The Story

Plant Bio

Pinus parviflora is a slow-growing, often irregularly shaped evergreen conifer native to Japan and Korea, prized for its short, twisted needles in bundles of five and its attractive cones that persist for years. 'Glauca' is distinguished by its striking blue-green to silvery-blue needles, which provide excellent year-round color. It typically develops a broad, picturesque, and often windswept habit with age, making it a superb specimen tree.

Uses & Benefits:

The 'Glauca' cultivar is a premier specimen tree, prized for its beautiful silvery-blue needles and artistic, irregular form that develops with age. It provides year-round color and architectural interest, resembling a living sculpture.

Its slow growth and eventual moderate size make it suitable for a range of garden sizes, from suburban lots to large estates. Once established, it is highly drought tolerant, reducing watering needs.

The tree's dense needles provide shelter for birds. Its cones produce seeds that are a food source for various birds and small mammals, such as squirrels and chipmunks.

Planting

How to Grow

Select a site with full sun and excellent drainage.
Amend heavy clay soils with compost and grit to improve drainage.
Dig a hole as deep as the root ball and twice as wide.
Set the tree in the hole, ensuring the root flare is at soil level.
Backfill with the amended soil and water deeply.
Apply a layer of pine bark or needle mulch.

Pro Tip

To encourage a denser, more compact form, pinch back one-half to two-thirds of the new candle growth in spring.

Keep It Thriving

Care Guide

Do

Provide full sun for best color and form.
Ensure soil is well-drained; these pines hate wet feet.
Water during prolonged dry spells, especially when young.
Allow ample space for it to develop its natural, artistic form.

Don't

Do not plant in heavy, waterlogged clay soil.
Avoid planting in deep shade, which leads to sparse growth.
Do not over-fertilize; pines prefer lean soil.
Avoid planting near currants or gooseberries, alternate hosts for white pine blister rust.
