Polemonium caeruleum, known as Jacob's-ladder or Greek valerian, is a hardy perennial flowering plant. The plant produces cup-shaped, lavender-coloured or white flowers. It is native to temperate regions of Europe.
The plant usually reaches a height from 45 to 60 centimeters (18 to 24 inches), but some occasionally will be taller than 90 centimeters (35 inches.) The spread of the plant is also 45 to 60 centimeters. It can grow in North American hardiness zone 2.
The plant is native to damp grasslands, woodlands, meadows and rocky areas in temperate areas of Europe.
The plant normally prefers soil that is rich in moisture and lime and does not require as much sunlight as other plants. Depending on the conditions, it will need varying amounts of water in the summer. If it is hot summer, the plant may require extra water. If it is an average summer, it probably won't need extra water. Normally hardy, some varieties (e.g. 'Blue Pearl') behave as tender biennials, which means they are effectively annuals in cooler climates (below hardiness zone 6).
Cultivated varieties include 'Blue Pearl' and 'Brise d'Anjou'. White-flowered ('Album', 'White Pearl') and a variegated ('Snow and Sapphires') varieties are available.
(Cats are attracted to the scent of the plant, particularly younger plants. A person who is growing Greek valerian in a container or home garden should protect the plants if they own a cat.)
The plant was first used as a medicinal herb in ancient Greece. The ancient Greeks used the root to treat dysentery, toothaches and animal bites. The plant was also found in a few European pharmacies during the nineteenth century and was used as an antisyphilitic agent and to treat rabies. Today, the plant is not usually used medically.
Polemonium caeruleum was voted the County Flower of Derbyshire in 2002 following a poll by the wild plant conservation charity Plantlife.
Today, the plant is usually used in potpourris and is boiled in olive oil to make black dyes and hair dressing, but it has few other significant uses.
Bees work the flowers for both pollen and nectar. Flowers of other species of Polemonium are also useful honey bee forage.
