Fun Facts

🌱 Lambrook Mauve is a cultivar developed in England, specifically at Lambrook Nursery in Somerset, known for producing exceptional hardy geranium selections.
🌱 Despite the common name 'geranium,' Geranium is botanically distinct from Pelargonium (which Americans often call 'geraniums'), being fully hardy perennials rather than tender annuals.
🌱 Hardy geraniums self-seed readily in gardens, creating new plants from fallen seed, though seedlings may vary slightly from the parent plant.
