How to Grow and Care for Hosta

Sharing is caring!

Hostas are large-leaved plants that add texture and color to the front of shady beds and borders. Spikes of blue, lavender, or white trumpet-shaped flowers rise above mounds of leaves. Leaves may be heart-shaped, lance-shaped, oval, or nearly round. Foliage runs from lime to dark green, greenish-gold, gray, and blue with many variegated forms.

Most hostas love the shade, but some can tolerate the sun. Plants grown in sun will be more compact and produce more flowers. Hostas go dormant in winter in all regions; the leafy tops all but disappear.
