The Gerbera daisy, Gerbera jamesonii, is a flowering plant from South Africa in the Aster family, best known for its large, brightly colored blooms held on sturdy stems above a rosette of lobed leaves. Today’s nursery and seed catalog varieties are hybrids that fall into four main classes: single flower, semi-double flower, double flower, and spider flower. In warm regions the plants grow as tender perennials that return each year, while in colder climates they are treated as annuals and planted outdoors after the last frost. In areas with snowy winters it is easiest to start with nursery-grown plants rather than seeds. These daisies grow at a steady pace, producing their first flowers in 14 to 18 weeks and continuing to bloom through summer and into fall. Flower heads reach 3 to 5 inches across, which makes them favorites for cut flower arrangements and patio containers.
Gerbera Daisy Care Basics
Gerberas ask for four things: full sun, well-drained soil, water at the base, and a crown kept above the soil line. Get those right and the plant does the rest.
Light and Temperature Needs
Plant in full sun to partial shade, with afternoon shade in hot climates where intense midday heat stresses the blooms. Gerberas are hardy in USDA zones 8 through 10, where they survive winter outdoors. In cooler zones they perform as annuals or as container plants moved indoors. They are not frost tolerant, so wait until the last frost passes before planting outside, and expect slower growth when nighttime temperatures stay below 55°F. Above 85°F, bloom production slows, which is why afternoon shade in hot regions keeps the flowers coming into early fall.
Soil and Site Preparation
Moist, well-drained soil with a neutral to slightly acidic pH, roughly 6.0 to 6.5, suits them best. Heavy clay that holds water leads to crown and root rot, so raised beds or amended planting holes are worth the effort in wet gardens. Work 2 to 3 inches of compost into the planting area before setting plants, which improves both drainage and moisture retention. Space plants 12 to 18 inches apart so air moves freely between the leaves, which reduces foliar disease pressure.
Types and Flower Forms
Breeders have organized Gerbera varieties into four flower classes, each with a distinct petal arrangement, and all four share the same care requirements.
The Four Flower Classes
| Class | Petal Arrangement | Best Use |
|---|---|---|
| Single flower | One ring of petals around a large center | Cut flowers and naturalistic beds |
| Semi-double flower | Two to three rings of petals | Borders and mixed containers |
| Double flower | Dense petals that often hide the center | Showy containers and front-of-bed color |
| Spider flower | Narrow, quilled, curled petals | Arrangements and novelty color |
The single and double classes dominate garden-center shelves, while spider forms appear mostly in specialty catalogs and florist markets. All classes come in red, yellow, orange, pink, and white, with bicolor varieties increasingly common. Bloom size also varies by class, with doubles often producing the fullest heads and spiders the most unusual texture.
A Name That Invites Confusion
The genus name honors German naturalist Traugott Gerber, and the spelling is close enough to the tool brand behind the Gerber Armbar Drive multi-tool that the two are easy to mix up in an online search. They share nothing but letters: the flower needs sun and water, while the tool needs a pocket.
Planting and Transplanting
Planting depth is the detail that separates healthy Gerberas from plants that rot a month later.
Planting Outdoors After the Last Frost
Set transplants so the crown sits at or slightly above the soil line, never buried. A crown planted too deep holds water against the stem and rots within weeks. Dig the hole twice as wide as the root ball, backfill with amended soil, and water in thoroughly. The planting sequence:
- Harden off nursery plants for 5 to 7 days before setting them out.
- Choose a full-sun site with afternoon shade in hot climates.
- Dig a hole twice the width of the root ball.
- Position the crown level with or slightly above the soil surface.
- Water deeply, then mulch lightly without covering the crown.
Container Planting
Gerberas grow well in pots 6 to 8 inches across with drainage holes. Use a well-drained potting mix and keep the crown above the soil line. Terracotta pots work well because the porous walls wick excess moisture away from the crown, a useful trait in humid climates. Containers let gardeners in cold zones move plants indoors in fall, which is the simplest way to overwinter them.
Watering, Fertilizing, and Deadheading
The biggest Gerbera mistakes involve water on the foliage and a skipped deadheading routine.
How to Water Without Wetting the Foliage
Water at the base of the plant and keep the leaves dry. Wet foliage invites powdery mildew, gray mold, and leaf spot, especially in humid weather. Check the top inch of soil and water when it feels dry, in the morning if possible, so any splash dries before evening. During hot dry spells, check container plants daily, because pots in full sun can dry out within a day.
Feeding and Deadheading for Repeat Blooms
Feed every 2 to 4 weeks during the growing season with a bloom-boosting fertilizer higher in phosphorus than nitrogen. Deadhead spent flowers by cutting the stem back to the base of the plant rather than just removing the head; this pushes new flower buds from the crown. Plan a deadheading pass every week during peak bloom, because each spent stem removed makes room for the next bud.
Deadheading Technique
Grip the spent stem near the crown and pull it gently, or cut it with clean scissors at the rosette base. Removing the entire stem, not just the flower head, keeps the plant tidy and redirects energy into the next round of blooms.
Propagating and Growing from Seed
Established plants are easy to divide, and seed-grown Gerberas are economical when you need many plants.
Dividing Established Plants
Divide every 2 to 3 years in early spring, just as new growth starts. Lift the plant, shake off loose soil, and cut the crown into sections, each with several leaves and a piece of root. Replant the divisions at the correct crown depth and water them in. Water the divisions daily for the first week until new roots grip the soil. Division also rejuvenates plants whose centers have become woody.
Growing Gerberas from Seed
Sow seeds 8 to 10 weeks before the last frost, pressing them into the surface of moist seed-starting mix because light aids germination. Keep the mix at 70 to 75°F, and seedlings appear in 2 to 3 weeks. First flowers follow 14 to 18 weeks after sowing, so time the sowing so blooms arrive when you want them. Hybrid seed does not always come true, and colors can vary from the packet photo. Gerbera seed stays viable for about a year when stored in a cool, dry place, so buy fresh seed for the best germination.
Overwintering and Common Problems
Where winters are cold, Gerberas need protection, and where summers are humid, diseases need prevention.
Overwintering in Cold Climates
In zones 8 to 10, mulch the crown with a few inches of straw or shredded leaves after the first frost. In colder zones, move container plants to a bright, cool room, reduce watering, and stop fertilizing until spring. Indoor winter temperatures around 60 to 65°F suit the plants best, and a bright south window keeps them from going dormant. Gardeners who leave plants in the ground in marginal zones can dig and pot them in fall, then replant after the last frost.
Pests and Diseases to Watch For
- Aphids and whiteflies cluster on new growth and buds; rinse them off or apply insecticidal soap.
- Spider mites show as stippled, pale leaves with fine webbing in dry conditions.
- Leaf miners leave winding pale trails inside the leaves; remove affected leaves.
- Powdery mildew appears as white powder on foliage in humid, crowded conditions.
- Gray mold (Botrytis) attacks spent flowers and wet foliage; remove debris and water at the base.
Check new plants for pests before bringing them indoors in fall, because one infested plant can spread mites to the whole collection. Most disease problems trace back to wet leaves and poor airflow. Space plants properly, water at the base, and clear spent flowers, and the common issues rarely become serious. An early morning check of the foliage catches the first signs while they are still easy to treat.
