The plants were the right variety. I have never had any mis-labelled plants from Costco.
I can't walk past without buying anything - I bought a bag of camassia, a bag of alliums, and a bag of eremurus this past fall/winter. The camassia and alliums are all up - about 3-4 inches tall. The eremurus has not broken ground yet. This is my second year trying to grow that - nothing came up the first time.
