Germinating Alaskan Poppy seeds

(Question)

I am trying to germinate Alaskan Poppy seeds. It has been about a month. They are on a window sill. I’m watering them and nothing is happening.

I have grown them before but started them about a month earlier this year.

Since you have successfully grown the plant from seed before, the main difference between this year and other years seems to be that you have started the process about a month earlier. This earlier date could mean that light levels and temperature on the window sill may be lower than what you would get a month later. These factors could inhibit seed germination. It may just be a matter of waiting longer.

However, here is more general information about getting Alaskan Poppy  (Papaver radicatum subsp.alaskanum) seeds to germinate, some of which you may already know:

Sow Alaskan poppy seeds in moist, seed starter mix. Do not let the seeds dry out.  To keep seeds moist and warm, use a seed tray with a lid or place pots in a plastic bag. Keep them out of direct sun to avoid over-heating. Most seeds need 18-21 degrees Celsius to germinate.

Cover the seeds lightly so that they are no deeper than about the depth of the seed size. Too deep and it won’t get the light it needs to germinate.  To improve the chances of germinating, you may need to add an additional light source.

Alaskan Poppy is native to Alaska and similar northern regions. Many native Alaskan plants require 4 to 6 months of cold as they would outdoors in nature, before germinating. If your seed is not germinating it may be that the seeds need to go through a cold period. If your seedlings have not come up within 4 to 8 weeks of planting, put the seed tray in the fridge for about 4 weeks to give them a cold period. Even after you have removed the tray, it still may take several months for the seedlings to appear.
