delphinium 'Franjo Sahin'


Delphinium 'Franjo Sahin', commonly known as Larkspur, is a strikingly beautiful perennial that exhibits tall spikes densely packed with semi-double flowers. The blossoms display a captivating shade of blue that can be described as intense and vivid, providing a bold splash of color in the garden. Each individual flower is intricately formed with a central bee, or eye, that is typically a contrasting color, often white or black, adding depth and complexity to the flower's appearance. The foliage of the Larkspur consists of deeply lobed, green leaves that offer a delicate, feathery backdrop to the showy blooms. The plant's overall form is upright and stately, creating an elegant silhouette. The flowers bloom profusely, especially when the old flowers are removed to encourage a second flush of blooms later in the season. With its striking flowers and graceful foliage, Delphinium 'Franjo Sahin' is often used as a backdrop in borders or as an architectural feature in the landscape. Care must be taken in handling the plant as all parts of the Larkspur are toxic if ingested.

  • water dropWater

    Larkspur, the common name of Delphinium 'Franjo Sahin', requires consistent watering to maintain evenly moist soil, particularly during the growing season. It's ideal to water this plant once a week with about one to one and a half gallons per plant, using slow, deep watering methods to encourage root growth. During periods of extreme heat or drought, the frequency may need to increase to twice a week. Always check the top inch of the soil before watering; if it's dry, it's time to water. Reduce watering in the fall and winter months when the plant is dormant.

  • sunLight

    Larkspur thrives best in full sun to partial shade conditions. A location that provides at least 6 hours of direct sunlight is ideal. However, in very hot climates, larkspurs will benefit from afternoon shade to protect them from the intense heat of the day.

  • thermometerTemperature

    Larkspurs prefer moderate temperatures and can generally handle temperatures ranging from a low of about 40 degrees Fahrenheit to a high of 85 degrees Fahrenheit. The ideal temperature range for larkspur is between 60 and 75 degrees Fahrenheit to promote the best growth and flowering.

  • scissorsPruning

    Pruning larkspur helps promote vigorous growth and improves air circulation around the plant. After the first flush of blooms, cut back the flower stalks to just above a set of leaves or a new growth point to encourage a secondary bloom. Prune larkspurs back to the ground in late fall or early winter after the plant has gone dormant.

  • broomCleaning

    As needed

  • bambooSoil

    Larkspur, commonly known as Delphinium 'Franjo Sahin', thrives in a well-draining soil mix with plenty of organic matter such as compost or well-rotted manure. The ideal soil pH for Larkspur is slightly acidic to neutral, ranging from 6.0 to 7.0. A mix of two parts loam, one part peat, and one part sand or perlite can create an optimal growing environment for this plant.

  • plantRepotting

    Larkspur (Delphinium 'Franjo Sahin') doesn't typically require frequent repotting as it is usually grown as an annual or biennial. However, if grown as a perennial, repotting every 2 to 3 years or when it outgrows its current container is best to refresh the soil and encourage healthy growth.

  • water dropsHumidity & Misting

    Larkspur (Delphinium 'Franjo Sahin') prefers moderate humidity levels. It can thrive in the ambient outdoor humidity in most temperate regions, but avoid overly wet or extremely dry conditions to ensure optimal growth and flower development.

  • circleLife cycle

    The Delphinium 'Franjo Sahin', commonly known as "larkspur," begins its life cycle as a seed, sown in late winter or early spring. Upon germination, seedlings emerge and, depending on the climate, may require protection from frosts. The plant then develops a rosette of basal leaves in its vegetative stage, followed by the formation of tall flowering stalks adorned with showy blooms in a wide range of colors, typically during late spring to early summer. After pollination by bees and other insects, larkspur produces fruit containing seeds, which mature by late summer or fall. The plant then enters a period of dormancy, especially in colder climates, where it may die back to the ground while the root system remains alive underground. With the return of favorable conditions in the following spring, larkspur will re-emerge, beginning the cycle anew if it is a perennial variety or will need to be reseeded if it is grown as an annual.

      Spring-Early Summer

    • Delphinium 'Franjo Sahin', commonly known as Larkspur, is often propagated through seed sowing. The most favorable time for sowing seeds is early spring, when the soil is cool but the risk of frost has passed. To propagate Larkspur from seeds, gardeners usually sow them directly into the garden where they wish the plants to grow. The seeds should be planted at a shallow depth, approximately 1/8 inch (about 3mm) deep, to allow for adequate light exposure, which aids in germination. After sowing, the seeds require consistent moisture to germinate, which typically occurs within 2 to 3 weeks. Once seedlings develop true leaves and are large enough to handle, they can be thinned out to prevent overcrowding.
