It's best to soak your Bluebonnet seeds prior to sowing. Prepare a shallow dish, like a pie pan, with 1/2" of very warm tap water (out of the faucet hot - do not exceed 140 degrees). Place your seeds in the warm water and let your seeds soak for at least 24 hours.
The best time to sow is in mid fall, but you can also direct sow them anytime from fall to very early spring. When direct sowing work your garden beds 6" deep and then sow the seeds on the surface as they need light to germinate. Once sown lightly dust your seeds with peat or compost.
Like other spikey type flowers, such as Foxglove and Delphinium, Bluebonnets are mildly toxic and care should given if exposed to children or pets that consume large quantities of your garden flowers.
