Go figure considering it's 91F outside today and it's only the middle of May. I think I am going to leave my Hoya inside. Less to worry about and I don't have that many of them. I like the way they look inside my home and I'm sort of attached to the ones I have. They add a nice touch that isn't silk here. I've never done well with inside plants for some reason yet with hoyas, they seem to thrive on neglect. So far they've been a perfect house plant for me.

Last year I put carnosa and pubicalyx and obovata out too early, I know they are not hard hoyas to replace but the first two were also my first and oldest hoyas, about 16 or 18 yrs old. They didn't die but I lost almost half of the foliage, and neither plant has recovered back to it's previous constantly blooming self. And the pubicalyx had so generously given me seed pods the summer before, I still get guilty pangs when I look at them. Obovata was just a big rooted cutting, more of which I had inside, and even that didn't die. Really, I'd rather keep all my plants inside all year but they get more light outdoors, fresh air and good old rainwater.

Really sorry about your hoyas. I think I would have cried. It wasn't until just recently that I've been able to keep indoor plants alive. I would have been devastated if I had trashed plants I'd had for two decades.

Its not too bad. They are still hanging in there. Maybe this summer they will show some more new growth. Problem is that I had to cut them back so severely that I lost peduncles that had bloomed more times than I could count, some of them were probably 2 inches long, maybe longer!

Eesh, that sounds even worse. I think I will definitely leave mine inside. They are the only non-fru fru plants I have in the house. I really have grown attached to mine and they are pretty bomb proof for the most part.

Equilibrium -

You are wise to grow 4 wheel drive hoyas!!! Life is too short for many of us to fiddlefaddle about with hyperhoyas. I tried my darnest with H. linearis and a couple of others...now I just don't grow them. Makes me a good grower not having to throw them out!!!! Some folks grow them beautifully...

I refuse to have disfunctional relationships with people or plants!!!!

Pretty funny! That about sums up roses for me and why I will not grow them.

I have no problems with linearis with the exception of a little bit dying back in the winter months. I don't water it more than any other hoyas either, I wait for the day that it is dry and then water lightly because of it's shallow root system. So far so good! But for now, with no greenhouse and lack of good light in my house, I stay away from the fussy hoyas too.

LOL, I like the disunctional comment :) I have been selling, giving, trading off hoya's that require to much attention too. I don't have the time or the patience. Plus the one's that I have grown out that really don't float my boat. I gained alot of room. A few more plants out the door and I should be able to take a small vacation this year :) It's just amazing how these plants have taken over my life, I can't even be out of town for more than three days....

Braggart! Just about everyone and their brother tells me that's a hard one and that was one I wanted to try but I was too chicken.

I hear ya TamiF on giving away plants. I just ditched a boatload of orchids because I wanted more space for less demanding plants. I am going on vacation for two weeks next month and I'd like to come back to happy plants not dead plants.

I also now keep linearis year round in an "atrium", a little room that is actually the foyer of my house, with no heat or AC and 2 big skylights. I have never had a plant kept in this room do badly, it is almost as good as a greenhouse. Unfortunately, I can't fit ALL my plants in there. The plant is maybe a year and a half old, I have had it about a year - I am hoping for flowers this year!
