This is my first post to the list and I hope I get it right! Jane, I can offer a little advice (more of a warning) based on my mistakes. My first experience with Leontice sown in normal 10cm deep pots resulted in good germination but no tubers. After experimenting again with deep pots I came to the conclusion that the seedlings seek considerable depth before starting tuber formation and if the stem that grows downward to form the tuber encounters 'air pruning' at a drainage hole before they reach a depth they like then no tuber is formed. Even with 20cm deep pots standing on sand I found tubers formed partially extended from the drainage holes and I had to cut the pot to release them. My advice at this stage is that if you sowed the seed in a shorter pot you should stand it partially plunged in a bigger pot of sand or similar. Then look in the bigger pot for your tubers once top growth dies back. Darren Sleep Lancaster UK
