About Salvia splendens 'Vista Red'

Salvia splendens 'Vista Red' · also called Vista Red Salvia, Compact Red Scarlet Sage · flowering

Salvia splendens 'Vista Red' is a compact, early-flowering scarlet sage bred for tidy beds and containers. It throws dense spikes of vivid red tubular flowers from early summer to frost, drawing hummingbirds and bees. Grown as a warm-season annual, it needs full sun, steady moisture and free-draining soil to flower continuously.

Mature size: 25-35 cm tall and 25-30 cm wide; the 'Vista' series is notably dwarf and uniform.

Watch for — Aphids and whitefly: Cluster on soft new growth and flower stems, causing sticky honeydew and distortion. Rinse off or treat with insecticidal soap.

Indoor size vs how big it gets in the wild

Salvia splendens 'Vista Red' reaches its full size within one growing season — there is no "long-term" size, just how big it gets before you harvest or it dies back. Indoors and in a pot, expect 25-35 cm tall and 25-30 cm wide. In the ground with no restriction it is a completely different plant — the 'vista' series is notably dwarf and uniform. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.

Growth rate and years to mature

Salvia splendens 'Vista Red' is a moderate grower. Realistically, expect a single growing season — it reaches full size in one year, then is done. Its feeding profile backs this up: feed every 2-3 weeks through the growing season with a balanced liquid fertiliser, or work a slow-release granular feed into beds at planting. avoid excess nitrogen, which drives leafy growth at the expense of flower spikes.
