I have Hedychium coccineum, Orange Bottlebrush and Hedychium coronarium White Garland Lily Ginger) happily growing and blooming.


Three questions:

1) How or should I remove the faded blooms??
If I cut them off - how far down. the orange one is in the seven to eight foot range.
(Nope it never got that tall before but this year some Super Thrive got ton some and well - now I have 7' - 8 ' Gingers)

2) Is the White Garland Lily Ginger root edible?

and lastly,

3) Can the grocery store variety of ginger root grow and bloom also?
