Helianthus annuus ‘Mammoth’ Sunflower
The giant of all sunflowers with tall, thick stalks supporting huge heads that tower over the garden.
This single-stemmed variety is a very fast and vigorous grower, perfect for creating living walls or fences, sunflower houses, kids’ gardens and more. Also a great variety for edible seeds or feeding the birds.
