Hosta 'Aureomarginata' - 5 Landscape Sized Clumps Hosta 'Aureomarginata' features a 12-16" tall mound of medium, variegated, oval to heart-shaped leaves which have deep green to olive green centers and thin yellow margins. Foliage mound will typically spread to 18-24" wide. Bell-shaped, lavender flowers appear in summer on stems rising to 34" tall. Easily grown in average, medium moisture, well-drained soils in part shade to full shade. They can tolerate full sun in cool summer climates. It is best in part shade with access to some morning sunshine. Plants perform best in rich, moist, organic soils, with a preference for consistent moisture during the growing season, but plants have tolerance for some dry shade once established. Water is best applied directly to the soil beneath the leaves. Divide plants as needed in spring or autumn. Division is usually easiest in early spring before the leaves unfurl.
