I had a hoya carnosa which died in an unexpected frost in the SF bay area several years ago. I now have a hoya obovata.

I have read that once the flower stalks fall off, it's hard to grow them back. Sadly, my hoya got mealy bugs and all but two of the flowering stems fell off before I got the problem solved. Is it really true that these stems will never grow back? I love hoyas and the hummingbirds and bees love them, too. I hope I can get some advice on how to get my poor plant to grow some new flowering stems.

Thanx!

I am not a super experienced Hoya grower, and all the Hoyas I grow live outdoors in pretty much unprotected pots (though not in full sun) in zone 9b. So far, only a few have survived reliably year after year and this is one of them. It currently, at the time of this writing, has a rating of zone 11 only which is clearly wrong. this plant has not even looked sad when temps dropped into the high 20s. And this is easily the most prolific flowerer of any Hoya I have grown- I always feel lucky when one of my Hoyas bloom, like its some amazing event.. but this thing blooms continuously from late spring into fall.
