Plant Profile: Citrus trifoliata

The Trifoliate Orange, also known as Hardy Orange, is a deciduous shrub or small tree characterized by its thorny branches. It thrives in sunny spots with well-drained, acidic soil and can reach heights of nearly 20 feet. This plant typically flowers in mid-spring, with its fruit maturing in early fall. Due to its sharp and abundant spines, it is not suitable for areas with heavy foot traffic. However, it can be shaped into a dense, impenetrable hedge and serves as an attractive winter specimen. Preferring full sun and well-drained, acidic conditions, it is not tolerant of shade, is easy to transplant, and is generally free from significant pest or disease issues.

The fruit, resembling lemons, is extremely sour and contains many seeds. Consuming it in large amounts can lead to severe stomach discomfort and nausea due to its high acidity. Additionally, some individuals may experience mild skin irritation from prolonged contact. While the peel and pulp can be utilized for making marmalade, the fruit is often left on the tree for its aesthetic appeal throughout the winter months.

This plant makes for an excellent hedge, as its thorns effectively deter intruders, although it has the potential to become somewhat invasive.
