🌱 Planting Installation
Henry Duelberg Mealy Blue Sage (Salvia farinacea 'Henry Duelberg') is a celebrated, native Texas selection of mealy cup sage renowned for its impressive vigor, floriferous habit, and intense floral color. Discovered in a historic central Texas cemetery, this fast-growing perennial forms a dense, upright, bushy mound two to three feet tall and wide. It features lance-shaped, medium-green foliage with finely serrated edges that emit a subtle herbal fragrance when handled. From mid-spring through autumn frost, it produces a relentless succession of tall, showy flower spikes packed with rich, deep violet-blue blossoms whose calyxes exhibit a characteristic powdery, mealy ("farinaceous") fuzzy texture.
Designated as an official Texas Superstar® plant, 'Henry Duelberg' is far tougher and more disease-resistant than standard seed-grown varieties, demonstrating remarkable resistance to powdery mildew and severe heat stress. Hardy in USDA Zones 7a through 10b, it thrives in full sun and adapts easily to a wide variety of soils ranging from heavy clay-loam to dry, rocky limestone—provided drainage is adequate. Highly drought-tolerant once established, its aromatic foliage keeps deer and rabbits at bay while serving as a major nectar source for hummingbirds, bees, and butterflies all season long.

Fast-growing, upright, clumping herbaceous perennial with a neat, bushy habit. Leaves: Medium-green, lance-shaped to oblong, finely serrated leaves (2–4 in long); emits a faint herbal scent when crushed. Flowers: Showy, deep violet-blue, two-lipped tubular flowers tightly packed on tall, erect spikes (up to 12 in long); calyxes have a mealy or powdery "farinaceous" appearance; heavy bloom from spring through fall frost. Fruit: Inconspicuous, small, dry nutlets enclosed within persistent powdery calyxes. Seeds: Four tiny, dark brown to black nutlets per flower. Bark: Soft, square, green to purplish herbaceous stems that stay soft and non-woody. |

| Mature Height | 2–3 ft (up to 3 ft in flower) |
| Mature Width (Spread) | 2–3 ft |
| Growth Rate | Fast |
| USDA Zone / Chill Hours | Zones 7a–10b (Root-hardy down to 0°F to 5°F); No chill hours required |
PLANT CARE & CHARACTERISTICS
Light Requirements: Full Sun (Requires 6+ hours of direct sunlight daily for sturdy, upright stems and maximum bloom intensity).
Water Requirements: Low to Moderate; requires regular water during establishment, highly drought-tolerant once mature.
Drought Resistance: Exceptional (Texas Superstar® selection praised for enduring severe heat and dry spells).
Soil Type: Highly adaptable; prefers well-draining sandy, loamy, clay-loam, or limestone-rich soils; pH 6.0–8.0; requires good drainage to prevent winter root rot. Amending the soil with organic matter, such as compost, can improve soil fertility and drainage, promoting healthy growth and flowering.
Deer Resistance: Very High (Aromatic foliage naturally deters deer and rabbits).
Pest / Disease Resistance: Outstanding overall resistance; highly resistant to powdery mildew compared to other S. farinacea cultivars; main threat is root rot in waterlogged soil.
Pollination: Bird and Insect-pollinated; a powerful magnet for hummingbirds, native bees, honeybees, and butterflies.
Pruning: Cut back by half in mid-summer if stems become leggy to stimulate fresh growth and a massive autumn bloom flush. Cut down to ground level in late winter before new spring growth emerges.
