I received my original 'rubra' in a small 4" pot from elderly friends in 1976. I didn't know it was a Hoya, only a plant called "Wax Plant" because of the waxy looking flowers. The plant grew rapidly, to the point where I had two very large containers with trellises for the vines to climb. I lost one of the large plants last winter but the remaining one still grows strong and currently has a few buds. The plant originally had the variegated foliage but over the years has reverted back to the solid green color.

I live in East Central Florida, where it's hot in the summertime and humid year round. My plant stays outside on a screened deck, and in the winter when we have cold nights I move the container up against the side of the house and throw a blanket over it for warmth. I grow this plant in a fast draining, chunky potting medium (consisting of lots of orchid bark mix with a little potting soil incorporated). I grow the plant fairly dry, watering every couple of weeks.

I recently bought a small 6" hanging pot with 3 starts at a local plant sale. I've had the green leafed one with creamy flowers for about 15 years, so just had to have this colorful one with burgundy stems and leaf edges that makes a pink flower. Hoyas do very well hanging under my porch where they get filtered morning sun only and water I give them when needed. It's 6-11-18 and my green one has been sending out new growth for a month, so I'll have flowers this summer. They are so pretty hanging over the edge of the oversized hanging basket it grows in. About once a year in fall I give it a haircut to keep it in bounds, and I use the cuttings to root new plants to share or trade.
