A marginal plant that brings bold, tubular scarlet flowers to the shallow edge of a pond or bog garden each summer, this RHS Award of Garden Merit variety helps keep colour going at the margin in a sunny spot. It's supplied either as a single potted plant in its own basket or as a grouped pack of three, so you can pick the quantity that suits your planting.
Mimulus cardinalis is a marginal pond plant carrying the RHS Award of Garden Merit, a recognition the Royal Horticultural Society gives only to plants it rates as reliably garden-worthy. It suits the shallow margin of a pond or a bog garden in a sunny position, and it keeps colour coming at the water's edge through its scarlet, tubular flowers over the summer. Downy, light green leaves sit behind the blooms, giving the planting a soft backdrop rather than competing with the flower colour.
Buy it as a single plant and you'll receive one Mimulus cardinalis already potted in a 1 litre mesh aquatic basket, ready to lower straight onto the margin shelf. Choose the pack of three instead and you'll receive three plants, each supplied in its own 9cm pot; these will need potting into a mesh basket before they go into the pond, and that basket is sold separately.
Once established, it can be trimmed back at any point during the growing season to keep its shape, and removing the spent flower heads encourages further blooming.
