Four O'Clock flowers (Mirabilis jalapa) are timeless garden treasures known for their fragrant, trumpet-shaped blooms that reveal themselves as the sun begins to set. Perfect for evening garden enthusiasts, these hardy perennials—often grown as annuals—bring nostalgic charm and vibrant color to any landscape. The plants develop into bushy, lush mounds, often reaching two to three feet in height, making them excellent choices for back-of-border plantings or as a fragrant privacy screen along a patio.
One of the most delightful characteristics of these heirlooms is the sheer variety found within a single planting; you may discover splashes of pink, yellow, red, and white, sometimes all on the same plant or even on a single bloom. Their ability to thrive in poor soil and tolerate heat makes them a low-maintenance favorite for gardeners looking for reliable, long-lasting performance throughout the summer months.
