Thanks, Lauw. I have some seedlings which were germinated during UK spring, and are growing during our spring/summer, so I guess there's a possibility that they will continue this cycle. I wonder whether the process you mentioned works well with Amaryllids which retain their roots during dormancy? I remember reading mails which discussed strategies for getting winter-growing southern hemisphere plants to grow in the northern hemisphere's winter, but what happens if you don't do this? I would be really interested to know if anyone has had any success with such plants, particularly people who experience really cold, wet (non-Mediterranean) winters.
