Dawn Redwood ‘Sheridan Spire’ – Metasequoia glyptostroboides is a deciduous conifer with a distinctly narrow, columnar habit that makes it perfect for smaller gardens where space is at a premium. This cultivar offers all the charm of the species with its feathery, bright green foliage that emerges in spring, but with a much more compact and upright form. The slender silhouette creates an elegant vertical accent, reaching skyward with minimal spread, making it ideal for planting in borders, alongside pathways, or as a distinctive specimen tree.
The foliage of ‘Sheridan Spire’ is particularly attractive throughout the growing season. In spring, the soft, needle-like leaves emerge in a fresh, vibrant green that catches the light beautifully. As summer progresses, the foliage matures to a deeper green, providing a lush backdrop for other plants. Come autumn, the tree puts on a spectacular display as the needles turn rich shades of bronze, copper, and russet before falling to create a golden carpet beneath. This seasonal transformation adds year-round interest to any planting scheme.
Unlike many conifers, Dawn Redwood is deciduous, shedding its needles in winter to reveal attractive, fibrous, reddish-brown bark that adds structure and texture to the garden during the dormant months. The bark becomes increasingly fissured and characterful with age, developing deep ridges that enhance the tree’s winter appeal. The bare branches create an elegant silhouette that looks particularly effective when backlit by low winter sun or dusted with frost.
This cultivar is remarkably adaptable and hardy, tolerating a wide range of soil conditions from clay to loam, though it performs best in moist, well-drained soils. It has a particular affinity for damp conditions and can even tolerate occasional waterlogging, making it an excellent choice for planting near ponds or in areas with heavier soils that retain moisture. The tree establishes relatively quickly once planted and maintains steady growth throughout its life.
‘Sheridan Spire’ works beautifully in formal settings where its narrow form can be used to create vertical rhythm, or in more naturalistic plantings where its seasonal changes complement perennials and other deciduous trees. The compact spread means it won’t overwhelm neighbouring plants, whilst the height provides valuable structure and screening. It’s also an excellent choice for wildlife gardens, as the dense foliage provides nesting sites for birds.
Care Guide
Plant in full sun or partial shade, though the best foliage colour and most compact growth occurs in sunnier positions. Choose a planting site with moist, fertile soil that doesn’t dry out completely during summer. Dig a hole twice the width of the root ball and incorporate plenty of organic matter to improve moisture retention.
Water regularly during the first two growing seasons to help establish a strong root system, particularly during dry spells. Once established, the tree is relatively drought-tolerant but performs best with consistent moisture. Apply a generous mulch of organic matter around the base each spring to conserve moisture and suppress weeds, keeping it clear of the trunk.
Feed annually in early spring with a balanced, slow-release fertiliser to encourage healthy growth. Pruning is rarely necessary due to the naturally neat habit, but any damaged or crossing branches can be removed in late winter whilst the tree is dormant. The narrow form is maintained naturally without intervention.
‘Sheridan Spire’ is fully hardy and requires no winter protection once established. It’s largely pest and disease-free, making it a low-maintenance choice for gardens. The tree tolerates urban pollution well and adapts to most soil pH levels, though slightly acidic to neutral conditions are preferred.
