1. Foliage Focus:
   • The primary appeal of coral bells lies in their attractive foliage. Most varieties have deep purple or burgundy leaves, but you can find colors ranging from red to lime green.

   • However, it’s versatile and can tolerate lighting conditions, including full sun.
3. Hardiness Zones:
   • Most Heuchera varieties grow well in USDA Hardiness Zones 4-9, with the sweet spot being zones 5-7.

Heuchera plant problems

Here are some of the most common Heuchera problems and how to address them:

Incorrect Lighting:

• Problem: Heucheras prefer dappled shade or morning sun with afternoon shade. Too much sun can scorch the leaves.
• Solution: Move your Heuchera to a shadier location or provide shade with taller plants.

Watering Issues:

• Problem: Both underwatering and overwatering can be detrimental. Underwatered Heuchera will wilt, while overwatered Heuchera can develop root rot.
• Solution: Water deeply when the top inch of soil feels dry. Avoid constantly wet soil.

Pests and Diseases:

• Pests: Black vine weevils are the most common pest. They chew notches on the leaves.
• Diseases: Fungal diseases like rust and downy mildew can cause leaf spots and discoloration.
• Solution: For pests, hand them off or use insecticidal soap. For diseases, improve air circulation and remove infected leaves. In severe cases, fungicide might be necessary.

Crown Rot:

• Problem: This fungal disease occurs when the plant’s crown is constantly wet.
• Solution: Improve drainage by amending the soil with compost or moving the plant to a raised bed. Avoid overwatering.

Other Problems:

• Heaving: In cold climates, frost heaving can push Heuchera out of the ground.
• Leggy growth: Over time, the crown of the Heuchera might rise above the soil surface.

Solutions:

• Heaving: Mulch around the base of the plant in fall for winter protection.
• Leggy growth: You can bury the exposed stem or divide the plant to encourage new growth.

Heuchera evergreen

While Heuchera is often considered semi-evergreen, some varieties hold their foliage throughout winter in milder climates. Here’s what you need to know:

• Technically Semi-Evergreen: Most Heuchera varieties will lose some older leaves in colder climates, especially during harsh winters. However, they’ll retain a good portion of their foliage, especially the newer growth near the crown.
• Evergreen Varieties: In zones 6 and above (where winter temperatures typically stay above -10°F), some Heuchera varieties can be truly evergreen, keeping their leaves all year round. Here are a few popular evergreen options:
  • Heuchera ‘Obsidian’: This classic variety with dramatic dark purple foliage is known for its excellent winter resilience.
  • Heuchera ‘Green Spice’: This bright green variety with red veins holds its color well and provides winter interest.
  • Heuchera ‘Black Bird’: This dark-leaved beauty boasts near-black foliage that persists through winter.
  • Heuchera villosa varieties: Many Heuchera villosa varieties, like ‘Palace Purple,’ are known for their exceptional winter hardiness and evergreen foliage.
• Factors Affecting Evergreen Behavior: Even evergreen varieties might experience some leaf loss in colder winters or with insufficient winter protection. Here’s how to help them stay evergreen:
  • Planting Zone: Choose Heuchera varieties suited for your climate zone.
  • Winter Mulch: Apply a layer of mulch around the base of the plant in the fall to insulate the roots.
  • Watering: Water occasionally during dry winter spells, especially in exposed locations.
