I usually plant my butterfly gingers with the rhizomes a couple of inches below the surface of the ground. This helps to keep them from falling over while they are getting established.

I have better results when I give the butterfly gingers morning sun and afternoon shade or full sun morning and evening but shade thru the midday hours. I also have some growing in almost full sun. They grow into a stockier plant that way, but they just aren't as nice looking. No matter which, they are bound to multiply and then you can put them in lots of locations until you find one they really like.

Eken gives good advice. The ginger bloom is like ice cream, they seem to melt in the hot sun. Give them afternoon shade if possible.

thanks a bunch guys. i think i have just the spot!

Hawaiian ginger bulbs grew great! Now what? Do I cut down the dead stalks at the level of earth? A few inches above? What else do they need? I need all of the help I can get!

You can probably just pull the dead stalks off of the rhizomes for easy cleanup. If your rhizomes have become exposed overground, cover them up lightly with soil. Hedychiums love water and fertilizer once they have become established. If you water too much before they get going good the rhizomes will rot.
I have most of my hedys in full sun because they do get plenty of water. Those that have too much shade have less than good results for me.

Brought my "hawaiian white ginger in 2 weeks ago and it is doing fantastic, never thought I could grow this plant here in Ohio, just ordered a red ginger plant...hope it does just as well

I lived in Galveston county Texas and have clay soil. I planted Pink ginger, butterfly ginger and shampoo or pine cone ginger. Each rhizome was about 6 inches long. I ended up with over 150 sq feet of ginger plants. It was planted under an elm tree (moderate shade, on the west side of the house under the eaves(dew drip every A.M. and in clay pots. It all did very well including coming back after a 23 degree week of freezing weather! I have now moved to Florida and wish I had brought some rhizomes with me!!!
