Red Dragon Heuchera, also known as Heuchera 'Red Dragon', is a cultivar valued for its striking, deep red foliage and compact growth habit. Here are some key points about this plant:

1. Appearance: Red Dragon Heuchera features large, deeply lobed leaves that are a rich burgundy-red color. The foliage has a glossy appearance, adding to its visual appeal. In spring and early summer, slender stems rise above the foliage, bearing small, bell-shaped flowers in creamy white or pale pink.

2. Size: This cultivar typically forms a compact mound of foliage, reaching a height of about 20 to 26 inches with a spread of 26 to 30 inches. Its relatively small size makes it suitable for use in containers, borders, or as a ground cover.

3. Flowering: While the primary attraction of Red Dragon Heuchera is its foliage, it does produce delicate, bell-shaped flowers in spring and early summer. The flowers are relatively small and inconspicuous compared to the bold foliage.

4. Sun and Soil Requirements: Red Dragon Heuchera prefers partial shade to full shade. It thrives in well-drained soil with plenty of organic matter. While it can tolerate some sun, especially in cooler climates, it may require more moisture in hotter, sunnier locations.

5. Watering: This cultivar has moderate water needs and benefits from regular watering to keep the soil consistently moist, especially during hot, dry periods. However, it is important not to overwater, as this can lead to root rot and other problems.

6. Maintenance: Red Dragon Heuchera is relatively low-maintenance. Remove any damaged or discolored foliage as needed to maintain plant health and appearance. Division of the clump every few years can help rejuvenate older plants and maintain vigor.

7. Landscape Use: Red Dragon Heuchera adds bold color and texture to shaded garden areas. It is often used in borders, edging, mass plantings, rock gardens, and containers. Its deep red foliage provides year-round interest and pairs well with other shade-loving plants in mixed plantings.

Overall, Red Dragon Heuchera is prized for its striking foliage color, compact habit, and adaptability to shaded conditions. It adds beauty and interest to garden landscapes throughout the growing season and provides a dramatic focal point in shaded areas.
