Color Challenge-Flowers orchid.

The strange form of orchid flowers, sometimes very close to the pollinating insect, has always fascinated naturalists. The name orchids comes from the Latin orchis (testis) in reference to the two tubercles present at the base of certain terrestrial orchids. Aphrodisiac virtues have often been attributed to orchids. The names of "Sabot de Vénus", "Sabot de la Vierge", "Fleur du Paradis", and "Gilles de l'air" also recall the beliefs attached to them.
Already known to the Aztecs, vanilla is the only orchid grown as a spice. The orchidomania (heard the madness of orchids) reached its peak in the 19th century and continued into the 20th century. The plants were collected in the wild and sold at the price of gold. Today, orchids are widely grown. Numerous hybridizations have led to the creation of tens of thousands of varieties often better adapted than wild varieties to apartment cultivation.
The flower of the orchids is composed of 3 sepals and 3 petals. The central petal called labelle often has a particular shape.
We will only mention here some of the most common indoor orchids.
Species and varieties of orchids:
Orchids live in all environments and on all continents except the Arctic. The most beautiful ones often come from tropical regions. The 25,000 species described in the wild gave rise to tens of thousands of hybrids.
Their origin determines their precise temperature requirements, but all accept average temperatures of 15 to 25 ° C.
The Cattleya are native to Central and South America. Their flowers are spectacular, sophisticated and often fragrant. They are enjoyable at temperatures of 16 to 25 ° C and require a high humidity of the air.
The Cymbidiums are native to the Himalayas. They are part of the easiest orchid to grow and can even be grown outside in summer and in an off-frost room in winter. The new Cymbidium hybrids bloom throughout the year, not just in winter.
The Paphiopedilum (Venus Clogs) have a lip turned into a purse. Their flowers are spectacular. Their growth is often slow but flowering lasts several weeks.
Oncidiums like intermediate temperatures of 10 to 24 ° C. The flowers are often yellow, bronze or brown.
The Dendrobiums are native to Asia, Australia, New Zealand. The amateurs distinguish two types of Dendrobium according to the origin of the hybrids. Nobile Dendrobiums enjoy a cooler night temperature. Take them outside until the middle of autumn. Dendrobiums of the Phalaenopsis type are less demanding on the temperature differences for their floral induction. They will be grown all year round in apartments.
The Miltonia are native to the Andes. Their flowers remind one of their thoughts. They like temperatures neither too hot nor too cold (from 12 to 25 ° C). They bloom in early summer and autumn.
The Vandas are often of tropical origin (India Burma). They should be grown between 16 and 30 ° C. They are famous for their exceptional blue color.

-Indoor Orchid Care Tips:
Orchids need ample water but should be allowed to dry out some between waterings. One way to check for watering is by poking your finger about an inch into the growing media. If it’s dry, give it some water; otherwise, let it be. Indoor orchid plants also need adequate humidity, about fifty to seventy percent. There are various ways to increase the humidity in your home. Place a water-filled saucer or tray of pebbles beneath plants, mist plants daily, or use a humidifier. Fertilize orchids weekly or bi-weekly while they are producing new growth and decrease to monthly or bi-monthly intervals once they mature. Discontinue altogether once the plants go dormant. Additional orchid care tips include repotting, which is normally done every other year. If your orchids suddenly stop blooming but have suitable light, temperature, and humidity, then repotting may be necessary. Also keep an eye out for signs of pests or disease. Orchids are occasionally affected by mealybugs, scale, and aphids. These can usually be washed off or treated with insecticidal soap.
