There’s nothing quite as cheery as these sunflower mixes, and both the blooms and the seed mixes make the perfect gift for a loved one. Here Comes The Sun Sunflower Seed Mix is comprised of 10 different varieties, while Sunny Sunflower Seed Mix features six of our favorites. Sunflowers are annual warm-season crops, so direct sow bulk sunflower seed mixes in the garden once all danger of frost has passed. Sunflowers grow quickly and bloom prolifically, so anticipate armfuls of blooms from either mix. Of course, what you don’t harvest can be left in the field for pollinators and birds to enjoy.
