An internet search last weekend finally enabled me to identify a mystery shrub that first saw at Duffryn Rhondda (SS838957) in 2011, but which we happened to pass again over the weekend. Known also as Broom Tea-tree Leptospermum scoparium, Mānuka utilised by bees in New Zealand produce honey famed for its medicinal properties. I'm sure the local bees enjoy the sweetness of this single shrub, though I doubt Welsh Mānuka honey is a viable business proposition! The presence of a row of Eucalyptus trees nearby indicates an Antipodean influence in the local planting scheme, but the location of the scrub amongst natural scrub indicates the possibility that the plant could have resulted from self-seeding - although no search for a parent plant was made in local gardens. I'd be interested to hear if anyone else has encountered this distinctive species elsewhere locally?
