Hoya lasiantha seems to be a very popular hoya, evident on the feedback left at SRQHoyas.com. I certainly know why since the species is very easy to grow as long as it is watered regularly and not allowed to dry out. I have also noticed that the leaves tend to turn yellow if I neglect feeding it for a few months. When I notice this, I drench with a bit of Epsom Salts Rain Water, for the next few waterings.
The blooms, once described as fuzzy chicks, appear on very newly established plants. This young Hoya lasiantha (below) shows three stages of blooms. Sometimes, just following a growth spurt, one vine will display many peduncles getting ready to burst open and bloom at various times. It seems to me that as soon as the stem is strong enough to support the weight of the flowers, the nodes will begin to push out the flowers. I have never detected a scent from these orange, strangely unique flowers, but that’s ok with me!!!
