Ookkaaayyyy! Rethink the depth thing. Sheesh. I have a rim of Shooting Star around the bottom of the slope that I didn't want to move, and some Anemone Sylvestris in the middle with fringed bleeding heart at one end. I guess I could dig them up and pot them while I redo the dirt. Ugh. Seems like I am constantly doing a major rebuild on beds.
I have about 30#'s of preen to spread early in spring, maybe even on top of the last of the snow. The chickweed is terrible and I just cannot keep ahead of it. I even spread grass clippings (not very deep) to try to inhibit it. Ha! It just came up through.
I will take a look at the inventory of rock garden plants I have from ABG and then remember who did well. Gentiana is really healthy here - or some form of that plant - beautiful vibrant blue flowers. And of course creeping phlox. Bear in mind that the bed is in full sun always but our sun is quite a bit cooler than yours. We don't pay much attention to "plant in shade" instructions here. Hosta, ligularia and such thrive in our sun.
Thanks for the input on the germination of the poppies. I do hope they don't take three months. I cannot have the seeds/soil in the house as it is too warm (69F) and while the garage would be good, no light. If I light up one of my rolling shelves would 55F be okay to germinate. I could turn up the heat from the stack robber a few degrees to make it around 60F if it would help.
