Edible poppy seeds ARE from the opium poppy, papaver somniferum. They have also been grown for the flowers for centuries and I am sure they are handed down as viable seeds in many places. I have also heard that they have naturalized in some parts of the Pacific Northwest. That said: It is also true that the poppy seeds sold to the baking and grocery industries have been treated by heat or irradiated to prevent them from sprouting. Additionally, if you are required to take drug test for your job, you will want to be careful eating poppy seed cakes, bagels, etc. They can cause you to test positive for opiates!

Thanks! That was quick! Sounds great, I've got them planted at the edge of a butterfly garden interspersed with firebush. I hate not knowing what a plant is!

Your dwarf gray sugar snow peas will have purple blossoms...that's the easy one for me to tell early on. The others you list should all be white flowered. The pods on the Sugar Pod 2 Snow Peas will be flat for quite awhile and the seeds will show though as small bumps. Pick them before the seeds grow large and the pods become rounder since the pods will be tough by then. The Burpeeana Early Peas will have pods that do not stay flat for long and do not show small seeds through the pod. Of course you want to leave this growing until the pods fill with good sized peas. I'd have trouble telling the Sugar Daddy Snaps from the Burpeeana's but since both are picked with rounded pods you can try them and see which has the fibrous pod.....BINGO...that's the Burpeeana and the other should be the tender snap pea, Sugar Daddy. In my garden, heights have not always agreed with the reported info. And some keep growing aller for a longer time and the height when flowering begins changes alot.

Yep, not a native wildflower, it is native to Eurasia. But it has naturalized pretty much everywhere in the temperate world :-) As tom mentioned it is seldom considered a 'true' invasive as it does not really crowd out native plant growth but it does self seed with abandon and many consider it more of a weed than a valuable garden plant. But it IS sold for that purpose :-) Lunaria annua (money plant, honesty) and Centranthus ruber (Jupiter's beard or red valeran) are very similar in this regard - often planted intentionally but just as frequently seen popping up along roadsides or in untended spaces.
