Gardeners' Notes:

Positive Heeve On Dec 8, 2013, Heeve from Sebring, FL (Zone 9b) wrote:

Somniferum refers to the desirable opiate alkaloids (Such as Morphine and Codeine) not Hashish...which is a residue obtained from Marijuana plants. In fact the Latin botanical name means "Sleep Inducing Poppy". Contrary to popular belief, Somni's are opium poppies regardless of cultivar.

Having said all of that, Danish Flags are in my opinion, the most beautiful of them all with the sharp contrasting two-toned flowers and highly recommended for any flower garden even though they can be difficult to grow to maturity in some areas and can take more than normal attention to be successful.

Self sowing once they are successful though and once they've done so take much less care. Definitely give them a shot!

We have a number of papaver species but not the one described. Somniferum always refers to sleep inducing elements in the plant, as in hashish poppy. What about the var, described is it narcotics producing one

I have several versions of this poppy and each year spread seeds. Have done so in fall and spring. Not sure which is best, but I will defer to the Delta gardener as it sounds like they have been at it longer. Mine bloom all summer with many many flowers per plant. Clear up to freeze-up.

Here in Alaska, this plant does beautifully. I've sown it in the spring before the snow melts. I prepare beds in the fall and sow just before break-up, allowing the plants to get an early start. They bloom around mid July and are stunning - though they are effectively a one-time wonder (little repeat blooming). The seed pods stand out in the winter. They will self-seed readily as well. Seeds are easily collected.

This is a lovely very satisfying poppy. It is called danish flag or danebrog because the colors resemble (with red and white cross) the danish flag. Grow as you would other somniferums. Very prolific and fun.
