Intriguing greenish flowers mature into copper-red burrs during the summer months. A good choice for between paving stones or as an edging, it is also ideal in the rock garden, but plants can grow beyond where they are wanted, so keep a firm upper hand. Acaena caesiiglauca is found in mountainous areas and subalpine tussock grasslands, east of the Southern Alps, on South Island, New Zealand.
Seeds can be sown at any time but are best sown in winter or early spring to benefit from a cold spell in the wet compost to break their dormancy. We advise covering seeds very thinly with sand or fine grit to about the depth of the seed size. If the seeds do not come up within 6 to 12 weeks the damp seed tray can be given cold treatment in a fridge for about four weeks. They may still take very many months to appear, so please never discard the pot or tray.
