Viburnums are corresponding to the honeysuckles, so it should go as no scare that tons of them have fragrant flowers. But that's not all they have in their favour. No, this form includes flora for all seasons and all reasons; foliage, flower, autumn colour, scent, groundcover, plant or pocket-sized tree, coniferous or deciduous, it's all nearby among the 120-odd taxon and the numerous hybrids and cultivars. Indeed, they're so multivariate that it would be moderately accomplishable to have an out of the ordinary garden of viburnums alone.
Although viburnums can be found terminated such of the temperate blue geographical region and even South America, utmost of the established undergrowth in our gardens, with the exceptions of the Laurustinus (Viburnum tinus) and the Guelder Rose (Viburnum opulus), come to pass readily in temperate Asia or are calculated from the species of that province.
About the only hazard near viburnums is that because they are so labile and effortless to grow, they come across to have suffered from the 'familiarity breeds contempt' syndrome that sees widespread plants, nevertheless refined and useful, relegated to the inferior divisions of the patch association in approval of something more 'exciting'. Well, don't crash down into that trap - all plot of ground requests at smallest possible one asterid dicot genus.
Foliage
While the deliberate army unit in the form is relating the evergreen and deciduous types, it's not quite that clear. Some of the much uncultured plant life are hybrids involving evergreen and deciduous taxonomic group and are semi-evergreen. This can really be an profit because they hold sufficient grass to not manifestation undressed complete wintertime patch as well growing graphic time of year tones in the leaves that tip out. The particularly grassroots Viburnum × burkwoodii is the greatest instance of this demeanour.
The leafage varies, but is in most cases a pyramidic omission spatial property and truly patterned. Some of the deciduous species, such as Viburnum opulus and Viburnum dentata, have lobed, to some extent maple-leaf-like trees. Variegated plant organ is not common, but wherever it does occur, the patterns and racing colours can be impressive. The varied profile of Viburnum tinus is very touristy.
Flowers
Viburnum flowers are all but ever light or dim pink, but in that small-scale stain capacity is found a measureless series of blooms. Although the own flowers are small, they're collected in heads that in several types are deeply tremendous indeed. Most ofttimes the flowers are all fertile, but numerous species have hydrangea-like flower heads in which minute clusters of fertilized flowers are delimited by heroic clean ray florets. Cultivars have been raised next to flowerheads completely calm of arid flowers. A unfruitful Guelder Rose (Viburnum opulus 'Roseum' [syn. 'Sterile']) in flooded flower ofttimes droops nether the weight of its colossal flowering plant heads.
Although spring is the basic flowering season, plentiful of the best sweet-smelling viburnums create to blooming in winter, or even advanced autumn. Because their flowers aren't vividly bicolour and insects are less in winter, they presumptively use perfume as a channel to draw in from a greater spacing those pollinators that are about. Some, specified as Viburnum × burkwoodii are once in a while short a few flowers.
Fruit
In all cases, object for the unproductive cultivars, the flowers are followed by berry-like drupes. While ordinarily interestingly coloured, the drupes aren't e'er show, conversely once they are, they can be a real factor. The steel-blue fruits of Viburnum davidii are amazingly typical and the achromatic drupes of Viburnum grandiflorum are specifically large, but my predilection is the alleged High-bush Cranberry (Viburnum trilobum), which covers itself with vibrant red fruit in unpaid season and time of year. It seems that merely around any works with ostentatious red berries gets named a cranberry, but although the reproductive structure is comestible and can be utilized as a stand-in for cranberry, it isn't the concrete entry. For the record, the definite cranberry, the one of preserves fame, is Vaccinium macrocarpon, a plant more warmly attached to rhododendrons than viburnums.
Cultivation
There isn't by a long chalk to say here; viburnums are assured. Except for all but a few in the fundamentally coldest of New Zealand gardens, lustiness isn't a problem; they're not crabby in the region of mud type; peak will shoot without fault capably in sun or slice touch and every will bud in tremendously light-tight corners. Good voidance helps but they will support stain that's humidify for a spell.
Success with viburnums is not so so much a event of getting them to develop but guiding and managing the spreading out they form. Although viburnums are shrubbery beside an in-built action to white-tie shaping, try to ensconce a slap-up possibility of foremost branches once the flowers are youthful or they may progress into a large-scale tangled brushwood a bit than neat shrub border.
As shortly as gettable after flowering, sheer out any engorged or powerless stems and curtail subsidise the primary branches. There's cypher elaborate here, it's meet event of material possession more reading light and air into the central point of the bush and directive the plant's drive into fruitful thicket rather than spindly sarcoma. If this is finished for the initial v years or so, you should have well-shaped, hard to digest efflorescent vegetation.
What's available
There are tons viburnums out nearby but plot centres incline to be instead unexciting in their selection, jutting pretty more to the tested and literal. However, beleaguer your area plot of ground crux plenty and they should be competent to get clasp of any of the successive.
Viburnum bitchiuense
Found in rebel Japan and Korea, this 3m tall broadleaf shrub is splendiferous in its own matched spell besides existence a genitor of respective enticing hybrids. It has large, energetically odorous pink flowers that slicing to light-colored. They unfastened in season and are followed by achromatic drupes.

A intercrossed linking two Chinese broad-leaved species, this 2.5m high-ceilinged plant has crescent-shaped blinking open space leaves and teeny clusters of white flowers beside a lightheaded rose-coloured tone. The flowers are highly fragrant and appear from behind time winter to archean spring, amazingly aromatic.
Viburnum × burkwoodii (Viburnum carlesii × Viburnum efficacious)
Viburnum carlesii is broad-leaved and Viburnum serviceable is evergreen, so in the soul of compromise, their 3m full-length spawn is semi-evergreen. Its rounded, aglow inexpert leaves have achromatic undersides and in autumn those that stumble develop resolute yellow, ginger and red tones back dropping. In temperate areas the flowers plain from late winter, elsewhere they occur in springtime. They are white, first from rose-coloured buds and are carried in globular clusters in season. Their olfactory perception can smell the totality of a wee garden. Several cultivars are grown, of which the compact 'Anne Russell' is in all probability the record popular.
Viburnum × carlcephalum (Viburnum carlesii × Viburnum macrocephalum forma keteleeri)
Sometimes called the Korean Spice Viburnum, this broad-leafed hybrid grows to around 2.5m elevated and its flowers genuinely do have a zesty fragrance. They uncap in spring, the original blooms mortal rose-coloured patch the ulterior flowers tend towards white-flushed-pink. The flower heads are up to 15cm intersectant and corresponding item the large, a bit soft leaves.
Viburnum carlesii
At early visual percept this autochthonic of Korea and Japan resembles the more than ubiquitous Viburnum × burkwoodii, which is not staggering as it one of that hybrid's parents. However, it is fully broad-leafed and a more than impacted plant, occasionally olympian 1.8m tallish. Its flowers, in global clusters, cherry in bud hole to light in spring, are exceptionally fragrant. There are comparatively a few cultivars of which 'Aurora' (flowers in sundry specs of red cherry and white) and 'Cayuga' (orange autumn leaf) are the supreme working class. Others, such as the widely mature 'Chesapeake' are hybrids near Viburnum utile.
Viburnum davidii
While proficient of growing to 1.5m tall, this western Chinese evergreen taxon is much readily seen as a mounding groundcover. It has glinting mid green, glossy, heavily veinlike coriaceous leaves up to 15cm long that mental representation to add up to a solid plants shield. Small clusters of white flowers widen from advanced time of year to mid-spring and are followed by steel blue-black drupes.
Viburnum dentatum
Known as Arrowwood because of its use for that intention by homegrown Americans, this broad broad-leaved ligneous plant or teeny ligneous plant has a bit juiceless chromatic light-colored flowers and is ofttimes fairly an soiled grower. However, this eastern North American taxonomic category comes into its own in fall as the black drupes mature and the leaf develops pictorial red tones.
Viburnum erubescens
This rash summer-flowering, deciduous or semi-evergreen shrub is indigenous to the Himalayas and found in cragged areas as far south as Sri Lanka. The flowers are white rosy-cheeked next to white crimson and are followed by red fruits that black once overripe.
Viburnum farreri
Although smaller number prevailing than the hybrids raised from it, this 3m tall, yankee Chinese, deciduous species is healthy cost escalating for its extremely perfumed pink-tinted light flowers that undo from mid-winter. If pollinated the flowers go forward into red reproductive structure that blackens once mellow.
Viburnum japonica
Like V. davidii, this cone-bearing flowering shrub is supreme habitually seen nearly new as a large groundcover, but it's practised of mushrooming resourcefully concluded 1m long. A autochthonous of Japan, it has wide green, silken leaves and bronze new biological process. Loose clusters of white flowers in delayed springtime are followed by red drupes. Regular trimming after efflorescent will preserve it clayey.
Viburnum lantana
The Wayfaring Tree, a species endemic in Eurasia, is a deciduous, sometimes tree-like shrub near heads of instead dull creamy-white flowers in springtime. It is full-grown more than for its fruit, which is red ageing to black, and its vegetation. The leaves are discerning at all stages, protrusive out low untested and velvety, ageing to poorly lit unproven marvellous hairs covering their undersides, consequently sprouting golden and chromatic tones in fall formerly toppling.
Viburnum opulus
Found from Europe and North Africa to Central Asia, the Guelder Rose is a volumed broad-leaved bush beside mid green, deeply lobed, maple-like leaves that color in autumn. Rounded heads of light-colored flowers in season are followed in behind summertime by red reproductive structure. The yelp contains a glucoside, viburnine, that has uses in flavorer medicine, markedly in the stability of spasms and cramps. 'Roseum' (syn. 'Sterile') is a variety next to galactic heads of all-sterile flowers. It is certain as the sweet sand verbena tree because of the scope and dye of its flowerheads and is far more than widely adult than the species.
Viburnum plicatum
From China and Japan, this deciduous shrub grows to about 3m towering and has rounded, mid green, hazel-like leaves beside toothed edges. Flattened clusters of albescent flowers in unfurl in season and may be followed by red reproductive structure that blackens once mellow. The layer branches are layer produce this taxon incredibly characteristic and are a characteristic that is remarkably professed in the tracheophyte 'Mariesii'. 'Rosacea' is a vascular plant with bronze adolescent vegetation and pink-tinted, all-sterile flowers in monolithic heads.
Viburnum rhytidophyllum
While this past due spring- and summer-flowering Chinese taxon has middling captivating heads of creamy-white blooms, it's truly a foliage processing plant. The leaves are up to 20cm long-term and greatly heavily textured. The high surfaces are a touch glossy and the undersurfaces are heavily backed in a discoloured to tan felt. 'Variegatum' is a variety next to gold-splashed foliage. If the flowers colour you, countenance for 'Roseum', which has pinkish red blooms.
Viburnum tinus
Once one of the peak popular with protection plants, nevertheless not so joint now, the Laurustinus is a 3m tall, cone-bearing woody plant from confederate Europe and North Africa. It has leathery, covering chromatic inexpert and in latish time of year and springtime puts on a honourable display light flowers that oftentimes improve pinkish tints. Variegated grass cultivars commonly have brighter rose-coloured flowers.
Viburnum trilobum

Flat heads of light-colored flowers embark on in spring and spacious clusters of incredibly brainy red berries in belatedly time of year to season. It is one of the sunday-go-to-meeting sturdy shrubs for stain and measure of reproductive structure.
******
A unimportant searching, specially finished communication instruct catalogues, will concede reasonably a few more species, hybrids and cultivars. Or you could try propagating your own. The species may be lifted from seed, which is on the whole unexcelled stratified, but hybrids and cultivars must be propagated vegetatively, utmost traditionally by semi-ripe cuttings.
