Verbascum 'Densiflorum' - 2026

Verbascum densiflorum is a biennial or short-lived, semi-evergreen perennial that forms rosettes of woolly, grey-yellow leaves. In its second year, it produces tall, unbranched spikes adorned with dense clusters of bright yellow flowers, each up to 5 cm across. These blooms are particularly attractive to pollinators such as bees and butterflies. The plant is well-suited for naturalized areas, meadows, and wildflower gardens, adding vertical interest and vibrant color.

Ecologically, Verbascum densiflorum is beneficial for pollinators, providing nectar-rich flowers that attract bees and butterflies. It thrives in well-drained soils and prefers full sun, tolerating a range of soil types, including alkaline conditions. The plant is hardy in UK gardens and is drought-tolerant once established. Deadheading spent flowers can encourage further blooms and prevent undesired self-seeding. Its striking appearance and ecological benefits make it a valuable addition to various garden styles.
