Petunia:
Petunia is genus of 35 species of flowering plants of South American origin, closely related to tobacco, cape gooseberries, tomatoes, deadly nightshades, potatoes together with chili peppers; inwards the trace solid unit of measurement Solanaceae. The pop bloom of the same cite derived its epithet from the French, which took the give-and-take petun, pregnant "tobacco," from a Tupi–Guarani language. An annual, most of the varieties seen inwards gardens are hybrids.
The rootage of Petunia × hybrida is persuasion to hold out yesteryear hybridisation betwixt P. axillaris (the large white or night-scented petunia) together with P. integrifolia (the violet-flowered petunia). P. axillaris bears night-fragrant, buff-white blossoms alongside long, sparse tubes together with somewhat flattened openings. The species was outset sent from South America to Paris inwards 1823. P. integrifolia has a somewhat weedy habit, spreading stems alongside upright tips, together with pocket-sized lavander to majestic flowers. It was discovered inwards South America yesteryear the explorer James Tweedie, later on whom the genus Tweedia is named, who sent specimens to the Glasgow Botanical Garden inwards 1831. Many open-pollinated species are also gaining popularity inwards the abode garden.A broad arrive at of bloom colours, sizes, together with found architectures are available inwards both the hybrid together with open-pollinated species.
Some botanists house the plants of the genus Calibrachoa inwards the genus Petunia.Petchoa is a hybrid genus derived from crossing the genetically similar Calibrachoa together with Petunia.
In botanical classification, tobacco, tomato, potato, together with petunia are all inwards the trace solid unit of measurement Solanaceae.
Petunias are to a greater extent than frequently than non insect pollinated, alongside the exception of P. exserta, which is a rare, red-flowered, hummingbird-pollinated species. Most petunias are diploid alongside fourteen chromosomes together with are interfertile alongside other petunia species.
The tubular flowers are favoured yesteryear some Lepidoptera species, including the Hummingbird hawk moth.The flowers are eaten yesteryear the larvae of the corn earworm, Helicoverpa zea together with the cabbage looper, Trichoplusia ni.
Petunia seeds germinate inwards 5 to xv days. Petunias tin tolerate relatively harsh conditions together with hot climates. They demand at to the lowest degree v hours of sunlight every day. They grow good inwards depression humidity, moist soil. Young plants tin hold out grown from seeds. Petunias should hold out watered ane time every ii to v days. In drier regions, the plants should hold out watered daily. Dead petals should hold out pruned together with thus that the younger branches tin flourish. Maximum increment occurs inwards piece of cake spring. Applying fertilizers ane time a calendar month volition aid the found grow quickly. Petunias tin hold out cultivated inwards hanging baskets.
This type of petunia has the largest flowers, upward to 4 inches (100 mm) inwards diameter. Of all the petunias these bring the widest multifariousness of forms together with colours but are the most probable to hold out damaged yesteryear heavy rain. There are 4 types of grandiflora together with they are classified yesteryear their colours: ‘Daddy Series’ (shades of pinkish together with purple), ‘Merlin Blue Morn’ (blue together with white), ‘Supercascade Series’ (many colours) together with ‘Ultra Series’ (many colours, including bi-colour).
Hedgifloras or spreading petunias (sometimes called ground-cover) are characterised yesteryear their depression pinnacle (usually well-nigh vi inches), but they bring a large spread (about iii to 4 feet). They volition encompass a large area, provided they bring adequate H2O together with fertilization. ‘Purple Wave’ was the outset introduced cultivar of spreading petunia together with grows to a pinnacle of 4 inches (100 mm). ‘Tidal Wave’ is some other spreading type of petunia, but is much taller (between xvi together with twenty-two inches). 'Surfinia' petunias are some other type of spreading petunia propagated yesteryear cuttings. ‘Opera Supreme’ is a cultivar alongside large flowers.
Multifloras are one-half the size of grandifloras, beingness 2 inches (51 mm) inwards diameter. They are non easily damaged inwards heavy pelting together with are to a greater extent than sun-tolerant. Multiflora petunia cultivars include: 'Carpet Series "(many colours) together with 'Madness Series' (many colours). They spread chop-chop together with are ideal for baskets. Millifloras are the smallest of the petunias, beingness well-nigh 1-inch (25 mm) across. These are commonly mixed alongside other plants inwards containers, along garden beds together with edges.
Millifloras are available inwards 'Fantasy Series' (red, purple, pink) together with are the easiest to find. 'Supertunia Mini Series' (blue, pink, lilac, majestic together with white) are also available inwards the milliflora category. They tolerate harsh conditions ameliorate when compared alongside grandifloras together with multifloras.
