- Lisa B.Verified BuyerRated 5 out of 5 stars12/27/25Terrific late summer bloomer
Started in a raised bed according to package directions, and although a little slow to start, once these deep purple flowers started blooming they did not stop! (We've had an unseasonably warm fall and winter in Colorado this year) I kept deadheading, flowers kept blooming, and bees kept feeding until late November when I let seed heads form and sprinkled them on ground. Will definitely plant again next year.

Thank you so much for taking the time to share your wonderful experience with our Black Magic Bachelor's Button Seeds! We're absolutely thrilled to hear that those gorgeous deep purple flowers kept blooming non-stop for you once they got going! It sounds like you had the perfect combination of following the package directions and taking advantage of Colorado's warm fall weather. We love that you kept deadheading to encourage more blooms and that the bees were enjoying them right up until November - what a fantastic pollinator garden! Your smart thinking to let the seed heads form and scatter them for next year shows you're a seasoned gardener. Thank you for choosing us and for sharing your growing success with us. Keep on growing 🌻️

Winter sown on 02/09 and bursting thru the hole in the bottle on 03/22. The bottle is half black magic and half another variety. Very pleased so far. First time growing these and first time winter sowing.
