Mexican Buckeye Tree ( Ungnadia speciosa )

Mexican Buckeye trees are great native Texas (and Southwest portions of North America) pollinator-supporting trees.   These trees are early-blooming, with a soft pink bloom and is a nectar and pollen source for the bees, butterflies, moths, and more.

While they are not in the true buckeye family – their seed pods look similar.   The Mexican Buckeye trees are actually in the Soapberry family

While the trees are young – they’ll likely need watering – especially until they are established.

These trees are all planted from seed in January 2026 that was wild-foraged in North Texas.   Grown in tall tree-pots – (4″x4″ x 10″ tall) – these first year saplings range from about 12″ to 18″ tall on average.

Sapling Planting Information:

When and Where to Plant

  • Timing:  Plant between November 1 and April 1 while the tree is dormant.
  • Sunlight: Choose a spot that gets at least 6 hours of direct sunlight daily, though it tolerates partial shade.
  • Soil: Select fast-draining sandy, loamy, or rocky soil. If you have heavy clay, amend it with compost to improve drainage and prevent root rot.

Step-by-Step Planting Instructions

  • Dig the hole: Dig a hole twice as wide as the sapling’s root ball and just as deep
  • Prepare the plant: Gently remove the sapling from its container and lightly tease or loosen the outer roots to encourage outward growth
  • Position the sapling: Place the plant in the center of the hole. Ensure the top of the root ball sits level with or slightly above the surrounding ground level
  • Fill and water: Backfill the hole with the native soil (or your amended mix), tamping down gently, and water thoroughly to settle the soil and eliminate air pockets
  • Mulch: Add a layer of mulch around the base to retain moisture, keeping it a few inches away from the actual trunk.

Subsequent Care

  • Watering: Water deeply during the initial establishment phase, then reduce frequency. Once established, it is highly drought-tolerant and typically only needs watering a few times a year
  • Fertilizing: No heavy fertilizer is required; an annual application of compost is plenty
