Echium strictum, commonly known as Viper’s Bugloss or Tower of Jewels, is a semi-deciduous shrub native to rocky, dry areas, and coastal zones of the Canary Islands. It typically grows to a height of 2-6 feet (0.6-1.8 meters) and a width of 1-3 feet (0.3-0.9 meters). This plant is characterized by its erect, branched stems and narrow, hairy leaves. It produces dense spikes of funnel-shaped, vibrant purple flowers in late spring to early summer, which are highly attractive to pollinators such as bees and butterflies.

Echium strictum is valued for its drought tolerance and striking floral display, making it a suitable choice for xeriscaping, rock gardens, and coastal landscapes. It thrives in full sun and requires well-drained soil, preferably sandy or loamy. While it is generally low-maintenance, it may need protection from strong winds due to its tall flower spikes. In regions with suitable climates, it can naturalize and provide a continuous display of color. However, it is important to be aware that Echium species can be invasive in some areas, so gardeners should check local guidelines before planting.CC BY-SA 4.0
