Grow Sunflowers for daughter’s wedding- Calgary, Ab
(Calgary, Alberta, Canada)
Sunflower 'Pro Cut Red'
I need 60 single stem sunflowers 4’-6’ varieties to grow in a small space. The varieties are pro-cut Red and Pro-cut orange from Sunflowerselections.com. My question is what is the maturity time? I live in Calgary, Alberta, Canada and thought the temperature may slow down the maturity. The wedding is Sept 17 and I would like to have them mature in time. When should I start seeding?
