In the garden

Belonging to the genus Hosta, with roots in northeast Asia, Hosta 'Sum Cup-o-Joe' follows the group habit of forming discrete clumps from its crown and producing seasonal foliage. As a member of the Asparagaceae it is treated as a herbaceous perennial and will die back to the ground each winter before re-emerging the following season. Plant it in partial shade where the soil is loamy, neutral in pH and kept moist but not waterlogged; avoid exposed sites by choosing a sheltered position facing north, east or west. It is rated H7, meaning it is fully hardy through typical UK winters, so it can safely remain in the ground year-round when given the correct siting and soil conditions. Use this cultivar in city and courtyard gardens, patios or containers, and as underplanting for roses and larger shrubs where a clump-forming ground cover fits between stems. It flowers from June to August, and allowing the crown room to expand will let the clump fill a gap over several seasons while respecting its deciduous cycle.
