Obtained originally directly from John Brittnacher, whether this is truly sessilifolia or not could probably be debated but it fits the general description. Plants rarely get much more than an inch across, with squat, very rounded leaves that will flush orange with crimson tentacles when either fed less or under direct sun (heavier feeding results in greener plants), and with short wiry stalks that bear tiny self-pollinating pink flowers. Easy to grow so long as they're fed well and kept warm.
Packets contain approx. 50+ seeds each.
