- Species and varieties: Gerbera is a genus of ornamental plants from the sunflower family (Asteraceae). There are many species and varieties of Gerbera, including Gerbera jamesonii (Transvaal daisy), Gerbera viridifolia, and Gerbera hybrida. Rare varieties may include unique colorations and petal formations not commonly found in standard Gerbera species.
- Hybrid or heirloom: Gerbera seeds can be both hybrid and heirloom. Hybrid varieties are often bred for specific traits such as color, size, and disease resistance. Heirloom varieties are open-pollinated and have been passed down through generations, maintaining their original characteristics.
- Pruning and training: Gerbera daisies require regular deadheading to encourage continuous blooming. Remove spent flowers and any yellowing leaves to maintain plant health and appearance. Pruning is minimal, but removing damaged or diseased foliage is important to prevent the spread of disease.
- Fertilization needs: Gerbera daisies benefit from regular fertilization. Use a balanced, water-soluble fertilizer every 2-3 weeks during the growing season. A fertilizer with a higher phosphorus content can promote blooming. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
- Hardiness zones: Gerbera daisies are typically suitable for USDA hardiness zones 8-11. In these zones, they can be grown as perennials. In cooler climates, they are often grown as annuals or in containers that can be brought indoors during colder months.
- Climate requirements: Gerbera daisies prefer a warm climate with plenty of sunlight. They thrive in temperatures between 70-75°F (21-24°C) during the day and 60-65°F (15-18°C) at night. They require well-drained soil and moderate humidity. Excessive moisture can lead to root rot, so proper drainage is essential.
