Armand clematis is a vigorous evergreen climbing shrub native to much of China (except the north and extreme south) and northern Myanmar, grown for its profusion of almond-scented, star-shaped white flowers in early spring (March-April) on the previous season's wood. It excels as a structure-covering climber on sheltered walls, pergolas, and fences, providing year-round glossy, deep-green foliage. The honest catch is its rampant vigor: in a favored site it can overwhelm host structures within a few years, sheds masses of dead leaves through the year (a persistent litter problem), and all parts are toxic to cats, dogs, and horses (and the sap irritates skin) - and it is only reliably hardy to about USDA zone 7b with the shelter of a warm wall, making it a borderline plant anywhere colder.

Care tips

•

Give it a big, strong support and plenty of room: NC State says it can reach upwards of 40 feet, and Trees and Shrubs Online warns to keep it away from gutters and out from under the eaves.

•

Plant it in the sunniest, most sheltered spot you have; the RHS and Plants For A Future both say it flowers best on a warm, sunny wall.

•

Prune lightly and only right after flowering. The flowers come on stems two or three years old, so cutting everything back each year removes the next spring bloom; instead, take out a few of the oldest stems at the base every few years, as Trees and Shrubs Online advises.

Lifecycle

Planting

Plant it in full sun in the warmest, most sheltered spot available. NC State says it grows in full sun or partial shade in moist but well-draining, acidic to neutral loam with good air circulation. The RHS says fertile, humus-rich, moist but well-drained soil in full sun on a sheltered south- or west-facing wall, in chalk, clay, loam or sand of any pH, and Plants For A Future says it needs a very sunny position to flower well. Before planting, put up a support strong enough for a very large climber; Trees and Shrubs Online warns that it needs a lot of space and must be kept away from gutters and out from under the eaves.

Transplanting

None of the sources gives advice on moving an established plant. Plants For A Future says rooted suckers can be dug in the dormant season and planted straight into their permanent positions.

Early growth

Tie the long new shoots to their support as they grow; NC State says to give the branches sturdy support. The RHS advises a mulch of well-rotted organic matter in late winter or early spring, and a general rose or shrub fertiliser in early spring and again in early summer for the best flowering. Do not expect much bloom for the first few years, and do not cut the young stems back hard, because they carry the flowers in their second and third years.

Maturity

The sources differ widely on its size. NC State gives 15 to 40 feet high and 6 to 10 feet wide, and Trees and Shrubs Online up to 40 feet. The RHS gives 13 to 26 feet high and 8.2 to 13.1 feet across for the species and 26 to 39 feet for the yellow form, while the Flora of China and Wikipedia give 20 feet and Plants For A Future 33 feet by 39 feet. For pruning, NC State says to remove dead wood and otherwise prune only to reduce its size, soon after it blooms; the RHS puts it in its rambling-rose pruning group, pruned right after flowering in late spring. Trees and Shrubs Online says yearly pruning is unnecessary, but the older stems should be cut out cleanly every so often after flowering. NC State says black spot and mildew are less of a problem than on most roses. The RHS lists aphids, rose leafhopper, red spider mite, scale insects, caterpillars and sawflies as possible pests, deer and rabbits as possible damage, and black spot, rust, powdery mildew, dieback, replant disease and sometimes honey fungus as possible diseases.

Propagation

The RHS gives softwood cuttings in early to mid spring, hardwood cuttings in late summer to autumn and chip budding in summer; it says species roses can be raised from seed, which needs stratification and may take two seasons to germinate. Plants For A Future adds half-ripe cuttings with a heel in July in a shaded frame, cuttings 8 to 10 inches long of mature wood in early autumn, suckers dug in the dormant season, and layering, which takes about a year.

Native range

Climate notes

•

NC State Extension lists Lady Banks' rose for USDA hardiness zones 6 to 10, the range used here, and says it is evergreen in zones 8 to 10. Plants For A Future gives 6 to 9 and calls it hardy to UK zone 7. The RHS rates it H5, hardy through most of the UK in severe winters (5°F to 14°F), but says it does best on a warm, sheltered wall and is liable to frost damage elsewhere. No second organisation states the same range as NC State, so the zones rest on NC State alone.

•

Treat it as a warm-climate rose. Trees and Shrubs Online says it is too fond of the sun to thrive in the cooler, rainier parts of the British Isles and needs the protection of a sunny wall, and that the double yellow 'Lutea' is the hardiest form. Plants For A Future says it grows best in the southeast of Britain, and NC State lists it for the Coastal and Piedmont regions of North Carolina, not the mountains. Wikipedia notes that cold weather can delay flowering. Whether it keeps its leaves depends on the winter: NC State calls it evergreen in zones 8 to 10, the RHS calls the species semi-evergreen, and Plants For A Future calls it deciduous.

The native range here is taken from Kew's World Checklist of Vascular Plants (WCVP), the dataset POWO publishes: south-central, north-central and southeastern China. The Flora of China records it wild in thickets, scrub, valleys, stream sides and roadsides at 1,640 to 7,218 feet in Gansu, Guizhou, Henan, Hubei, Jiangsu, Sichuan and Yunnan, and widely cultivated across China.

•

WCVP records it as introduced in Assam, India, the western Himalaya, Pakistan, Uzbekistan, Korea and Spain, and Plants For A Future says it has naturalised in Austria and Germany. None of the sources lists it as invasive: Plants For A Future gives it no weed potential, and the California Invasive Plant Council includes Lady Banks' rose among its alternative plants, the garden plants it suggests in place of invasive ones.

Rose rosette disease threatens roses in eastern North America. The USDA Forest Service FEIS review of multiflora rose says the disease, carried by a tiny eriophyid mite, was first found on ornamental roses and is spreading through the eastern United States, where the highly susceptible multiflora rose is common. None of the sources for this species says how susceptible Lady Banks' rose is.

Clematis armandii

Armand clematis

Brazilian jasmine is an evergreen, woody twining vine endemic to the state of Rio de Janeiro in southeastern Brazil, and one of the species from which many of the garden mandevilla hybrids sold for patios, porches, and hanging baskets have been developed. Despite the name it is not a true jasmine: it belongs to the dogbane family (Apocynaceae), and its flowers are funnel-shaped trumpets 2 to 3 inches across, pink-red in the species and red, pink, white, or cream in its many cultivars, carried over a long season from spring into autumn. Its leaves are thick, leathery, and glossy dark green, to about 2 inches long, and it builds large starchy tuberous roots that help it ride out dry spells. It was first described as Dipladenia sanderi, and its garden forms are still generally sold as 'Dipladenia'. It is frost-tender: a frost kills it, so it lives outdoors year-round only in USDA zones 10a-11b, the range published for mandevillas, and is grown as a summer annual or an overwintered container plant everywhere colder. Its milky sap irritates skin and may be toxic if swallowed.

A small native tree with white spring flowers, edible summer berries, and copper to red fall color.

Chocolate vine is a vigorous, twining woody climber native to China, Japan, and Korea, producing clusters of spice-scented purple-maroon flowers in spring and large sausage-shaped fruits in autumn. It adapts readily to most well-drained soils in sun or part-shade and covers structures fast, making it a striking focal-point plant for walls, fences, and pergolas. The honest catch is its invasive potential: it smothers native shrubs and trees by blocking sunlight and is listed as invasive across much of the US East Coast and the Pacific Northwest, so it must not be planted where it can escape into natural areas, and annual hard pruning is essential to keep it under control.

English holly is a slow-growing evergreen shrub or small tree native to western and southern Europe, northwest Africa, and southwest Asia, prized for its glossy spiny foliage and brilliant red winter berries. It tolerates shade, tolerates clay and acidic soils, and is remarkably long-lived, making it a stalwart structural plant for hedging and screening. The honest catch is its dioecy: you need at least one male plant nearby for female plants to berry, and those berries - the plant's most celebrated feature - are toxic to humans and pets, so any planting within reach of children requires clear awareness. In the Pacific Northwest and parts of coastal western North America it has proven seriously invasive, outcompeting native forest understory; gardeners in those regions should choose a sterile cultivar or a native substitute.

European honeysuckle is a vigorous deciduous twining climber native across much of Europe, North Africa, Turkey, and the Caucasus, valued for its intensely night-scented cream-and-pink flowers in summer and the wildlife value of its red autumn berries. In gardens it is a reliable, long-lived focal point for fences, pergolas, and trellises where its base can be kept cool and shaded. The honest catch is the toxicity of the berries: they contain saponins and are emetic, making the plant a hazard wherever small children or dogs have unsupervised access, so site it accordingly.
