Notes
'Ronnie' sunflower (Helianthus annuus 'Ronnie') is an annual for borders, pollinator gardens, and cottage gardens. It is hardy to USDA zone 2, or down to -50°F (-46°C). This plant likes full sun, average moisture, and sandy, loamy, or clay soil. Butterflies, bees, and birds visit it, and it tolerates drought. Deer tend to browse other plants first. Blooms open from early to late summer.
Pairs well with Sulfur cosmos, Black Velvet nasturtium, and Red fescue.
