After a, no joke, 7 year ongoing effort to get a california poppy to flower in Los Alamos, NM. I win. The key for this one is that it was a seed that did NOT flower from a planting last year. I have tried planting in the late fall before unsuccessfully. But maybe this was close enough to the house to winter without getting too cold? Not sure. A woman down the block has them growing like weeds in her yard, she actually has to weed them out of other beds, why is she so blessed? Probably as she is right with the god. I am so not right with god, in my defense though, it said nothing about that on the back of the seed packet. I will further investigate as seasons progress. She also graciously will allow me to collect seeds from her known producers. We tried transplanting her unloved poppies to my yard, but california poppies resist transplanting and seem to even resist starting them indoors in compostable pots and then just plain old planting the whole pot in the ground.
So the new plan is to monitor the poppies planted this year to see if any succeed, and then to sow seeds in october or november this year.
