Not planted yet; Too early to evaluate.

Really love this cheery wildflower! My favorite part, is in the morning when I go out to the garden about 10 or so male long-horned bees (Melissodes spp.) are asleep all cuddled together around the flower disc having a sleepover. It’s pretty cute, as these bees usually are solitary in nature, but not when sleeping on this rudbeckia apparently! Zone 5, high desert, Central Oregon.

I absolutely love this company! Seeds are very productive and seed packages are lovely! If you have questions, these folks are always so helpful! I highly recommend them for all your seed needs (or if you’re like me - wants). Thank you Botanical Interests!

After my previous review, the rudbeckia will really let you know when they are ready to flower! The native bees love it and are so cute when covered in pollen! No issue growing them what so ever.
