Ladder to Heaven (Polemonium)
If you want a garden that's buzzing and humming with butterflies, Jacob's ladder, also known as Jacob's ladder, is a must-have in your perennial border. This hardy perennial belongs to the genus of sedgeworts. It thrives particularly well in cottage gardens, along pond edges, and in natural gardens.

Growth form
The upright, herbaceous, clump-forming ladder reaches a height of up to 90 cm. It has lanceolate, feathery leaves (up to 40 cm) that become increasingly smaller toward the flower tip.
blossom
The perennial's flowering period is limited to the period from late May to July. The pale blue flowers (approx. 1–2.5 cm) with their striking yellow stamens are arranged in panicles. Through breeding and hybridization of the ladder to heaven, white and pink varieties are now also available.
Location requirements
Ladders to Heaven prefer nutrient-rich, not too dry, and well-drained soil in sunny to partially shaded locations. Four to six plants are needed per square meter.
Care
Ladders of Heaven are relatively short-lived, but they self-seed prolifically, leaving their mark on the garden. Early pruning prevents uncontrolled seeding and encourages rebloom. Otherwise, Ladders of Heaven are relatively undemanding in terms of care. Dividing the plant (approximately every 2-3 years) increases its resilience.
