I want to try starting perennials from seed, since I can't afford to buy all the plants I need to fill an area we cleared 2 years ago. I could use both sun & shade plants, including hopefully some vigorous groundcovers. Please send me your ideas for perennials that grow well from seed. (I have had good results starting veggies from seed.) Some I am thinking of trying (because I like them and purchased plants have been successful here) include: lavender, mondarda, ajuga, alchemilla, asarum europaeum, lysimachia. What would be some good first experiments at planting a few dozen plants?

Also -- what are some good perennial seed suppliers, or what do I look for (or avoid)?
