Salvia 'SoCool Pale Blue' (PBR)

sage (syn. So Cool Pale Blue)

Product Image
Salvia 'SoCool Pale Blue' is a semi-evergreen, upright ‘shrubby’ perennial that produces masses of pale lilac-blue lipped flowers from summer to autumn, held on purple calyces. Its aromatic green foliage complements the delicate blooms, creating a striking contrast. This cultivar is drought-tolerant once established and highly attractive to bees and other insects, making it ideal for enhancing garden biodiversity. Its long flowering season and modestly hardy nature in well-drained, sunny spots make it a perfect choice for low-maintenance borders or pollinator-friendly planting schemes.

How to care for Salvia SoCool Pale Blue (PBR):

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. Pruning, when required, is generally carried out in mid to late spring by trimming back to 15-30cm above the ground (or previous season's growth in older plants) to encourage new growth. Avoid Avoid cutting into old, woody stems.
