Agapanthus 'Queen Mum' is a striking, clump-forming perennial with large, bi-coloured flower heads in white and violet-blue. Blooming in summer, it produces tall stems above lush, strappy green foliage, making it perfect for borders, mass planting or pots. Growing to around 1 to 1.2 metres tall when in flower, it's drought-tolerant and low maintenance once established. Plant in full sun to part shade in well-drained soil for best results.

Supplied in a 200mm pot.
