Those are turning out interesting.
Sorry for the foggy pictures, humid greenhouses do that, but here are some pics of the more impressive plants from the seedlings I have:
S. purpurea venosa burkii "Chipola" x typical: this one survivor has gotten large, fast, and very colorful
S. 'Royal Ruby' x 'Adrian Slack: 2 seedligns shown, one is getting very thick, wide mouth and open up very pale pinkish, but age out to form deep red veins, and the other seems to have the ruby pitcher with the Slack lid, and bright areoles
S. x catesbaei "Monster" x purpurea 'Red Ruffles': the biggest of the seedlings has a very wide, ruffled lid, and the color is bright yellow with deep red, contrasting veins, which coalesce on the upper pitcher under the lip to form a nearly solid red zone
I also have 'Leah Wilkerson' x 'Royal Ruby', but so far they haven't really colored up yet. The few that have are showing either LW throat colors, or very reddened bodies.
