Introduction
Scabiosa succisa L. is a species of flowering plant in the honeysuckle family Caprifoliaceae. It is native to Europe, including the British Isles, and has been introduced to other parts of the world as an ornamental plant.
Common Names
The plant is commonly known as Devil's-bit or Devil's-bit Scabious, due to its tough, fibrous roots that appear to have been bitten off by the devil. Other names include Pincushion flower, Small scabious, Blue Buttons, and Scabious.
General Appearance
The plant grows to a height of 30-60cm, with multiple stems emerging from a rosette of basal leaves. The leaves are oblong or lance-shaped, with toothed edges and a rough texture. The flowers are produced in rounded heads, consisting of small, tightly packed florets. The color of the flowers varies from pale lilac to deep purple-blue. The plant blooms from July to October and is a favorite of bees and butterflies.
Uses
Scabiosa succisa L. has a long history of medicinal use. The roots of the plant were traditionally used to treat coughs, fevers, and wounds. The plant also has antiseptic and anti-inflammatory properties. Today, it is primarily used as an ornamental plant in gardens and borders, where it adds color and attracts pollinators.
Light Requirements
The Scabiosa succisa L. requires full sun to partial shade for optimum growth. It can tolerate some shade, but it needs at least six hours of sunlight per day. Too much shade leads to reduced flowering and weaker stems.
Temperature Requirements
The Scabiosa succisa L. prefers cool to moderate temperatures. It can tolerate temperatures as low as -15°C and as high as 30°C but prefers temperatures between 13°C-21°C. High-temperature fluctuations can cause the plant to bolt prematurely, reducing its growth and flowering.
Soil Requirements
The Scabiosa succisa L. prefers well-drained fertile soil with a pH of 6.5 to 7.5. It grows well in loam or sandy loam soil enriched with organic matter, such as compost. The soil should be moist but not too wet, as the plant is susceptible to root rot. Adding coarse sand or grit to the soil can improve its drainage.
Proper growth conditions ensure that the Scabiosa succisa L. produces a bountiful supply of flowers, providing aesthetic value in gardens and landscapes.
Cultivation Methods
Scabiosa succisa L. is a perennial herb that requires full sunlight to grow. It can tolerate a wide range of soil conditions, but it prefers well-draining soils with a pH value ranging from 6.0 to 7.5. It can be grown both indoors and outdoors, but it performs best when grown outdoors.
The best time to plant Scabiosa succisa L. is in the spring or fall. Sow the seeds into the soil at a depth of approximately 0.25 inches, and keep the soil moist throughout the germination period. Once the plants have grown to a height of a few inches, they can be transplanted to their permanent growing location.
Watering Needs
Scabiosa succisa L. requires regular watering to maintain healthy growth. Water the plants deeply once a week, or more frequently during hot and dry weather conditions. Ensure that the soil remains moist, but not waterlogged, as this can lead to root rot and other plant diseases.
Fertilization
Scabiosa succisa L. benefits from occasional fertilization to promote healthy growth and improve flowering. Apply a balanced, all-purpose fertilizer to the soil once a month during the growing season. Be sure to follow the manufacturer's instructions on the product label to avoid over-fertilization, which can damage the plants.
Pruning
Scabiosa succisa L. benefits from regular pruning to maintain its shape and promote healthy growth. Remove any dead, damaged, or diseased foliage as soon as possible to prevent the spread of disease and pests. Pinch back the tips of the stems during the growing season to encourage bushier growth and more flowers. Prune the plants back to their basal foliage in the fall or early spring to rejuvenate the plants and promote healthy growth in the coming season.
Propagation of Scabiosa succisa L.
Scabiosa succisa L. is a herbaceous perennial plant with a long blooming period. The plant belongs to the honeysuckle family (Caprifoliaceae) and is commonly known as the Devil’s-bit scabious. The plant is an important host plant for many pollinators, including bees, butterflies, and flies.
Propagation by Seed
Scabiosa succisa L. can be propagated by seeds. The best time to sow the seeds is in the spring or early summer. The first step is to prepare the soil. The soil should be moist and well-drained. The seeds should be sown on the surface of the soil or lightly covered with soil. The seeds will germinate in about 10 to 14 days.
Once the seedlings have reached a height of 5 cm, they can be transplanted to their final location. The plant prefers full sun to partial shade and well-drained soil. It is recommended to space the plants 30 cm apart.
Propagation by Division
Scabiosa succisa L. can also be propagated by division. This method is best done in the spring or fall. The first step is to dig up the plant and carefully separate the roots. Each root should have at least one stem bud on it. The divisions should be replanted immediately into well-prepared soil.
It is important to keep the divisions moist until they have established new roots. The plant prefers full sun to partial shade and well-drained soil. It is recommended to space the plants 30 cm apart.
Propagation by Cuttings
Scabiosa succisa L. can also be propagated by cuttings. This method is best done in the spring or summer. The cuttings should be taken from the young shoots. The cuttings should be around 10 cm long and should be taken from the tip of the shoot.
The cuttings should be planted in well-drained soil. It is recommended to add rooting hormone to the cuttings to increase the chances of success. The cuttings should be kept moist and in partial shade until they have established roots.
Overall, Scabiosa succisa L. is an easy plant to propagate. Whether by seed, division, or cuttings, the plant will reward you with a beautiful display of flowers.
