Purple Sensation Ornamental Allium plants offer a perfect combination of bold color, pollinator appeal, and low-maintenance beauty—making them a must-have for dramatic late-spring garden displays. Color: Rich, deep purple spherical flower clusters. Fragrance: Light to none; faint onion-like scent if foliage is crushed. Wildlife & Pest Resistance: Naturally resistant to deer, rabbits, and most pests; attracts pollinators. Planting Zone: Hardy in USDA zones 4–9. Sun Preferences: Full sun for best color and bloom production. Drought Tolerance: High once established; requires well-drained soil. Planting Instructions (for ornamental allium bulbs): Plant in fall, 4–6 weeks before the ground freezes. Select a sunny, well-draining location. Dig holes 4–6 inches deep (about 2–3 times the bulb’s height). Space bulbs 6–8 inches apart. Place bulbs pointed end up, cover with soil, and water lightly after planting. Allow foliage to die back naturally after flowering to nourish the bulb for the following year.
