Agastache 'Blackadder'
Introduce long-lasting colour, structural interest and a subtle aniseed aroma to your garden with impressive Agastache 'Blackadder'. Not only does this bushy giant hyssop pad out a patch with very attractive flowers during summer and autumn, but it will also be a welcome pit-stop for bees, butterflies and other pollinators. Upright flower spikes in an eye-catching shade of deep purple-blue are dotted with masses of small lilac-coloured flowers which gives the blooms an overall purple haze appearance, while the leaves emit a fresh, spicy fragrance.
Agastache 'Blackadder' tolerates heat and drought well, thriving in a free-draining soil. Its tolerance to what can be harsh summer conditions makes this an undemanding and reliable choice for the border. This giant hyssop is quite hardy, tolerating winter temperatures down to around -10°C in a sunny, sheltered position with free-draining soil. In areas with fairly mild winters, Agastache 'Blackadder' will grow back bigger and bushier each year!
