Penygroes is a compact village and former slate-quarrying community on the A487 trunk road between Caernarfon and Porthmadog, set on the southern slope of the Llŷn Peninsula approach above the Nantlle valley. The village serves as a local centre for the dispersed farming and quarrying communities of the Nantlle and Dyffryn Nantlle area, and its position between the Nantlle ridge — a fine west-facing mountain wall above the disused Dorothea quarry lake — and the Llŷn coastal farmland gives its bees access to a range of landscape types within a short flight. The Dorothea quarry lake, now a diving centre, holds a scrub-edge and quarry-side flora including gorse, buddleia, rosebay willowherb and bramble that give a long summer season on reclaimed industrial ground. Sycamore on the village lane trees and in the old chapel gardens provides the May flow; gorse on the Nantlle ridge and on the common land around the quarry margins flowers from late winter. Hawthorn and blackthorn on the Llŷn farmland hedgerows carry the spring blossom; white clover on the improved pastures of the Dyffryn Nantlle valley floor is the main June and July source. Bilberry and heather on the Nantlle ridge above 300 metres give accessible late-summer upland forage.
Collectors attend swarms in the older stone terraces and chapel buildings of the village centre, along the Dorothea quarry lake scrub and quarry-side gorse and buddleia margins, on the Nantlle ridge hawthorn and gorse fringe above the village, in the farm outbuildings of the Dyffryn Nantlle valley floor pastoral farmland, and in the walled gardens and orchard margins of the older residential properties on the village edge.

Spring opens late. Gorse along the Llŷn coast and blackthorn in the sheltered Conwy and Mawddach valleys begin the year. Sycamore and hawthorn carry May; lime is present in Bangor, Caernarfon and Dolgellau. The mountain heather — bell first, then ling — across the Berwyns, the Carneddau and the Rhinogau brings a reliably strong August crop. Bilberry on oak-fringed hills and bramble in every sheltered combe support midsummer. Coastal sea-lavender on the Dyfi estuary adds character; ivy on slate cottages closes a short, high-quality year.
