- Ellen T.Verified ReviewerRated 5 out of 5 stars7/23/25My favorite flower this season!
I had never even heard of strawflowers but went for it this season and I love them! All of my flowers are from BI, but figured I’d leave the review here since they’re so fun and unique! I’m an absolute amateur and I would describe myself as a “wing it” gardener, so truly anyone can grow them!
Also had amazing success with dahlias, fireball zinnia, Tulsi basil, feverfew, and white marigolds!
