If you have buckets or large pots without large drain holes you can put them in the bucket, cover with dryish sawdust, peat, bark or potting soil and store out of the sun for quite awhile that way. Pick a mouse-free place.
I could use Queen Kong & Sunwolf if you have any to spare, will pay postage or I can trade some American hybrid seedlings, L. pumilum, L. lankongensi, L. strictum, Awesome seedlings or Lavender Frost seedlings (what I have to move or have in pots.) or some hosta starts if you are looking for something to fill in that shady area.
