Yellow Dots is a tropical perennial, with deepley lobed fleshy leaves, growing up to 10 inch tall, spreading like a mat; it makes a dense cover. It blossoms profusely; the flowers are orange - yellow. Sphagneticola trilobata has a very wide ecological tolerance range, and seems to be equally suited to dry and moist sites. Although it seems to prefer and do best in sunny sites, it survives very well in shady sites. It grows well on almost all soil types, including bare limestone and nutrient poor sandy beaches and swampy or waterlogged soils. It is tolerant to inundation and high levels of salinity. Plant in frost free areas, will be killed by frost but root hardy & comes back in the spring. Quick Notes: Height: Height about 18 inches. Spreading about 3 feet. Forms roots where stems touch soil.
