Ditch Stonecrop in flower, photographed in Shaw Woods.

This is an oddity for sure. A lanky plant, 30 to 60 cm tall, with undistinguished leaves and small cream or pale green flowers, it is an unlikely candidate for inclusion in our gardens. Ditch Stonecrop’s only ornamental asset is its colourful seedpods. In late summer, the capsules turn pink — grown in sufficient sun, they turn a bright pink.

Ditch Stonecrop (Penthorum sedoides) grows in damp ditches, often in some shade. However, at least half day sun is better to bring a bright colour to the seed capsules. It tolerates shallow standing water so it could be grown in the shallow shelf area of preformed ponds. It thrives in mucky soil. Ditch Stonecrop spreads by rhizomes.

I appreciate late colour in our garden, and interesting shapes to contrast with the ubiquitous daisy shape are especially valuable. A few customers saw the colourful pods last summer and were intrigued. Is this a plant for everyone? Hardly, but if you have a damp ditch, or a natural pond edge, and would like some late season pink, then Ditch Stonecrop might be the right plant for you.
