Gleditsia triacanthos var. inermis 'Honeybee'
treeHoneybee Locust is a thornless cultivar of the Black Locust, a deciduous tree prized for its delicate, fern-like foliage and fragrant, pale yellow flowers that attract pollinators. This cultivar combines the ornamental beauty of the species with improved garden utility through its lack of thorns. It's a medium-sized tree that provides dappled shade and nitrogen fixation benefits to surrounding soil.

Seedling/Young Tree
1-2 yearsSmall sapling with emerging compound leaflets, delicate branching structure
Water regularly; mulch around base to retain moisture and suppress weeds; stake if necessary for support; protect from harsh winds
Establishment
3-5 yearsTree develops stronger branching framework; fern-like pinnate leaves unfold; trunk thickens
Continue regular watering; prune to shape and remove competing leaders; monitor for pests; apply balanced fertilizer sparingly
Flowering
2-4 weeksTree produces fragrant, drooping clusters of small, pale yellow to cream flowers; flowers appear in late spring (May-June)
Do not prune during flowering; allow bees and other pollinators access; flowers may cause mild allergies in sensitive individuals
Fruiting
4-6 monthsAfter flowering, flat, elongated seed pods (legumes) develop; pods are greenish initially, turning brown at maturity in fall
Pods may be messy but benefit wildlife; seed pods can be left for natural propagation or removed if desired; no pruning needed
Mature Tree
Ongoing (50+ years)Full-sized tree, 30-50 feet tall with spreading canopy; compound leaves provide dappled shade; minimal maintenance needed
Prune only to remove dead, diseased, or crossing branches; tree is nitrogen-fixing and improves soil; very drought and pest resistant when mature

Common Pests
-
Prune and remove infested branches; maintain tree vigor with appropriate watering and care; yellow or white paint on trunk in early summer may deter adults; chemical controls rarely necessary for established trees
-
Hand-pick and remove webbed branches; prune affected areas; encourage natural predators; rarely requires chemical intervention on mature trees
-
Strong water spray to dislodge; hand-pick if populations are low; encourage parasitic wasps; rarely causes significant damage
Uses
Pollinator and Nectar Source
WildlifeThe fragrant, abundant flowers are highly attractive to honeybees, native bees, and other pollinators, making it an excellent landscape tree for supporting pollinator populations. The flowers provide early-season forage when food sources may be limited. [source]
Ornamental Shade Tree
HouseholdThe delicate, fern-like compound foliage creates an attractive, open canopy that provides dappled shade while still allowing light to reach plants below. The thornless form makes it safer for residential landscapes. [source]
Nitrogen Fixation and Soil Improvement
HouseholdAs a legume (nitrogen-fixing tree), Honeybee Locust enriches soil with nitrogen through its root nodules, benefiting surrounding plants and reducing fertilizer needs. This makes it valuable for ecological landscaping and sustainable gardens. [source]
Wildlife Habitat and Food Source
WildlifeThe seed pods provide food for wildlife, and the open canopy offers perching and nesting sites for birds. The tree supports insects that feed birds and other wildlife. [source]
Drought-Tolerant Landscape Tree
HouseholdOnce established, Honeybee Locust is extremely drought-tolerant and requires minimal maintenance, making it ideal for water-wise landscaping and low-maintenance gardens in dry regions. [source]
Harvest Tips
Honeybee Locust is a timber and ornamental tree, not harvested for food. Allow seed pods to mature naturally in fall for wildlife benefit or remove them if concerned about self-seeding. Collect seeds in autumn if propagation is desired.
Fun Facts
- 🌱 Honeybee Locust was named for its exceptional appeal to honeybees; a single mature tree can attract hundreds of foraging bees during its blooming period.
- 🌱 The tree's compound leaves fold up at night and during rain (nyctinasty), a behavior shared by many legumes that helps protect delicate leaflets from damage.
- 🌱 The wood of Black Locust varieties is extremely durable and rot-resistant, historically used for fence posts, railroad ties, and shipbuilding—some structures built from locust wood over 200 years ago are still standing.
