Four O'Clock Flowers

Untreated • Unprocessed • Organic • Non‑GMO

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.

Frequently Asked Questions
Why are they called Four O'Clocks?
They earn their name from their tendency to open their blossoms in the late afternoon (typically around 4:00 PM) and remain open throughout the night, closing again the following morning.
Are Four O'Clock flowers easy to care for?
Yes, they are highly regarded by gardeners for their resilience. They are generally drought-tolerant once established and thrive in full sun to partial shade with minimal maintenance.
Do they grow back every year?
In warmer climates (USDA zones 8 and above), they are true perennials and will regrow from their tuberous roots. In colder regions, they are often grown as annuals, though the tubers can be lifted and stored for winter.
