Galtonia candicans - I grew it some years ago, it survived for maybe 3 years before disappearing under the onslaught of neighboring chrysanthemums and annuals. It was ok though not over-inspiring.
So far, in the Brent and Becky catalog I've marked Cosmos atrosanguineus, the Chocolate Cosmos (once grown in a pot, then, when planted in the ground, it expired, it's a Z 7), Lucifer, Crocosmia (old ones gave up the ghost), Dahlia 'Happy Single Party', Tuberose (old ones went kind of blah), Ornithogalum 'Namib Gold', kind of new cultivar, and maybe a couple of Lilies (Garden Stone and Whistler).
I have to be careful as I've not much space left to exploit.
