'Paradigm' is a hosta that has lots of appeal throughout the spring and summer. Young leaves have chartreuse centers with light green edges that seem to capture the morning sunlight in spring. Later in summer, the leaves mature to golden yellow centers with blue-green edges that simply glow in the late evening sun. Hostas need dappled shade and will burn in dry or sunny environments. They need plenty of nitrogen to form vigorous leafy growth, but will thrive in most soils, including clay, as long as they plants are well irrigated. Hardy zones 3-9.
