Hi, These plants are not exactly "bulbs" but they must surely be geophytes. I have grown 4 types, and they all like lots of fertilizer (compost, or aged manure is perfect), and they like moist soil, even if it means occasional flooding. I have grown, but no longer have, the old pass-along plant, the white and very fragrant Southern plant (H. coronarium), and I have 3 hybrids/selections. 1. Hedychium x 'Daniel Weeks', early blooming (first week of July), cream and orange, some fragrance 2. Hedychium densiflorum 'Tara', salmon orange, fragrant, early, 5-6 ft. tall. 3. Hedychium x 'Elizabeth', 8 ft. tall, orange, fragrant. They are 2 years in the ground and 'Elizabeth' has not bloomed and has not yet reached 8 ft. in height. But, I'm hoping for big things. They are all in sandy soil, and I think that nutrients are leached out too quickly. Aged cow manure has helped this year and I'll keep adding it as it is depleted. Fish emulsion is a problem, it brings out too many raccoon and possum, and maybe other things; the leftover scent drives the dogs wild and the holes that the wild animals dig are a nuisance. Here is a link to 'Elizabeth' at Plant Delights http://plantdelights.com/Catalog/Current/… The description makes me want to quit work and follow the bloom cycle around the globe from Northern to Southern hemisphere. I've really got to learn how to write the way they do for that catalog; always enticing and (I have to agree) correct, but the verbs and adjectives are more than I can bear on some days (oh well). I'm looking for a trade or two. You know what plants I have and if you want something special, and have a great ginger lily trade, I'll order what you want. Plant Delights seems to have an endless selection of species and hybrids. These plants love our long, hot summers; they do well in full sun if they have lots of water. I enjoy seasonal flooding at the back of my lot, and grow cattails in the low areas and ginger lilies in between. However, these plants don't need "wet," they only need the type of irrigation that you might give to hybrid tea roses--and about the same amount of fertilizer for best bloom and growth. Here, near Houston, I've never seen insect problems or disease. Similarly, the H. coronarium was bulletproof in Alabama, and came back year after year, even when temperatures dropped to 3 F (-16 C). Cordially, Joe Shaw
