Hi Dave,
I too order from Rob's a lot...
but another sources is eBay, and I would recommend Neil's Streps by Dennis Miller.
All of his are "Buy It Now" and he has a good selection. Prices are good and the plants are healthy.

Be careful! Streps are addictive! I got back into them last March and I have over 70 varieties now!
