In the garden
Sesleria 'Greenlee's Hybrid' sits within the Sesleria genus, a group of perennial grasses whose natural range stretches across Eurasia and North Africa and includes populations in Great Britain and much of continental Europe. The genus was named for Leonard Sesler and was formally established in the 18th century; taxonomic treatments currently recognise 36 accepted species. Flowering in the UK occurs from May to July, which is the period to assess its seedheads and any decorative interest the selection provides. As with perennial grasses, allow flower stems to develop through late spring and early summer so the flowering display can be appreciated; remove old leaf material during the dormant season to clear space for fresh growth. Observe the plant through its flowering period to decide whether to cut back spent stems or leave them for winter structure. For planting decisions, treat this cultivar in the same way as other perennial grasses in your border or scheme: give it room for a clump to form and consider its seasonal rise in late spring. Its main seasonal interest is the flowering phase from May to July, which defines when it will be most visible in the garden.
