With spring upon us, we are in full gardening swing. Bulbs have popped out of the ground, and perennials are beginning to show themselves. This is a great time to peek around your garden and begin planning new or replacement plantings.

Before it is time to get your annuals in the ground, April is a great time to get some perennials started right in your garden. Seeds are a very affordable option for filling your gardens with fresh plants. Aside from seeds, all you need is a water source and a small trowel or rake to get your seeds started!

Below are some of my favorite perennial flowers that you can sow directly into your gardens in the month of April. Enjoy the process of growing your own beautiful plants but remember these plants may not bloom in the first season!

Black-eyed Susan

Wait until your temperatures reach 60 degrees consecutively. Press the seeds into the soil about ¼ inch deep. Keep the soil moist and await germination, which should take place within a month.
