Whatever it is I like it!

Lovely plant! I bought the seeds based on the description that said perennial. I’m z5 and hope they make it through.. For a perennial they all started blooming super early and it has been nonstop even though it os end of September! Made me look on the page to make sure it was NOT an annual. Blooms were incredibly long lasting, lots of pollinators visited. Visitors all commented on their unique appearance. The seedlings all thrived so I gave a bunch away at a garden club party which made people very happy! So all around good, great if they make it through the winter!

A very nice flower

I've grown "Prairie Sun" for several years. While it is a Rudbeckia I treat it as an annual for our zone (5). I start the seeds in a stratified germination mix (end of March) and transfer the seedlings to high-porosity growing mix under lights until we're past frost (usually mid-may). This year the seed is film coated so it's easier to see in my potting soil. For the past several years Pine Tree (Super Seeds) has offered the best per seed cost for this variety. I specially appreciate their service. Folks are always impressed with the two-toned color of this flower!

Always growing prairie sun

This plant has been in my garden every year since I started growing it over 10 years ago. These self sow too. I grow it's sister, Indian summer too. It's easy to grow and pest free. Watch out for woodchuck though cause they love to eat the leaves.

Rudbeckia- Prairie Sun

The flowers were a beautiful lemon- yellow. I had started them late winter (2017) inside and they were slow growing there. I did not have a good grow light which most likely was the reason they were so slow. Consequently the did not begin to bloom in my garden until August. Tried to grow them since I have been unable to find them as plants at garden centers
