Productive and decorative! A handsome bush with three seasons of interest: white, pink-tinged spring flowers; large, light blue summer fruit; and vibrant orange and yellow fall foliage. The large berries, often reaching the size of quarters, are produced in great abundance and have a delicious, tangy-sweet flavor. Blooms late to avoid spring frosts. Also makes a very attractive and decorative hedge! Early season. Originates from Beltsville, Maryland, introduced in 1985. Cold-hardy. Ripens late May. Self-pollinating.

Recommended Spacing

We recommend spacing these plants 4 - 6' apart to ensure room for growth.

What do you mean by 4 inch stark pot vs 1 gallon container? Is this just the container size or also the size of the plant?
Nigel D on Mar 9, 2016
BEST ANSWER: Both. The 4-inch potted blueberry plants will be about 4-6 inches tall when they arrive and the gallon-potted blueberry plants will be more mature ??? up to 12 inches tall when they arrive. Both options have a well-developed root system within the pot for your transplanting success.
Your dwarf blueberries, are you going to produce fruits this year?I leave in 07646. Thank you.
Ming A on May 6, 2019
BEST ANSWER: I will be able to let the two Duke blueberry plants I bought last year produce fruit this year since they are at least 2 1/2 feet tall. Google Michigan State University on how to avoid a common blueberry planting error. Stark Bros does not show the correct way. You can also google how to properly plant blueberry bushes and watch/read some other information. I also followed how to fertilize and mulch the blueberry bushes on some other websites rather than Stark Bros. I use organic fertilizer/acidifier. I also bought 2 each of Patriot, Herbert and Elliot from Stark Bros. The Herberts are slow starters as they are late bloomers. One of the Herbert plants they sent me had barely any roots and I bought the more expensive 1 gallon plants. They did replace it, but they should have never sent me a dead bush & it was like they stuck a one pint plant in some soil and sent it out. Otherwise, so far we're happy with the plants and they are thriving and we hope they continue to do so. We will not let the Herberts produce fruit this year since they are not at least 2 1/2 feet tall per Ohio State University extension website. Enjoy!

Do I have to plant another variety of berry alongside this duke berry for pollination purposes?
Anits S on Aug 25, 2016
BEST ANSWER: Thank you for your question.You don't need another variety for pollination with this variety. You would get fruit with only one plant, but adding a pollinator will give you bigger fruit, and more of it. If you like to discuss pollination options further please call our Customer Support Department at 800.325.4180.
Are the plants and berries disease resistant(mummy berry) and also would it be safe to plant these bushes where my other bushes were?
SUPERMAN on May 21, 2016

Duke blueberry
Love this variety of blueberry, it is the earliest to ripen with very large fruit and very sweet flavor.

Early but no flavor
I purchased Duke from a local nursery (not Starks), but feel compelled to warn others about this variety. I planted a large plant from pot in a raised bed with pH adjusted to ~4.5-5.5, mulched with pine needles in southern Illinois. The berries were mid sized, and very early. But they had absolutely no flavor, especially compared to the Bluecrop and Blueray raised in the same bed. Early is nice, but with no flavor, I'll be removing this plant and replacing with something more flavorful.
