Notes
'Mammoth Grey Striped Sunflower' (Helianthus annuus 'Mammoth Grey Striped Sunflower') is an annual for borders, containers, and low maintenance gardens. It is tender to cold, and the first hard frost will kill it. This plant likes full sun and dry to moist soil of most types. It blooms from early to late summer on stems that reach about 120 inches tall. Butterflies, bees, and birds visit the flowers. Deer usually look elsewhere for a meal.
Pairs well with First Knight fountain grass, Texas bluebonnet, and Sea holly.
