Plant Common Name

Large-flowered Calamint

General Description

Packing a punch in foliage aroma and floral display, large-flowered calamint is a spectacular perennial. Native to southern Europe eastward into the Crimea, Turkey and Iran, it is a bushy, rounded or mounded plant. Its leaves are medium-green above, gray-green below, and bear tiny hairs. The scent released from the leaves is a delicious blend of sweet fruit with lemon and mint. In midsummer this perennial displays hundreds of bright pink (with lavender hints), tubular flowers at the tops of the many stems. The flowers are loved by nectar-seeking hummingbirds and bees.

Grow large-flowered calamint in full sun to partial shade and well-drained soil. Clay soils must be amended with organic matter to improve drainage. Avoid extremely acidic or alkaline soils. Give this plant full sun except where summers are very hot. There. Plant it in partial or dappled shade. Trimming the stems back by a third after the first summer flowering often results in reblooming. Use this plant as a compact mounded perennial in the mixed border, as a rockery accent or as a delightful addition to an herb or sensory garden. There is a selection, 'Variegata,' that white and green leaves but is otherwise like the parent species.
