Obsidian is the result of volcanic lava coming in contact with water. This process results in a glassy finish. Heuchera 'Obsidian' PP14836 exhibits this same glassy sheen and is closer to black than any other Heuchera. The surface and edges of the rounded leaves are so smooth they look like they have been polished. Their undersides are deep purple and exhibit a similar glassy finish.
Though this selection is grown mainly for its unusual foliage, its ornamental value is enhanced by the 24 inch tall scapes which bear smoky purple buds that open to cream flowers. A very compact, tight mound of foliage, making it ideal as an edging or in containers. It's fabulous when paired with brightly colored flowers and foliage in the garden.
Other Details
The most important part of the plant is its root system. Healthy roots are the foundation of a healthy, vibrant plant. The type of plug container used is based on the specific needs of the plants. Perennials offered as bare root traditionally perform better when planted as bare root.Planted in a specialized mix, potted plants have well established root systems. Top growth stage will vary depending on the current life cycle and time of year when shipped. In Winter and early Spring dormant plants may be shipped. Dormant plants may be planted right away, even before the last frost date.
Most bare root varieties are field grown for at least one season, though Hemerocallis and Hosta are grown for two seasons. The bulk of the soil is removed during the harvesting process and the tops of most varieties are trimmed back to the crown. They are graded, packed in shredded aspen or sphagnum moss and stored in freezers until ready to be shipped.

Plant Spacing: Using the maximum mature spread or width of a plant to guide spacing, ensures space to grow to full size. To fill an area sooner, plant them closer together. Just remember, future thinning or transplanting may be needed.
Water: Keep a close eye on newly planted perennials, especially throughout the first growing year. Most early plant loss is due to too much or too little water!
