Captain Kelso Calla Lily (Zantedeschia 'Captain Kelso')

Captain Kelso Calla Lily brings a clean, sculptural look to summer containers and sunny borders with crisp blooms that feel both modern and classic. The upright flowers rise above lush foliage, giving you strong shape and color without needing a complicated planting plan. It performs especially well in pots where moisture and drainage are easy to manage, and the blooms are excellent for simple cut arrangements. If you want a polished seasonal centerpiece that stays easy to care for, this calla is a strong choice.

Distinctive Features

This tender, rhizomatous perennial forms an upright clump of glossy, lance-shaped to arrow-shaped green leaves, often with light speckling. From late spring through midsummer, it produces elegant, funnel-shaped white spathes with a soft yellow tone near the base, held on sturdy stems above the foliage. The habit is compact and upright, making it ideal for tight beds and container designs that need a crisp focal element. Mature size is typically about 18 inches tall and 18 inches wide.

Growing Conditions

• Sun: Full sun to partial sun, with some afternoon shade helpful in hotter climates.
• Soil: Rich, well-drained soil that holds moisture evenly, and avoid heavy, waterlogged sites.
• Water: Moderate, keep the soil surface moist but not soggy during active growth.
• Zones: USDA Zones 8 to 11, grown as a seasonal bulb elsewhere unless overwintered indoors.
• Notable Traits: Strong form for containers and reliable summer bloom when moisture is consistent.

Ideal Uses

• Focal Point: Plant a tight cluster as a focal point in a patio container so the white blooms create a clean, high-contrast centerpiece.
• Containers: Use in pots near entryways and seating areas where the sculptural flowers can be enjoyed up close.
• Border Accents: Tuck into sunny beds to add crisp, refined bloom form among softer textures.
• Cut Flower Gardens: Grow for sturdy stems that bring a polished, minimalist look to arrangements.

Low Maintenance Care

• Watering: Maintain even moisture, especially in containers, since dry swings can reduce bloom quality.
• Feeding: Feed lightly during active growth to support flowering, particularly in pots.
• Grooming: Remove spent blooms and yellowing leaves to keep the planting tidy and encourage continued growth.
• Overwintering: In cold zones, lift and store rhizomes before frost or bring containers indoors to a bright, frost-free space.
