Symphytum grandiflorum (dwarf comfrey)

Japanese name: ドワーフコンフリー
Scientific name: Symphytum grandiflorum

Symphytum grandiflorum

[Overview]
A perennial about 50 cm tall.
It has thick roots.
The whole plant is covered with white hairs.
There are basal leaves and stem leaves; the leaves on the stem are simple and alternate, elliptic to ovate.
Cymes arise from the upper part of the stem and bear white to yellowish-white flowers that hang downward.
The corolla is tubular, with shallow 5-lobed tips.

[Cultivation]
Propagate by division.
It prefers sun to partial shade and slightly moist, moisture-retentive soil.
If the environment suits it, it grows well even when left alone.
Even for plants in the ground, in midsummer water in the cooler hours of morning or evening when the soil surface dries, so that it does not become too dry.
Fertilize sparingly; if base fertilizer is applied, no further fertilizing is particularly necessary.
There are no particular pests or diseases.
