70 days. A magnificent heirloom variety from Japan, Taiyo is highly regarded for its large, single, yellow flowers on sturdy, medium tall stems. Outer petals are deep-yellow, and short, surrounding a fuzzy, dark chocolate colored center which makes for a stunning contrast. Flowers are 8-12” wide yet are upright and do not droop. Plants are 5-6' tall plant. This variety is a popular cut flower. If left uncut, Taiyo provides an amazing display as the flower opens, attracting pollinators to your garden. The small seeds are edible and will be a welcome fall treat for many types of wildlife. SSE
Growing Instructions (for USDA Zone 5b):
Sunflowers are easy to grow from seed outside provided that they are kept moist during germination & seedlings are protected from slugs (use Sluggo). Also, protect plants from groundhogs & deer. Sow seeds outside 6/1-6/30, 6” apart. Thin to 18” for full size plants.
For cut flowers, harvest young (newly opened) flowers with tight centers and place in water, out of the sun immediately.
Seed Saving Instructions for gardeners:
Sunflowers are an easy seed saving crop although they will cross easily with other sunflower varieties. Minimum population size: 5. Cut seedheads when seeds are mature but before the birds get them all! Place seedheads to dry in a dry location with good air circulation.
