The Four O'Clock Heirloom flowers get their name because they bloom in the afternoon and early evening. These Heirloom flowers will be a great addition to your garden! They start blooming in mid-summer up to fall. They are great for attracting butterflies and hummingbirds. The blooms themselves are like an upside-down funnel, and our mix contains several colors. We recommend you soak your seeds before planting them or put a small nick in them. Plant them in full sun; they will withstand partial shade. And as a bonus--the Heirloom flower seeds will grow in any soil! To all of our container gardeners and farmers, the Four O'Clock flowers are great for hanging baskets and pots. Happy growing!!!
