Brookweed is not easily confused with other wild plants on this web site.


Also sometimes known as Water Pimpernel, this little perennial of damp, saltwater soil is not easy to spot as its little white flowers are so small and delicate.  The more distinctive parts of the plant are its hairless spoon-shaped fleshy leaves which form a basal rosette as well as growing alternately up the erect stems, below the little flowers.  Each little 2-3mm flower has five white petals, joined together halfway and they are borne in stalked spikes from June to August.  The fruits are globular capsules which have numerous little red-brown seeds.  This is a native plant belonging to the family Plumbaginaceae

I first saw this little plant at Rath, Co Kerry in 1977 and photographed it in June, 2008 near Sneem, also in Co Kerry.
