Heavenly bamboo is an evergreen (semi-deciduous in cold winters) shrub native to eastern Asia from the Himalayan foothills to Japan, valued for striking year-round foliage that flushes pink-red in spring, turns green in summer, and blazes red-purple in autumn and winter, plus panicles of white summer flowers and persistent bright-red berries. It is adaptable, drought-tolerant once established, and undemanding in most soils from full sun to part shade. The honest catch is dual: all plant parts — especially the berries — contain cyanogenic compounds, and excessive consumption of the berries can be lethal to cedar waxwings and is toxic to cats and livestock, making it a poor choice wherever birds congregate to feed on winter fruit; and in the southeastern United States it is classified invasive (Florida Category I) and is best replaced with a non-invasive native alternative.

Japanese holly is a dense, small-leaved evergreen shrub native to Japan, Korea, eastern China, and adjacent regions of eastern Asia, widely grown as a boxwood substitute for formal hedging and topiary. It tolerates heavy shearing well and thrives in acidic soils in a range spanning USDA zones 5b-8b. The honest catch is twofold: the glossy black berries are toxic to humans and pets (a genus-wide trait of Ilex), and the species is listed as invasive in parts of the eastern United States, where bird-dispersed seedlings colonise native woodland edges.

A dense, conical-to-narrow-pyramidal evergreen tree native to eastern and central North America, prized as a screening and foundation conifer. Flat, fan-like sprays of scale-like, aromatic yellow-green foliage clothe the tree from the ground up, and red-brown bark exfoliates on mature trunks. Wild trees can reach 40-60 feet but cultivated plants typically stay near 20-30 feet; small urn-shaped cones and dense evergreen cover make it valuable food and shelter for birds.

English yew (Taxus baccata) is a slow-growing, exceptionally long-lived evergreen conifer native across Europe (except Iceland), the Caucasus, Turkey eastward to northern Iran, and Morocco and Algeria in North Africa, valued for centuries as the definitive topiary and formal hedge tree. Its dense, dark-green needle foliage tolerates extreme shade and hard clipping, making it the premier structural plant for sculptured gardens. The honest catch is severe toxicity: nearly every part of the plant — needles, bark, seeds — contains cardiotoxic taxine alkaloids with no antidote, posing a lethal risk to humans, livestock, horses, and dogs; only the red fleshy aril is non-toxic, though the enclosed seed is deadly.
