I believe what EA is calling Rubra, is a H. Krimson Princess (rubra for the red stems); I've also seen this called H. Picta.

I recently saw a lot of these at my local Home Depot in NYC, they all look like H. KP (inner leaf variegation) w/ red stems.

Hi.. I am a new hoya "mom"... though I've apparently had a carnosa for years and didn't know it until it bloomed a few weeks ago and now I'm hooked..expecting Lacunosa Snow Caps from SRQ/Joni... actually tomorrow!.. but yesterday HAD to go to HD and see what they had.. so being a novice, I'll describe & maybe someone can give me an idea... bought an 8.0 hanging basket (EA) variegated very succulent leaves, many young leaves still white; others getting some green and others have some white and deep pink.. some stems are dark pink.. there is a tiny tip on the end of each leaf and I'd say they are mostly ovate in shape & the older leaves are dark green with some white on edges & are 4" by 2"!. ..cleaned her up and gave a good shower actually a very pretty plant and looking from above (though she's hanging right now) very lush and healthy!.. she'll be moving to my downsized home with me & other plants (and the pug & senior cat) in 2 weeks... hope my lighting is similar!. THANK YOU in advance for assistance here! E
