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
Container Plant Sizes
Container sizes indicate plant age and growing capacity rather than liquid volume equivalents. Our containers follow industry-standard nursery "trade gallon" specifications, which differ from standard liquid gallon measurements.

Planting & Care
Planting & Care
Nature Hills is pleased to offer native wildflowers like Blue Mist Flower (Eupatorium coelestinum) to plant lovers across the United States! Also known as Ageratum, Blue Bonnet and Boneset, this is a very special blue-violet perennial that simply shines in the summer and fall garden!
One fairy-sized bloom all by itself? You would hardly notice it. But because each bloom is clustered together with 30 others in a charming umbel, the whole becomes much greater than the sum of its parts. Each tiny blossom is an enchanting fuzzy cushion, surrounded by filaments of an ethereal color best described as electric periwinkle.
Multiple umbels develop along the side of the plant, so the flowers just keep coming through the summer and fall. This is quite a magical flower! Hardy throughout a wide range of cool to hot USDA growing zones 6 to 11, these 2-3 feet tall and 2 foot wide perennials can be annuals in cooler growing zones.
Planting and Application:
This airy plant grabs your eye with its lovely little blooms. Plant one on either side of a path to greet your guests. Or devote a sunny corner to a stand of them. Butterflies, including Monarchs and Fritillaries, will stop by to call again and again!
Used extensively in wildlife gardens and natural habitat restoration efforts and pollinator gardens, Ageratum have plenty of nectar to go around in the later parts of the season when they need it most, especially migrating Monarch butterflies!
Snip a few stems for bouquets while these fuzzy periwinkle blossoms light up your Cottage border, perennial gardens, pollinator gardens, and front yard foundation edging to boost curb appeal. Even container gardens can enjoy these fantastic sun garden plants!
- Fabulous Blue-Violet Color
- Late-Season Butterfly Magnet
- Native Annual/Perennial Selection

#ProPlantTips for Care:
Plant this beauty in moist, fertile, humus-rich, well-drained soils in full sun to part shade. Water regularly, especially during drought and summer heat. Deadhead after flowering to keep more blooms returning, then prune your perennials back in the late winter or very early spring.
Because this is a native wildflower, in some areas it may perform a little "too well". You are protected with our subscription to Plant Sentry™, which helps us comply with all local and state regulations for regionally invasive plants.
- Full Sun & Partial Shade
- Well-Drained Rich Soil
- Moderate Moisture Needs
- Deadhead As Blooms Fade & Prune Late Winter
- Hardy Heat-Tolerant Native Plants!
Foamy periwinkle blossoms for late-season butterfly food, the Blue Mist Flower is a great hot climate native wildflower! Be sure to order your very own today from Nature Hills!
