Lion's ear (wild dagga)

Leonotis leonurus
Leonotis leonurus, the lion's ear or wild dagga, is a fast-growing, soft-woody evergreen shrub in the mint family (Lamiaceae) native to South Africa, reaching about 4.9 to 9.8 feet tall with square stems carrying tiered whorls of brilliant orange, tubular two-lipped flowers. In the garden it works as a striking late-season focal shrub or large border plant for hot, dry, full-sun positions and pairs naturally with other South African and Mediterranean-climate planting. It is frost-tender - RHS rates it H2, meaning it tolerates cool conditions down to about 34 to 41°F but is killed by hard freezes - so outside roughly USDA zone 9b–11 it is grown in containers, as a cut-back tender perennial, or under glass. Note that the dried leaves are mildly psychoactive (containing leonurine and labdane diterpenes) and the plant is regulated in some countries, and high-dose animal studies have shown organ toxicity, so it should not be treated as a food or casually ingested. It can also naturalize and become weedy in frost-free Mediterranean climates such as parts of California, Hawaii and Australia.

In its native South African range the orange tubular flowers are primarily bird-pollinated - sunbirds (white-bellied, black, olive, collared and others) are drawn to the curved tubes - with honeybees and butterflies as secondary visitors.

Beauty bush (Kolkwitzia amabilis) - bell-shaped (campanulate) tubular flowers borne in dense clusters along the branch, pale-pink to white corollas with a bright yellow-orange throat marked by orange reticulate veining, abundant simultaneous bloom (flowering branch smothered in flowers) on a leafy deciduous shrub.
Kolkwitzia amabilis
Beauty bush
A large, vigorous, fountain-shaped deciduous shrub that earns its common name in late spring, when its arching stems are smothered in masses of pale-pink, yellow-throated, bell-shaped flowers. Native to China, it is one of the great old-fashioned spring shrubs - spectacular in full bloom, much loved by bees, and offering peeling brown bark for quiet winter interest. It is also genuinely big: expect 6 to 10 feet tall and wide at maturity, so give it room rather than fighting its size with the shears. The form to seek out is the Award-winning "Pink Cloud", which carries a clearer, richer pink than the variable seed-grown species.

A Cape honeysuckle (Tecomaria capensis) shrub with arching evergreen foliage and clusters of slender orange tubular flowers.
Tecomaria capensis
Cape honeysuckle
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.

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.

Ribes sanguineum in bloom in Whatcom County, Washington, showing pendant clusters of deep-pink flowers on bare stems
Ribes sanguineum
Flowering Currant
Flowering currant is a deciduous shrub native to the Pacific coast of western North America, from British Columbia south through Washington and Oregon to coastal California (as far south as Santa Barbara County), with a marginal inland presence in Idaho and a southern outpost on Guadalupe Island, Mexico. Its bold dangling racemes of deep-pink to crimson flowers open in early spring, often before the leaves, making it one of the most conspicuous late-winter shrubs in mild gardens. The honest catch is threefold: it is a confirmed alternate host of white pine blister rust (a serious pathogen of five-needled pines), its blue-black berries are edible but notably insipid, and it has become an established invasive weed in New Zealand (where it forms dense stands excluding native species) and is a more minor, localized weed in Tasmania.

Viburnum opulus
Guelder rose
A large deciduous European-native shrub grown for a three-season show: maple-like lobed leaves that color well in autumn, flat white lacecap flower clusters in late spring, and heavy drooping bunches of translucent red berries that hang on into winter. Each flower head is a showy ring of large sterile outer florets surrounding a fertile center, giving the lacecap its distinctive look. It is one of the best all-round wildlife shrubs you can plant - the open flowers feed hoverflies and bees, and the red fruit feeds birds through the cold months - and it tolerates wet soil, making it a natural choice for hedgerows, damp corners, and wild gardens. Two honest cautions go with it: the raw berries are mildly toxic to people, and this is the European guelder rose, not the North American cranberrybush.

Viburnum carlesii in full bloom showing dense rounded clusters of pale pink and white fragrant flowers against green foliage
Viburnum carlesii
Koreanspice viburnum
Viburnum carlesii is a slow-growing deciduous shrub native to Korea, the Japanese island of Tsushima, and adjacent parts of southeastern China, prized above almost all shrubs for its intoxicatingly spiced spring fragrance - dense, rounded clusters of pink buds open to white flowers with a cinnamon-clove perfume that carries across an entire garden. It settles into a tidy, broadly rounded habit of 4 to 6 feet and adds a secondary season of interest through red fruits that ripen to bluish-black in autumn, taken readily by birds. The honest catch is the rootstock: most retail plants are grafted onto Viburnum lantana, which throws vigorous suckers from below the graft union; if those suckers are not removed promptly, the coarser, unscented rootstock will eventually crowd out the named cultivar entirely.
