Yellow jasmine - Jasminum nudiflorum


Yellow jasmine


We are used to thinking of jasmine as a creeper with white, fragrant flowers; in reality the genus jasminum includes dozens of plants, many of which produce lemon-yellow or golden-yellow flowers, and in many cases they are round-shaped shrubs, useful for preparing beautiful flowering hedges. Some of these are very common in Europe, rustic and well adapted to living in our gardens; the most famous is certainly Jasminum nudiflorum.
Jasmine are climbing or shrubby plants belonging to the Oleaceae family. The genus has about 200 species mostly from tropical and subtropical regions from Asia. Those cultivated are, however, at most twenty (even if there are countless varieties and cultivars).
Most of these have white or slightly pink flowers, but bright yellow is also quite common.
Some of these jasmines are already very widespread and known in our country (such as the very popular nudiflorum), others, however, still remain almost exclusive prerogative of the enthusiasts and it would be worth to know them in more depth. They can indeed be a nice alternative for covering vertical spaces, especially in the central-southern regions, where the climate is not an obstacle to their growth.

The Jasmine of St. Joseph



Jasminum nudiflorum is also called Jasmine of St. Joseph because it seems to flourish in particular on the day of St. Joseph, or March 19th. In fact it is a shrub of Asian origin, widespread in Italy for centuries, and cultivated in the garden: the flowering, as the botanical name suggests, takes place with the plant completely stripped of the leaves, at the end of winter, more or less starting from mid-March. This jasmine is easy to grow; it develops in any soil, even stony and not very rich in organic matter; after planting it needs a good watering, to allow the roots to take root, then it is satisfied with the rainfall and does not require great care. The flowering occurs, in fact, between the end of winter and the beginning of spring; later the plant develops small light green leaves; these shrubs are very dense and compact, and generally do not exceed 100-140 cm in height. A quick pruning at the end of flowering helps to keep our jasmine more compact, and to remove any branches that may have been ruined during the cold season. This jasmine does not fear the cold, and prefers sunny locations; if cultivated in an excessively shaded place it tends to bloom little.

Cultivation


It adapts to different exposures and climates, even if the full sun during the winter favors an abundant flowering. Irrigation is not necessary for adult plants in the ground, unless there are long droughts.
Pruning is not essential. We only intervene if we want to contain development, especially in bush-grown specimens. The right time for this operation is spring, after the end of flowering (never instead in autumn). The plant in fact produces buds on the branches produced the previous year.

























































Jasminum humile



Semi-climbing plant, of Asian origin; this jasmine is evergreen, has small oval leaves, and produces large pendulous inflorescences in late summer; the flowers are trumpet-shaped, and are golden yellow in color, intensely scented; flowering lasts for a few weeks.
Plant of easy cultivation, it fears excessive cold, therefore in areas with very harsh winter climate it is advisable to cultivate in pots, so as to be able to move the plant to a sheltered place in the event of intense frosts.
It prefers sunny or semi-shady locations; the waterings will be regular from March to September, always keeping the soil dry between one watering and another. During the winter months we water only if the climate is particularly mild.

Jasminum parkeri


Small slow-growing shrub, from central Asia, evergreen; this jasmine has a very dense and compact habit, it does not fear the cold and is cultivated quietly in the garden, in a very sunny area. It blooms in summer, with small, very fragrant yellow flowers.

Jasminum fruticans



Plant widespread throughout the Mediterranean basin even in the spontaneous state; it seems that this jasmine has Middle Eastern origins, although for centuries it has been widespread in Italy, both in cultivation and in nature. It produces a large, not excessively dense shrub, with semi-woody branches, of green color; it has small oval leaves, which fall during the winter. In summer it produces yellow flowers, double, sometimes delicately scented. It prefers rich soils, even if it adapts without problems even in stony and poorly humiferous soils.
It is planted in full sun; it does not fear the cold.

Jasminum nudiflorum


Jasminum Nudiflorum, also called Jasmine of St. Joseph, is a semi-climbing plant. It has a semi-healthy habit, but can also be easily cultivated as a shrub, leaving it free to grow.
It is a very rustic and vigorous species. Within a few years it can reach 5 meters in height, especially if it has a well exposed wall as a support.
It is much appreciated and widespread throughout our country because it blooms close to the coldest period of the year. In the Center-South it generally opens its buds in November while, in the North, it is necessary to wait until February-March.
It has sturdy and square-sectioned stems, opposite leaves and trifoliate leaves in turn composed of oval, deciduous leaflets. The flowers appear, in the leaf axil, on the bare branches (and from this the Latin name). They are of a beautiful intense yellow, with five star-shaped petals, and measure about 2.5 cm in diameter, arranged along the entire plant.

Jasminum mesnyi


It is a large (up to 4 m high) and vigorous shrub, with sarmentose branches, originating in China. He has a very free bearing. It can be used as an isolated specimen or raised as a climber. Its leaves are trifoliate, divided into lanceolate leaflets up to 7 cm long, of a beautiful glossy dark green. The flowers are solitary, semi-double and almost 5 cm in diameter, with a beautiful bright yellow, but unfortunately without perfume.
Cultivation
It is a semi-rustic shrub. It can therefore be grown outdoors only in the Center-South, near the coasts. If grown with sunny and warm exposure it can become really vigorous and bloom several times during the year. He usually does it around November and, in a favorable climate, continues until at least March.
Once franked it becomes quite autonomous and does not require frequent water interventions (although they help keep the plant in active vegetation). Pruning is not essential except for containment and cleaning.

Jasminum odoratissimum



This jasmine is quite rare in our country. It is native to the island of Madeira and Africa. It behaves like a small creeper or a medium-sized bush. It has dark and shiny leaves, composed of three small leaves, arranged alternately on the branches. Flowering is abundant and very prolonged (from spring to autumn, in favorable climates). The corollas, small, are tubular and terminate in five star-shaped petals, of a beautiful bright yellow. The individual flowers are collected in terminal bunches. They give off a light but very sweet scent.
Cultivation
It is quite sensitive to low temperatures and can only be grown in the ground in southern regions.
During the vegetative period it needs regular irrigations and fertilizations. Pruning is done in autumn or early spring, although it is not strictly necessary.

Jasminum parkeri



Very interesting for cultivation on balconies and terraces or as a ground cover, all over Italy. It is in fact a slow-growing shrub with very small dimensions, originating in northern India. Rarely exceeds 30 cm and easily withstands the rigors of winter.
It flowers abundantly and continuously from March to May. The corollas are light yellow and deliciously scented.
Cultivation
It is a very adaptable shrub. It bears the heat well and also the drought. The administration of water is however welcome and can induce a second flowering. Very suitable for vases, rock gardens or on the front lines of borders. It can also be used for the creation of small hedges.

Jasminum humile revolutum



It is a beautiful shrub, very adaptable and floriferous. Usually it does not exceed 2.5 meters in height for as many in width. It has a rather slow growth (it takes at least 5 years to reach its final size). The branches are slightly arched and give the whole a slightly messy appearance. However, they can be addressed and used as if they were sarmentose. The flowers, of a beautiful intense yellow, gathered in bunches of about 15, appear from May to August.
The leaves are semi-persistent, very firm to the touch. It turned out to be quite rustic, as it usually bears -10 ° C without suffering damage.
Cultivation
To encourage growth and flowering it is good to irrigate and fertilize regularly, from spring to autumn. After the flowering, you can intervene by removing the exhausted corollas and lightly trimming the branches.

Jasminum fruticans


Also known as jasmine in summer (to distinguish it from nudiflorum, similar, but blooming in winter), it is the only one that grows spontaneously in the Mediterranean basin, probably introduced in ancient times from Asia.
The leaves are semi-persistent, of a beautiful glossy dark green. The average height is 150 cm and has an erect shrub bearing, although a little messy. The flowers, produced in abundance between March and April, are arranged in groups at the ends of the stems and are slightly fragrant. In summer they turn into black, toxic berries.
Cultivation
It is rather rustic, as it withstands temperatures down to -10 ° C. It does not require much maintenance and is also suitable for poor and dry soils. We can intervene with light pruning to make the shrub more harmonious and for cleaning from sick or exhausted branches. It can be used as a small climber, as an isolated specimen or for the creation of informal hedges.

Yellow jasmine: Jasminum floridum


Interesting shrub with small dimensions and therefore also suitable for growing in pots, originating in China. The average height is 1.2 meters. The branches have an arched shape and as a whole the plant takes on a beautiful rounded shape. The flowering period is long and runs from May to July. The leaves are shiny, composed and the single leaflets, lanceolate, semi-persistent. The flowers, apical, are in bunches, of a beautiful bright yellow, but they are not perfumed.
Cultivation It is an undemanding plant. Resistant to cold up to -10 ° C and therefore suitable for almost all the Italian territory. He prefers a sunny exposure, but also grows well in partial shade. It adapts to every type of soil, as long as it is well drained. Irrigation is necessary only in the first year after planting, then it proves to be rather autonomous.
Pruning is not strictly necessary. We intervene at the end of flowering to harmonize the forms and eliminate any compromised branches.
