Finally decided how to do the "garden formerly known as vegetable" into a really cool tropicalesque bed. Got Musa sikkimensis banana coming, found a Canna stuttgart (HOORAY!), ordered a dwarf elephant ear with silver foliage, a thunbergia grandiflora, some annual hibiscus seeds, and some other tropical stuff. Just bought a VARIEGATED red twig dogwood to go in the middle so I have something colorful to look at in the winter. And a dwarf forsythia for early spring color. Will fill in with tropicals I already have - hibiscus, upright elephant ears, cannas, allamanda, I'm sure there are others lurking in the house somewhere!!
As for new pond plants, just a new tropical lily or two - no more room. And I really want a nondwarf papyrus or umbrella palm - it will probably go in a pot sunk in the tropical bed cuz the ponds are FULL!
