I am so happy with my one hoya rubra. It's a variegated plant that has been happy living on the corner of the porch getting a bit of morning sun. At the beginning of the summer, it was looking sick and tired and being attacked by aphids (grrrrrr--I picked them all off with my fingers and squashed them). I took it out of the pot, repotted a size up (I know they prefer tight quarters...but there wasn't any dirt left in there....) in compost rich organic mix, and hoped. The plant has bloomed twice, doubled in size, and is setting new umbrels to bloom a third time. And all I do is water it every couple of weeks and try to keep it from climbing the bricks or into my flower bed (it's in a heavy porcelain pot on a plant stand about two feet high). I guess when they like where they are, they really are carefree. I'm happy because this plant is a good childhood memory to me...very nostalgic.
