You will receive THREE nice sized Shell Ginger (Alpinia zerumbet) rhizomes.  I would suggest planting each one in a gallon size container or larger if not planting directly in your tropical garden. 
This ginger can be grown as a house plant or can  be planted in your landscape in a shady or partly sunny part of the yard.   With it's emerald green leaves reaching 9-10 feet tall, this is certainly one  of the most dramatic Gingers for impact in your house or landscape . Excellent in containers  or  your shady to partly sunny tropical landscape, shell gingers bloom in mid to late summer with fragrant shell-like flowers. The unopened flowers look like  strands of threaded pink seashells.  When they are open, they seem to contain tiny orchids  with yellow and orange markings. A wonderful addition to any ginger collection!   
These plants can reach 9'-10 feet tall in the landscape and make excellent  background plants or feature plants in your shade garden. Hardy to zone 8 grow as a container plant or lift rhizome in the winter in colder zones.
