Hi South... Your Hoya is probably a carnosa. Sounds like you've got a green thumb at least, since it's been happily growing along and you've managed to share it with many. (A nice tribute to your friend, too.) As for the fact that your daughter's flowers and yours doesn't, that can probably be attributed to the difference between Florida, where the heat and humidty are paradise for Hoyas, and your more northern, less ideal conditions. But have patience - sounds like you're doing everything right. If I were you, I would go get some bloom booster fertilizer. Rapid Grow, I believe, is more of a foliage encouraging fertilizer. Bloom boosters will push the plant to bloom. Also, a lot of us use Eleanor's VF-11. It's not so much a fertilizer and a mineral supplement and works beautifully as a foliar feed. I've linked a source for you below. I tried it first from this supplier and loved it so much, I now order it a case (4 gallons) at a time from Eleanor directly! (I have a LOT of plants...) My Hoyas love the stuff and bloom pretty faithfully, way up here in zone 5-ish.

Keep up the faith!

Thank's so much Denise. Maybe I should put it outside for the summer, but hate the thought of exposing it to more insects. Also thank's for the link to that fertilizer.
