Gardeners' Notes:

Positive vossner On Mar 3, 2012, vossner from Richmond, TX (Zone 9a) wrote:

Some sources say hoya kentiana is often confused w/ hoya wayettii. Foliage looks alike in both plants but h. kentiana is solid green, whereas h. wayetii has a dark red picotee border. Other sources say kentiana and wayetii are the same.

My plant now displays the dark red picotte so I must conclude h. kentiana and h. wayetii are one and the same.

I have one growing in a little black bird cage and hung it in a Live Oak tree this summer. When I went to get it to bring in for the winter I found it was growing up the tree branch and to get it out I'd need a ladder and rip it out. Thought it would be a good experiment. So far I've had 3 freezes and this particular area gets the north wind. I just took a look at it and it appears to be doing well. I'll update in the spring.
Had a freak freeze to 21*. It doesn't look like it made it. Looks kinda mushy.
It's dead, won't do that again.
