Hey Saskyode,





It is tough to be precise since we do not know when they planted. If you knew that, then start looking after 100 days to 120 days. The following is from some research on the topic:





';Sunflowers are something most of us usually think about in August, but with the arrival of the seed catalogs, winter is a good time to start thinking about which ones you might want to grow this coming year.





Most gardeners are familiar with the tall giant sunflowers exhibited at fairs and field days. But there are three or four dozen other varieties, which come in all heights and many colors, to consider. I've tried most of these in Vermont, and here's how the best performed.





First, you need to understand that sunflowers don't all bloom at the same time. In my trials I grouped them according to bloom time. Early means they bloom in late July or early August. The mid-season ones make up the bulk of varieties commercially available, and bloom in mid- August. The late season sunflowers usually flower from late August to early September.





These dates are approximate for USDA hardiness zone 4 in the Champlain Valley. If you live in a warmer zone, move the dates up a week or two. If colder, move a week or two later.





Another consideration is whether the variety branches or not. If it does, these side branches usually produce smaller flowers after producing larger flowers on the main stems. This way bloom season can be extended another couple weeks or more. '; 1
