Salvia splendens 'Sizzler Scarlet'
Salvia splendens ‘Sizzler Scarlet’ is a scarlet sage grown for compact bedding use and quick color in warm weather. It is treated as an annual across most of North America. In research on heat stress, Sizzler types have been described as more heat sensitive than Vista types under high temperature conditions. That makes siting and irrigation more important during extreme heat. It performs best in full sun with regular watering and excellent drainage. Flowering is generally from summer until frost, but strong heat can reduce quality if plants dry out.
At‑a‑glance
- Group/Class: Sizzler series
- Height × spread: compact habit, size varies by climate (often used as a low bedding salvia)
- Bloom window: summer to frost (varies by climate)
- Color & flower form: scarlet red tubular flowers on upright spikes
- Fragrance: 0
- USDA hardiness: tender perennial in zones 10 to 11, grown as annual in most of North America
- Breeder / Year / Origin: unknown
- Cut-flower notes: not typically used as a cut flower
- Pet safety: unknown
How it differs
- Often used as a compact bedding plant rather than a tall border salvia.
- Can show more stress during extreme heat compared with more heat tolerant lines.
- Needs steadier moisture during hot spells to keep spikes looking clean.
Strengths
- Fits small beds and edging lines.
- Strong red color for mass planting.
- Easy to rotate in seasonal displays.
Care in one minute
- Site: sunny bed with airflow.
- Light: full sun for strongest stems.
- Soil and drainage: well drained soil, do not plant in heavy wet clay.
- Water: water before plants wilt, especially in heat.
- Feeding: light feeding, avoid forcing soft growth.
- Grooming: remove old spikes to push new bloom cycles.
Watch‑outs
- Can lose quality faster in extreme heat if irrigation is inconsistent.
- Overwatering in poorly drained soil can cause decline.
Best uses (tags)
borders, containers, edging, mass planting, warm season color
Provenance note
In university research comparing heat responses in Salvia splendens, Sizzler cultivars are discussed as a heat sensitive type relative to Vista cultivars.
