Freeze and thaw, freeze and thaw. I'm thinking about what to do with all those plants arriving in April and May. With very wet clay in the back - wetland, really - I'm aiming for a wet prairie, and I'm using what I can learn from Perennials and their Garden Habitats by Hansen and Stahl (I finally found a used copy discarded by the Iowa City Public Library), and the little Noel Kingsbury has written on the subject. My plant list (partial):
Panicum virgatum 'Rotstrahlbusch' - 30
Spartina pectinata 'Aureomarginata' - 6
Molinia caerulea 'Strahlenquelle' - 25
Molinia litoralis 'Transparent' - 6
Eupatorium purpureum 'Coelestinum' - 10
Calamagrostis brachytricha - 15
Sesleria autumnalis - 12
Carex muskingumensis - 12
Darmera peltata - 15
Euphorbia palustris - 4
Matteucia pennsylvanica - 12
Kniphofia caulescens - 9
Eupatorium fistulosum, other panicums, a start of a hedgerow of Magnolia grandiflora, viburnums, ilex verticillata and other plants are already in the ground. I can't wait to see what thrives, what just survives, and what is dead.
This is an experimental garden and I'm looking for every source of information I can lay my hands on. If I could read German, I'd be talking to the folks at Hermannshof (see the link below for an automatic translation into English).
