Jacob's Ladder gets its name from the arrangement of its leaves – pairs of opposite leaflets resembling a ladder. In early summer, erect stems rise up from the bright green foliage carrying clusters of bell-shaped flowers. A cottage-garden favourite, Jacob's Ladder is happiest in partial shade, and looks equally at home in a wildlife garden setting or in grass. Although it is short-lived, it self seeds freely.  Growth The plant usually reaches a height from 45 to 60 centimetres (18 to 24 inches), but some occasionally will be taller than 90 centimetres (35 inches.) The spread of the plant is also 45 to 60 centimetres. Habitat The plant is native to damp grasslands,woodlands,meadows rocky areas in temperate of Europe and Asia. Cultivation 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. Cultivated varieties include 'Blue Pearl' White-flowered ('Album', 'White Pearl') and a variegated ('Snow and Sapphires') varieties are available. The plant does not have serious insect or disease problems. Leaf spotpowdery mildewbe problems, particularly in humid climates. The foliage may scorch if the plant gets too much sunlight. The leaflet will brown up if soils are allowed to dry out so keeping an eye on the leaflet tips is a good way to gauge water levels. The foliage will generally decline and become less attractive as the summer progresses. It is important to keep an eye out for slugs.
