#ornamental tree
- Cootamundra wattle — A remarkable species of small to medium-sized ornamental tree, native to a restricted area in New South Wales, Australia, but widely naturalized in Mediterranean and temperate regions worldwide. The plant is highly prized in landscaping due to its evergreen, bipinnate foliage with a spectacular bluish-green or silvery (glaucous) tint, and its early late-winter flowering, when the canopy becomes completely covered in dense clusters of fluffy, intensely fragrant, bright golden-yellow globular flowers.
- Aesculus pavia — Scientific name of the red buckeye, a small deciduous tree or shrub species native to the southeastern United States, structurally recognized by its erect inflorescences with bright red tubular flowers and smooth, spineless capsules containing seeds rich in toxic saponins. It is widely cultivated as an ornamental plant in parks and gardens due to the vibrant color of its spring blooms and its ability to attract hummingbirds.
- Amelanchier arborea — A species of small tree or large shrub in the genus Amelanchier, Rosaceae family, native to eastern North America, commonly known as the 'downy serviceberry' or 'common serviceberry'. This plant reaches larger dimensions than other related species and is structurally distinguished by smooth, gray bark, young leaves covered in fine downy pubescence, and pendulous clusters of white flowers that bloom in early spring before the leaves fully unfold.
- Amelanchier laevis — A species of small tree or deciduous shrub in the genus Amelanchier, Rosaceae family, native to eastern North America, popularly known as the 'smooth serviceberry' or 'allegheny serviceberry'. It is structurally distinguished from other species by its leaves being entirely hairless (smooth, glabrous) even when young, expanding with a spectacular bronze-purple tinge that complements the drooping clusters of snow-white flowers.
