Description
You probably have them in your collection, even if you weren't aware... Yellow-flowering, enormously invasive plant. Comes along a lot as stowaway with other plants.

Habitat
Wet, nutrient-poor, acidic sand and peat soils in open areas, such as swamps, wet savannas, moors and ditches, where it adheres to wet surfaces and grows in periodically wet soil, often near or on wet rocks. Widespread in tropical and subtropical areas and thrives in full sun and humid conditions.
Cultivation
I suspect that this will still grow between pavers as long as it does not dry out. Unstoppable. Under the right conditions, they bloom yellow. If the circumstances are less, they skip flowering and immediately form seed (cleistogamus).
Flowering Period
Year-round, actually.
