I dangle on to a bag of seeds and look forward to spring to sprinkle them round annuals for an additional pollen supply. Zinnias work nicely in clean areas of your backyard, too, the place different crops might have failed, or in spots that want an additional pop of colour that lasts all season lengthy.
