Growing & Maintenance Tips:

The preference is wet to moist soil and partial sun. Full sun is tolerated if the soil is consistently moist, and light shade is also acceptable. The soil should be fertile and loamy. This plant withstands occasional flooding, but becomes muddy and ragged-looking if it receives too much abuse. The small seeds require light to germinate.
