Pollination Info for Jacob's Ladder (Polemonium reptans)

Jacob's Ladder (Polemonium reptans) is pollinated by bees, butterflies, and moths. The flowers have both male and female parts, making them self-fertile. However, cross-pollination is more common and leads to greater genetic diversity in the plant population.

Bees are the most common pollinators for Jacob's Ladder. They are attracted to the blue or purple flowers and collect nectar and pollen. As they move from flower to flower, they transfer pollen from the male parts (anthers) to the female parts (stigma) of the flowers.

Butterflies and moths also visit Jacob's Ladder flowers for nectar. They are less efficient pollinators than bees, as they do not deliberately collect pollen, and may visit fewer flowers during each visit.

Pollination is essential for seed production in Jacob's Ladder. Without pollination, the flowers will not develop into seed pods, and the plant will not be able to reproduce.
