Citrus consists mainly of evergreen shrubs and trees, which are often armed with spines. They feature simple, leathery leaves that release a pleasing fragrance, typically borne on winged petioles. The plants produce aromatic flowers that are usually white or have a hint of pink, which are succeeded by sizable, juicy fruits.

Citrus australasica, commonly known as finger lime, is a spiny, evergreen subshrub that can reach heights of up to 3 meters. Its leaves are ovate, measuring up to 4 centimeters in length, and it produces small, white flowers about 1 centimeter wide in the spring and summer seasons. The cylindrical fruits can grow as long as 7 centimeters, exhibiting a green color with a bronze flush, maturing in late autumn. To enjoy the juicy 'pearls' inside, slice the fruit in half and gently squeeze. For optimal growth, finger limes thrive in a cool or temperate greenhouse or conservatory and should be relocated outdoors during the warmer summer months.

Citrus limetta 'Romnya' (F)

Citrus limetta is an evergreen tree that can reach a height of up to 8 meters, though it typically grows shorter in cultivated settings. Its leaves are glossy and range from mid- to dark green. The tree can produce fragrant white flowers throughout the year under ideal conditions, with the primary bloom occurring in spring. These flowers give way to oval-shaped green fruits that resemble limes but mature to a yellow hue. The flesh of these fruits has a lower acidity, resulting in a sweeter and milder taste compared to traditional limes, which is reflected in one of its common names, the sweet lime.
