Notes
'Mammoth Russian' sunflower (Helianthus annuus 'Mammoth Russian') is an annual for borders, cut flowers, pollinator gardens, and cottage 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 grows fast and stands upright, and it handles dry spells well. Butterflies, bees, and birds visit it. Deer rarely make it their first choice.
Pairs well with Sweet alyssum, Lantana, Aster, and Russian Red Indian shot.
