The queen of the yellow plums!

A true standout, in both looks and flavor. The beautiful translucent yellow skin reveals juicy, sweet flesh of the same color. Expect large crops from this tree, which sports clusters of sunny golden fruit up and down all of the branches, rather than just at the tips.  of plums all throughout the tree. Heat-tolerant. Clingstone. Introduced to America in 1899. Ripens in late July.

How do I find my Hardiness Zone?

Canada’s Plant Hardiness Zones will tell you which plants will do well in your particular climate. Each zone is determined by the lowest average winter temperature recorded in a given area. Hardiness Zone information is included on all tree and plant product pages, so you know instantly whether a certain plant is likely to succeed where you live.

  1. Kevin Gilligan –

    Doing great in Tucson and I couldn’t be happier with it.

  2. ERIC SCHULLEK –

    I am glad to get my 7th plum tree for my garden as my first stark bros order. The bareroot tree came fast, good quality and a good price. I recommend 5/5

  3. Ying Zhao –

    I purchased one Shiro Plum Standard and one Shiro Plum Dwarf in Feb 2017, planted them 100 feet away. From late July to the first 10 days of August 2019. We harvested around 30 Lbs from the Standard and 10 Lbs from the Dwarf. The fruits from two trees are exactly the same taste and same size. They very sweet and juicy. I can’t describe how good they are. My family and friends all love them! If you want to buy several trees, I recommend you should include at least one of this and another one the same or different plum for pollination. My area is 8A in WA. The trees are very healthy without needed to spray anything. In 2018, only the Standard plum had flower but no fruit. In 2019 both Standard and Dwarf had flower and produced fruits, so I think pollination is important and can be as far as 100 feet where the two trees are. I have only peach and cherry trees near by the Standard. In summer 2019, the Standard grew to 12 feet but I cut the tops, and the Dwarf grew to 8 feet. There is no doubt that they will have another good production year in 2020 just by observing them now.

  4. Bassam Mohammed –

    Dead within first year, Starkbos promised to replace once available.

  5. Kate Brister –

    I’ve grown a wide variety of fruit trees in my life- NONE come even close to the productivity of this tree! Mediocre soil, high summer temps, and a mild winter- but I have well over 1000 golf ball sized plums (after thinning!!) on a 4 year old tree. Stands about 14’ tall Best flavor fresh, amazing jam, and fantastic to infuse into vodka :)

  6. Paul Wichert –

    It grew so fast, I had to transplant it at the end of the season, out back where my other plum tree is located. It has taken there and seems to be healthy. A little slow to flower this spring but what else would you expect after being uprooted in October?

  7. GUNTHER FISCHER –

    I really can’t judge the Shiro plum as it is only about 2 – 3 years old and has not produced fruit yet.

  8. JIMMY SEALS –

    Plum trees (2) are doing really good. Have no fruit yet but and living and have a dark green color. Seems to be at home. Thank you.

  9. Cat Leatherwood –

    I ordered my trees at least a year ago. They overwintered in a large pot, and are now planted. So far, they’re strong, and I look forward to my first plums.

  10. Irina Pank –

    Excellent growth, added bunch of new branches, bloomed too.

Tree Sizes

It is essential that you choose the right size for your space. Whether you’re planting an acre, a suburban yard or a small urban plot, we’ve got the perfect size tree for you. When they mature, they will be one of three sizes*:

dwarf
dwarf

Dwarf

Grows to be about 2.5-3 m (approximately 8-10′) tall and wide. Provides a bounty of full-sized fruit in a small amount of space.

semi-dwarf
semi-dwarf

Semi-Dwarf

Grows to be about 3.5-4.5 m (approximately 12-15′) tall and wide. Produces the maximum crop per square foot of growing area. The majority of the fruit can be harvested from the ground, with no need for a ladder.

standard

Standard & Unmarked

Grows to be at least 5.5 m (approximately 18′) tall and wide. Standard nectarine and peach trees grow to be 3.5-4.5 m (approximately 12-15′) tall and wide. Standard trees serve two purposes: they provide both fruit and shade.

* Tree sizes may vary by variety.

Potted Trees

potted tree

EZ Start® Potted Trees

Trees that are grown in a bottomless 4x4x10″ pot, which encourages dense feeder-root growth for a quick, strong establishment. When shipped, they are about 1½ – 3′ tall.

Supreme EZ Start® Potted Trees

Top-grade trees are grown in a bottomless 5x5x12″ pot, which creates an advanced root system comparable to that of a three-year-old tree. When shipped to you, they are about 3 – 4′ tall.

Supreme XL Potted Trees

Our biggest and most robust potted trees. Grown in a 9x9x12″ pot filled with high-grade soil, these trees are even larger than our Supreme EZ Start® trees. When shipped to you, they are 4-5′ tall.

Bare-Root Trees

bare-root

Stark Supreme Tree®

This season’s top-grade, bare-root trees that give you a head start on growing. When shipped, they are about 4-5′ tall and/or with a 5/8″ or larger trunk diameter.

Supreme XL Trees

We don’t call them “XL” for nothing! Supreme XL trees are our biggest and most robust bare-root trees: they ship 5-6′ tall and/or with a 1″ or larger trunk diameter.

USDA Certified Organic Trees

organic

If you’re inclined toward organic gardening, browse our selection of non-GMO, certified USDA Organic fruit trees. Our fields and trees undergo annual inspection to maintain their certification, and are grown without chemical fertilizers, pesticides or herbicides on pure pastureland.

Grafted Trees

graft

Grafting is the process of taking cuttings from a single “parent” tree known for its fruit taste, size, bloom period and ripening time, and joining it with the root system and trunk base (rootstock) of another tree also known for its desirable qualities. This process has been used for thousands of years to produce fruit that is consistent in flavor, shape and size.

Most of our trees are grafted, creating this kind of consistency and allowing us to produce different mature tree sizes. While seed-grown fruit trees might give you unpredictable variations or a lack of results, grafted trees will give you the fruit you want and the tree size you expect.

Stark® Custom Graft® Trees

Limited space doesn’t have to mean a limited selection of fruit. Stark® Custom Graft® fruit trees have two (or more) varieties carefully grafted onto one tree. These multi-grafted fruit trees require less space to grow than separate trees, and also provide compatible pollinators — built right in! To ensure success growing multiple varieties on your Stark® Custom Graft® fruit trees, be sure to prune to keep all varieties in balance.

Other Terminology

Professional Pruning

Pruning is one of the most important ways to help ensure that your tree gets off to the right start and has the best chance for success. That’s why Stark Bro’s professionals prune many of our fruit trees before shipment — at no cost to you!

We get you started, but you will need to prune throughout the life of your tree. Doing so will help eliminate extra buds that can slow development and allow your tree to form a strong framework by removing weak, narrow and competing branches. Proper pruning will give your tree the perfect shape and branching structure for maximum fruit production.

Self-pollinating

Indicates tree or plant will pollinate itself and doesn’t need another tree or plant near it in order to bear fruit. In many cases, you may still want to plant pollinating partners to increase the size of your crops, but with self-pollinating varieties doing so is optional. You’ll get fruit with only one tree!

Starkspur®

A Stark patented product since 1952! “Spurs” mean bigger harvests! Starkspur® trees are different from regular trees which bear fruit only on the outside limbs. The spur allows fruit to form on each limb and bear from the trunk out – doubling the amount of fruit.

Stark® Colonnade®

Grow full-sized fruit on narrow columnar-shaped trees. Perfect for growing fruit on a balcony, patio, or sliver of ground – even if you live in an apartment or condo. They make a particularly impressive “living fence” when planted in a row – consider using them to disguise eyesores on your property and grow fruit at the same time!
