Water Clover is also known as Marsilea macropada and is part of the family, Marileaceae.
It looks like a four leaf clover but is actually closely related to ferns.
The water clover is a rare, Texas native and doesn't have to stay in water but doesn't like to dry out so its great for areas that stay wet.
It does best in the sun but tolerates partial sun.
The water clover is tolerant of shallow, poorly drained and alkaline soils.
It's evergreen most of the time but may occasionally need to be cut back, especially after a hard winter.
The clover spreads quickly and can be propagated by pulling apart pieces and planting.
