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.
The Mimosa Silk Tree is that wonderful thing, a tree that is incredibly beautiful, fast-growing, and yet easy to care for. The leaves are divided repeatedly into many small leaflets, giving it a wonderful ferny look, and they fold up at night, in rain, and when touched. The exotic, showy flowers look like pink powder puffs, or the crest of an African bird, and a tree in bloom is stunning. Flattened seed pods decorate the branches in winter, and the broad, spreading crown makes this tree a great choice for a quick shade tree. Use if for those difficult dry locations, where the occasional deep soak is all it needs to thrive.
- Flamboyant pink, powder-puff flowers in summer
- Finely-divided ferny foliage ‘goes to sleep’ at night
- Broad, umbrella crown casts a wide shadow
- Tough and reliable in hot, dry locations
- Fast growing even on poor ground
Plant the Mimosa Silk Tree in full sun, although it will tolerate a couple of hours of shade if it must. It grows well in any well-drained soil, acid or alkaline, from sand to clay, and on poor, dry soil too. It has no pests, and deer leave it alone. If necessary, prune in spring, just as the new growth is beginning, and train it to a single trunk, or leave several stems for a multi-stemmed look.
- Plant Hardiness Zones 6-10
- Mature Width 20-50
- Mature Height 20-25
- Sun Needs Full Sun
If you need to garden in a hurry, fast-growing trees are a must. Sadly, many of them are simply sticks with leaves, that do grow fast, but don’t have the grace and beauty of trees that grow more slowly. While the Mimosa Silk Tree is fast-growing, adding a good 3 feet of extension every year when young, it is also amazingly beautiful. The ferny leaves on a broad umbrella of branches; the remarkable and unique pink fluffy seed heads; and even the long seed pods that decorate it in winter – all these things make for an outstanding, fast-growing plant for new gardens, and older ones too, bringing beauty and interest.
The Mimosa Silk Tree grows quickly into a small tree with a broad, spreading crown like an open umbrella. With its widespread branches it is ideal as a quick-growing shade tree for a lawn or patio, where in just a few years it will give a circle of shade big enough for outdoor dining. In time it will exceed 20 feet in height and spread, sometimes reaching 50 feet, but typically staying quite a bit smaller. It can be grown either as a tree with a single trunk, or as a multi-stem tree. You can make this choice once it is established, and then prune it to give you the look you want. As a multi-stem tree it grows into a broad vase-shape, and it is wonderful for background planting, in semi-natural areas, and for planting in sunny, dry places. It is also a good choice for a tree in a large pot, where it will quickly produce a lovely mature look.
The bark of the stems is smooth and greenish-gray when young, turning darker gray-brown and developing long vertical stripes of lighter brown in older wood. The foliage is extraordinary beautiful and interesting. Each leaf is 10 to 20 inches long, and 5 to 10 inches wide, with a green central stem carrying 4 to 6 shorter stems along each side. Those stems in turn carries 20 to 30 leaflets, ¼ inch long, along each side, giving the leaf a ferny, very divided look. Remarkably, the leaflets can move, and every night this plant ‘goes to sleep’, with the leaflets folding up and hanging down. No wonder Persians call it shabkhosb which means ‘night sleeper’, and the Japanese call it nemunoki, the ‘sleeping tree’. The leaflets will also fold during rain, and when the leaves are shaken, so when you receive your tree it will probably be sleeping inside the box. The leaves are a rich mid-green, and they give the Mimosa Silk Tree a beautiful airy look.
The Mimosa Silk Tree is in bloom for weeks and weeks, from June or July onwards, looking wonderful and very exotic. Along the branches, at the end of each growing tip, clusters of many strange flowers appear. The petals are very small, and hardly visible. Instead it is the stamens – the pollen-bearing parts of the flower – that are long and showy. There are hundreds of them, each one bright pink, with a tiny yellow tip of pollen. The look is like the crest of an exotic bird, and a tree in bloom is glorious. The blooms give out an exotic sweet fragrance, and bees, butterflies and hummingbirds all love to visit them. When the flowers finally end, they are replaced by 7-inch seed pods, looking like flattened bean pods, which turn from green to brown and last well into the winter, long after the leaves have fallen.
The Mimosa Silk Tree grows best in areas with hot summers, and it is tolerant of both humidity and dry heat. It is very drought resistant once established, although for rapid growth regular deep watering is recommended if it is planted in a very dry location. Any well-drained soil will suit it, from sand to clay and from very alkaline to acidic. This easy tree grows almost anywhere. It has no pests, and deer leave it alone. Avoid wet areas, as this can lead to a disease called wilt, so always plant in a drier part of your garden. It is hardy in zone 6, and really thrives in zones 8 and 9. In areas with cooler summers the tips of the new branches may not ripen fully before winter comes, so some trimming may be needed in spring to remove dead tips, especially on younger trees that are growing very vigorously.
The Mimosa Silk Tree is also called the Persian Silk Tree or the Nemu Tree. It is not a ‘mimosa’, which is an Acacia tree, and it is called by botanists Albizia julibrissin. It is a unique species in the large Pea family, growing wild in Iran, and westward all the way to Japan, although it now grows naturally in many countries. It was introduced into Europe long ago, in 1749, by the Italian naturalist Filippo degli Albizzia, who it is named after.
