Not everyone has the luxury of an outdoor expanse or a surplus of square footage to cultivate a flower garden. But as it turns out, they aren't the only ones who get to enjoy all the beauty that fall gardens embody.
Container gardening is an equally satisfying way to develop your green thumb, no matter the square footage. And with fall in full swing, this curated list of annual autumnal grows that thrive in the sun is a great place to start.
You'll find that each and every one of these plants has something to offer in terms of visual allure and the level of skill it takes to help them bloom.
1. Pansies
Gardening expert Tony O'Neill tells us that pansies are at the top of his list if you're looking to bring a pop of fall garden color into your space. He explains that their resilient nature and ability to thrive in cooler autumn temperatures makes them a great garden grow.
"Plant them in well-drained soil, and make sure they receive at least six hours of direct sunlight daily," he notes. "Keep the soil evenly moist but not waterlogged and deadhead spent flowers to encourage more blooms throughout the fall."
