I am in the middle of clearing ground for a new garden, which, of course, won't be planted until cooler, mid-end Sept weather. I live on the plataeu by Enumclaw, and my soil seems to be pretty good, probably from a combination of old horse pasture and glacial plane. The thing is, in certain spots the soil changes to a really fine textured, almost silky stuff. I think this is described as silt, but am not sure about this. It does seem to hold moisture and drain well. Full sun. I was thinking about planting yarrow (Paprika) and Sea Holly, mainly because that is what I have (plenty, in pots). Are there better perennial flowery type plants that will work? I tend to like the bigger things, 3 to 5 feet. I can amend with compost and chopped leaves if necessary, but this seems like the type of soil that you can amend until the cows come home and barely change the composition. Thanks for any suggestions, ps I am a looooong time reader, but I don't post much. :)
