Thank you for the advice, Roberta! I envy your growing conditions - even being in the warmer part of the UK is nothing like California, unfortunately! I'm quite limited for space indoors, but as you say they stay nice and small.
I'll keep in mind what you suggested about the water as well.
Well I'm quite excited to see how it will do. Judging from the dried up spike it came with it has already flowered this year, but should I get it to flower for me next year I'll post some pictures!
