species pepo - summer squash, pumpkin, acorn squash
maxima – hubbard, buttercup, kabocha
moschata – butternut, Long Island Cheese
variety or cultivar Zephyr, Howden, Tiptop
Blue Ballet, bonbon
Green striped cushaw
- Also in the Cucurbitaceae family: Cucumis melo (cantaloupe),Cucumis sativa (cucumber), Citrullus vulgaris (watermelon )
Why is it important to know genus and species?
If the variety has characteristics that you want to maintain, you need to be aware of the issue of cross pollination, and, while plants typically cross easily within a species, they typically do not between species. So, while you can probably grow butternut, cushaw and a summer squash and have no crossing, your zucchini and Halloween pumpkin will cross.
Okay, now we have the pieces to the puzzle, how do we put them together?
