I am sure by now you are maybe already concluding that i am so deep into hoyas! And you are correct. I go home to the province more in a month than i am used to, just because i need to tend to my hoyas. I entrusted them to my sister, who hates them at first, but when they started to flower she is also now watering them with love and caring. My posted photos previous to these are all hoyas too!
The only thing not favorable for me is the hoyas inability to bloom when i am at home. It is very difficult to see them opening during weekends, so most of the time i can only photograph the still closed flower buds, like the one below. But even at this stage it is already alluring, don't you agree?
Hoyas need to have pot-bound roots for more flowers to come out. Sometimes i use recycled plastic bottles as their containers. Are you familiar with the bottle above? I am sure you do because the 1.5 L coke bottles are the best suited for them. The bottle's bottom half is inserted below to collect the leachates from the media during watering. That way a higher humidity is given to them for better growth.
The above umbel is not intentionally placed at that position, it serendipitously flowered there. This hoya knows how to get attention! And this species got my sister hooked.
