Echium wildpretii, commonly known as Tower of Jewels or Tenerife Bugloss, is a stunning biennial or short-lived perennial plant native to the Canary Islands. It is well-known for its tall flower spikes adorned with vibrant red or pink flowers. Here’s some information about Echium wildpretii:
Appearance: Echium wildpretii is a striking plant that can reach impressive heights. In its first year, it typically forms a rosette of large, hairy, silver-green leaves at the base. During its second year, it sends up a single, erect flower spike that can grow up to 6 feet (2 meters) or more in height. The flower spike is covered in tubular, bell-shaped flowers that are bright red or pink in color.
Growing Conditions: Echium wildpretii thrives in Mediterranean climates and prefers full sun. It requires well-draining soil, as it is susceptible to root rot in overly moist conditions. It can tolerate some drought once established but benefits from regular watering during dry periods.
Cold Hardiness: Tower of Jewels is considered frost-tender and is best suited for USDA hardiness zones 9-11. It may not survive freezing temperatures, so it’s important to protect the plant or bring it indoors during cold winters in colder zones.
Wildlife Attraction: The flowers of Echium wildpretii are highly attractive to bees and other pollinators, making it a great addition to pollinator gardens. The abundant nectar production of the flowers supports bee populations and encourages biodiversity.
Life Cycle and Propagation: Echium wildpretii is a biennial plant, meaning it completes its life cycle over two years. During the first year, it forms a rosette of leaves, and in the second year, it produces the tall flower spike. After flowering and setting seeds, the plant usually dies. However, it often self-seeds, and new plants can emerge from dropped seeds.
Gardening Tips: When growing Echium wildpretii, it’s essential to provide it with well-draining soil, adequate sunlight, and sufficient space for the tall flower spike to develop. Support may be needed for the flower spike to prevent it from toppling over in windy conditions. Deadheading the spent flowers can help prolong the blooming period and prevent excessive self-seeding.
Echium wildpretii is a captivating plant that adds vertical interest and a burst of color to gardens. Its unique growth habit and stunning flowers make it a popular choice for plant enthusiasts and those seeking to attract pollinators to their outdoor spaces.
