Michael with plants


Our gold medal winning alpine nursery is one of the UK's top five specialist growers of Alpines. Our passion is the tough plants that flourish in our Yorkshire garden… and therefore should in yours too. We're situated at 900ft in the Pennines, with an average yearly rainfall of 1200mm and have lost count of the number of times visitors have exclaimed “If it'll grow up here, it'll grow anywhere”.


Come and be inspired… whether you're a beginner or enthusiast you'll find a wonderful selection of reliable and more unusual plants to tempt you. The naturalistic garden has interesting planted containers and troughs, rock and scree beds, a 100ft planted wall, woodland planting, ponds and a lovely new crevice bed.

The garden and nursery are open to visitors 10am-5pm on Friday, Saturday and Sunday (& Bank Holiday Mondays)  from 2 March to 1 September inclusive. You can also visit at other times by prior appointment. We accept mail orders throughout the year.


Please note:

1. Only CASH OR CHEQUE payments at the nursery.

2. We have no public toilet at the nursery, and the nearest one is in Heptonstall village (half a mile).
