Super-Fast Growing Tree with Show Stopping Spring Flowers

If you are looking for a tree to grow in that spot in your yard where absolutely nothing else will grow, then Purple Robe Locust, Robinia pseudoacacia 'Purple Robe', is the tree for you. A prime form of the ever-popular black locust family of trees, Purple Robe Locust will grow just about anywhere you plant it.

These fast growers thrive in tough spots, making themselves at home in even barren or sandy lots.

It doesn’t take the young trees very long to reach their full height of 30-40 feet. If time to maturity is an issue, then Purple Robe is the answer.

Each spring the canopy of the tree is covered in interesting and delicate looking bronze-red leaves. Then in late spring hundreds of wisteria-like purple flowers appear, filling the air with a heavenly scent.

Purple Robe Locust trees can be clipped to stay smaller in your border, if you’d like. They make great street trees, too, handling the tough conditions by your road with ease.

Purple Robe Locust trees populate by suckers, which are easy to pull out if you don’t want them. If you do like the idea of a natural look, then these trees are happy to oblige, filling in the space around them with more beautiful trees.

SO, don’t despair over that section of your yard where even the grass doesn’t grow that well. Robinia Purple Robe is happy to help you out! Buy yours from today.
