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


A different species of Japanese maple, the Green Cascade Japanese Maple has larger leaves and greater resistance to sun-scorch than its delicate relatives. As well, left alone it will form a spreading mound, not a tree, making it ideal for cascading down banks, over walls, or out of tall pots. With its wonderful fall color this is a must-have tree to enjoy vibrant gold, orange and reds splashed across the leaves. No other tree will flow like a stream down your garden and give such an exotic and stunning fall effect.

• Prostrate, cascading form ideal for banks and walls
• Good scorch-resistance in sunny spots
• Great choice for warmer regions
• Outstanding fall colors
• Easy-care garden feature

Although it will naturally stay low, if you want a taller Japanese maple with weeping branches, it is easy to stake this tree upright to get more height with a full weeping effect. Although a different species, the Green Cascade Japanese Maple still has the special leaves like an outspread hand, of Japanese maples, but they are larger and so even more outstanding.

The plants we know as Japanese Maples come from a fairly large subgroup of the Maple tree family (Acer) that’s native to Japan, China and the surrounding areas. A wide variety of these trees have been cultivated in Japan for centuries, and with the growth of trade between Japan and the outside world in the 19th century they soon became a popular feature of gardens around the world. One popular and attractive species of Japanese Maple is Acer japonicum, and in particular the variety known as “Green Cascade.”

Japanese Maples come in a wide range of sizes, shapes and even colors – there are some varieties with spectacular red foliage. This variety makes the family incredibly useful to gardeners because there’s one to suit just about anything you want to do. Whether you’re looking for a shade tree, a colorful accent to enhance the trees around it or a compact centerpiece for a smaller space, a Japanese Maple that fits the bill can be found. If you’re looking for a Maple to fit a more confined space we highly recommend Green Cascade.

Growing Green Cascade Japanese Maple Trees

Green Cascade is a small Maple; in the first ten years it usually only reaches a height of between four and five feet, but when fully mature it should be at least ten and sometimes up to 20 feet tall. It’s quite a wide plant, too – when mature it usually spreads out to between 15 and 25 feet wide. Often it splits into multiple trunks just above ground level. What makes its form so attractive is hinted at by its name – the branches curve out in an impressive cascade, stronger-looking than a traditional weeping form but every bit as alluring to the eye. It spreads relatively quickly; instead of a dense bush, when young it shows a more open, almost sprawling shape. It does become much denser with age.

The leaves are elegant – finely divided, delicately veined and prolific. In spring and summer they display a bold green color, soon enhanced with striking red flowers that begin to appear in early April. After the flowers come, a plentiful crop of samaras (winged seed pods) that ripen through late summer and take on a red hue of their own. In fall these provide a rich food source for a variety of birds. By this time the tree itself is adopting its fall colors of vivid crimsons and yellows, bringing the outdoor months to a glorious close. Its final charm is that even in winter it remains attractive, with its branches forming an intricate silver-gray tracery. Winter gardens can be bleak, but a Green Cascade will ensure there’s still something worth looking at.

Hardiness and Climate

Although the Green Cascade isn’t quite as robust as some other Maples, it can still be successfully grown through most of the USA. It’s suitable for USDA hardiness zones 5 to 7, so it should do well down most of the East Coast (apart from New England) through the southern and central Midwest and across much of the west. Anywhere with a decent amount of rainfall is a suitable environment for it. Late frost can be a problem though. The foliage tends to open quite early in spring and is vulnerable to damage if there’s a last cold snap. While the tree is small consider protecting it in winter with a burlap frame filled with dry leaves.

Soil Conditions

Like other varieties of Maple trees, the Green Cascade prefers acidic soil although it can tolerate neutral pH levels as well. If your soil is neutral consider digging in some peat moss before planting; if it’s slightly alkaline you can improve it with some powdered rock sulfur. The soil does need to be moist and well drained; this tree won’t tolerate dry ground.

Planting Location and Sun Exposure

When looking for a spot to plant your Green Cascade Maple consider sunlight carefully. It can handle full sun as long as it’s not too intense, but in southern states it may scorch in summer. It’s better to find somewhere that offers partial cover; the dappled shade of a larger tree is ideal. Also think about exposure to winter weather, as too much cold wind can cause damage. If it is going to be in direct sunlight try to ensure it will have sun in the morning and shade in the afternoon.

Care and Maintenance

In general, the Japanese Maple (including the Green Cascade), is quite an easy tree to look after. It doesn’t require pruning, although if it spreads too far it’s simple enough. Just ensure you prune after the danger of frost is gone, and no later than early summer. Aphids, scale, borers and caterpillars are potential pests, so check occasionally and use a suitable treatment if any are found. Add organic mulch in summer to keep the roots moist.

Green Cascade is a very attractive tree that’s perfect as an understory to larger species or as a centerpiece in a smaller garden. It puts on a good show all year but is especially magnificent in fall. It also attracts songbirds and beneficial insects, so we highly recommend it.
