Pretty Petals Bloom for Months, Up North or Down South
Lighthearted blooms aren’t the only unique part of the Cold Hardy Mimosa Tree – this gorgeous backyard staple can withstand freezing temperatures down to -10 degrees, making it the hardiest Mimosa variety available. This durable tree thrives under heavy layers of ice and snow with no trouble, so it’s highly adaptable and blooms beautifully, even up North.
The Cold Hardy Mimosa Tree offers a one-of-a-kind, super exotic look to neighborhoods all over the country, with lush green leaves that pop against smooth gray trunks for contrasting appeal.
Their canopies flourish around mid-June, flanked by hundreds of pink blossoms that last until September. The fresh flowers’ multiple long stamens give mimosa trees their nickname, the ‘Silk Tree’, because their silken, luxuriant finish confers timeless beauty that’s ultra-lush.
Attracting an array of wildlife, the Cold Hardy Mimosa Tree is rendered even more graceful by the flutter of hummingbirds and butterflies that surround the tree for a quintessential springtime look that endures nearly year-round. The tough, durable Mimosa cultivar is extremely drought tolerant and heat resistant, so it will grow in the hottest areas of the South and continue to bloom during long, dry summer days.
And because the Cold Hardy Mimosa Tree reaches a maximum height of 20-35 feet and width of 20-25 feet, it’s well-suited to any landscape, even those with limited space. Their voluminous, thick canopies impart relaxing shade for hot summer days or breezy springtime nights.
Planting the Cold Hardy Mimosa means up to four months of blooms and a tree that survives everything, from poor soil to various climate conditions. Elevate your landscape with this expressive tree!

My new tree
I ordered the 2-3 ft. And it came right around there. It looked pretty healthy. Got it in the ground a couple days later. So far so good. Can't wait to see it in a year.
Arrived in good shape
Temperatures in the high 80's and low 90's did not appear to harm them in transit. Pleased. Will order here again.
Came as a stick now 8 ft tall in 4 months
Came as a stick.. now 8 ft tall. This tree was literally a stick when it arrived. It has been in the ground about four months and is easily over 8 feet. It's branches are full and lush.
Good Healthy tree
Came with no leaves but was green. 2 months later green and growing leaves and healthy as ever! Hoping it makes it through our tough winters zone 5.
Planting & Care
The Cold Hardy Mimosa tree (Albizia julibrissin "EH Wilson") is a decorative, cold hardy, full sun loving tree that will bring you 3-4 months of beautiful delicate blooms. Also known as a “silk tree,” the mimosa is commonly grown in USDA growing zones 5-10. Once established, the tree can take cold snaps as low as -10 degrees! The tree is considered a rapid grower, maturing to heights of 30-40 feet tall and 20-25 feet wide so be sure to take into account the necessary space needed for the tree’s mature stature. The tree is quite adaptable to different soil types providing the drainage is good and is fairly drought tolerant. The delicate blooms will bring forth a wide array of nature such as hummingbirds, butterflies and bees for pollination.
1) Your location should have well draining soil and receive full sunlight.
2) Dig your hole twice as wide as the root ball and just as deep. This will allow the roots to spread through the loosened soil in the early stages.
3) Mix in peat moss with the soil removed from the hole with ratio of one part peat moss to four parts soil. Sphagnum peat moss will aid in the fertility and drainage of the soil.
4) Insert the tree into the planting hole and gently spread the roots by combing them with your hands.
5) Gradually back-fill your hole with the amended soil and gently firm the soil down with a shovel. Make sure not to pile higher than the soil level, or crown, where the tree's roots meet the trunk.
6) Water your planting site deeply with a slow trickling hose. You'll want to water enough in order to saturate down to about an inch below the soil.
Watering: It's very important that you water your mimosa tree sparingly. The need for watering should only be during excessive dry spells. The peat moss soil mixture will assist with drainage since the tree will not do well with excess water. A steady flow of water from a hose for about 10-15 minutes once every two weeks should be enough. Anything more than that results in diseases related to over watering, like root rot.
Fertilizing: When fertilizing your mimosa tree select an all-natural, organic, slow-release tree fertilizer. Fertilize in the early part of the spring growing season when it's not too hot or cold. Check your forecast to be sure no heavy rainfall will occur within a couple of days of applying the fertilizer. Excessive rain could wash away a lot of the slow-releasing fertilizer. Apply to the soil according to the package instructions. Slow-release is granular or pelletized and can be sprinkled around the planting site. Water will gradually soak the nutrients into the soil where your mimosa tree will absorb them over time. Other forms of slow-release fertilizers can be in the form of stakes that insert into the ground near the tree or in a liquid form that can be applied using a sprayer. Water after applying your fertilizer to prevent salt build up, which can burn the tree.
Pruning: Your mimosa tree will not require very much attention but could benefit from some minor pruning in the fall season. Remove branches growing along the lower trunk area at a 45-degree angle with sterilized pruning shears just beyond the neck collar (where the limb connects to the trunk). Cutting the neck collar can damage the tree. Removing the lower limbs encourages more growth towards the top of the tree. A pole saw is useful for removing dead limbs, for pruning branches out of reach and for forming the shape of your mimosa's canopy. Thinner branches should be cut 3-5 inches from the end of the limb to promote thicker canopy growth.
*Tip: Sterilize your tools after each cut to prevent contamination. Antibacterial soap and/or rubbing alcohol are perfect for cleaning your tools.
Mimosa trees are not only known for their splendid feathery blooms but also for the enchanting smell the blooms produce. "Albizia Calm" is the extract derived from mimosa trees that is known to support mental calmness. A healing salve can also be made from the mimosa tree and it is primarily used in the treatment of skin irritation and burns. The leaves of your mimosa tree can also be collected and used as a tea that soothes mouth soreness. Mimosa trees are very low maintenance, a delight for the senses and a beautiful addition for your landscape.
