I am in the PNW zone 8 greater Seattle area. I have a bunch of sprouts that I do not know what they are or if I should pull them. Pictures 1-3 are in very shaded area of my garden. The last picture is in a full sun location. I noticed all the sprouts in the beginning of April and have been trying to wait to determine if I can figure out what they are to know if I should let them grow or pull them fast!
I can take more pictures if these do not do justice. I have not seen these sprouts before.
#4 seems to be Aesculus hippocastanum, not Castanea.
#3 The plant between the two ferns looks like Ranunculus, maybe R. aconitifolius or maybe Astrantia sp.
But Looks very similar like a Geranium, too.
