The Green Finger is one of the best tasting Cucumis sativus varieties that I have had. Though it looks somewhat like a Beit Alpha type, its moderately thin skin is not as wrinkly as a Beit Alpha, though its flesh has much more of a Umami-type filling flavor than I have encountered in regular cucumbers.
The production of this variety is not as good as some others I have grown. Compared with a lot of other varieties, the Green Finger definitely puts taste above production.
Another other thing about this variety that I learned from growing it late into the season is that it had relatively good disease resistance, at least to Powdery Mildew, which was rampant around the rest of the cucumbers and melons in the garden in September.
