Four O’Clock Flowers Are Perennial in Garden Zones 7 – 10

Last summer, I had a healthy bed of four o’clocks growing in my garden in the Ozark Mountains. I had never grown four o’clocks before, and several things surprised by about these little, fairy-like flowers. The first thing that surprised me was the size of the four o’clock’s blossoms.

The blossoms of a four o’clock are not large at all, The four o’clock blossom looks a little bit like that of a petunia, but the plant’s habit is different.

While petunia plants get leggy and a bit unsightly as they grow, a bed of four o’clocks doesn’t have that kind of legginess at all. The bed is lush, but the blossoms do not overtake the plants. A  four o’clock bed is a greener space.

Four O’Clocks are Perennial in Garden Zones 7 – 10.

Today  [the final days of March], I walked out into my garden area, and I saw that my current garden area is flush with sprigs of what I believe are new four o’clock babies. Unlike petunias, four o’ clocks are perennial in zones 7 -10.

Four O’Clocks Multiply Rapidly

Last year, I was almost put off by the way that my four o’clock overtook the other flowers that I planted, but this year, I’ll be gardening in soil that has been tainted by the juglone that a huge black walnut tree has produced. Four o’clocks grow in the toxic soil where juglone is pervasive. This year, I’ll welcome any kind of lush flowering plant, and tomorrow, I’ll dig up all of the baby four o’clocks in my current garden, and I’ll move them to my new garden home, where I’ll move in one week.

Four O’clocks may not be the perfect garden flower, but in my garden this year, I’ll welcome every bit a color that they bring to my new garden home.
