Title: Hibernating Lilium/Fritillaria seeds
Post by: JPB on November 07, 2010, 07:37:19 AM

I've sown in pots seeds of:

Frittillaria atropurpurea
F. recurva
Iris bracteata
Lilium candidum
Lilium washingtonianum
Paradisea liliastrum

Can I leave them outside to get some frost (minimum -10 to -15C) in winter? Or should I keep them in the frostfree greenhouse ( > 3C)?

Thanks, HAns

We'd put all of these  outside after sowing, Hans and take them under cold glass protection when they germinate.

Of course we have lots of frost in Scotland - if you read Ian's Bulb Logs over the years you will see that here in Aberdeen, only two miles from the sea, we have had to minus 19 degrees C for a couple of weeks on some occasions and that often we have to minus 10 or 12.

Hans, here is a weather report, made by my friend John Lupton on his weather observations for 2009... he lives about seven miles away from me ......

We have already had some nights to minus 3 degrees this autumn.

Lord knows I'm no expert but just in case you didn't know Hans Lilium washingtonianum is one of the Lilium species with dealyed hypogeal germination so don't chuck it out too early if it appears not to be doing anything.

Yes, I know that, thanks David. I have grown L. martagon from seed succesfully.
