Geranium 'Brookside' (Cranesbill)
Geranium ‘Brookside’ is a hardy cranesbill that quickly forms a spreading mound of dissected green leaves, topped with masses of clear violet‑blue flowers with pale centres. It’s an easy, generous perennial for weaving through borders and keeping the garden looking fresh for months.
Plant in moderately fertile soil that drains well, in sun or light shade. It’s ideal at the front of borders, alongside roses, or as ground cover between taller perennials. Once established it’s resilient, but it looks its best with occasional watering in prolonged dry spells.
For the longest display, deadhead spent flowers and give the plant a light trim if it becomes untidy—this often encourages another burst of blooms. A spring mulch of compost helps retain moisture and feeds the soil for stronger growth and flowering.
The cool, blue‑violet tones are perfect with whites, soft yellows and silvery foliage, and the open, saucer‑shaped flowers also make a natural partner for ornamental grasses. It’s a reliable filler that also feels special when planted in larger drifts.
You’ll receive one plant in the stated grade, dispatched in season for planting. Settle it in well for the first few weeks and it will soon knit into a long‑flowering patch that returns each year with minimal fuss.
