Snapdragons Delight Gardeners of All Ages

Southern gardeners are heading to nurseries now to purchase plants that will color their winter and early spring gardens. Several kinds of plants will do nicely, but snapdragons are longtime favorites.

Gardening picture
Antirrhinum majus, or snapdragons, are members of the Plantaginaceae family. Technically short-lived tender perennials, snaps are most often grown as annuals because they typically do not last for more than one season. Hailing from the Mediterranean region, plants are hardy in USDA Zones 7-10. Plants may be erect or spreading, and they have alternate, lance-shaped, leaves. Plants with dark colored flowers have dark green or reddish stems while those with white or light colored flowers have light green stems. Flowers are borne in terminal clusters called racemes. Flowers of the “dragon” type, when pinched from the side, open like a dragon’s mouth to the delight of children everywhere, but flowers may also be of the open “butterfly” type. 

Selecting and GrImageowing Snapdragons
Snapdragons come in several sizes and in various colors. Select the tall, erect types that reach two to three feet tall for cutting gardens and back of the border; the intermediates reaching one to two feet tall for bedding and mixed borders; or the dwarf types reaching eight to twelve inches tall for beds, front of the border, edgings, window boxes, and other containers. If a ground-cover effect is wanted, the rock garden hybrids spread out and grow a mere six inches tall. Colors range from pastel tints to bright colors or bicolors, including tints and tones of white, yellow, pink, red, orange, peach, and purple.
 
Culture 
Snaps, as they are often called, grow best in full sun and moist, well-drained soil. Partial shade can help in locations where full summer sun is too intense. Snapdragons prefer cool temperatures and tend to burn out in intense summer heat of the southern United States. In Zone 7 and higher, they are usually planted in fall where they will survive the winter and put on a spectacular spring show. In cool regions (Zones 6 and lower) snapdragons are summer annuals best planted in spring.

Although new plants can be started from seeds, most nurseries and
 big box stores have snaps a-plenty in fall, and they are relatively inexpensive. Many gardeners in areas with cool summers take cuttings in fall and overwinter them for replanting the following spring. Plant seedlings in prepared soil and pinch the stems when young to promote bushiness. After the first flush of bloom, cut back hard and fertilize for a repeat performance.
Watch for and control cultural problems if they occur. If rust appears in a planting, choose another part of the garden the following year. Avoid watering with overhead sprinklers if possible in order to prevent mold, fungal leaf spots, downy mildew, wilt and root rots. Watch for and control aphids with sprays of insecticidal soap or other appropriate controls, and stake tall plant if needed.

Cultivars  
Several series are available in a wide range of colors. Tall cultivars frequently available include ‘Panorama’, ‘Burpee’s Topper’, ‘Spring Giant’, and ‘Rocket’. If the shorter intermediate sizes are desired, select from such cultivars as ‘Princess’, ‘Liberty’, ‘Sonnet’, ‘Pixie’, ‘Sprite’, and ‘Cinderella’. Dwarf cultivars include ‘Tahiti’, ‘Royal Carpet’, ‘Kolibri’, ‘Floral Showers’, and ‘Floral Carpet’. A look at nurseries will reveal many different colors and types. Choose those that suit your needs or your fancy.

Snapdragons for Cutting
Those who grow snapdragons primarily for cut flowers most likely grow the tall to intermediate types. To get the most of cut snaps, select full flower heads that show no sign of aging and that have stems with flowers in three stages of development. Flowers should be fully open at the lowest part of the spike, have some with showing color with partially opened flowers near the top, and a few unopened buds at the tip. This will make the bouquet last longer as buds continue to open toward the tip.
PlungeImage cut stems immediately in cool water. Set aside in a cool place and allow them to condition for at least a couple of hours. Before placing in your arrangement, make sure to remove any spent flowers, dirt or debris. Using a bit of floral preservative will help your flowers last longer. Place your finished bouquet in a room away from air conditioning or heating vents, and change water daily.

Regional Considerations
 With just a bit of care in selecting the proper type for the garden and providing cultural conditions to their liking, almost anyone can have snapdragons to decorate their outdoor and indoor spaces. Gardeners in the South are heading to the nurseries to make their selections about now while those who live in places with very cold winters are taking cuttings and planning to overwinter them for replanting next spring. Gardeners do whatever they must to include these colorful plants in their gardens, whatever the appropriate season.
