Snapdragons (Antirrhinum majus) are cherished garden flowers, known for their vibrant colors and distinctive, hinged flower shape. This beloved plant adds a whimsical touch to any landscape, reminiscent of a dragon’s mouth opening and closing. Among the many available cultivars, ‘Coraline’ snapdragons stand out as a particularly captivating variety. Their aesthetic appeal makes them a popular choice for adding color and form to outdoor spaces.
Key Characteristics of ‘Coraline’ Snapdragons
‘Coraline’ snapdragons are distinguished by their appealing color palette, which typically ranges from soft coral and peach tones to richer salmon hues. These warm colors are often complemented by a yellow throat within each bloom, adding depth and visual interest. The flowers exhibit the classic snapdragon form, with individual florets densely packed along upright spikes.
This particular cultivar generally falls into the intermediate to tall height range for snapdragons, commonly reaching between 1 to 2 feet in height, though some varieties can grow up to 4 feet tall. Their substantial stature makes them a noticeable feature in a garden. ‘Coraline’ snapdragons typically begin blooming in late spring and can continue to produce flowers consistently through the summer, often extending their display until the first frost of autumn. This prolonged bloom period contributes significantly to their desirability.
Cultivating ‘Coraline’ Snapdragons
Successful cultivation begins with providing them with appropriate light conditions. They thrive in locations that receive full sun, meaning at least six hours of direct sunlight daily, but they can also perform well in partial shade, especially in warmer climates where some afternoon shade can help them endure intense heat. Soil composition is important; ‘Coraline’ snapdragons prefer rich, well-draining soil with a pH that is slightly acidic to neutral, ideally between 6.2 and 7.0. Incorporating organic matter, such as compost, into the soil can enhance both fertility and drainage.
Consistent moisture is important, especially for newly planted seedlings. Once established, they require about one inch of water per week. It is best to water near the crown of the plant, allowing the top inch or so of soil to dry out between watering sessions to prevent overwatering, which can lead to root issues.
While not heavy feeders, nutrients support robust growth and abundant flowering. A balanced, all-purpose fertilizer, such as a 10-10-10 formulation, can be applied when flower stalks first emerge in spring, and then every two to four weeks during the blooming season. Water the plants thoroughly after fertilizing to help the nutrients reach the roots and prevent leaf burn.
Deadheading spent blooms is an important maintenance task that encourages the plant to produce more flowers and extends the blooming period. Pinching off the stem tips on young plants when they have four to six leaves can also encourage bushier growth and more flower-producing side branches.
Snapdragons can be susceptible to certain pests and diseases. Common fungal issues include rust, which appears as yellow or reddish-brown pustules on leaves, and powdery mildew, characterized by a white, powdery growth on foliage. To mitigate these, ensure good air circulation by spacing plants adequately and avoid overhead watering, especially in the evening. Aphids are a common pest, often found on new growth; a strong blast of water or insecticidal soap can help manage their populations.
Garden Applications for ‘Coraline’
Their upright growth and striking color make ‘Coraline’ snapdragons versatile plants for various garden designs. They are well-suited for use in mixed borders and flower beds, where their height allows them to create vertical interest and contribute to different layers of planting. Taller varieties can be positioned at the back of a bed, while intermediate types can fill middle ground spaces.
‘Coraline’ snapdragons also perform beautifully in containers and planters, either as a standalone display or combined with other plants. When arranging them in pots, consider companion plants with complementary colors or trailing habits that spill over the container’s edge.
Beyond garden use, ‘Coraline’ snapdragons are excellent as cut flowers, with good vase life. For the best results, harvest stems when at least three florets have opened on the spike, preferably in the cool morning hours. Removing the lower leaves from the cut stems prevents decay in the water, and placing them upright in water immediately helps avoid stem bending. Companion plants that pair well with snapdragons include cosmos, calendula, nasturtiums, and sweet alyssum, which can also attract beneficial insects to the garden.
