Blackout Heuchera Plant

Our Blackout Heuchera Plant was developed by Dirk Scheys of Belgium. Having leaves that are very dark, almost black, compared to Heuchera Obsidian, the industry standard for dark-leaved Alumroot, Blackout's foliage is darker in color. Also out-performing Obsidian when it comes to vigorous growth, Blackout's compact growth habit makes it ideal for low borders and containers. Known to attract hummingbirds, the creamy white flowers appear midsummer and rise about 18 inches above the starkly contrasting foliage.

Our Heuchera Plants are carefully cultivated without harmful pesticides, making them a safe and striking addition to your garden. Guaranteed to arrive healthy and ready to thrive!

Planting Instructions:

• - Plant in spring or fall for best results
• - Space plants 12-18 inches apart to allow for mature growth and air circulation

Soil Preparation:

• - Ideal soil pH: 6.0-7.0
• - Prefers well-drained, humus-rich soil with good organic matter

Watering Specifics:

• - Water deeply when first planted, allowing the soil to dry between waterings
• - Once established, Heuchera is relatively drought-tolerant but performs best with consistent moisture

Fertilizer Type:

• - Apply a balanced, slow-release fertilizer in early spring
• - Avoid over-fertilizing, as this can reduce leaf color intensity

Pruning and Training:

• - Remove spent flower spikes to tidy the plant and encourage new blooms
• - Cut back damaged or dead foliage in late winter or early spring to promote fresh growth

Additional Pest Management:

• - Heuchera is generally pest-free but can occasionally attract vine weevils; monitor and treat if needed
• - Ensure good air circulation to prevent fungal diseases like powdery mildew
