About Long-leaved mullein
Verbascum longifolium, also known as Long-leaved Mullein, is a robust perennial or biennial plant characterized by its tall, dramatic flower spikes bearing bright yellow blooms. Its long, woolly leaves form an attractive basal rosette. It is ideal for cottage gardens, sunny borders, or as a striking focal point in flower beds where its height and prolonged flowering can be showcased.
Native range
Southern and Southeastern Europe, and Asia Minor
Care tips
It thrives in full sun exposure and well-drained soil, even poor or calcareous, as it does not tolerate waterlogging. Watering should be moderate once established, as it is quite drought-tolerant. Avoid very rich or wet soils, as this can shorten its lifespan and make it susceptible to diseases. A common mistake is overwatering, which leads to root rot.
