Habit

Massive, broadly spreading deciduous tree with a domed, asymmetrical crown; stout ascending branches and a thick, deeply furrowed grey-brown trunk; open-grown specimens develop a wide, irregular silhouette wider than tall at maturity.

Care tips

•

Plant the smallest affordable whip (24 to 35 inches bare-root) in late autumn or early spring - a small start establishes a larger root system faster than a big containerised tree and the results equalise within 10 years.

•

Choose the permanent site with great care before planting: mature roots extend well beyond the canopy drip-line, heave paving, and can damage foundations and drains - the RHS recommends planting no closer than 66 feet from buildings for large-growing oaks.

•

Do not over-stake: a single short stake for the first 2 years is enough. Trees that flex in wind develop stronger, more tapered trunks. Remove the stake as soon as the tree stands unsupported.

Lifecycle

Planting

Plant bare-root trees November–March, or container-grown specimens any time the ground is workable; smaller whips (24 to 35 inches) establish more reliably than large transplants and will often overtake them within a decade. Choose open ground away from buildings, drains, and paving - a minimum 49 feet from any structure is a practical starting rule.

Transplanting

Poorly tolerant of transplanting once established beyond sapling stage; root prune container stock before purchase. Bare-root whips transplant most successfully in the dormant season. Never attempt to move a field-grown specimen larger than 6.6 feet without specialist equipment.

Early growth

Growth is slow in the first 3–5 years as the root system establishes; expect 8 to 16 inches of height gain per year in good conditions once settled. Stake only lightly and remove stakes after 2 years to encourage trunk taper and wind-firmness.

Maturity

Reaches substantial garden size (33 to 49 feet) in 40–60 years; full biological maturity with maximum biodiversity value takes 200–400 years. The species routinely lives 500 years and exceptional specimens exceed 1,000 years (Wikipedia).

Propagation

Propagated by seed (acorns): sow fresh in autumn 0.8 to 1.2 inches deep in free-draining compost outdoors or in a cold frame; stratification not required as seeds are not dormant. Germination is epigeal. Named cultivars are grafted onto Q. robur rootstock.

Tilia americana

American basswood

A medium-to-large native shade tree of central and eastern North America, reaching 50 to 80 feet with an ovate-rounded crown and large, asymmetric heart-shaped leaves. In June it carries pale-yellow, intensely fragrant flowers on pendulous cymes - each cluster hung from a distinctive strap-like leafy bract - that ripen into pea-sized nutlets. The fragrant June bloom is a premier nectar source: Missouri Botanical Garden lists it as attracting bees and butterflies, and the Lady Bird Johnson Wildflower Center flags it as having special value to both native and honey bees.

The only native U.S. holly with both spiny green leaves and bright red berries - an upright, pyramidal, broadleaf evergreen tree that slowly matures to 15 to 30 feet in cultivation (to 50 feet in the wild). Thick, leathery, deep green leaves bear spiny marginal teeth, and pollinated female trees carry showy red-to-orange drupes that ripen in fall and persist through winter as bird food. This is the classic "Christmas holly" of wreaths and decorations.

A tough, medium-sized native tree of the eastern and midwestern United States, grown as much for its showy edible orange fruit as for its distinctive thick, dark gray bark broken into rectangular blocks. Small urn-shaped white-to-greenish-yellow flowers open in May and June, and the sweet fruit ripens after frost. Largely dioecious - a female tree needs a male pollinizer nearby to set fruit - and notably drought- and walnut-tolerant once established.

The largest native cherry of eastern North America - a medium-to-large deciduous shade tree that hangs elongated racemes of small white flowers in spring, then ripens drooping strings of pea-sized fruit from red to near-black in late summer. The fragrant white bloom feeds bees while the fruit is eaten by 33 species of birds and many mammals; it is also a workhorse larval host, supporting the Eastern Tiger Swallowtail and a string of giant silk and sphinx moths. Every part except the ripe fruit is cyanide-bearing and toxic.

Common hawthorn is a deciduous, thorny small tree or large shrub native to Europe, northwestern Africa, and western Asia, where it has been used for centuries as stock-proof hedging and valued for its May blossom and autumn haws. In the garden it earns its keep as a tough wildlife powerhouse - a single mature tree can support hundreds of invertebrate species, and the haw crop sustains thrushes and waxwings through winter (Wikipedia). The honest catch is the thorns: they are genuinely sharp (up to 0.5 inches), making pruning painful and placing it off-limits near paths and play areas; the tree is also considered invasive in parts of the Pacific Northwest, Australia, and New Zealand where it outcompetes native scrub.

Date plum (Diospyros lotus) is a deciduous tree native from northeastern and south-central Turkey east through Iran, the Himalayas, and Central Asia to China and Korea, with a history of cultivation reaching back to antiquity - possibly the "lotus" of Homer's Odyssey. In gardens it offers glossy foliage, small greenish-cream flowers in summer, and ornamental fruit ripening to yellow then blue-black. The honest catch is twofold: the tree is dioecious, so a male is needed near a female for a proper seeded crop (a lone female sets only sparse, often seedless fruit), and the fruit is intensely astringent until fully ripe or frost-softened, so it is messy and unpalatable if picked early.

English oak (Quercus robur) is a long-lived, massive deciduous tree native across most of Europe and into western Asia, prized as one of the most wildlife-rich trees in the temperate world - supporting approximately 2,300 associated species in the UK alone (Wikipedia). It makes an unrivalled long-term specimen or parkland focal point in large gardens, with deeply lobed leaves, pendulous catkins in spring, and heavy acorn crops in autumn. The honest catch is scale and patience: this tree will ultimately reach 66 to 131 feet tall with an even wider spreading crown and a root system that extends far beyond the canopy, making it entirely unsuitable for small gardens, pavement planting, or anywhere near buildings or drains; acorns and young leaves contain gallotannins toxic to horses, cattle, and other livestock in quantity.
