Answer: Go ahead and prepare your planting bed, then direct sow the seeds of your perennials. The plants will grow this season, but won't flower until next year. Work some organic matter into your soil, to both retain moisture and release nutrients to the roots of your new little plants. Don't let weeds compete for sunlight, moisture or nutrients with your new perennials and they'll grow contentedly until frost. Next year they'll be ready to burst forth with bloom as soon as the weather signals them that spring has arrived.
