Adenophora triphylla
Also called Three Leaf Ladybell, Whorled Leaf Ladybell
Adenophora triphylla is a hardy perennial bellflower from East Asia, grown for its spikes of blue-violet bell flowers. It is one of about 62 Adenophora species, so this entry describes this single species rather than the whole genus.
Adenophora triphylla, also known as Japanese lady bell, is one of the 62 species of Adenophora. It is a flowering plant in the family Campanulaceae that is distributed mainly over the Korean Peninsula, Japan, and China.
Adenophora triphylla grows well in a warm and sunny or slightly shaded niche, but cannot grow in full shade; A. triphylla needs alkaline soil that is slightly moisturized, or peaty soil. Plants are hardy to about −20 °C (−4 °F). Slugs have been known to destroy its young growth or even mature plants.
Adenophora triphylla is an erect, perennial herb growing to 100 centimetres (39 in) in height. It has a white and thickened taproot, shaped like a carrot, 7–16 centimetres (2.8–6.3 in) by 1.5–1.8 centimetres (0.59–0.71 in) in diameter. Stems are white pilose with alternately arranged leaves. It has oval, almost round, serrated leaves growing to 10 centimetres (3.9 in) that are white, sharply pointed, and pilose. A. triphylla flowers are about 13–22 millimetres (0.51–0.87 in) long and have both male and female organs (hermaphrodite), each having 5 stamens and a pistil (the long head of the pistil overhangs the flower). Flowers are pollinated by insects. Seeds are yellow-brown colored and oblong slightly compressed, 1–1.5 millimetres (0.039–0.059 in).
