Coral vine

Scientific name: Antigonon leptopus
Family: Polygonaceae

Origin
Native to Mexico and possibly also parts of Central America.
Plant characters
It is a perennial climbing vine with stems often climbing up over vegetation.
Stem:
Antigonon leptopus is a fast-growing climbing vine that holds on via tendrils, and is able to reach 25 ft or more in length. 
Leaf:
It has cordate (heart-shaped), sometimes triangular leaves 2½ to 7½ cm long. 
Flowers:
The flowers are borne in panicles, clustered along the rachis.  Producing pink from spring to autumn
Roots:
it forms underground tubers and large rootstocks. 
Fruits:
The small brown fruit (i.e. achenes) are cone-shaped or three-angled (8-12 mm long and 4-7 mm wide) and shiny in appearance. These fruit usually remain hidden within the enlarged and persistent remains of the 'petals' (8-20 long and 4-15 mm wide), which turn dull pink and then eventually brown as they age.
Seeds:
It is a prolific seed producer. The seeds float on water. The fruit and seeds are eaten and spread by a wide range of animals such as pigs, racoons and birds. The tubers will resprout if the plant is cut back or damaged by frost.Tubers and root segments can also be spread by the movement of soil.

Varieties:
Antigonon leptopus - pink flower
Antigonon leptopus alba - white flower

Climatic requirements:
A. leptopus prefers to grow in areas with warm temperatures and high precipitation at low elevation (i.e., from sea level to about 1000 meters. 
It tolerates drought well by shedding leaves and re-growing strongly after rains. 
Foliage dies back at temperatures just below freezing and the roots die if the soil freezes.
Soil:
A. leptopus has the ability to grow in almost any soil type including coral-derived soils, sandy soils, seasonally waterlogged soils, and alkaline limestone soils.

Propagation:
Propagated through seeds, tubers and suckers.
Uses:
Ornamental:
A. leptopus is used as potted plant.
A. leptopus is commonly planted as an ornamental in gardens and yards and as a “fence cover plant” in warm climates in tropical and subtropical regions. 
Human food and beverage:
It is also used as a nectar source for honey production.
Antigonon leptopus was prepared for consumption by the aboriginal inhabitants of Baja California in a way somewhat reminiscent of preparing popcorn. 
Medicinal:
A. leptopus is also used in traditional medicine in the West Indies and Central America. For example, tea prepared from the leaves, aerial parts, and flowers of A. leptopus is used as a remedy for colds, throat constriction, and pain relief in Jamaica, St. Lucia, Mexico, and Trinidad-Tobago.

Environmental impact:
Antigonon leptopus is regarded as an environmental weed in many parts of the world. 
A. leptopus is an aggressive invasive vine with the potential to collapse native plant communities by displacing native species, changing community structures and altering ecological functions. This fast-growing vine forms dense colonies that engulf native vegetation, climbing high into forest canopies and shading-out herbs, shrubs, and trees in the understory of native forests. Consequently, in just one or two growing seasons, this species can completely out-compete native vegetation communities.

Pomegranate flower

Scientific name: Punica granatum 
Family: Lythraceae

The name pomegranate derives from medieval Latin pōmum "apple" and grānātum "seeded". 
Pomegranate is one of the commercially important fruit crops of India. It is native to Iran.

🌲Plant Characters:
A shrub or small tree growing 5 to 10 m high, the pomegranate has multiple spiny branches and is extremely long-lived, with some specimens in France surviving for 200 years.
🍀Leaves:
Leaves are opposite or subopposite, glossy, narrow oblong, entire, 3–7 cm long and 2 cm broad. 
🌹Flowers:
The flowers are bright red and 3 cm in diameter, with three to seven petals.
Some fruitless varieties are grown for the flowers alone.
🍊Fruits:
They are Red-purple in color
The pomegranate fruit husk has two parts: 1. An outer, hard Pericarp
2. An inner, spongy mesocarp  which comprises the fruit inner wall where seeds attach. Membranes of the mesocarp are organized as nonsymmetrical chambers that contain seeds inside sarcotestas, which are embedded without attachment to the mesocarp. 
In mature fruits, the juice obtained by compressing the seeds yields a sour flavor due to low pH 4.4 and high contents of polyphenols, which may cause a red indelible stain on fabrics. Primarily, the pigmentation of pomegranate juice results from the presence of anthocyanins and ellagitannins.
🥜Seeds:
Number of seeds in a pomegranate can vary from 200 to about 1,400.

📌Land preparation:
Land is prepared by ploughing, harrowing, leveling and removing weeds.

📌Planting Material:
Pomegranate is propagated vegetatively by cuttings, air layering or gootee.

Planting season
Air layering is usually done during the rainy season and also in November-December. 

🌴Planting:
Planting is usually done in spring (February-March) and July-August in sub-tropical and tropical regions respectively.

📌Spacing:
5m x 5m
Closer spacing increases disease and pest incidence.
📌Pit size:
Pits of 60 X 60 X 60 cm. size are dug

The pits are filled with top soil mixed with 20 kg. farmyard manure and 1 kg. super phosphate.

Cuttings/air layers are then planted and staked. Irrigation is provided immediately after planting.

📌Fertilizer recommendation:
The recommended fertilizer dose is 600-700 g. N, 200-250 g. P2O5 and 200-250 g. K2O /tree/year.

🌦️Irrigation:
Regular irrigation till the monsoon sets in. Weekly irrigation in summers and that during winters at fortnightly intervals is recommended. The check basin system of irrigation is usually followed.

✂️Training:
Plants are trained on a single stem or in multi-stem system. 

✂️Pruning:
Pruning is not much required except for removal of ground suckers , water shoots, cross branches , dead and diseased twigs and also to give shape to the tree. A little thinning and pruning of old spurs is done to encourage growth of new ones.
🐞Insect Pests:
Insect pests mostly observed are fruit borer, mealy bugs, aphids, white fly and fruit sucking moths. Spraying with dimethoate , deltamethrin or malathion etc. depending upon the type of pest infestation has been found to be effective in most cases.

🍂 Diseases:
 The main diseases reported are leaf spot and fruit rot. Application of Mancozeb (2g./l.) during rainy season in case of the former and application of Kavach (2g./l) and Carbendazim/Thiophanate methyl/Baycor/Benomyl (1g./l.) during September/October in case of the latter has been found to be effective in most cases.

🍁Disorders:
Fruit cracking is a serious physiological disorder observed in young fruits is due to boron deficiency and that in fully grown fruits is mainly due to moisture imbalances. Tolerant varieties viz. Bedana Bose and Khog may be cultivated and in other cases spraying with calcium hydroxide soon after fruit set has been found to be beneficial.

🏺Medicinal Properties:
📌Pomegranate is a potent antioxidant. 
📌This is rich in flavonoids, anthocyanins, punicic acid, ellagitannins, alkaloids, fructose, sucrose, glucose, simple organic acids, and other components and has antiatherogenic, antihypertensive, and anti-inflammatory properties.

Stinking Passion Flower

Scientific name: Passiflora foetida 
Family: Passifloraceae

It is a species of passion flower out of 550 species of Passiflora that is native to the southwestern United States (southern Texas and Arizona), Mexico, the Caribbean, Central America, Africa ,and much of South America. 
🌲Plant characters
🌿It is a creeping vine like other members of the genus, and yields an edible fruit. 
🌿The specific epithet, foetida, means "stinking" in  Latin and refers to the strong aroma emitted by damaged foliage. 
🌿The stems are thin, wiry and woody, covered with sticky yellow hairs.
🌿The leaves are three- to five-lobed and viscid-hairy. 
🌿They give off an unpleasant odour when crushed. 
🌸The flowers are white to pale cream coloured, about 5-6 cm diameter. 
🍈The fruit is globose, 2-3 cm diameter, yellowish-orange to red when ripe, and has numerous black seeds embedded in the pulp; the fruit are eaten and the seeds dispersed by birds. 

🌦️Climatic requirements:
Plants require a temperature not lower than around 16°c when they are flowering in order to ensure fruit set.

Soil:
Requires a humus-rich, moist but well-drained soil and a position in dappled shade. 
Prefers a circumneutral soil, disliking very acid or very alkaline conditions. 
Passiflora species tend to flower and fruit more freely when grown in soils of only moderate fertility. 
plant can flower and produce fruit all year round. 

♀️Propagation
📌Seed
Best sown as soon as it is ripe along with the pulp which will help break down the seed coat and speed up germination. Stored seed should be soaked for 24 hours in warm water and germination time can be reduced if the seed is then mixed with the juice of a fresh passion fruit (of any species) Even so, it can take 12 months for stored seed to germinate. Place the seed tray in a shady position, maintaining a temperature around19 - 24oC.
📌Cuttings:
Cuttings of young shoots, taken at the nodes. The cuttings root best in a neutral to slightly acid compost, but 100% sharp sand also produces good results.
Cuttings of fully mature wood taken at a node. They can take 3 months, but there is usually a high percentage
📌Air layering can be done easily.

✂️Pruning
Plants are very tolerant of pruning and can be cut back to ground level if required to rejuvenate the plant

🛠️Uses:

🍀Medicinal uses:  This  species can be helpful in treating digestive problems, including dyspepsia and diarrhea; or used as an astringent and expectorant for nervous conditions and spasms.

🍀Edible Uses
Fully ripe fruit - raw. Sweet and juicy
🚫Do not eat the under-ripe fruit since it can be toxic.
🌱Leaves - cooked. Used as an ingredient in soups
🌳Agroforestry Uses:
The plant is used as a ground cover and as a hedge

🐞Other Uses:
Substances in the leaves deter feeding insects

😮An interesting fact about plant:
The bracts of this plant serve as insect traps, but it is as yet unknown whether the plant digests and gains nourishment from the trapped insects or if it merely uses the bracts as a defensive mechanism to protect its flowers and fruit. This is still an issue of debate and research among carnivorous plant enthusiasts.

🔻Warning
The unripe fruits contain cyanide and are poisonous.

     Spider plant due to its fast and dense growth the spider plant has become one of the most popular room and office plants worldwide. Plant is a native of South Africa.

Plant Characters:
🍀 Chlorophytum comosum grows to about 60 centimetres (24 in) high. 
🍀 It has fleshy, tuberous roots, about 5–10 cm long. 
☘️ The long narrow leaves reach a length of 20–45 cm and are around 6–25 millimetres wide.
Flowers:
🌸Flowers are produced in a long branched inflorescence, which can reach a length of up to 75 cm and eventually bends downwards. 
🌸Flowers initially occur in clusters of 1–6 at intervals along the stem of the inflorescence. Each cluster is at the base of a bract,  which ranges from 2–8 cm in length, becoming smaller towards the end of the inflorescence. 
🌸Most of the flowers which are produced initially die off, so that the inflorescences are relatively sparsely flowered.
🌸The inflorescences carry plantlets at the tips of their branches, which eventually droop and touch the soil, developing adventitious roots. 

🌾Cultivation:
🌦️Climate and Soil:
🌞Sunlight:
☀️A half-shaded area would be preferable.
☀️Do not expose the plant directly to mid day sun especially in summer.

🤙Chlorophytum comosum
This is the wild form of chlorophytum comosum is characterized by pure green leaves without any markings.

🌳Planting:
🚩The dense and rapidly growing root ball of the chlorophytum comosum requires much space, so this green plant should be placed in a pot with sufficient space. 
🚩There should be a 2 to 3 cm area filled with soil between the roots of the plant and the end of the pot. 
🚩As soon as the roots can be seen, because they displace the substrate on the surface or even damage the pot, the spider plant should be transplanted as quickly as possible into a larger pot independent of the season.

💧Irrigation:
Spider plant should be irrigated regularly.
Waterlogging should be avoided.

🌱Propagation:
1.Sprouts: small daughter plants emerge from the hermetic blossoms after they have faded.
2. Seeds:The wild form as well as a few cultivated varieties of the spider plant form small capsule fruits and in each of them three seeds will approach. If the capsule is opened, the black seeds will fall to the ground.

🍂Pests and diseases
🐞Pests:
Aphids, Mealy bugs, Whiteflies, Spidermites
🍃Diseases:
Bacterial wet rot: Waterlogging causes bacterial wet rot. So avoid waterlogging.

🔧Uses
Used as indoor plant
Used in hanging pots
🔺The NASA Clean Air Study determined that this plant was effective at removing common household air toxins formaldehyde and xylene and reduce indoor air pollution.
🔻Approximately 70 Spider plants would neutralize the formaldehyde released by materials in a representative (ca. 160 m2 [1,700 sq ft]) energy-efficient house, assuming each plant occupies a 3.8 L pot.
