I bought some Sweet Rocket (Hesperis matronalis) seed a couple months ago and never got around to putting it in the garden. Do you think it's too late? I'm in zone 6a, Chicago suburbs. Thanks!

and we've got to get ourselves back to the garden. ~ Joni Mitchell ~
Sherri, the Hesperis matronalis can be sown the year round. I'm in zone 6 too, and the plants are self sowing the year round. It might be a little too late to get blooms this year, but you will certainly have blooming plants next year.
