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 two lovely new crevice beds.



EASTER OPENING TIMES: Good Friday, Saturday, Easter Sunday and Easter Monday 10am-5pm

We are open March to the end of August

Friday, Saturday and Sunday (& Bank Holiday Mondays)  10am-5pm

Monday - Thursday Closed

You can also visit at other times, but only by prior appointment. We accept mail orders throughout the year. If you need to contact us please call 01422 845348 or 07392 856395.
