Hosta spp. / Hosta hybrid
📖 About this plant
The undisputed kings of the shade garden, hostas are grown primarily for their bold, lush foliage available in shades of green, blue-green, gold, chartreuse, and white-variegated. They send up tall spikes of lavender or white bell-shaped flowers in summer. With thousands of registered cultivars ranging from tiny miniatures to giant specimens, hostas provide unmatched texture and color in shaded areas.
