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.

Young Plants (6 months to 18 months old)

Container Size	Actual Volume	Metric Equivalent
2" x 2" x 3"	0.18 - 0.21 dry quarts	0.20 - 0.23 dry liters
4" Container	0.31 - 0.87 dry quarts	0.35 - 0.96 dry liters
4.5" Container	0.65 dry quarts	0.72 dry liters
6" Container	1.4 dry quarts	1.59 dry liters
1 Quart	1 dry quart	1.1 dry liters
5.5" Container	1.89 dry quarts	2.08 dry liters

Established Plants (18 months to 2.5 years old)

Container Size	Actual Volume	Metric Equivalent
2 Quart	2 dry quarts	2.2 dry liters
#1 Container	2.26 - 3.73 dry quarts	2.49 - 4.11 dry liters
5" x 5" x 12"	3.5 - 4.3 dry quarts	3.85 - 4.74 dry liters

Mature Plants (2-4 years old)

Large Plants (3-5 years old)

Container Size	Actual Volume	Metric Equivalent
#5 Container	2.92 - 4.62 dry gallons	12.86 - 20.35 dry liters
#6 Container	5.25 - 6.01 dry gallons	23.12 - 26.42 dry liters
#7 Container	5.98 - 6.53 dry gallons	26.34 - 28.76 dry liters

Bare Root Plants

Bare root plants are sold by height from the root system to the top of the plant. Plants may exceed minimum height requirements.

Common Sizes:

Trees: 1 foot, 2 feet, 3 feet, 4 feet, 5 feet, 6 feet
Shrubs & Perennials: 1 foot, 18 inches, 2 feet

Important Notes

Container Volume Specifications

Trade Gallon Standard: Our containers follow industry-standard "trade gallon" specifications established by the American National Standards Institute (ANSI Z60.1) for nursery stock
Volume Variations: Actual soil volume may vary due to plant root systems and growing medium settlement
Age Indicators: Container size primarily indicates plant age and maturity rather than liquid volume equivalents

Growing Conditions

Plant size can vary based on variety and growing conditions
Container size helps indicate plant maturity and establishment level
Larger containers generally mean more established root systems and faster landscape establishment

Seasonal Availability

Bare root plants are available seasonally when dormant
Container plants are available throughout the growing season
Specific varieties may have limited availability in certain sizes

Planting & Care

Where to Plant

Sunlight: Aim for 4 to 6 hours of direct morning sun to ensure the best bloom production. While this hybrid features improved heat tolerance, providing afternoon shade in warmer climates prevents the foliage from becoming stressed during the hottest part of the day.
Soil: Plant in rich, loamy soil that is well-drained and slightly acidic. If you have heavy clay that holds too much water, mix in organic compost at planting time to improve drainage and prevent the roots from sitting in "wet feet."

Watering Requirements

Water your tree deeply twice a week during its first two growing seasons to help the root system establish itself in the local soil. Mature trees are quite resilient, but you should still provide a deep soaking during extended dry spells to maintain those extra-large white blooms. Inconsistent watering can lead to leaf scorch or smaller flowers because the tree will prioritize its own survival over flower production.

Pruning Tips

This dogwood blooms on old wood, so the best time to prune is in late winter or very early spring before the new growth starts. Limit your work to removing dead branches or small suckers that sprout from the base of the trunk. Think of it like a light seasonal haircut to maintain its natural upright shape without accidentally cutting off the flower buds already set for the spring show.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring just as the buds begin to swell. Avoid using high-nitrogen fertilizers, like those meant for lawns, near the tree late in the summer season. Excess nitrogen late in the year encourages soft, new growth that cannot "harden off" in time for winter, which leaves your tree vulnerable to frost damage.

A Modern Brilliance in Flowering Trees

The Stellar Nova™ Dogwood, botanically known as Cornus x 'Rutstar', represents a revolution in ornamental breeding. Developed by Dr. Thomas Molnar at Rutgers University, this vigorous hybrid combines the elegant spirit of the native flowering dogwood with the rugged resilience of the Kousa species. While many dogwoods struggle with the sweltering heat of midsummer, Stellar Nova™ is a "workhorse" in the landscape, maintaining dense, dark green foliage that resists curling and scorching even when temperatures soar.

Dramatic Late-Spring Bloom

As the early spring blossoms of other trees begin to fade, Stellar Nova™ takes center stage. In late May, it erupts in a canopy of extra-large, bright white floral bracts. These blooms are noted for their high reflectivity; Dr. Molnar describes them as being visible "from a thousand feet away" because they practically glow in the sun. Because it blooms slightly later than traditional varieties, it serves as the perfect partner to pink-flowering dogwoods like 'Scarlet Fire™', creating a synchronized and high-contrast seasonal display.

Four-Season Appeal and Versatility

Growing to a mature height of 10-15 feet with a tidy spread of 10-12 feet, this tree is perfectly sized for modern residential lots. Its upright habit makes it an ideal specimen for a front yard focal point, a courtyard accent, or a refined addition to a flowering border. When autumn arrives, the dark green leaves transition into a rich display of reddish-purple tones before falling to reveal a graceful, sculptural branching structure that provides winter interest. Best of all, this hybrid is sterile, meaning it focuses all its energy on its magnificent flowers and foliage rather than messy fruit production.
