Seed varieties can be overwhelming

There are so many different types of seeds available to us now. It is a bit overwhelming. Not only are there different varieties of the same plant, there are different ways the seeds are produced. There are cultivar (cultivated variety which can be a hybrid or open-pollinated); genetically engineered; genetically modified; open-pollinated; hybrid; heirloom and of course organic. For more information on this, visit  www.ezfromseed.org/.
It is time, actually past time, to plant peas, potatoes, lettuce, onions, radishes and parsley and of course the greens: spinach, Swiss chard, kale. I'm getting late season seeds from http://reneesgarden.com/ again this year.
It has been so wet, we're losing another weekend of potential planting. For those who have time during the week, it looks like Tuesday or Wednesday will be the first good gardening opportunity. For those who have already planted, good for you. Hopefully you didn't plant too close to this massive non-stop marsh-creating rain streak.
The plants aforementioned can actually be planted outside as soon as the ground is workable, usually in  mid-March. (This year, it was the first week of April for us and then the rain set in.) We never plant before the end of March. One thing I've seen that is if it's cold, the plants will grow slow, defeating the early planting time. We could plant broccoli, cabbage, celery, kahlrabi, Brussels spouts and cauliflower plants outside at this time.
We will wait until mid-May to plant beans and squash seeds. Then, late May to plant the eggplant, peppers and tomato plants.
