Heuchera ‘Obsidian’ – 9cm Pot
- Stunning maroon-black foliage
- Sprays of tiny creamy white flowers in summer
- Popular with bees
- RHS Award of Garden Merit
- Great for pots and as groundcover
Spectacular Heuchera ‘Obsidian’ boasts glossy maroon-black leaves that get darker and more dramatic with age, and sprays of creamy white flowers on tall stems in summer. Forming a low mound of foliage, it looks fantastic at the front of a border, contrasting with lighter foliage, or on its own in a pot. The flowers are very popular with bees.
Heuchera ‘Obsidian’ holds the RHS Award of Garden Merit.
Plant in moist, well-drained soil in full sun or part shade, or in pots filled with a loam-based compost such as John Innes no 3.
Deadhead after flowers have faded and remove dead leaves in spring.
Lift and divide overgrown clumps in early autumn, replanting with the crown of the plant just above the surface of the soil.
Feed container-grown heucheras fortnightly in summer with a high-potash feed,
and treat them with Nemasys Vine Weevil Control in spring and autumn to stop vine weevils attacking the plant roots.
When to plant and what to expect at different times of the year
You can plant hardy shrubs, trees and perennials at any time of the year avoiding the two extremes of heat and cold. During the summer months when it is hot and dry the need for watering becomes crucial to aid successful establishment and in the winter when the soil is frozen the plants will not be in active growth either above or below ground and risk getting cold damage. The same is true on the stage or growth you can expect your plants to be delivered in and this will be directly related to the time of year and the season.
When ordering through the year, here’s a summary of what to expect when receiving your plants:
Spring Months: Plants supplied in spring will be starting to show signs of active growth above and below ground.
Summer Months: Plants supplied in the late summer will be more advanced in size and flower stage
Autumn Months: In the autumn plants will be changing colour, showing signs of leaf colour breakdown and be preparing to shut down for winter.
Winter Months: Plants ordered and supplied during the winter months will be dormant and therefore may not be showing growth above the soil level or consist of bare branches with no leaves or bare roots with no soil.
These are all perfectly normal and natural for these types of plants growing in the northern hemisphere. All will still have a very healthy root system that can be planted when the weather is favourable by keeping the new soil level equal to the pot level and therefore not covering the crown of the plant at all. Planting during the autumn and winter months will allow for early establishment in the season and a bigger and better display throughout the main growing season.
