20 Best Container Plants for Full Sun
Agave
Agave is a genus composed of succulent perennials with extremely slow growth—it may even take up to 30 years. They usually will hold out for about 5 to 10 seasons before releasing a tall stalk of bright flowers.
As the entire plant gradually dies, offsets will naturally be produced from the plant. They are highly tolerant to even the hottest and driest summer seasons.
- Scientific Name: Agave L.
- Common Name: Century Plant
- Appearance: Generally has leathery leaves with spines along the edges, impressively tall stalks, and bright yellow flowers. Agaves can either be unbranched with blooms growing along their stalk or branched and develop flower clusters.
- Hardiness: USDA Zones 8 to 10
- Size: Up to 8 feet
- Soil & water requirements:
- An ideal soil is grave, sandy, or shallow rocky with good drainage. Depending on the species, soil can either be occasionally dry or very dry.
- Water once a week during warmer months but let the soil dry out a little before each watering.
Angel’s Trumpet
This genus is composed of exotic, tropical trees that are well-adapted to container culture as they can reach a manageable size through consistent root restriction and pruning.
Since these plants are native to South America, it thrives in warm and humid temperatures. They are also slightly tolerant to salt, light frost, and drought, as well as resistant to damage caused by deer.
- Scientific Name: Brugmansia
- Common Name: Moonflowers
- Appearance: Small trees that grow trumpet-shaped flowers, ovate-shaped and coarsely toothed leaves, and softly hairy on their stems when young. They typically have one trunk until they branch out.
- Hardiness: USDA Zones 7 to 12
- Size: Up to 30 feet
- Soil & water requirements:
- Prefers soil rich in organic matter, has good drainage and is consistently moist but not excessively wet.
- Water only when necessary (i.e., to keep the soil moist enough). Make sure that the soil won’t dry out too much.
Blanket Flower
Its showy flowers look similar in appearance to blankets that are weaved by Native Americans, hence its common name. Its name could also refer to its “blanketing” growth habit.
Blanket Flowers produce prolific blooms, especially when exposed to full sunlight, and grow well as mass plantings in landscapes and containers.
- Scientific Name: Gaillardia pulchella
- Common Names: Firewheel, Indian Blanket
- Appearance: Has daisy-like flowers with long, flat, and three-toothed petals that are in bright shades of red, orange, and yellow. It also has large, alternate, grayish-green leaves that are strap-shaped and are generally soft and hairy-textured.
- Hardiness: USDA Zones 2 to 11
- Size: Up to 2 feet
- Soil & water requirements:
- Grows best in well-drained, occasionally dry sandy soil with a pH level of 6.0 to 8.0. They rarely survive through harsh winters if they are planted in heavier soil unless they are planted indoors.
- This plant can tolerate infrequent watering and will not survive when water-logged.
Calibrachoa
Calibrachoa is a genus of fairly new ornamentals in horticulture and gardening that is characterized by their resemblance to petunias due to the shape of their flowers.
These plants are native to South America and are suitable for planting in hanging baskets and containers under full sunlight exposure because of their trailing growth habit.
- Scientific Name: Calibrachoa

- Soil & water requirements:
- These plants are sensitive to the pH level of their soils, preferring acidic soils with a pH level of 5 to 6.5. They also require a well-drained soil that is rich in organic matter.
- Calibrachoas require daily watering. The soil must be moist but not excessively wet to prevent root rot. Their containers should have drainage holes for excess water.
Canna Lilies
This heat-loving plant is best grown outdoors and then used as cut flowers indoors but may also be grown as houseplants, as long as they are placed in a sunny location.
Canna lilies were extremely popular since the Victorian period. It gives a tropical feel to gardens and public parks due to its interesting leaves and attractive flowers.
