How are the heights measured?

All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.

What is a gallon container?

Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.

How does the delivery process work?

All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!

Why are some states excluded from shipping?

The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.

About Me


The Oshio Beni Japanese Maple is a fast-growing small tree with outstanding foliage colors that change through the seasons. The spring leaves are a unique orange-red, turning garnet-red for most of the summer. In fall this tree explodes into brilliant scarlets. Reaching almost 20 feet in as little as 15 years, with an equal spread, grow this tree as a lawn specimen, or in a courtyard garden. Plant it in a woodland area, around your home, or at the back of garden beds. Of course, it is perfect for Asian-style gardens, containers, and bonsai too.

  • Garnet-red leaves are orange-red in spring
  • Powerful fall coloring of bright scarlets
  • Fast-growing to 20 feet or more
  • Grows well in partial shade and beneath larger trees
  • Classic ornamental tree for any garden

Hardy from zone 5 to 8, the Oshio Beni Japanese Maple grows best in rich, moist, well-drained soil in partial shade. It will grow in full sun in cooler zones, and with afternoon shade, or dappled full-shade in warmer zones. It normally has no pests or diseases and it responds well to pruning, which you can use to expose the trunks and create a more mature looking tree faster. A relatively easy tree to grow.

Some people think that Japanese maples are tricky trees, slow-growing, and just meant as small specimens, or for specialized gardeners. It is true there are some that remain small, and might need some extra care, but many are relatively easy to grow. Some are of course easier than others, and some, like the Oshio Beni Japanese Maple, are beautiful small trees that can (and should) be grown in almost any garden, only needing the same care as just about any other small tree. That doesn’t mean this isn’t a special plant. It has remarkable fall colors – the name means ‘big red tide’ – and in spring and early summer its wonderful orange-red leaves are a joy to see. It is easy to grow and fast growing, with a young tree becoming full-size within 15 years, adding as much as 18 inches a year to its height and spread, especially when growing in warmer zones.

The Oshio Beni Japanese Maple is a beautiful, small, multi-stem tree which grows to be 15 or 20 feet tall and about 20 feet wide. Its elegant rounded crown of dense branches grows from graceful, spreading stems, creating the very picture of garden beauty. If left to grow naturally it will be quite bushy, with branches to the ground, especially if grown as a specimen and not surrounded by other plants. You can also gradually remove the lower and inner branches to create a smaller number of main stems, topped with slender leafy branches, in a more tree-like form. Young twigs are smooth and glossy, with a red bark, and older stems are smooth and soft gray, often with narrow vertical wavy lines along them. In winter the bark colors and the form of the tree makes a very attractive winter profile, and a good reason to remove inner twigs and expose the trunks.

The leaves of the Oshio Beni Japanese Maple are 3 inches long, and divided into 7 slender, pointed lobes, spread out like the fingers of a hand. They are graceful and delicate looking, but compared to the leaves of many varieties of Japanese maple they are relatively sturdy, with broader lobes. This means the tree is more resistant to the shriveling of the foliage that can be a problem with these trees in hot summers. The leaves open in spring delicately folded, before spreading out. They are a gorgeous orange-red then, a unique coloring that creates a wonderful and bright tree. As spring turns into summer they darken to a rich garnet-red, and in the hottest months they may become more bronzy-green. Then, when colder nights arrive, and fall comes, the tree explodes into that ‘big red tide’ of brilliant scarlet, sweeping away all competition for the most brilliant fall leaves.

One of the best things about Japanese maple trees is their ability to grow in partial shade, in open woodland beneath mature tall trees. This is the perfect place to grow the Oshio Beni Japanese Maple, where it will fill the spaces beneath the towering trunks of large trees. It also grows well in the shade from buildings, and with its tougher leaves it grows well in full sun too, especially in cooler zones. In hot zones afternoons shade is beneficial, and the soil should not be too dry. This is a beautiful tree to grow as a specimen on a lawn, or around your home, looking wonderful against light-colored walls. Grow it in beds, with smaller shrubs and plants beneath it. Plant it to add beauty to a courtyard in an urban setting, and of course it is perfect for any space with an Asian theme. It is also wonderful growing in pots, handsome containers, or planter boxes – just make sure they have drainage holes. It also makes a classic bonsai tree, of almost any size.

The Oshio Beni Japanese Maple grows well in all but the coldest and hottest zones, thriving everywhere from zone 5 to zone 8. It should be planted in rich, moist, well-drained soil, and mulched regularly to keep the soil cool and moist. This tree is not very drought resistant, and it should be watered regularly during dry spells, especially in summer, but in spring too if it should be dry. Prepare the soil well when planting, enriching it with organic materials, and allow enough room for the mature spread of this tree. Japanese maples almost never suffer from pests or diseases, and they are easy, low-maintenance trees if the light conditions and soil moisture are taken care of. It is also easy and fun to prune it and develop an attractive, more mature-looking tree. Remove small, twiggy branches from the inside parts of the tree, as it grows, to expose the trunks and main stems. Shorten long stems that grow from the crown – cutting back to just above a pair of buds – to develop the characteristic dome-shaped crown of these trees. Late winter is the best time to prune, or through the winter months in zones 7 and 8.
