Planting begins!

This weekend I started sowing a few seeds indoors under the grow lights. I've been feeling hunger pangs for spring greens lately, and I found in my seed bucket an unopened package of "micro greens" -- a freebie from the folks at Botanical Interests. Inside is a mix of beets, cabbage, Swiss chard, kohlrabi and pak choy seeds. All these things, even in miniature form, would ease my craving just fine. Really, though, I think this is more about the urge to coax to life a few tender greens, even if it's not yet enough for a full-bowl salad. The instructions say the seeds can be started inside "anytime under proper lighting." So here we go!

I also planted seeds of Blue Solaize Leeks, and for flowers, I started snapdragons and petunias. I never imagined I'd become a petunia grower -- those things are a dime a dozen at garden centers -- but the previous owner of the house had petunias planted when we moved in, and I saved some of the seeds last fall. I'm working on free plants for the flower boxes along the deck.
Speaking of flower boxes, I'm trying to think of a combination of plants that I could put in the flower boxes at the front the house. It's north-facing, no direct sun, and the boxes, I anticipate, will be dry more often than moist. Any suggestions for good flower combos in such conditions?
