Hedychium

[CG100]

Does anyone grow any?

Here in the UK many are hardy, but for most of the country if they are grown outdoors, in the ground, they go completely dormant during winter and the growing season is too short for them to flower. Far better to grow them in pots and keep them frost-free and get them into growth early with some extra warmth, even if provided simply by a greenhouse warmed by spring sunshine.

I have several species and most only seem to produce 1, 2, 3 shoots from new rhizome each spring, even if there is plenty of healthy older rhizome in the pot. Is this normal?

How are the pots that frequently appear online, with several growths in an 8-10-12 inch pot, produced?
