Japanese name: ヤマホタルブクロ (山蛍袋)
Scientific name: Campanula punctata var. hondoensis
[Overview]
A perennial 40–80 cm tall, found in mountains.
The stem is covered with coarse hairs.
There are basal leaves and stem leaves; the basal leaves have withered by flowering time.
The basal leaves are ovate-cordate with long leaf stalks.
The stem leaves are simple and alternate, triangular-ovate to lanceolate, with irregular teeth on the margin.
The leaves on the lower part of the stem have leaf stalks, and the stalks are winged.
The flowers are borne at the stem tip and in the leaf axils, and open starting from the upper part of the stem.
The flowers are bell-shaped, 2.5–5 cm long, and hang downward; the color ranges from white to reddish purple.
There are dark spots on the inside of the corolla.
The corolla is divided into 5 lobes at the tip and is densely covered with white hairs on the inside.
The calyx is divided into 5 lobes and is swollen between the lobes; it lacks the reflexed triangular appendages found in Hotaru-bukuro.
The fruit is a capsule.
[Cultivation]
Propagate from seed or by cuttings of shoots.
It prefers a well-drained site in sun to partial shade, out of the afternoon sun.
It is best planted under deciduous trees that give partial shade in summer.
It is vigorous and, if the environment suits it, grows well even when left alone.
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.
Flowering plants need little fertilizer, but potted plants may be given a slow-release chemical fertilizer with equal amounts of the three components, or diluted liquid fertilizer, in spring.
Pests and diseases include slugs, armyworms and aphids.
