David I too enjoyed the tussell. I am planning on use of your choices this next summer because I am building a 6000 sq ft woodland that has many Hamemelis, Cornus, and parrotia that would love the covering of clematis. Do you know of any that are definatly off the list to climb trees? I am also building a lot of rotted stump pieces in the woodland that will need rather aggressive clematis to cover in the summer. Some of these will be 15' high by 30' diameter. Would a larger amount of clay say 20% with 30% sandy loam, and 50% compost be a good growing media for the clematis. Right now there is only shallow dry (in summer) humus and clay as a base. I am building this winter a sawdust/manure layer over to start the addition of the above ammendments near the stump archetecture.
