You can also start sunflower seeds indoor in small containers for transplanting outdoors, although it is preferable to sow them directly outdoors if possible because they don’t like their roots disturbed. If you expect a frost after sowing, cover the soil with a frost cloth for the night (and don’t forget to remove it in the morning).

I’ve had late frosts after sowing but the sunflower seeds survived fine because they had not sprouted yet. If you have time, you will get the best germination rates if you wait until soil temperatures are consistently 70° to 75☏ (21° to 25☌).īut, for many of us, we need to sow sooner, and you can get by with soil temperatures of 55☏ (13☌) or warmer-just be sure to protect them from critters and cover them if temperatures drop. With seeds selected that you know have time to go from seed to harvest in your growing season, you can sow the seeds as soon as the risk of frost has passed for the season. Look for interesting varieties including dwarf, tall, massive, and colorful ones. I’ve listed suggested varieties in the section on growing sunflowers in containers. These are the ones that grow nicely in containers because they do not need the root space that larger ones do. There are many other hybrids developed to grow taller. Sometimes these adjectives mean the plant will grow tall, sometimes it means the flower head will be very large but the plant may not be particularly tall. I have a long list of recommended seeds for growing giant sunflowers here.

If you want large sunflowers, watch for the words ‘mammoth’, ‘giant’, ‘titan’, ‘monster’, or ‘tall’ in the names or descriptions. Check your seed packets to see what yours has to offer. Sunflowers may be bred for specific colors, heights, flower sizes, types of seed (for birds or humans), to be pollen-free, and more. Here are some sunflowers seeds at Botanical Interests (US Shipping).Įvery type of sunflower is different and not all sunflowers produce edible seeds. Most take between 50 and 120 days, but there are exceptions. If you live in a cold climate, choose varieties that grow from seed to maturity in the number of days available between last frost in spring and first frost in fall.
