Well I couldn’t find any vegetables we’ve grown that started with D, except Daikon radishes but that will be under R.
My apologies that this collection pf pics is sorely missing some veggies, like kohlrabi and kale, and the okra is larger than we want, but we promise to plant some seeds and get those pics up asap.
Also, although ground cherries are related to tomatoes, we put them here and will link them on that post. Similarly, but just the opposite, tomatillos.
Just click on the pictures for a larger view. Hopes this helps if you need to ID a seedling!
