Annuals That Self-Sow!

Standard

20150424The very best annuals are those that self-sow…  At least that’s my opinion as a laidback gardener. You sow them the first year, directly in the ground where you want them to grow, in either early spring or mid-automn, then they come back year after year from seeds that fall to the ground around the mother plant. Compared to the more common bedding annuals you have to start indoors and transplant into the garden year after year, it’s much less work! And much less expense too!

Obviously, for annuals to be able to self-sow, you need to do two things.

First, don’t deadhead them. After all, if you suppress their fading flowers, where will next year’s seeds come from?

Secondly, leave at least a few spaces free of mulch. Mulch is a great product and I use it abundantly, but it does prevent seeds from germinating.

Here are a few of the annuals that self-sow faithfully for me:
