The substantial semi-evergreen foliage has a lustrous, polished quality reminiscent of the volcanic glass from which it takes its name. The leaves maintain their exceptional dark colouration throughout the growing season without fading. In early summer, tall stems bearing sprays of small creamy-white flowers emerge, creating a striking architectural contrast against the near-black foliage. This is an outstanding choice for creating drama and sophistication in shaded borders, providing unmatched contrast when planted alongside lighter-leaved companions or silver foliage plants.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOther benefits:\u003c\/b\u003e darkest available Heuchera foliage, excellent for contrast planting, year-round interest, vigorous growth, low maintenance\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWildlife attraction:\u003c\/b\u003e bees, butterflies, hummingbird hawk-moths, pollinators\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHeight \u0026amp; spread (approx.) at 10 years:\u003c\/b\u003e 0.4m x 0.5m\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePosition:\u003c\/b\u003e partial shade to full shade; some light enhances the glossy sheen\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSoil pH:\u003c\/b\u003e adaptable to most soils; performs best in neutral to slightly acidic conditions\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMoisture:\u003c\/b\u003e moderate watering required; prefers consistently moist but well-drained soil; benefits from mulching\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWinter hardiness:\u003c\/b\u003e very cold hardy to -20°C\u003c\/p\u003e","brand":"Coletta \u0026 Tyson","offers":[{"title":"2 litre","offer_id":57007685403002,"sku":"COL-2L-HEU-OBSX1","price":18.95,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0320\/6758\/4138\/files\/Heuchera-Obsidian-2L-Cedar-Nursery-Surrey-1_405f2cb6-c7e1-426c-a0f2-ba738fd64275.png?v=1768043664","url":"https:\/\/www.landscaping.co.uk\/products\/ct-heuchera-obsidian-herbaceous","provider":"Cedar Nursery - Plants and Outdoor Living","version":"1.0","type":"link"}
