Citrangequat Thomasville

The Thomasville is an American‑created citrangequat, a complex kumquat hybrid.

The result is a bushy tree, very cold‑hardy.

The fruits are large kumquats (50 g +) that can stay on the tree for more than a year.
They are first yellow and acidic in winter and can be pressed for their juice, close to lemon.
Then they turn orange and become sweet and sugary in spring.
In May and then August, the Thomasville is often covered with both fruit and flowers.

Warning: these fruits have a slow and late maturation and must survive an entire winter on the plant.
However, the small fruits can freeze at -5 °C.
To avoid this and be able to enjoy the fruits, it may be necessary to keep this plant in a pot and place it in shelter for the winter.
The adult size is fairly modest and allows this, but do not place it in a heated area.
The plant must remain dormant throughout the winter. Avoid a regular temperature above 18 °C to prevent triggering vegetative growth.

The tree is moderately vigorous, thornless, and has a disorderly growth habit. It can be pruned green in summer.
