Suitability as Green Roof plants
rotundifolia plants are valuable in
plantings that are going to get the very minimum
or no water in winter as well in combinations with other plants that do
not have a
very vigorous nature. Green roofs with shallow low nutrient
soils provide an ideal growing environment for these very attractive
