Salvia ‘Lake Onega Imp’ is a compact cultivar bred specifically for pot growing, offering deep purple, tubular flowers that emerge from striking purplish-black spikes and calyxes. This hybrid, combining traits from Salvia guaranitica and Salvia splendens, is an excellent choice for mixed or specimen containers as well as sunny garden borders. With its long flowering season and pollinator-friendly blooms, this salvia is a vibrant, scaled-down alternative to larger varieties like ‘Amistad’ and ‘Amante’.


  • Garden care:
    When planting, incorporate compost to improve drainage and fertility, spacing plants 30-45cm (12-18in) apart and watering thoroughly. To keep the plant blooming throughout the season, promptly remove flower spikes as soon as they begin to fade - this deadheading encourages the plant to produce more flowers rather than putting energy into seed production. In early spring, apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant to retain moisture, suppress weeds, and provide essential nutrients as it breaks down. Ensure the mulch is spread evenly, but keep it away from the stems to prevent rot. Regular watering, particularly in dry spells, will help maintain healthy growth, but be careful not to waterlog the soil, as this salvia prefers well-drained conditions. Finally, consider providing some protection in exposed or colder regions of the UK by covering with a double layer of horticultural fleece or dry mulch (bark chippings/composted pine needles) to insulate the roots, or by using a cloche to protect the plant against hard frosts.
