 member of the mint family Lamiaceae, Stachys officinalis 'Hummelo' is a named cultivar of betony that provides a prolonged summer display. It produces its flower spikes between June and September. Plants are valued for their summer flowering habit and for use where a sustained display is needed. Cutting back spent flower stalks helps keep the clump tidy and encourages fresh growth.

Stachys officinalis 'Hummelo' sits within the Lamiaceae and is a cultivated form of betony grown for its summer-flowering spikes. In the UK it reliably flowers from June to September, making it useful where a continuous summer display is required. The flowering period is the defining seasonal feature to plan around when siting plants. Allow adequate space for individual plants to show their flowering stems without being lost among taller neighbours; position where the flower spikes will be visible at eye level. After flowering, cut back the spent stalks to tidy the plant and to promote fresh shoots; periodic division of congested clumps will rejuvenate older plants. Watering and feeding should follow general perennial practice rather than specialist regimes. Stachys officinalis 'Hummelo' suits perennial borders, cottage-style plantings and mixed herbaceous beds where its summer bloom can be read alongside other mid-season perennials. Reflowering and the season-long presence of blooms make it a useful component for gardeners aiming to extend colour through the summer. Expect its display to begin in June and continue until September, after which maintenance pruning refreshes the planting for the following season.
