Eden Brothers Four O'Clock Seeds

Yes, they can be grown in containers, though you will need a pot that is at least 12 inches deep to accommodate their root system. Ensure the container has adequate drainage and receives full sun throughout the day.

Since these plants reach a mature height of 24 inches, it is best to space them about 12 to 18 inches apart. This spacing allows for proper airflow, which helps keep the plants healthy and prevents fungal issues.

While you can start them indoors 4 to 6 weeks before the last frost, Four O'Clocks are generally easy to direct sow once the soil has warmed up in the spring. If you live in a region with a shorter growing season, starting them indoors is a safer bet to ensure blooms by late summer.

Four O'Clocks are tender perennials that are typically grown as annuals in most climates. While they are hardy in USDA zones 2-10, they will die back with the first hard frost, so you should plan to replant them each season unless you live in a very warm, frost-free climate.

These plants thrive in full sun, which means they require at least 6 to 8 hours of direct sunlight daily. While they may tolerate partial shade, you will see the best bloom production and overall plant vigor when they are placed in a spot with maximum sun exposure.
