Answer: Perennial seeds are often sown in the spring so they have an entire season to grow. Some will even flower the first summer if given an early enough start. But, you can sow seeds outdoors throughout the spring and summer months. You can also sow outdoors in the fall, but some plants may not be mature enough to make it through the winter. The advantage of sowing seeds in pots is that you can properly space the plants when it's time for them to go out into the garden. On the other hand, seeds sown directly in the garden can be thinned and the thinnings transplanted if the plants are too close together. I always sow my seeds directly in a prepared garden bed in the spring, and I've always had good results. Why not try both ways and see which works best for you?
