Collection Overview: Curated for its exceptional structural definition and brilliant seasonal illumination, Iberis sempervirens ('Alexander's White') is a cornerstone selection in our permanent border collections. This premium evergreen sub-shrub forms a dense, low-mounding carpet of deep green, needle-like foliage that maintains pristine year-round interest. In mid-to-late spring, the entire canopy erupts into a solid, blinding sheet of pure white blossoms. Selected for its slightly taller, more robust growth profile compared to standard varieties like 'Purity', 'Alexander's White' bridges the gap between delicate floral infill and permanent, drought-tolerant architectural hardscaping lines.

Curated Features

• True Evergreen Architecture: Provides reliable, deep emerald structural interest throughout all four seasons, ensuring your borders and hardscapes look manicured even in winter.

• Blinding Spring Carpet: Explodes in mid-to-late spring with an incredibly dense blanket of snow-white flower clusters that completely obscure the foliage beneath.

• Xeriscaping Stamina: Once established, its specialized root system exhibits outstanding drought tolerance, thriving in hot, lean, and sharply drained environments where traditional groundcovers wilt.

• Manicured Growth Profile: Naturally forms a tight, interlocking mat that serves as a living weed barrier, maintaining a clean edge with minimal shearing.

Collection Placement Questions

• Why is 'Alexander's White' featured in Tree City collections? It delivers a structural, crisp definition that softer perennials cannot match. Standing slightly taller than 'Purity', it provides a more pronounced architectural presence, making it the definitive choice for framing walkways, structural retaining walls, and high-end geometric landscapes.

• How does it serve the rock garden and alpine designer? Reaching a controlled, mounding height, its stems gracefully cascade over stone steps, flagstone joints, and rocky outcroppings, softening sharp vertical edges with living masonry texturing.

• Is it suitable for low-maintenance urban profiles? Absolutely. Its high resistance to heat, drought, and poor soil conditions makes it a bulletproof asset for sun-baked foundation plantings, coastal exposures, and water-wise commercial perimeters.

Design & Companion Care

• Sunlight & Microclimate Parameters: Thrives in full sun exposures; requires maximum solar infiltration to produce its signature dense spring floral canopy.

• Soil Infrastructure: Must be positioned in loose, well-drained soil profiles; highly adaptive to sandy, rocky, or lean soils, but strictly sensitive to standing winter moisture.

• Hydration Protocol: Requires regular moisture during the initial root-establishment phase; once settled, it transitions to a highly independent, low-water regimen.

• Landscape Spacing: Space pots evenly along pathway borders or stone retaining cells to allow the evergreen mounds to mature into a continuous, seamless ribbon of green and white.
