Tiny Monster Hardy Geranium

Geranium sanguineum ‘Tiny Monster’ is a low, spreading cranesbill with deeply lobed foliage and light red-purple flowers. The Royal Horticultural Society describes it at about 20 cm tall, with spreading rhizomes and flowers that can continue from late spring into early autumn; a specialist nursery also lists a 20 cm height and 50 cm spread. ## Placement and season Use it as an edging plant or ground cover where its rhizomes have room to spread. Full sun or partial shade supports flowering, and the RHS lists chalk, clay, loam, and sandy soils.

The RHS lists a broad 10-to-50-cm mature range for height and spread, while the nursery’s cultivar listing gives 20 by 50 cm. These sources support the existing compact height and spreading width.

Check the perimeter during the growing season and divide or lift rooted sections if the plant is moving beyond its allotted area.
