Another S. byzantina cultivar, 'Primrose Heron' is noted for its unusual foliage color. Dense rosettes of woolly, tongue-shaped leaves emerge chartreuse in spring, mature to silvery-green in summer and reacquire a yellowish-green cast in autumn. This cultivar is grown primarily for its thick, soft, velvety, yellowish-green leaves which typically form a rapidly spreading mat approximately 6 to 8 inches tall and 12 to 18 inches wide. Erect spikes of tiny, purplish-pink flowers appear in summer rising above the foliage to about 12 inches tall. If planted in too much shade, the yellow coloring will be less pronounced. Use as a groundcover or edging plant in sunny borders, along paths, or in parkstrips.
Grow in average, dry to medium, well-drained soil in full sun. Drought tolerant. Will tolerate some light afternoon shade, too much shade, however, may impede leaf drying and promote the onset of disease and general mushiness. Avoid overhead watering. Pick off damaged leaves in the early spring, before new growth emerges. Divide in spring or fall. Spreads by creeping stems that root as they go along the ground and can be aggressive in rich soils or in sites that are over-watered.
