I had the first 3 pods crack today from S. Appalachain Spring and S. rubra jonesii. The Appalachain Spring pod is an attempeted cross with S. oreophila; the 2 rubra jonesii pods are an attempted cross with Appalachain Spring (backcross). However, mesh got wiped out by weather while they may have been still fertile, so just call them open pollinated, haha.
Still to go are more S. rubra jonesii, Judith Hindle, flava, S. rehderi, and alata x minor, all open pollinated.
