I have a hoya that I have been keeping on our back porch where it is well shaded under large trees. I have read many places where it gives minimum temperatures for hoyas but I would like to know how much heat they can take.
Maximum Temperature
That varies tremendously, depending on the species and where it's from.
If you have seen lists of the minimum temperatures, you have also seen max. temps that person has experienced. Now, there is a difference between the climate conditions with regards to temps. 100 degrees and humid is alot different than 100 degrees and dry. If you really look into the plant and where it comes from, you can look up the range of temperatures from that country and where the plant was found growing. Easy.
True that,
If you are mimicing temps of 100 and high humidity its a lot different from dry heat
Thanks for the responses. Sorry that I'm late to respond. I don't know what kind it is. Here is a photo. For the past week or so our highs have been around 100 f. (38 c.) But the plant is in the shade. As for the humidity I'm not sure what it is. But I am pretty sure it's way lower than yours in Florida.
Your plant is a variegated H. carnosa. They can take heat and cold...they prefer cooler than most but they are hardy and strong hoyas. If you forget to water that's OK too as they like to grow dry. I certainly wouldn't worry.
They also are very happy in airconditioned offices.
Weeds. Hoyas are weeds except in Wisconson and places like that!
LOL Carol
Very nice plant Siggy! I have H. carnosa 'Tricolor': http://davesgarden.com/guides/pf/go/57703/ I'm not sure if it's the same exact plant as yours but takes the same conditions. As AlohaHoya stated, it can take heat and cold and that particular one likes to be kept on the dry side. Most of my plants stay outside year round but we don't get as cold here as you do in zone 8a. I have a little variegated Hoya inside in the guest bedroom and other much larger ones outside on the deck. In both locations they seem to do well as long as they aren't in direct sun which will burn the foliage. It sounds like you have the perfect location for your lovely plant!
Once again knowledgeable DGers help me again! Thanks :-) Looking at the picture of the tricolor I'm pretty sure that's what I have.
My photo doesn't show it but sometimes I get those redish leaves. I bought this plant about three years ago at which time it was blooming. It hasn't bloomed since. Any suggestions on what I might do to get it to bloom?
Patience ^_^ ... sometimes LOTS of patience, which I have none of, LOL.
I am fairly new to Hoya's and sometimes think they have minds of their own when it comes to growing and blooming. I have a small Hoya kerrii that has had a peduncle (bloom spur) for over a year and it finally has buds! I've noticed a difference in my plants blooming more since I began feeding them once in awhile. I have always been real bad about feeding my plants ... never seemed to remember to do it and I'm trying to be more consistent. Whatever plant food I use, I always dilute it even more than it says on the package.
If your Hoya has bloomed in the past, do you see any little bloom spurs on the plant anywhere? One thing that I learned from someone on this forum awhile back ... be careful if you trim or prune Hoya's, don't remove the little bloom spurs after they are done blooming because they re-bloom from the same spurs. Now, that said ... I have also had the little spurs just fall off at times!
