Poppies - light requirements

Posted by vajeff 7b VA (My Page) on

This year I'm trying paeoniflorum, somniferum, rupifragum, hybridum, nudicale, and Eschscholzia californica poppies. I'm a bit conflicted on the light requiremnts. From what I've gathered, somniferum and nudicale enjoy darkness. My germination spreadsheet says that rhoeas and laciniatum do too, however I'm not growing those. I've read that rupifragum prefers light. As for the rest, I have no idea. There seems to be conflicting directions for paeoniflorum... to surface sow or to cover, light or darkness. I'd try both methods but I do not have enough seeds to experiment with and would like to avoid unnecessarily wasting any.

Here's a list of the poppies I'm about to sow:
"Danish Flag"
Breadseed (well, I wintersowed these but I plan for more)
"Fruit Crush"
"Tangerine Gem"
"Thelma Crawford"
NOID black paeoniflorum
Iceland
"Thai Silk"

Any help would be great!

I don't see anything on your list that requires darkness to germinate. I'd surface sow all, or very lightly cover...placing just a bit of the sowing medium or some grit on top to insure good soil contact.

I've sown somniferum and nudicale plenty of times direct sowing anywhere from earliest winter to earliest spring (Z 8b)- direct sowing: literally tossing the seeds into beds where I would like to see the plants grow. I haven't attempted to cover seeds at all.

The p. rupifragum might benefit from a brief moist chill of 2 weeks or so (40ish F) - does not always need it but you might experience more complete germination with a moist chill.

Thank you. I'm not sure why my list has darkness down for some... Will have to fix that.

Do you have any troubles with birds eating the seeds? Every time I try to direct sow, the seeds go missing in a few days. It makes things a bit complicated when trying to start plants that resent transplanting.
