Helianthus 'Grey Stripe'

Growing upwards of 12' tall, this giant sunflower produces blooms just as big. Huge yellow flowers range from 6-15”. This variety is easy to grow and thrives in conditions that are less than ideal. Plant a row close together to create a natural privacy screen or make a statement. Birds love these seeds. People love them too and they are excellent roasted as a snack.
