Initiation of root growth in Fritillaria affinis

I agree, in my opinion winter growing bulbs from Mediterranean or
continental climates root when Summer heat is mitigated by cooler nights,
(and moisture - often in the form of heavy dew).
When temperatures drop below 4 degrees Celsius they actually slow down
root and top growth,( thus, I believe, allowing flower buds more time to
develop inside bulbs).

As I have said before, I am under the impression that refrigerators are
over used for domestic horticulture in some parts of the world.

Frost has arrived here, any winter growing bulbs I now plant will be kept
on my coolest frost free window sill where they can root and pretend it is
still 'Fall'. They will be put outside, in appropriate frames, in early
spring, when well rooted.
