Imagine your early spring garden sparkling with dozens of delicate white stars!

That's the enchanting beauty of Starflower Alberto Castillo!

This extraordinary spring-flowering bulb produces beautiful, large, star-shaped white flowers that shine like little snowflakes above graceful clumps of soft grey-green foliage.

And there's another lovely surprise!

Starflower Alberto Castillo is delightfully fragrant, producing a sweet floral scent that makes its delicate blossoms even more enchanting.

Native to South America, this unusual variety belongs to the Ipheion group of spring-flowering bulbs and is admired for its vigorous growth and exceptionally beautiful white flowers.

Named in honor of its creator, Alberto Castillo, this special Starflower is distinguished by its larger blossoms and prolific spring flowering.

Growing just 3–6 inches tall, Starflower Alberto Castillo creates a lovely carpet of snowy white flowers above attractive grey-green foliage.

Its compact size makes it especially beautiful along garden pathways, at the front of cottage garden borders, beneath deciduous shrubs, and in decorative spring containers.

Blooming in early to mid-spring, this charming white Starflower helps welcome the new growing season with a sparkling display of delicate blossoms.

Unlike many taller spring bulbs, Alberto Castillo stays low to the ground, making it perfect for filling smaller garden spaces with soft color and texture.

And when planted in generous groups, these beautiful little flowers create a magical, star-studded effect!

Whether you're creating a romantic white garden, brightening a woodland-edge planting, or adding delicate flowers to your spring bulb collection, Starflower Alberto Castillo bulbs bring timeless beauty, sweet fragrance, and irresistible cottage garden charm.

When & How to Plant Starflower Alberto Castillo Bulbs

Plant in Fall for a Sparkling Display of Fragrant White Spring Flowers!

For the most beautiful display, plant your Starflower Alberto Castillo bulbs in fall, once temperatures begin to cool and before the ground freezes.

In Maryland and other Zone 6–7 gardens, October through November is generally an excellent planting window.

Planting Instructions

• When to Plant: Fall, typically October through November in Maryland.
• Planting Depth: Approximately 2–3 inches deep.
• Bulb Spacing: Approximately 3 inches apart for a beautiful, full display.
• Planting Position: Place bulbs with the pointed end facing upward when identifiable.
• Sunlight: Full sun to partial sun.
• Soil: Loose, well-draining garden soil. Avoid locations that remain waterlogged.
• Watering: Water after planting and provide moderate moisture during active spring growth.
• Bloom Time: Early to Mid-Spring.

After flowering, allow the foliage to naturally yellow and die back before trimming it. This helps the bulbs replenish their energy for future seasons.

Helpful Planting Tip: Starflowers look especially beautiful when planted in informal groups rather than straight rows. Scatter bulbs gently over the planting area and plant them where they land for a relaxed, natural-looking display.

In suitable growing conditions, established clumps may gradually increase over time, creating an even more beautiful spring display.

Our Cottage Garden Tip

Create a magical spring garden filled with sparkling white stars!

For a breathtaking display, plant Starflower Alberto Castillo bulbs in generous groups of 15–25 or more, allowing their snowy white blossoms to create delicate drifts of color throughout your garden.

These beautiful little Starflowers are especially lovely along garden pathways, stone borders, rock gardens, and the edges of perennial beds, where their sweet fragrance and delicate flowers can be appreciated up close.

Pair Alberto Castillo with blue grape hyacinths, purple crocuses, miniature daffodils, or soft pink spring bulbs for a charming cottage garden combination.

Their snowy white blossoms also look spectacular alongside dark green foliage and natural stone pathways.

For a peaceful white-themed garden, combine Starflower Alberto Castillo with white crocuses, miniature white daffodils, and other low-growing spring flowers.

And don't overlook containers!

A generous grouping of these fragrant white Starflowers in a decorative planter creates a lovely early spring display near a porch, patio, or garden bench.

Maryland Gardeners: Starflower Alberto Castillo is suitable for many Maryland gardens within its listed hardiness range. Choose a sunny to partially sunny location with excellent drainage, especially during wet winter weather.

Its compact growth habit makes it particularly useful for planting near the front of spring borders, where taller perennials will later emerge and fill the space.

Important: Ipheion is a relatively uncommon ornamental bulb, and pet-safety information may be limited. As a precaution, keep bulbs and other plant material away from pets and children who might ingest them.
