Koelreuteria paniculata nana (Dwarf Golden Rain Tree)

Koelreuteria paniculata nana (Dwarf Golden Rain Tree) is a cultivar of the Koelreuteria paniculata (Golden Rain Tree). It is a smaller, compact version of the original species. Here is some information about the Dwarf Golden Rain Tree:

Size and Growth Habit: The Dwarf Golden Rain Tree is known for its smaller size compared to the standard Golden Rain Tree. It typically reaches a height of around 6 to 10 feet (1.8 to 3 meters) with a similar spread. Its compact growth habit makes it suitable for smaller gardens, urban spaces, and container planting.

Leaves: The leaves of the Dwarf Golden Rain Tree are similar to the standard species. They are pinnately compound with 7 to 15 leaflets arranged along a central stem. The leaflets are oval or elliptical in shape and have serrated edges. The foliage is green and turns yellow in the fall, adding to its ornamental appeal.

Flowers: Like the standard Golden Rain Tree, the Dwarf Golden Rain Tree produces clusters of bright yellow flowers. The blossoms are small and have four petals. They form panicles that are 8 to 14 inches (20 to 35 centimeters) long. The flowers appear in late spring or early summer, typically around June, and attract pollinators such as bees and butterflies.

Fruit: After flowering, the tree develops papery, bladder-like capsules similar to the standard species. These capsules contain seeds and resemble small Chinese lanterns. They persist on the tree throughout the winter, providing visual interest.

Cultural Significance and Uses: The Dwarf Golden Rain Tree is valued for its compact size and ornamental qualities. It is often planted as an accent tree, in small gardens, or as a specimen plant. Its smaller stature makes it more manageable for limited spaces while still offering the beauty of the Golden Rain Tree's yellow flowers and interesting seed capsules.

When cultivating the Dwarf Golden Rain Tree, it is generally advisable to provide it with full sun to partial shade and well-drained soil. Regular watering is beneficial during the establishment phase, but once established, it can tolerate some drought. Pruning can be done to maintain its compact shape.
