Manu, the "ivy leaved" geraniums ...pelargonium peltatum...
is one variety that has many, many colors to adorn hanging baskets.

Ivy leaved geraniums are one of the most purchased varieties and should be found practically anywhere geranium is sold.

Perhaps a little finger walking through the lists of nurseries in your area would prove beneficial.

bamakrautie, you can mail order the Alpine geraniums from Wheeler's in Conneticut. Look them up on the internet. I think they start shipping in March. I am even thinking or ordering the Balcon or the cascading Alpine type. Good luck.
