The Rosy Glow Barberry (Berberis thunbergii 'Rose Glow') is a popular, hardy, deciduous shrub known for its vibrant, ever-changing foliage, offering rose-pink to burgundy hues with white marbling, especially in sun, forming a dense, thorny, rounded plant great for hedges, borders, or accent groupings, prized for its low maintenance, drought tolerance, and deer resistance, with tiny yellow flowers in spring and red berries in fall/winter. 
Key Characteristics:
Foliage: New growth emerges pink and white marbled, maturing to deep reddish-purple or burgundy, providing color all season. Full sun enhances color; shade dulls it.
Size: Grows to about 4-6 feet tall and wide, with a dense, rounded, multi-stemmed habit.
Flowers & Fruit: Small, inconspicuous yellow flowers appear in spring, followed by red berries that birds enjoy and often persist into winter.
Texture: Offers a fine texture that contrasts well with other landscape plants. 
Uses in the Landscape:
Excellent for hedges, borders, foundation plantings, or as a colorful accent.
Its thorny branches make it an effective barrier plant.
Combines well with drought-tolerant plants like sedums, ornamental grasses, and junipers. 
Growing Conditions:
Sun: Prefers full sun for best color, but tolerates partial shade.
Soil: Adaptable to various soil types but needs well-drained conditions (no standing water).
Water: Drought-tolerant once established; water regularly when young and during extreme drought. 
Care & Maintenance:
Pruning: Generally low maintenance; can be left natural or pruned in winter for a manicured look.
Pests/Diseases: Few issues, though powdery mildew can occur.
Wildlife: Deer resistant due to thorns; berries attract birds. 
Considerations:
Can spread slowly via creeping roots or self-seeding.
Tolerates urban pollution and road salt well.
