Check out our Tioga Party

On of our obsessive plant friends, Glen Melcher, of Tioga, Lousiaiana, sent us several seedlings a few years ago, from his cross of Hibiscus paramutabilis x mutabilis. We made our final selection this fall, which we’ve christened Hibiscus ‘Tioga Party’. This 12′ tall x 12′ wide beast puts on quite a show, starting several weeks

Iron Clad Hybrids

Up until a couple of years ago, we could find no literature detailing any hybrids in the cast iron plant genus, Aspidistra.

These are a fascinating man-made group of hybrids between two South African genera of bulbs, Amaryllis belladonna and Nerine, first described in 1961.

Summer Maid

Looking lovely in the early fall garden are the xAmarcrinum. These are man-made hybrids between Crinum lilies and the South African Amaryllis belladonna. Despite the later not growing well here, the hybrids are quite amazing with their sweetly-fragranced flowers. All xAmarcrinum are somewhat similar in growth, with greatly reduced foliage from most crinum parents. The
