Description

Think pink and puffy for your prairie planting scheme or mixed border. Sanguisorba 'Blackthorn' will bring rosy colour, height, structure, movement and pollinators to your garden to help achieve a gorgeously informal late-summer wilderness. Solid poker-shaped flowerheads emerge a deep claret-red colour before bursting out the fluffy pink flowers which form a light-catching aura. This means you get two great looks all in one plant! The show is long-lasting, low-maintenance and incredibly beautiful. 

Sanguisorba 'Blackthorn' is quite a tall plant and will be happiest in a border where is has room grow. Thriving in a sunny location with free-draining soil, once it’s settled in its quite tolerant to dry conditions and copes well with heat. This clump-forming perennial will need a bit of time to reach full size but each year it will grow back bushier, taller and more prolific. Try pairing this burnet with other sun-loving perennials like Rudbeckia, Echinacea or Salvia to create a balmy summer combination.

Useful information

    • Soak the Sanguisorba 'Blackthorn' roots in water for 3-6 hours prior to planting

    • Plant your "Burnet" bare roots into temporary pots with a multipurpose compost in spring and grow-on in a sheltered spot outdoors

    • Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).

    • Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
