- Species and varieties: Melampodium paludosum, commonly known as Butter Daisy or Gold Medallion, is a species of flowering plant in the Asteraceae family. It is known for its bright yellow flowers and compact growth habit. Varieties include 'Derby' and 'Million Gold'.
- Hybrid or heirloom: Melampodium paludosum is typically available as an open-pollinated variety, which means it is not a hybrid. This makes it a good choice for gardeners looking for heirloom or traditional plant varieties.
- Pruning and training: Melampodium paludosum requires minimal pruning. Deadheading spent flowers can encourage continuous blooming throughout the growing season. No special training is needed as the plant naturally forms a neat, bushy shape.
- Fertilization needs: This plant benefits from a balanced, slow-release fertilizer applied at planting time. Additional feeding with a liquid fertilizer every 4-6 weeks during the growing season can promote vigorous growth and abundant flowering. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
- Hardiness zones: Melampodium paludosum is suitable for USDA hardiness zones 9-11. It can be grown as an annual in cooler climates.
- Climate requirements: This plant thrives in warm, sunny conditions and prefers well-drained soil. It is drought-tolerant once established but performs best with regular watering. It can tolerate high heat and humidity, making it ideal for tropical and subtropical climates.
