This indeed will be the final day with Hoya sp. UT-033; I will be taking a couple of cuttings from this wonderful plant, but I may never see blooms from this one again, because if it takes another five years to flower, I’m unsure that I will still be with the hobby at that point. Perhaps it can be flowered sooner if one used rainwater, or RO water right from the start. That is what I will shoot for.
This is a plant that gets my highest recommendation for even if one can’t flower it, the foliage more than makes up for those shortcomings.
