|'White Knight' grows to 22 inches tall and wide. A prolific bearer of single, white flowers. Often sold as Chrysanthemum maxiumum. A clump-forming perennial. Fleshy green leaves are toothed and a glossy-dark green. Shasta Daisies make excellent cut flowers, as they are long lasting ( most Chrysanthemums are). Tolerant of many soils, but do require water in hot, sunny climates. Divide clumps every 2 years or establish plants from seed. Grow Shasta daisies if you love to share plants with your friends. You'll all have plenty within 3 years! Remove and discard spent flowers to prolong bloom period.
