- Species and varieties: Schizanthus, commonly known as butterfly flower or poor man's orchid, belongs to the Solanaceae family. The most popular species include Schizanthus pinnatus and Schizanthus grahamii, which are known for their vibrant and intricate flowers resembling orchids.
- Hybrid or heirloom: Schizanthus seeds are typically heirloom varieties, cherished for their unique and delicate blooms. They are not commonly hybridized, allowing gardeners to enjoy the traditional beauty of these flowers.
- Pruning and training: Schizanthus plants benefit from regular deadheading to encourage continuous blooming. Pinching back the tips of young plants can promote bushier growth. Support may be needed for taller varieties to prevent them from flopping over.
- Fertilization needs: These flowers prefer well-drained, fertile soil. A balanced, water-soluble fertilizer applied every 2-3 weeks during the growing season will support healthy growth and abundant blooms. Avoid over-fertilizing, as this can lead to excessive foliage at the expense of flowers.
- Hardiness zones: Schizanthus flowers thrive in USDA hardiness zones 8-10. They prefer cooler climates and can be grown as annuals in regions with mild summers.
- Climate requirements: These flowers require a cool, temperate climate with temperatures ranging between 50-70°F (10-21°C). They do not tolerate extreme heat or frost, making them ideal for spring and early summer planting in cooler regions.
