The Mimosa Tree is a stunning show of flower bursts, which are often compared to starbursts or fireworks. This small to medium-sized Mimosa Tree grows quickly and has the most beautiful pink flowers in the summer. A lot of butterflies, bees, and hummingbirds will come to these flowers because they have bright, tight clusters of stamens that are pink to yellow at the tips. Frequently known as the “silk tree”, the stamens of the flower are reminiscent of silk threads. Its leaves are called palmate, and they look like small fronds that look like the leaves of palm trees or ferns. Texture is a large aspect of why the Mimosa Tree has gained popularity throughout the United States. Between 20 and 30 small leaflets make up the background that the bright colors of the mimosa flower bloom against.
The Mimosa Tree is known by many other names throughout the world. Its Italian namesake, Filippo degli Albizzi, provides it a portion of its scientific name, Albizia julibrissin. The other part of the name is derived from a Persian word meaning “silk flower”. Commonly found throughout the world’s warmer climates, the Mimosa Tree is a popular ornamental flowering tree. It is also fast-growing, making it an irresistible choice for many homeowners. The 20 to 25-foot-tall Mimosa Tree has the right height, shape, and leaf density for gardeners who want to give smaller plants dappled shade. It is always a beautiful addition to the garden.
These trees can survive in dry conditions and grow quickly. They do have pretty flowers, but their small fruit and leaves can make it necessary to clean up after them. Mimosa trees are very pretty when planted as a focal point in the yard or in a row as a border along gates or fences. They are well worth the work of cleaning up and pruning them. Enjoy the luscious pink blossoms in summer and the gentle shape throughout the year.
Enjoy some quick tips here. For more complete information, read about these hints in more detail below.
Sunlight: Mimosa trees do best in full sun, but in drier areas, a little afternoon shade may be good for the tree.
Soil—The Mimosa Tree does best in acidic, moist soil that drains well, but it can also do well in a wide range of other soil types.
Water: The drought-tolerant Mimosa Tree likes at least an inch of water a week, but it can handle mild to moderate droughts pretty well.
Pruning: After three years of growth, pruning should only be done in the winter when the tree is dormant. Remove dead or diseased wood.
The mimosa tree, also known as silk tree, is a stunning ornamental plant with fluffy pink flowers and fern-like leaves. But when exactly do new leaves emerge on the mimosa? This complete guide will cover everything you need to know about mimosa leaf growth.
An Overview of Mimosa Trees
Native to Asia, the mimosa tree (Albizia julibrissin) is part of the Fabaceae family. It’s a fast-growing deciduous tree that reaches 20-40 feet tall and 15-25 feet wide. The leaves are bipinnately compound, meaning they have rows of leaflets stemming from a central rachis. There can be as many as 20-40 pinnae pairs on each leaf and each pinna contains 10-25 tiny oblong leaflets.
One of the main draws of the mimosa is its puffy pink flowers that emerge in late spring/early summer. The flowers have many thin, silky stamens that give them a soft, fluffy appearance, thus leading to mimosa’s nickname – the silk tree. These flowers attract pollinators like bees, butterflies, and hummingbirds. Once pollinated, they develop into seed pods that persist through winter.
Mimosa trees thrive in full sun and moist, acidic, well-drained soil. They tolerate drought but prefer consistent water. Established trees can handle short dry spells. Avoid soggy soil which leads to root rot. Mimosa trees grow in USDA zones 6-10. Protect young trees from frost damage.
Mimosa trees grow rapidly but live only 20-40 years. They spread aggressively, producing many seed pods. Make sure to pick up fallen seed pods to prevent unwanted spreading.

The Leafing Habits of Mimosa Trees
When it comes to new leaf growth, mimosa trees follow the typical pattern of deciduous trees. They are late-breaking dormancy, meaning they leaf out later in spring Here’s an overview of mimosa tree leaf emergence
-
Dormancy Period: In autumn, mimosa trees enter dormancy and drop their leaves. They remain leafless throughout the winter.
-
Leaf Buds As spring arrives, leaf buds begin to swell and emerge on branches This signals the tree is breaking dormancy
-
New Leaves: New leaves start unfurling from the buds in mid to late spring. This occurs April-May in USDA zones 7-9. Farther north it’s late May-June.
-
Full Foliage: By early summer, the mimosa will be fully leafed out with its fern-like bipinnate leaves. Just in time for the summer flowering show!
Signs Your Mimosa is Growing Leaves
Wondering if your mimosa tree is leafing out properly? Here are the tell-tale signs that new growth is underway:
-
Swollen leaf buds on branches: If plump buds are bulging from branches, your mimosa is breaking dormancy. Leaves will unfold shortly.
-
Green leaf tips emerging: The first glimpse you’ll get of new leaves are the tips poking out from buds. Once green is visible, leaves will quickly unfurl.
-
Expanding green leaves: Over the course of several weeks, the small new leaves will rapidly grow to full size.
-
Rows of leaflets forming: As leaves expand, you’ll see the bipinnate form taking shape. The rachis extends with rows of pinnae branching off, each divided into many tiny oblong leaflets.
-
Thickening foliage: Finally, as more leaves fill in, the mimosa will transition into a full head of soft, ferny foliage.
If it’s well into spring but your mimosa shows no signs of leaf growth, it could indicate a health problem.
Problems With Mimosa Tree Leaf Growth
While lack of leaves is normal during the winter dormancy period, if your mimosa fails to leaf out in spring it likely indicates an underlying issue. Here are some potential causes:
-
Winter damage: If temperatures plummeted well below freezing, the cold could have damaged shoots and buds, preventing leaf growth.
-
Pests/diseases: Fungal diseases like verticillium wilt and pests like webworms can impair the mimosa’s ability to leaf out. Inspect for signs of infection.
-
Root damage: Compacted soil, damaged roots from construction, or girdling roots can restrict nutrient uptake needed for new leaves.
-
Improper pruning: Pruning mimosa at the wrong time (late winter) could inadvertently remove developing leaf buds.
-
Transplant stress: Newly transplanted trees may fail to leaf out while adjusting to their new site. Give them time.
-
Harsh conditions: Insufficient water, overly wet/dry soil, or windy exposure could overly stress the tree.
If your mimosa shows no new growth by early summer, and you’ve ruled out the causes above, the tree may be dying. Have an arborist inspect and see if anything can be done to revive it. But prepare for the worst – mimosas are short-lived trees and may need replacing.
Caring for New Mimosa Tree Leaves
Once your mimosa begins leafing out, proper care will keep the foliage looking lush:
-
Water regularly: Give your mimosa tree at least 1-2 inches of water per week as leaves are emerging and expanding. This will ensure adequate moisture.
-
Apply mulch: A 2-4 inch layer of shredded bark or compost around the base preserves soil moisture and temperature.
-
Fertilize lightly: Use a balanced organic fertilizer to provide nutrients. But avoid over-fertilizing, which causes excessive leaf growth at the expense of flowers.
-
Prune selectively: Prune only as needed to maintain shape/vigor. Avoid heavy pruning which removes developing buds.
-
Monitor for pests: Be on the lookout for spider mites, webworms, or other pests that can attack new foliage. Apply organic methods to control.
With the right growing conditions and care, your mimosa tree will produce an abundance of feathery green leaves starting each spring. The burst of foliage signals the prelude to the fabulous silk-like blooms soon to come!

The Mimosa Tree is a small to medium sized ornamental tree. It is also exceptionally fast-growing. The tree will quickly grow to be 20 to 25 feet tall and 10 to 20 feet wide. This tree grows very quickly. In a growing season, the Mimosa Tree can often gain up to 5 feet!
The Best Places to Plant the Mimosa Tree
The Mimosa Tree, which originated in southwestern and eastern Asia, prefers the warmer climates. The tree is now commonly found throughout many regions of the world, and it can withstand brief cold spells.
The Mimosa Tree grows best in USDA Hardiness Zones 6 through 10 in the United States. It likes the subtropical to tropical climates of many lower latitudes. Plant the mimosa tree where it will get full sun. However, some partial shade can help the tree keep its water, especially in the driest parts of the southwest. The Mimosa Tree is best suited as an accent plant, where its ornamental beauty will not be lost. For many gardeners, this may mean a center-garden or center-yard spot. The Mimosa Tree can also be used to line driveways or entryways, and because of its uniform shape, it looks good with other trees of the same species.
Mimosa Trees prefer the moist, well-drained soil typical of loam. With regard to pH, the tree enjoys slightly acidic soil. Despite these preferences, the Mimosa Tree readily adapts to various soil conditions. Water is not as much of a concern for the Mimosa Tree. In fact, short dry spells will not harm this tree since it is drought-resistant. The Mimosa, like most flowering trees, needs at least an inch of water a week, which can come from rain or irrigation. If the area where the tree is planted is prone to severe droughts, you might want to buy an irrigation system that will help you control the flow of water and get it to the Mimosa during those really hot, long-lasting droughts.
The Mimosa Tree is a beautiful ornamental plant. When considering planting locations, look for one where its beauty will shimmer!.
