Cape honeysuckle

Tecomaria capensis

Cape honeysuckle (Tecomaria capensis, Bignoniaceae) is a vigorous, evergreen scrambling shrub from southern and south-central Africa, valued for tubular orange-to-apricot flowers borne erratically across much of the year. It reaches about 6.6 to 9.8 feet tall and wide as a free-standing shrub, or can be trained much taller on a trellis or wall, and is widely used for informal hedging and as a hot-color border or container plant. It is frost-tender (RHS H1C; roughly USDA 9b-11) - in cooler climates it is grown under glass or as a summer container plant and overwintered indoors. In frost-free, mild climates it can become weedy: it has naturalised and is treated as invasive in parts of Australia and on islands such as the Azores, so site it where suckering and self-layering can be managed. It is not a recognised edible and is not flagged as notably toxic, though several plant parts feature in traditional southern-African medicine; treat it as ornamental rather than for consumption. Note the accepted binomial here is Tecomaria capensis (POWO/GBIF); the widely-seen Tecoma capensis is a synonym.

In its native southern-African range the long tubular flowers are mainly pollinated by nectar-feeding sunbirds, with honeybees and butterflies also visiting; in cultivation elsewhere it is grown chiefly as an ornamental nectar plant rather than for fruit/seed set.

Hydrangea serrata

Mountain hydrangea

Mountain hydrangea is a compact, deciduous flowering shrub native to the mountainous regions of Japan and Korea, where it grows in cool, moist, partly shaded conditions - and that cool mountain origin is the honest catch. Hardy through USDA Zone 6 when dormant, the plant breaks dormancy early and its new spring growth is reliably vulnerable to late frosts; a single late freeze in April can destroy an entire season's bloom on wood that would otherwise flower in midsummer. It is smaller and more refined than bigleaf hydrangea, with serrated leaves and distinctive lacecap flowerheads in blue or pink depending on soil pH, making it a graceful focal point for partly shaded borders where consistent moisture can be maintained.

Nandina domestica

Heavenly bamboo

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.

Spiraea thunbergii

Thunberg Spirea

Thunberg spirea is a fine-textured, arching deciduous shrub native to East China and Japan, among the earliest spireas to flower - its slender stems are smothered in clusters of small white flowers in late winter to early spring, often before the narrow willow-like leaves fully emerge. In a sunny, well-drained border it is tough, fast to establish, and carries RHS Award of Garden Merit status. The honest catch is allelopathy: the roots and litter release cis-cinnamoyl glucosides and cis-cinnamic acid, compounds that measurably suppress germination and growth of nearby plants - avoid planting into a densely seeded wildflower mix or close-spacing with shallow-rooted perennials.

Viburnum plicatum

Doublefile viburnum

Doublefile viburnum is a deciduous shrub native to China, Korea, Japan, and Taiwan, grown for its spectacular tiered, horizontal branching draped in flat lacecap flower heads in late spring. It earns its place as a four-season focal point - white flowers in May, blue-black drupes in late summer, and often vivid red-purple autumn colour - but the honest catch is its sheer footprint: mature plants can spread 13 to 16 feet wide with rigidly horizontal branches that resent hard pruning, and the fruit is not edible.

Camellia sasanqua

Sasanqua camellia

Sasanqua camellia is an evergreen shrub native to the forests of southern Japan - Kyushu, Shikoku, and the Ryukyu Islands - where it grows on forest margins and hillsides. In gardens it is prized as the earliest-flowering camellia, bearing fragrant blooms from September through January when almost nothing else is in flower, and it tolerates more sun and drought than its cousin Camellia japonica. The honest catch is cold hardiness: open flowers are blackened by hard frost, and the plant itself is reliably hardy only from zone 7a south, making it unsuitable for much of the northeastern and midwestern United States without meaningful shelter.

Shrubby scorpion vetch

Coronilla valentina is a compact, evergreen Mediterranean shrub in the legume family (Fabaceae), with a native range spanning the Mediterranean Basin from Portugal and Spain through Italy, the NW Balkans and Greece to the Aegean and Turkey, and south across northwest Africa to Libya. In a warm, sheltered garden spot it rewards with prolific, intensely honey-scented yellow flowers from late winter into summer and handsome glaucous foliage year-round. The honest catch is cold-hardiness: RHS rates it H4 (hardy to about 14°F), so it is borderline at the cold edge of USDA zone 7 and is liable to be cut to the ground or killed outright in a hard freeze, demanding a sheltered south- or west-facing wall in colder gardens - and the whole plant is toxic to humans and livestock.

Chinese Fringe Flower

Loropetalum chinense is an evergreen shrub native to woodlands and thickets across southern China, Japan, Taiwan, and adjacent parts of Southeast Asia, valued in gardens for its distinctive ribbon-like flowers and, in the popular purple-leaved forms, year-round burgundy foliage. It thrives in zones 7-9 as a bold structural shrub or hedging plant, blooming most heavily in late winter to early spring. The honest catch is its absolute dependence on acidic soil: even slightly alkaline pH triggers iron chlorosis, and in the Southeastern US a bacterial crown gall disease can cause rapid branch dieback and plant death, making site preparation and soil testing non-negotiable before planting.

Glossy abelia is a garden hybrid shrub first raised in 1886 at the Rovelli nursery in Pallanza (Verbania) on Lake Maggiore, Italy, by crossing the Chinese species Abelia chinensis and A. uniflora; it has no wild native range. Its chief assets are a very long, fragrant late-season bloom - white to blush-pink bells from mid-summer well into autumn, when few other shrubs flower - combined with glossy, semi-evergreen foliage and a tidy arching habit that suits mixed borders and foundation planting. The honest catch is marginal hardiness: in zones 6 and colder the soft stem tips routinely die back in hard winters, demanding annual remedial pruning and a sheltered site, and the shrub can look ratty after a cold snap before fresh growth breaks in spring.
