Square-stalked St. John’s Wort (Beathnua fireann)

This native perennial is easily recognizable by - you guessed it - its square stems with distinctive ‘wings’ at the corners. Its oval leaves have translucent dots and the flowers are yellow, blooming from June to September. It will happily inhabit the damper areas in your garden, along ponds for example, growing to up to 60cm in height. The fruits are quite attractive, too - a charming little plant. The bees will agree!
