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

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 Instructions

Where to Plant

Sunlight: Aim for at least six hours of direct sun daily to maintain the striking, intense blue color; while it accepts partial shade, the foliage will be a duller green and the habit may become leggier.
Soil: This plant is extremely unfussy and actually prefers poor, lean, well-draining soil, making it perfect for sandy, dry sites, or coastal environments. If you have heavy clay, make sure to significantly amend the area with coarse grit and compost, as this grass will rot if kept in soggy conditions.

Watering Requirements

Water consistently through its first full season to help the root system establish itself; a deep soaking once a week without rain is sufficient. Once mature, Blue Dune Lyme Grass is very drought-tolerant, and overwatering is a much greater risk than underwatering. If water is consistently scarce during a heatwave, you may notice some brown, stressed leaf tips, which signals it is time for a thorough drink.

Pruning Tips

This ornamental grass is grown for its foliage, so the best time to prune is in late winter or very early spring before the new blue shoots appear. Use sharp shears to cut all the old, brown canes down hard to within a few inches of the ground, around 3 to 6 inches tall. This annual haircut removes all the tired growth from the previous season and paves the way for a fresh, vigorous flush of its signature blue foliage.

Fertilizer Needs

This hardy grass is a light feeder and generally does not need supplemental fertilizer, as it thrives in lean soil. If you feel growth is particularly slow in extremely poor conditions, apply a light, slow-release balanced granular fertilizer, like a 10-10-10 blend, just once in the very early spring. What you want to avoid is high-nitrogen fertilizer, especially applied in summer, as this encourages soft, floppy green growth rather than the tough, upright blue texture you desire.

The Grass 'Blue Dune Lyme', Leymus arenarius 'Blue Dune', is an improvement over the species. It has bright blue foliage and stems; provides dusty blue blooms readily throughout the summer!

'Blue Dune Lyme' is an attractive plant that will quickly fill in a large area; spreads by rhizomes and makes an excellent ground cover.

This low maintenance grass needs only occasional watering once it is established. Cut back the upright spiky flowers for a new flush of attractive growth, which looks good well into winter.
