Lavender cotton is a silver-leaved flowering subshrub from the Mediterranean region. Well-adapted to hot, dry sites in Colorado landscapes, it grows very well in areas with drip irrigation. It's fine, soft grey leaves have an aromatic scent and create a beautiful mound of light colored leaves, which look great when planted next to other plants with dark green or burgundy contrasting leaves.
In July, lavender cotton produces numerous bright gold, button-like flowers above the leaves. It's cheery flowers bring a burst of color to midsummer landscapes when many other plants are finished blooming.
Lavender cotton performs really well in the very low water zones at the Demonstration Garden. It performs best in areas with drip irrigation. Avoid planting it in areas with sprinklers since it will develop fungal problems on the leaves.
Shear several inches off the outside of the plant in late winter (March) to remove the old flower stalks. Selectively prune out any dead sections as needed.
