Dragon Snaps, scientifically known as Antirrhinum majus, are a popular choice for gardeners, known for their vibrant color and unique visual appeal. Their distinctive flower shape, resembling a dragon’s mouth, gives them their common name. These versatile blooms offer a wide spectrum of hues and add vertical interest to various garden designs.
Understanding Dragon Snaps
Dragon Snaps are herbaceous plants known for their upright growth habit and the characteristic “snapping” action of their flowers when gently squeezed. These captivating blooms come in an extensive palette of colors, including bi-colored varieties, with nearly every shade except true blue. Though short-lived perennials, they are often grown as annuals, especially in colder climates.
These plants are categorized by their mature height, offering flexibility for various garden applications. Dwarf varieties typically reach 4 to 12 inches tall, intermediate types grow to 1 to 2 feet, and tall snapdragons can reach heights of 2 to 4 feet. Dragon Snaps generally bloom profusely during cooler weather, from early spring through fall, often pausing during the intense heat of mid-summer before reblooming as temperatures cool.
Planting Dragon Snaps
Successful planting of Dragon Snaps begins with selecting the optimal time and location. The best time to plant them is in early spring in colder climates or in the fall in warmer regions, as they flourish in cooler temperatures. They can tolerate light frosts, allowing them to be set out a week or two before the average last frost date in spring.
Dragon Snaps thrive in locations that receive full sun, meaning at least six hours of direct sunlight daily, which promotes the most abundant and vibrant blooms. While they can tolerate partial shade, especially in hotter climates where some afternoon shade can prevent scorching, too much shade may reduce their flowering performance. The soil should be well-draining and fertile, with a neutral pH between 6.2 and 7.0. Amending the soil with organic matter can enrich its nutrient content and improve drainage.
When planting from seeds, it is often recommended to start them indoors 8 to 10 weeks before the last expected spring frost, as they are slow-growing. Snapdragon seeds require light for germination, so they should be pressed firmly onto the surface of the soil and not covered. Maintain consistent moisture and provide bright light, such as from grow lights, for about 16 hours daily. For nursery starts, plant seedlings 6 to 12 inches apart to allow for proper growth and air circulation.
Care and Maintenance for Dragon Snaps
Consistent watering is important, particularly for young and newly transplanted Dragon Snaps, as they have higher moisture needs. Once established, they typically require about one inch of water per week, either from rainfall or irrigation. Water near the crown of the plant, allowing the top inch of soil to dry out between waterings to prevent root rot.
Fertilizer application can support continuous blooming. Apply a balanced all-purpose fertilizer, such as a 10-10-10 or 20-20-20 product, every 2 to 4 weeks once the plants begin to produce flowers. Water the soil thoroughly before and after fertilizing to help distribute nutrients and prevent burn. Deadheading, the removal of spent blooms, is an important practice that encourages continuous flowering by preventing the plant from expending energy on seed production. Pinching back the stem tips of young plants, when they are about 6 to 8 inches tall, promotes bushier growth and more flower spikes.
Common Issues and Solutions
Dragon Snaps can encounter certain challenges, though many can be managed with proper attention. One common disease is rust, which appears as brown pustules on leaves and can lead to premature blooming and smaller flowers. If rust becomes an issue, it is advisable to plant Dragon Snaps in a different garden location the following year. They can also be susceptible to other fungal issues like powdery mildew, mold, and root rot, often exacerbated by overly wet conditions. Ensuring well-draining soil and avoiding overhead watering can help mitigate these problems.
Pests such as aphids and spider mites may also affect Dragon Snaps. These can be addressed with horticultural oils or insecticidal soaps for less severe infestations. General troubleshooting for issues like wilting or yellowing leaves often points to improper watering, either too much or too little. Limp, flopping plants and yellowing leaves can indicate overwatering, while dry foliage and browning leaves suggest a need for more moisture. Lack of blooms, especially during hot periods, can be a sign of heat stress, and increased watering or providing afternoon shade can help them recover and rebloom.
