plants arrived early

this week i recieved 3 shipments from spring hill nursery.  it was stuff they owed me from last year, sort of.  the blue clips died. so i got new ones.  something from the drought tolerant perrenial grab bag died, so they sent me an entire new grab bag!  the cool thing is. only one plant is a repeat, the moonbeam coreopsis, which i love!  they also sent me golden and dragon's blood sedum, salvia, red hens and chicks, and this plant i've never heard of called little plum.  apparently there are no plums involved.  anyway, i want to put the golden sedum under the japanese maple, but i'm wondering if the lily of the valley are going to come up.  while almost all of my spring bulbs have begun to at least peek a shoot above the ground, they are still hiding.  maybe i will put the golden sedum there anyway, between the lily of the valley.  now to figure out where to put the coreopsis and blue clips...
