The first Cassady grapevine sprang up as a volunteer (unplanted) seedling in the yard of P.H.
It did not bear fruit for five years, but when it finally did, the grapes it produced were found by Cassady to be juicy, pleasantly flavoured, and of very good quality.
The original description of the Cassady grape was published in November 1853 on page 563 of The Magazine of Horticulture, Botany, and All Useful Discoveries and Improvements in Rural Affairs, Vol.
