FlowerSeedsForAll Four O’clock

True to their name, Four O'clocks typically begin to open in the late afternoon or early evening as temperatures cool. They remain open throughout the night and often close again by the following morning.

Four O'clocks are versatile and grow well in both containers and garden beds. If you choose a container, ensure it is large enough to accommodate their root system and has proper drainage.

No special care is needed beyond standard watering and sunlight. Because they bloom in the evening, they naturally attract nocturnal pollinators like moths, which are drawn to the white color and the plant's fragrance.

Four O'clocks are generally treated as annuals in cooler climates, meaning they will complete their life cycle in one season regardless of your zone. If you are in a very cold climate, you can start them indoors before the last frost to extend their growing season.

For the best results, plant two to three seeds per hole at a depth of about a quarter-inch. Once they germinate and reach a few inches in height, you can thin them out to ensure the strongest plant has enough space to thrive.
