HOW TO GROW AND CARE FOR OUR PLANTS
also known as
These are shrubs of the family ofRubiaceae particularly appreciated for their very showy and fragrant flowers.
Clado: Euroside I
Species: see the paragraph on "Main species"
The kind Bouvardia, known as buvardia, belongs to the family of Rubiaceae and is native to Mexico and South America.
They are small evergreen shrubs, with a bushy character, characterized by drums very branched and thin woody.
The leaves they are deep green in color, with smooth margins, in some tomentose species.
THE flowers they are tubular, usually almost always perfumed, of different color depending on the species and variety and gathered in clusters in the terminal part of the branches.
There are about fifty species among which we remember:
There B. ternifolia it is native to Mexico characterized by leaves covered with a light down, with smooth margins. The flowers gathered in cluster inflorescences in the terminal part of the branches, are red, fragrant and tubular.
There are several varieties among which we remember the variety Whitejoy with white flowers and a very prolonged flowering over time and variety Giantpink with pink flower.
It is known as trumpet plant and it is a fairly rare species.
There B. longiflorait is characterized by very branched and curved stems that bear leaves of a beautiful glossy green color. The flowers are white, fragrant and gathered in cluster inflorescences.
There are numerous varieties among which we remember theB. longiflora var. mary with pink flowers; thereB. longiflora var. president Cleveland with bright red flowers and very fragrant.It blooms from autumn (usually from October to December) and is the most widespread species.
There B. humboldtii by many botanists it is considered a variety of the longiflora characterized by large, white and fragrant flowers. It is not a plant that reaches considerable dimensions not exceeding 70 cm in height.
There B. jasminiflora it has small leaves and white, fragrant flowers. It is a typically winter flowering species.
BOUVARDIA X DOMESTICA
It is a very cultivated hybrid with very prolonged flowering over time from the beginning of summer to the beginning of winter, producing flowers ranging in color from white to pink to red, depending on the variety. It never reaches large dimensions, not exceeding 60-70 cm in height.
TheBouvardia they are not difficult plants to grow.
During the autumn - winter period it should be kept in a position where the light is intense, even in direct sun, with temperatures around 13-15 ° C. During the spring - summer period it always requires a lot of light but not direct sun and temperatures must be around 15-24 ° C.
In midsummer the plant can be taken outdoors, in a bright place but protected from direct sunlight
It is a plant that must be watered so that the soil always remains moist, not soaked.
TYPE OF SOIL - REPOT
It is repotted when the roots have occupied all the space available to them, in spring (usually every 2-3 years).
They are not particularly demanding plants in terms of soil: a good fertile soil will do just fine. Mix a little coarse sand into the soil to help drain the watering water.
It is fertilized from spring and until autumn every two weeks by diluting a good liquid fertilizer in the irrigation water.
Use complete fertilizers, i.e. we have both macro elements such as nitrogen (N), phosphorus (P) and potassium (K) and micro elements such as iron (Fe), manganese (Mn), copper (Cu), zinc (Zn ), boron (B), molybdenum (Mo), all important for a correct and balanced growth of the plant.
Slightly reduce the doses compared to what is indicated in the fertilizer package.
ThereBouvardia it has variable flowering periods depending on the species but generally from summer until late autumn.
At the end of winter, prune vigorously by cutting the branches 8-10 cm from the base of the plant. Very quickly, the new shoots will reappear.
Remember to use a scissors or a knife that is clean and disinfected (preferably with a flame) to avoid infecting the tissues.
Plants propagate for cutting, for seed or for root division.
MULTIPLICATION FOR TALEA
The cuttings can be taken from the stems in early spring, about 8-10 cm long by making an oblique cut (which allows for a greater surface for rooting and avoids the accumulation of water on its surface) and immediately under the node (removing the lower leaves).
Be careful to use a razor blade or a sharp knife to avoid fraying of the fabrics and that it is clean and disinfected (preferably with or with alcohol or bleach).
The terminal part of the cutting is immersed in a rhizogenic powder to facilitate rooting and then the cuttings are placed in a compote formed in equal parts of peat and coarse sand. After making a hole in the soil with a pencil, place the cutting at a depth of about 1.5-2 cm.
Cover the pot with a transparent plastic sheet (or a hooded bag) and place it in the shade and at a temperature around 21 ° C, keeping the soil always slightly moist. Remove the plastic every day to check the soil moisture and eliminate any condensation from the plastic.
When the first shoots begin to appear, it means that the cutting has taken root. At that point the plastic is removed and the plant is moved to a brighter position (not in direct sun). When the seedlings have reached such a size that they can be manipulated, transplant them into the final pot using a soil as indicated in the "repotting" paragraph and treat the plant as if it were an adult.
PARASITES AND DISEASES
The Buvardia they are not plants particularly prone to diseases and if their needs are respected, they grow well and do not have particular problems. Problems are usually caused by poor cultivation techniques.
Falling or rotting leaves or flowers
This symptom is attributable to excessive irrigation.
Remedies: check the roots and remove any rotten roots. For the future, better regulate watering.
Presence of aphids on the plant
It is a plant that can be attacked by aphids or as they are commonly called lice, small yellowish-white mobile insects.
Remedies: it is necessary to intervene with specific antiparasitic products easily available at a good nurseryman.
The name of the genus comes from Charles Bouvard (1572 - 1658), physician of Louis XIII and superintendent of the Jardin Royal in Paris.
The Facultad de Ciencias, Universidad Nacional Autónoma de México, in 2008 reported the discovery of a new species la Bouvardia borhidiana found in the Sierra Madre delsud, Mexico.
In some states of Mexico the B. terniflora it is used as an antidote against the poison of vipers, scorpions, bees, ants and other insects as well as to combat cough, dysentery, stomach and head pain. In traditional medicine, the aqueous extract of its leaves is used in the treatment of diabetes.
