Pinguicula primuliflora Flowering and Seed Production

A grower asks if the primrose butterwort (Pinguicula primuliflora) produces seeds and whether to remove the flower.

Seed Production

P. primuliflora produces seeds only when cross-pollinated. In greenhouses, butterflies and moths often pollinate them, leading to seed pods.

To Cut or Not to Cut

Removing the flower may conserve energy, but the flowers are attractive and a selling point. Unlike Venus flytraps, butterwort flowers are ornamental. The choice depends on whether you prioritize seed production or plant vigor.
