Hardy Orange

A hardy orange? Really, in my Midwest garden? Yes! This relative of the citrus plant is a favorite of collectors, and can most often be found in public gardens and arboreta. Now it can star in your garden. It's technically a large shrub but is often pruned as a small tree, performing best in sunny, well-drained locations. A classic hedgerow plant, Hardy Orange is virtually impenetrable due to its formidable green thorns, so plant where traffic is minimal. But be sure to pick a spot where the intensely fragrant, orange blossom-like white flowers can be enjoyed in the spring. The fruits (which are not edible) ripen to an attractive yellow in the fall and never fail to elicit comments. An especially effective accent or specimen shrub, it is an interesting and unusual plant, certain to turn heads. Poncirus trifoliata

  • Unique CharactersticsMissouri Botanical Garden: Poncirus trifoliata, commonly called hardy orange, a citrus relative, is a thorny, well-branched, deciduous shrub or small tree which typically grow 8-15' (less frequently to 20') tall. Three-lobed (trifoliate as per the species name) leaves emerge yellowish-green in spring, turn glossy dark green in summer and fade to yellow in autumn. Spiny, dark green stems. Fragrant, white, 4-7 petaled flowers (to 2" diameter) appear singly in spring. Flowers give way to 1-2.5" diameter fruits (miniature downy hardy oranges) which ripen to an attractive yellow in the fall. Fruits of this citrus relative are edible (lemony flavor), but are very acidic and seedy. Fruits can used to make marmalade (use peel zest and pulp), but are usually left on the tree where they persist well into winter and often provide significant ornamental interest.
