Botanical characteristics

Cosmos bipinnatus, originally from Mexico, is known for its delicate, feathery leaf structure and large umbels. The 'Sensation Purity' variety blooms with brilliant white flowers 8–10 cm across, each with a yellow center that attracts both bees and butterflies. The plants grow upright and reach a height of 90 to 130 cm, making them ideal for planting at the back of borders or as a standalone in a flowerbed.

The fine, airy foliage contrasts beautifully with the large, white flowers, creating an elegant and tranquil appearance that suits almost any garden style.

Long lasting flowering for a colorful summer

One of the greatest strengths of the Sensation series is its long flowering period. 'Sensation Purity' begins blooming in June and continues until the first frost. Regularly removing spent flowers will encourage the plant to produce new buds. This way, you can enjoy months of continuous white blooms and a harmonious garden appearance.

Location and cultivation

This cosmos variety is easy to grow, making it suitable for both novice and experienced gardeners. It grows quickly and requires little soil, tolerant of both poor and rich soil.

Growing tips:

• Sow indoors from April or directly outdoors after mid-May.

• Choose a sunny location; cosmos blooms best in full sun.

• Use well-draining soil, as cosmos do not tolerate wet roots.

• Keep a planting distance of 30–40 cm for optimal air circulation.

• Water sparingly; once established the plant is drought tolerant.

• Under high wind loads, the long stems may require light support.

Thanks to these properties, 'Sensation Purity' is also ideal for organic gardens, cut-flower gardens and natural borders.

With its sturdy stems and large, white flowers, 'Sensation Purity' is ideal as a cut flower for bouquets. The flowers last a long time in the vase and are perfect for both modern and rustic arrangements.
