Rosette mullein is an evergreen perennial herb that displays showy flowers in the late spring/early summer. In the wild, it is found in shaded, rocky mountainous areas. Rosette mullein has a rosette habit (meaning its leaves stretch outwards to prevent being taken over by other plants) and is often cultivated for rockeries.

Water:
Rosette mullein, native to Europe's rocky outcrops, prefers consistent moderate hydration and can tolerate short droughts. Water weekly to keep soil lightly moist. Grown indoors for ornamental appeal, it thrives with increased humidity during active growth for optimal tissue moisture retention.
Fertilize:
For optimal growth of rosette mullein, use a balanced fertilizer in spring and a high-phosphorus formula before flowering, applying monthly. Reduce feeding post-bloom and cease in winter. Ensure soil is damp before application and avoid foliage contact to prevent damage.
Pruning:
Characterized by a dense rosette form and vibrant flowers, rosette mullein thrives with light pruning in early spring to late winter, enhancing growth and air circulation. Remove dead leaves and blooms but avoid heavy pruning to protect its shape and crown, ensuring health and aesthetics.
Propagation:
Rosette mullein is a resilient perennial herb that thrives in rocky conditions. Successful propagation via leaf cuttings requires moisture control and a well-draining medium. A stable environment and gentle handling are essential for optimal rooting success.
Repotting:
Repot rosette mullein every 2-3 years in spring using a slightly larger pot with good drainage. After repotting, maintain consistent moisture and avoid direct sunlight to support recovery and promote healthy growth in its new environment.
