I have great luck with sarcos for a few years but then I lose them, too. Right now I have one called Sarco. Melody 'Southern' in bloom.

I got it at Brennan's. I had a beautiful red that bloomed last year. The leaves have almost all come off but there are some new roots happily growing. I have had a great show on my Den. kingianums and crosses this year. Many I had never seen before!
