General Information

Night-flowering catchfly plants can produce up to 2500 seeds per plant. Not fully matured seed can germinate similarly to mature seed shed from the capsule (McNeill 1980Footnote 4). The small seed size makes it difficult to clean out of clovers such as Alsike clover. Contaminated seed is the main method of spread for this species (McNeill 1980Footnote 4).
