Echium pininana, commonly known as the Tower of Jewels or Giant Viper’s Bugloss, is a striking biennial plant native to the Canary Islands.

Height/Spread: In ideal conditions, Echium pininana can grow to an impressive height of 10 to 15 feet (3 to 4.5 meters) with a spread of about 3 to 5 feet (1 to 1.5 meters). However, in the Irish climate, it typically reaches heights of around 6 to 10 feet (1.8 to 3 meters) and maintains a spread of 2 to 4 feet (0.6 to 1.2 meters).

Position: Echium pininana thrives in full sun or partial shade. In the Irish climate, it benefits from being planted in a sheltered position, as it can be sensitive to strong winds.

Soil: This plant prefers well-draining soils with good fertility. In the Irish climate, it is recommended to grow Echium pininana in fertile, loamy soil that retains some moisture but doesn’t become waterlogged.

Flowering Season: Echium pininana typically flowers in its second year of
