Acacia dealbata 'Gaulois Astier', commonly known as Mimosa Tree, is an evergreen shrub or a small ornamental tree with a pale green trunk, and large, silvery-grey, feathery or fern-like foliage. Its attractive and unique foliage is popular for its tropical looks and light-filtering effect. In late winter and early spring, Acacia dealbata produces sweetly fragrant, ball-shaped, spectacular, bright yellow fluffy flowers. It is well known and loved for these vibrant yellow flowers that gloriously announce the coming of spring. It likes neutral or acidic, well-drained soil, and sheltered position in full sun. It can grow up to 6m and is suitable for any frost-free location if its height isn’t a problem. Since it is not very sturdy, it may need winter protection. Generally disease-free, but not pest-free. It can get glasshouse red spider mite, fluted scale, and mealybugs. After flowering, it needs a little bit of pruning for removal of dead and damaged branches.

About Us

During this time, we have developed a large stock of trees, mature evergreen shrubs, conifers, Japanese maples, cedars and olives. What sets us apart from a generic garden center is solid unwavering focus on trees and some bigger shrubs. You will find thousands of trees, hundreds of varieties and lots of experts who are working on the nursery and more than willing to help you to choose a plant for you.

What you will not find is hot tubs, garden furniture and plastic garden gnomes. In a nutshell, trees is what we know and trees is what we do, and only trees (and some shrubs to go with the trees).
