Notes
'Mammoth Grey Stripe' sunflower (Helianthus annuus 'Mammoth Grey Stripe') is an annual for borders, pollinator gardens, and cottage gardens. It is tender to cold, and the first hard frost will kill it. This plant likes full sun and average to moist soil of most types. It grows tall and fast, and it draws butterflies, bees, and birds. It sits low on the menu for deer. Plant it where its height will not shade smaller plants.
Pairs well with First Knight fountain grass, Bright Lights cosmos, and Cerise Queen yarrow.
