The dark belle is a hybrid ice box melon released from the the Known-You Seed
company (Taiwan). It has been field tested by Washington State University so
some one there may be able to supply more info. Seed quest only lists Green
Seed. Known-You http://www.knownyou.com/english.htm seems to limited to asia,
but some of thier cultivars like the Santa tomato have made to the North
American Market.
