This is the first seed that we are going to sow for the new season Autumn Jump Starter.
Sweet Rocket (Hesperis matronalis) is a biennial and can be sown in the summer, but I find it a lot less hassle to grow with the hardy annuals.
Not all biennials respond as well to being sown in Autumn but this one has never let me down.
