Once an item ships, you will receive shipment notification and tracking numbers, so you can follow along while your plant travels to your doorstep. We use FedEx, UPS, or USPS at our discretion.
Due to winter weather we have put a hold on shipping to the areas shown below in grey. You can still order now and we will ship the plant to you during an appropriate time for your zone.

Understanding Plant Options
Nature Hills offers plants in two main formats:
- Container Plants: Grown in pots with soil, sized by container volume and plant age
- Bare Root Plants: Dormant plants without soil, sized by height measurements

Tall round balls of stars, the Gladiator Allium (Allium 'Gladiator') adds its rosy purple uniform round spheres that draw butterflies and bees galore! These big purple pompoms stand up and stand out upright to add a whimsical formality to your landscape!
Also known as the Star of Persia, Alliums appear in mid-late spring from among dense clumps of green grassy foliage that carry the family onion scent. Fast-growing into modest-sized clumps with tall, nearly 4-foot stems that seemingly vanish in the summer heat, only to return dramatically next spring!
Very low-maintenance, these slowly expanding clumps thrive throughout USDA growing zones 4-9. These fall-planted bulbs are very easy to grow and the round spikey balls look fantastic in floral arrangements and bouquets!
Planting and Application:
Unique and textural garden specimens, Ornamental Onion are incredible blossoms for focal points in mixed containers, as solitary grouped specimens. Especially when used in long, uniform rows, as winding ribbons, or evenly spaced groupings to dramatically highlight their intriguing blossoms!
You'll want to include these perennials in your bulb gardens and cutting gardens! That way you will have armloads all spring to bring in and decorate your home while leaving many outdoors for pollinators and to add interest to garden beds and borders! Gladiator Allium looks great potted up in containers as thrillers around your seating and entertaining areas, or add accents to porch pots and balcony planters!
- Rounded Tall Purple-Red Blooms
- Grassy Mounds of Green Onion-Like Foliage
- Easy to Grow Perennial Bulbs
- Pollinator-Friendly & Unique Floral Design
- Accents, Vertical Pops of Color, Garden Beds, Borders & Containers
#ProPlantTips for Care:
Allium loves the full sun and can also tolerate a touch of partial shade, especially in the hottest of its preferred growing zones. Plant in very enriched, well-drained soil and provide just enough water to get established. Fall-planted bulbs bring spring beauty, but they shy away from the summer sun. Prune back the flower heads back when they fade (or spray paint them funky colors for summer interest and dried décor) and leave the foliage in place to make food for the bulb. Once the leaves turn yellow you can trim them down cleanly at the ground level.
- Most Color in Full Sun & Partial Shade Too
- Rich Well-Drained Soil
- Slower Growing Dwarf = Maintenance Free
- Prune After Flowering For Possible Rebloom Later
- Easy Care, Needs Little to No Pruning
Gladiator Allium adds unexpected form and color and saturated purple color to your garden beds and borders! Order a pack of bulbs from Nature Hills today! We'll ship your fall-planted bulbs at the proper planting time for your growing zone!
