Round-leaved sundew reproduces vegetatively or by seed [8,29,37,52].
Vegetative reproduction takes place when leaf buds form plantlets, or
when axillary buds below the rosette form a secondary rosette. As the
stem decays, the two separate [8,37]. Adventitious plants develop in
the autumn. They occur occasionally in the field but are often present
in greenhouse experiments, possible due to a high level of humidity
When flowers are open during the day, they are cross-pollinated by wind
or insects. Self-pollination may take place as flowers close in the
evening [45,50]. The fruits often persist unopened, and seeds are
released when the fruit rots . The fusiform seeds are 0.06 to 0.07
inch (1.5-1.8 mm) long and 0.008 inch (0.2 mm) wide and have an inflated
testa. Air trapped in the testa makes the seed buoyant and capable of
floating for days on water surfaces. Seeds may be carried some distance
with snowmelt and flooding . Plants flower in their first summer
and every year thereafter .
