According to Wikipedia, there are 260 species in the genus Gladiolus, of which 250 are native to Sub-Saharan Africa, mostly South Africa, the rest of which are native to Eurasia. The types that we have for our gardens are nursery hybrids.In one section I have a few pale peach, yellow and orange. In another section I have mixed peach, orange, pink, rose, red and dark red. Some of the varieties have one solid color, but some others have two or three tones. Some of these are 4-5′ tall- these pinks are about 3 1/2′ tall. These plants will generally need staking, which can be done around the whole group. If the blooms get too wet they will get top heavy, and flop over, so I try to just water them at the dirt level. Be happy, grow glads :).
