Chester Thornless Blackberry

This variety is a great all-around blackberry — firm but not tart. It is the most productive plant of its kind that you can grow in the upper Midwest. Fruit won’t soften, leak or lose color in the South either. Ripens in July. Self-pollinating.

AnnouncementClose

We have some big news...We're joining with Stark Bro's!

Dear Friends,

I'm very excited to announce that after 75 years, Miller Nurseries will now become part of Stark Bro's, a highly respected nursery company that's been "growing" their famous legacy since 1816.

Who is Stark Bro's?

For nearly 200 years, Stark Bro's has been producing high-quality fruit trees, berries and garden plants for gardeners like you. With their great nursery stock and expert advice, they've been helping generations of families reap not only the rewards of growing their own fruits and nuts, but to enjoy huge savings in the process. Stark Bro's has a long-standing reputation for quality, honesty and really taking care of their customers.

When my brother David passed away suddenly last spring, I knew it was time to retire. One of the first things I did was to call Cameron Brown, the president of Stark Bro's. He is a long-time friend and a very trustworthy fellow, and treats his customers like gold. I knew he would take care of you in exactly the same way. David would have liked this arrangement, and I take comfort in that.

What's going to happen to Miller Nurseries and my customer account?

It's only going to get better as part of the Stark Bro's family. You'll now be able to come here to StarkBros.com and sign in with your existing username and password, and purchase products just like you did on the Miller Nurseries website... only the selection will be much larger! You'll still be able to buy Miller's familiar "Canandaigua Quality" hardy plants as well as the enormous assortment of trees and plants Stark Bro's offers.

We want to take this opportunity to acknowledge our family, our wonderful employees, and especially you - our loyal customers - for your support and patronage over these last 75 years. Thank you for being such an important part of our heritage.

Warm regards,
John Miller, CEO
Miller Nurseries
