But if you fail to get an early jump, don’t despair, just plant
it between your rows and fertilize while you grow. Plants should
be tilled in or cut off and allowed to re-grow, before seed pods
begin to fill. Fall planting works well even in northern states
where plants can be allowed to freeze off. Plan extra seed for use
in your garden, flowerbeds and areas of lawn that need replanting.
Even better, it is not a weed.
It will not invade your garden or return as an obnoxious weed.
And being a fine leafed plant it will till in with ease; no big
machinery is required. With all of these benefits and ease of use
one would not expect 1” flowers that range in colors from
white to blue and pink to purple all on the same plant to liven
up your garden. While it does good things for your soil it is not
intended for human consumption.
