Ball seed company used to sponsor a horticulture school in Geneva IL is it still there?

There is a listing for a Ball Seed Company in Hartford, Wisconsin.

= Ball Seed Co =

537 Sunset Dr, Hartford, WI 53027-2321

There is also a Ball Horticultural company whose website is http://www.ballhort.com

and they have introduced many innovative, award-winning varieties to the world of horticulture, including Wave Petunias.

Without further information, I'm not sure which "Ball seed company" for which you are searching. The school name was The DuPage Horticultural School. It is no longer in existence.
