The Lakeland Horticultural Society holds four National Collections at Holehird - Astilbe, Daboecia, Meconopsis and Polystichum. National Collection status is granted by Plant Heritage, the cultivated plant conservation charity which aims to protect the diversity of garden plants available in the UK. Plant Heritage was established in 1978 when it was realised that many plants were disappearing as fashions changed and the ability to propagate older varieties was lost. National Collection holders seek out, identify, document and conserve plants within their special interest group.
The Society also holds a Lakeland Collection of Hydrangea.
During the period 2017 to 2019 the LHS is hosting a trial of autumn-flowering gentians on behalf of the RHS.
