Scientific name: Campanula glomerata

[Overview]
A perennial 0.2–1.3 m tall.
It prefers calcareous soil.
The stem is erect and covered with short soft hairs.
There are basal leaves and stem leaves; the basal leaves are 6–15 cm long and 2–7 cm wide, ovate-lanceolate to ovate, with a leaf stalk, and have usually withered by flowering time.
The stem leaves are simple and alternate, 4–10 cm long and 0.7–4 cm wide, oblong to ovate-lanceolate; the lower leaves have a leaf stalk and the upper leaves are stalkless.
The leaf margins are toothed.
The flowers are borne 15–20 in a raceme at the stem tip or in the axils of the upper leaves, are enclosed by involucral bracts, and face upward.
The flowers are funnel-shaped, about 1.5–2.5 cm long, with the tip divided into 5 lobes, and are purple to bluish purple, or blue, rarely white.
The fruit is a capsule.

[Cultivation]
Propagate from seed or by division.
It dislikes heat and humidity.
It prefers a well-drained site in sun to partial shade, out of the afternoon sun.
When planted in the ground, it is best planted under deciduous trees.
For potted plants, water thoroughly when the soil surface dries; for plants in the ground, rainfall is sufficient unless sunny weather continues and the soil becomes severely dry.
Fertilize sparingly; apart from basal fertilizer, give diluted liquid fertilizer in spring and autumn.
Pests and diseases include slugs, armyworms, spider mites and aphids.
