Osteospermum, commonly known as African daisy, Cape daisy, or blue-eyed daisy, is a genus of flowering plants in the family Asteraceae, which also includes sunflowers, daisies, and asters. These plants are native to South Africa and are widely cultivated for their attractive, daisy-like flowers. With their vivid, kaleidoscope-like colors and striking “blue-eyed” centers, these blooms look almost too exotic for the average backyard. But here’s the secret: they’re surprisingly easy to grow. Ready to bring a little sunshine to your garden? Let’s dig in.

Gardeners around the world are enchanted by the vibrant, daisy-like blooms of the African daisy. Known for their striking colors and resilience, African daisies brighten up gardens and landscapes with their sun-like blooms. The African daisy belongs to the genus Osteospermum and offers a variety of cultivars that delight with their unique beauty and ease of care.

Description

Osteospermum plants have a bushy, spreading growth habit with green to grayish-green, lance-shaped leaves.

Flowers

The flowers are composed of two sets of petals - the outer ray florets, which are colorful and flat, and the central disc florets, which are tubular and often a different color. At the center of each bloom is a distinct eye, often in contrasting shades of blue, yellow, or purple, creating a dramatic focal point.

They have bright, symmetrical blooms with petals that come in a spectrum of vibrant shades, including pink, purple, orange, yellow, and white. Some varieties have two-tone or multicolored petals.

Blooming Season

In cool summer climates, these beautiful flowers produce a long-lasting display from spring to frost. These flowers are relatively quick to flower, blooming around 2 months after sprouting from seed.

Uses

Osteospermum is commonly used as a bedding plant, in borders, rock gardens, containers, and hanging baskets. African Daisies are excellent container plants, thriving in pots, window boxes, and hanging baskets.

Drought Tolerance

Osteospermum is moderately drought-tolerant once established. It prefers regular watering but can survive short periods of dryness.

Pollinator-Friendly

The flowers of African daisies attract a variety of pollinators, such as bees, butterflies, and hoverflies, making them an excellent addition to a wildlife-friendly garden.

Planting African Daisies

How Do I Care For African Daisies? - The Plant Enthusiast

Most African daisies are hybrids, so seeds will not produce “true” plants. Seed-propagated ‘Passion Mix’ may be an exception. We recommend purchasing new plants or propagating from cuttings.

Where to Plant

Their flowers add a vibrant splash of color wherever you decide to plant them in your garden. As long as you choose a sunny spot with well-draining soil, they are quite versatile plants. Here are some suggestions where you can plant them:

Beds and borders: Use them as accent flowers for a mixed flower bed or as a colorful border.
Containers and pots: They grow really well in containers, so they make perfect plants for balconies, decks, or patios. Just make sure the pots have good drainage.
Rock gardens: Due to their drought-tolerant nature, they’re great additions to rock gardens, adding a splash of color!
Slopes and dry areas: Again, with them tolerating dry soil well, this is a great area for them.

The main place to avoid is anywhere shady or with water-logged soil.

When to Plant

Depending on the climate, they can be grown as annuals or perennials. In hardiness Zones 10-11, they can be grown as perennials, coming back every year. In cooler climates (Zones 9 and below), they’re typically grown as annuals and replanted each year.

If you’re planting cuttings or young plants, wait until the frost has passed and temperatures are consistently above 50°F. If you’re planting from seed, start the seeds 6-8 weeks before the last expected frost date. Keep the soil moist until they germinate, and place them in an area with bright indirect light. Give them time to grow sturdy before you transplant them outdoors.

How to Plant

Plant African daisies in well-draining soil. They can tolerate a wide range of soil types but prefer a slightly acidic to neutral pH. Gently remove the plant from its container, taking care not to damage the roots. Give the plants enough space to grow and spread. Place the plant in the hole, making sure the top of the root ball is level with the surrounding soil. When you’ve transplanted your flowers outside, water thoroughly to help the roots settle.

In autumn, before the first frost, prepare a tray or containers with a damp, well-draining seed-starter mix. Take 4- to 6-inch cuttings with at least two leaf nodes on each, remove lower leaves and any flower buds, dip the cuttings into rooting hormone, and plant them, leaving 2 inches of cutting above the soil. Cover with plastic and put them in a mild (60° to 68°F) spot out of direct sunlight. Allow 4 to 6 weeks for rooting, then transplant to potting mix amended with compost and/or aged manure in a well-draining container (at least 4 inches in diameter for a single plant). The African daisy likes slightly acidic soil (pH 5.8 to 6.5). It should continue growing in a mild environment.

Two weeks before moving African daisies outdoors, gradually harden them off. Purchased seedlings should be planted outdoors after the last frost.

African Daisy Care Requirements

Osteospermum are amongst the easiest flowers to grow and care for, producing vibrant, continuous blooms from early spring all the way through to the first frost.

To get the most out of these daisy-like flowers, they will need:

Light: African daisies thrive in full sun (partial shade tends to reduce blooms). African Daisies grow best in full sun, where they receive at least 6-8 hours of direct sunlight per day.
Soil: They like slightly acidic soil (pH 5.8 to 6.5). They prefer well-draining soil, and they can tolerate sandy and somewhat rocky soils.
Water: Keep the soil evenly moist (about 1 inch per week) but avoid standing water. Soggy soil can encourage root rot. African daisies are drought-tolerant once established, but they perform best with regular watering during prolonged dry spells. Ensure even moisture, but avoid waterlogged soil, which can lead to root rot. Water African daisies regularly, ensuring that the soil remains consistently moist but not waterlogged. Overwatering can lead to root rot, while underwatering may cause stress and reduced flowering.
Fertilizer: Apply a balanced fertilizer every 2 to 4 weeks during the growing period. They are not heavy feeders, African daisies will benefit from a light application of balanced, slow-release fertilizer in early spring. This promotes vibrant blooms and sustained growth. Apply a balanced, slow-release fertilizer or organic compost to provide essential nutrients for healthy growth and flowering. Follow the fertilizer package instructions for application rates and timing.
Temperature and Humidity: Moderate to cool night temperatures (below 55°F) promote flower buds. These resilient plants prefer temperate climates and do well in USDA zones 9 through 11.

Apply a 2-3 inch (5-7.5 cm) layer of organic mulch around the base of the plant, keeping it away from the stem.

Pruning African Daisies

Pruning your African daisies will consist of pinching, deadheading, and trimming.

Pinching the tips of your flower’s stem 2 or 3 times in the early season will promote full and bushy growth. Stop doing this when buds appear as this will slow flowering.
Most varieties will need to be deadheaded to continue blooming. Remove spent flowers regularly to encourage continuous blooming throughout the season and maintain a neat appearance. Deadheading, or the removal of spent flowers, is crucial for prolonging bloom time in African daisies. Some varieties now “bury their dead,” meaning new flowers quickly cover old ones. To deadhead your flowers, cut down to the next set of leaves to encourage more growth and blooming. If you don’t deadhead, your flowers won’t bloom throughout the season.
Lightly prune African daisies in early spring or late summer to maintain their shape and promote bushier growth. As temperatures increase during late spring and early summer, flowering will diminish. Trim the plants at this point and continue to care for them, and plants will flower again as temperatures cool in the fall. Mid-season cutting back can reinvigorate African daisies, promoting fresh growth and extending their blooming period.

Overwintering

The African daisy seldom survives a transition indoors for overwintering without a greenhouse or sunroom.

Problems, Pests and Diseases

These flowers aren’t usually afflicted by many problems or pests. African Daisy, is generally a low-maintenance and resilient plant. However, it can sometimes be affected by certain pests and diseases. To minimize the risk of pests and diseases, maintain good cultural practices, such as providing appropriate growing conditions, proper watering and fertilization, and regular inspection and maintenance of plants. Proper cultural practices greatly reduce disease risks. Water at the base of plants to prevent foliar diseases, and ensure good air circulation to ward off issues such as powdery mildew.

Pests

Aphids: These small, sap-sucking insects can cluster on the underside of leaves or on tender new growth. They can cause leaves to curl, distort, or become discolored.
Whiteflies: These tiny, white insects can be found on the underside of leaves and may cause yellowing or curling of leaves. They can also excrete honeydew, leading to the growth of sooty mold.
Spider mites: These microscopic pests can cause stippling, yellowing, or browning of leaves, and may lead to leaf drop. They are more prevalent in hot, dry conditions.

Diseases

Powdery mildew: This fungal disease appears as white, powdery patches on leaves and stems, and can cause leaf distortion or premature leaf drop. To prevent and manage powdery mildew, ensure adequate air circulation around plants, water in the morning, and avoid overhead watering.
Root rot: Overwatering or poorly draining soil can lead to root rot, a fungal disease that causes the roots to become brown, mushy, and decayed. Affected plants may wilt, yellow, or exhibit stunted growth. Prevent root rot by providing well-draining soil and avoiding overwatering.
Leaf spots: Fungal or bacterial infections can cause leaf spots, which may appear as brown or black spots on the leaves. To manage leaf spot diseases, remove and dispose of infected leaves, avoid overhead watering, and ensure good air circulation around plants.

Popular Varieties

For years, many people thought that these flowers must have been dyed due to their vibrant colors. Gardeners loved these features in the original strains but became uninterested as they realized that the flowers closed up at night and on cloudy days. To recapture the public’s enthusiasm, breeders set about developing cultivars with blooms that stayed open much longer. Newer varieties have also included other improvements, including increased heat tolerance (the temperature at which buds will develop) and a reduced need for deadheading (now sometimes eliminated).

Here are some of the most popular varieties:

Osteospermum 4D series: uncommon double flowers, with quilled petals in the centers; flowers do not close, bloom all season long; 8 to 12 inches tall
O. ‘Astra Purple Spoon’: spoonlike petals; blooms from spring through fall; 8 to 18 inches tall
O. ‘Bright Lights Red’ reaches 8 to 12 inches tall
O. ‘Passion Mix’: pink, purple, rose, and white flowers; blooms year-round, most profusely in spring; 6 to 18 inches tall
O. Soprano series: many color options; blooms from spring through fall; 8 to 14 inches tall
