Salvia Greggii White
🌱 Planting Installation
White Autumn Sage (Salvia greggii 'White') is a popular semi-evergreen subshrub native to Texas and northern Mexico, prized for its crisp, pure white blossoms and outstanding heat tolerance. Growing into a neat, mounding bush two to three feet tall and wide, it features small, oblong, medium-green leaves that release a pleasant minty-herbal aroma when brushed or crushed. From spring through autumn, with peak flushes in spring and fall, slender stems hold racemes of bright white, two-lipped tubular flowers that stand out strikingly against darker landscape backdrops. Salvia Greggii is a staple in xeriscapes, pollinator gardens, and dry perennial borders because it is a magnetic attractor for hummingbirds, bees, and butterflies.

PLANT CARE & CHARACTERISTICS
Light Requirements: Full Sun (Requires 6+ hours of direct sunlight daily for maximum flower production and compact growth; tolerates light afternoon shade in intense heat).
Water Requirements: Low; requires minimal supplemental watering once established.
Drought Resistance: Exceptional (Thrives in hot, dry, Southwestern climates and xeriscapes).
Soil Type: Highly adaptable; prefers dry to medium, sandy, gravelly, or limestone-rich soils; pH 6.0–8.0; strictly requires sharp, rapid drainage to prevent root rot. Amending the soil with organic matter, such as compost, can improve soil structure and fertility, promoting healthy growth and flowering.
Deer Resistance: Very High (Aromatic, resinous foliage naturally deters deer and rabbits).
Pest / Disease Resistance: High resistance to pests and diseases; main threat is root or crown rot in soggy, poorly drained soils or overwatered conditions.
Pollination: Insect and Bird-pollinated; flowers are highly attractive to hummingbirds, honeybees, native bees, and butterflies.
Pruning: Prune back by one-third in late winter or early spring to shape the plant, remove woody dieback, and promote fresh growth. Shear lightly in mid-summer to encourage a heavy autumn bloom flush.
