‘Party Balloons’ ornamental onion (Allium ‘Party Balloons’) stands apart because one large bulb can produce several flowering stems, creating a cluster of mauve-pink spheres resembling balloons.

• Sunlight: Full sun to light partial shade.
• Soil: Must be loose and exceptionally well-drained; allium bulbs will rot if left sitting in soggy winter soil.
• Depth & Spacing: Plant the bulb pointed-side up, roughly 15 cm (6 inches) deep and space them 20–30 cm (8–12 inches) apart to allow room for the multiple large flower heads to expand. 

• Flower Size: Massive, spherical purple-pink orbs that can reach up to 20 cm (8 inches) in diameter. 
• Plant Height: Compact to medium growth, reaching about 40–60 cm (16–24 inches) tall. Its shorter stature combined with huge flowers keeps it sturdy and less prone to flopping. 
• Bloom Time: Flowers in late spring to early summer (typically May to June), beautifully bridging the gap between early spring tulips and summer perennials. 
• Hardiness: Highly resilient and rated for Zones 3 to 9, making it incredibly hardy across most Canadian and US climates.
