Black Locust Tree Seeds 50 Robinia Pseudoacacia
The Black Locust tree (Robinia pseudoacacia), sometimes referred to as Yellow Locust, is a deciduous species native to the southeastern United States. It typically grows 30 to 50 feet tall and can reach up to 80 feet in optimal conditions, with a narrow, irregular form and a short trunk that bears thorny branches. The bark is deeply furrowed and dark, nearly black in color, which contributes to its name.
Leaves are pinnately compound with 7–19 oval leaflets, dark green in summer and yellow in fall. In late spring, it produces drooping clusters of fragrant white pea‑like flowers that attract bees. The fruit is a flat, smooth legume or pod that matures in the fall and contains 4–8 hard, dark seeds. The tree is adaptable to a variety of soils, including poor, dry soils, and it prefers full sun; it is drought- and pollution-tolerant, making it suitable for urban environments. The wood is hard, strong, and rot-resistant, used for fence posts, furniture, and flooring; its flowers are used in honey production. It tolerates USDA hardiness zones 3–8. Maintenance is relatively low, but it can be affected by pests such as locust borers and leaf miners, and its propensity to suckering can make it invasive in some areas. Its fast growth and nitrogen-fixing capabilities have led to its use in reforestation and reclaiming disturbed lands.

from 62 reviewsWorked like an absolute charm!
These markers were perfect for ones that we were replacing. The quality is great and they seem sturdy. The gold detail stands out and is visible from a distance. Shipping was very fast.
Good solution. The little flies have disappeared. We were sure to mist/moisten the surface of each plant once a day for 4 or 5 days, after the initial application of the nematodes, to keep the little guys mobile and able to get to any remaining eggs. So, go for it!
Plant was well packed and shipment was very fast. Received a very nice fully rooted plant in the pot!
The organic garden soil is doing very well in my garden bed. The company was professional, nice, and accommodating to my needs. They provide many types of things for your landscaping at a reasonable price.
Product was delivered promptly and the quality of the product was very good, as hoped for. I was thrilled to receive the product so quickly! Thank you!
Product is great. Didn't care for having to pay am extra $17 tariff to UPS to get it delivered, but I guess that's not your doing. Thank you Mr. President.
My new babay arrived safely and only lost two little leaves so far. The first one I ordered from different shop arrived with two leaves attached that fell off within ten minutes of unboxing and 22 leaves that had came off during shipping. So glad she arrived looking as beautiful as i was hoping. Also had a surprise red arrow syngonium cutting that’s beautiful. Also customer service was amazing. Will definitely order from them again. Hoghly recommend this shop.
Great flag and it works well on our hangar ceiling. A little worried it wouldn't arrive in time for our event but it did.
Enjoyed putting them together
I think I’m in love! This beauty came delicately packaged. Seemed to have no stress at all from shipping. I live in Miami, I was worried about shipping all the way from California. To my surprise she arrived well taken care of already. I can tell this grower takes pride in caring for these babies. Shipping was fast. I just ordered again same day!
Great service and great product. Delivery was quick. Good communication.
lovely olive jar, attractive to keep on display. And useful too.
Fast delivery . Product exactly matches description. Easy to contact with same day replies. We will use them again.
Great job from growing to shipping
