Jacob's ladder (Polemonium) was given its common name because the arrangement of its leaves is somewhat ladder-like. However, it's Jacob's ladders' flowers that are the real attraction. Polemonium caeruleum and its cultivars send up clusters of flowers atop long stems in late spring to early summer. The bright blue varieties are among the most popular, blooming in clear tones of blue and bluish-purple, offset by yellow centres.....Jacob's ladder is a hardy perennial plant. It is upright and clump-forming, but it will spread by seed. Most Jacob's ladder plants have bell-shaped flowers in shades of purple and lavender, but there are also white, pink, and yellow varieties available. The compound leaves are composed of rows of narrow, pinnate leaflets. The branches grow from a basal rosette and arch and sway as they grow tall.
