Coreopsis verticillata 'Zagreb' | Tickseed

The Coreopsis verticillata 'Zagreb', commonly known as tickseed, is a perennial plant cherished for its vibrant yellow flowers and its ability to bring a splash of sunshine to any garden border or group planting. Its elegant, fine-textured foliage provides a stunning backdrop to the daisy-like yellow blooms that grace this plant from early summer to early autumn.

Key Features

The Coreopsis boasts a bushy, upright growth habit, reaching an ultimate height of 40 cm, which makes it an excellent choice for a variety of garden settings.
It thrives in all soil types, provided they are well-drained, and can tolerate both sun and partial shade.
The deciduous foliage remains a lush green from spring through summer, offering a continuous display of freshness and vigor.
This cultivar does not produce fruit, allowing it to dedicate its energy to a lengthy flowering period, resulting in a prolonged display of its delightful yellow blossoms.
Although not fragrant, the flowers of the tickseed are a feast for the eyes and attract a myriad of pollinators to the garden.

Tips

For best results, place Coreopsis verticillata 'Zagreb' in a location where it will receive ample sunlight as this encourages the most abundant blooms.
Ensure it receives average water, particularly during dry spells, as it is not drought-resistant.
Regular pruning by deadheading spent flowers will not only improve the plant's appearance but will also stimulate further blooming and prevent unnecessary seeding.
Propagation can be accomplished with ease through division in spring or autumn, helping to maintain plant health and vigor while expanding your garden display.
Monitor the soil moisture level and adjust watering accordingly to maintain the plant's health without overwatering.

Ideal placement of a Coreopsis verticillata 'Zagreb'

For optimal growth and flower display, Coreopsis verticillata 'Zagreb' thrives best in locations that offer full sun to partial shade. It is versatile regarding soil types but flourishes in environments that provide well-drained conditions, which are crucial for the plant's health and vigor. The tickseed's ability to adapt to various soils makes it a reliable choice for gardeners seeking a low-maintenance yet showy perennial for their borders and group plantings, as long as the fundamental requirement for drainage is met to encourage its characteristic vibrant yellow blooms.

How do I plant a Coreopsis verticillata 'Zagreb'?

The ideal time to plant Coreopsis verticillata 'Zagreb' is during the months when there's no risk of frost, preferably in spring or autumn, to give the plant a good start. This species thrives in a location that receives full sun to partial shade and requires well-drained soil of virtually any type. Upon planting, ensure the soil is moist and the plant is well-watered to promote establishment. With an upright to bushy growth habit, this tickseed reaches an ultimate height of 40 cm, forming a vibrant yellow display throughout the summer and into autumn. Regular watering is necessary, especially during dry spells, to maintain its vivacious blooms.

Pruning a Coreopsis verticillata 'Zagreb'

To encourage a longer blooming period and maintain a tidy appearance, regularly deadhead the Coreopsis verticillata 'Zagreb' by removing wilting flowers. Snip the spent blooms back to the first leaf below the flower head. This helps stimulate new growth and can result in a second flush of vibrant yellow blooms. Post-flowering, in late autumn, cut back the foliage to ground level to prepare the plant for winter dormancy and to promote healthy growth in the following season.

Watering a Coreopsis verticillata 'Zagreb'

To maintain the vibrant yellow blooms of Coreopsis verticillata 'Zagreb', consistent watering is key. This species thrives in well-drained soil and requires an average amount of water to sustain its upright to bushy growth habit. It is crucial to establish a regular watering schedule, ensuring the soil remains moist but not waterlogged. During periods of prolonged dryness, it is particularly important to monitor soil moisture levels to prevent stress on the plant. Overhead watering should be avoided to keep the foliage dry and reduce the risk of any potential issues.

Fertilising a Coreopsis verticillata 'Zagreb'

To ensure the vibrant yellow blossoms of Coreopsis verticillata 'Zagreb' reach their full potential, a balanced approach to fertilization is key. A general-purpose fertilizer is suitable for this species, ideally applied once at the onset of spring to kickstart the growing season. As an undemanding plant, it benefits from a controlled-release formula that steadily nourishes it, fostering an upright to bushy growth habit and robust health.

It's crucial to avoid over-fertilizing, which can lead to lush foliage at the expense of flower production. Instead, a single application of fertilizer, as per the manufacturer's instructions, will suffice to support the plant through its extended blooming period. This careful feeding aligns with the average water needs of the plant, ensuring it remains a showy, yet manageable addition to any border or group planting.

The characteristics of a Coreopsis verticillata 'Zagreb'

The Coreopsis verticillata 'Zagreb' thrives with minimal care, making it an excellent choice for gardeners seeking a low-maintenance yet vibrant addition to their landscape. This cultivar is particularly noteworthy for its ability to self-seed under optimal conditions, potentially providing a delightful natural increase of its bright yellow blossoms. Additionally, the tickseed's fine foliage texture adds an airy quality to the garden, creating a subtle contrast against plants with broader leaves.

Separating/dividing a Coreopsis verticillata 'Zagreb'

To maintain the health and promote new growth in Coreopsis verticillata 'Zagreb', division is recommended. Carefully lift the entire plant from the soil, preferably during the cooler months of spring or autumn. Once removed, separate the plant into smaller sections, ensuring each has a portion of root. This rejuvenating practice not only encourages a more robust display of its vibrant yellow flowers but also controls the size and spread of this upright and bushy species. Replant the divisions promptly, allowing space for future growth, and water them well to establish their new positions in the garden.
