Hostas
Hosta spp.
Hostas are popular herbaceous perennial foliage plants grown primarily for their lush, mounding clusters of broad, patterned leaves ranging from solid green to blue-gray and variegated yellow-and-green combinations.
- Light
- Partial shade to full shade, tolerating 3 to 6 hours of indirect light or dappled sunlight per day.
- Water
- Water deeply and regularly, providing about 1 inch of water per week. They prefer evenly moist soil and show signs of drooping or leaf scorching if subjected to prolonged drought.
- Growth
- Herbaceous perennial forming a dense, mounding clump. Mature height typically ranges from 1 to 3 feet with a spread of 2 to 4 feet, featuring a moderate growth rate.
Care instructions
Grow in partial to full shade with rich, moist, well-draining soil. Water regularly during dry spells to maintain consistent moisture, and apply a balanced slow-release fertilizer in early spring as new shoots emerge.
