Gardeners' Notes:

Positive Howard_C On Sep 21, 2004, Howard_C from St John's, NL wrote:

I have grown the Autumn Snowflake here in St John's Newfoundland since 1979. It isn't quite hardy outside in Canadian zone 5b, but has survived for four years in the rock garden until zapped by unfavorable conditions - probably too low temperatures without enough snow cover. (Not surprising in view of its Mediterranean origins.) However, it increases wonderfully well in a pot in an unheated frame against the house on the south side that catches the winter sun. It's just about the earliest of the autumn flowering bulbs to appear here: the first delicate white blooms appear in late August or early September and it goes on flowering throughout September. The grass-like leaves appear soon after flowering and finally die down the following July. I repot every 4-5 years.
