Such exotic flowering plants as orchids have been increasingly decorating apartment windows.
At the same time, some types of these flowers are unpretentious and are great for novice florists, for example, the Philadelphia orchid.
All information about this plant: the history of origin, distinctive features, as well as the rules for the care, reproduction and cultivation of a purple-pink beauty can be found in our article.
History of origin
Philadelphia Orchid attracts flower growers not only with exquisite flowers, but also with its unpretentious care... This species is a hybrid, which has collected all the best from its "parents" - Phalaenopsis Schiller and Stewart.
The Philippines is considered the birthplace of Philadelphia, and in natural nature this species can be found not only on the crowns of trees in tropical forests, but also on coastal snags and near the volcanoes of Southeast Asia and Australia.
Appearance and photos
The Philadelphia orchid is botanically little different from other phalaenopsis. The root system of this species is quite developed. Also, aerial roots grow from the leaf sinuses, which, due to the presence of chlorophyll in them, have a greenish-silver color and saturate the plant with water and nutrients directly from the air.
Important! Philadelphia does not have pseudobulbs, since it is an epiphyte, i.e. does not parasitize on other plants, but uses them only as a support.
The vertical stem of this hybrid is very short. and it is practically invisible due to 3-6 fleshy leaves. Their size is also small: the length reaches 20 cm, and the width is 10 cm, while they have an unusual color - the main color is silvery-green and additionally there is a marble-like camouflage pattern.
Philadelphia has several peduncles reaching 60-70 cm in height. Each peduncle can have up to 20 flowers, the diameter of which is usually about 8 cm.The flowers are predominantly purple-pink, but can also be supplemented with purple veins, brown blotches in the center, and the lateral sepals are specks of different shades of red. The central petal (lip) is bifurcated and outwardly it resembles "horns".
Phalaenopsis Philadelphia prefers to grow at an altitude of 400 m above sea level, and the higher it grows, the brighter and more saturated color the flowers have.
Flowering can last for several months, due to the fact that the buds open gradually and stay open for a long time. This type of phalaenopsis can only be pollinated with the help of insects.since pollen cannot travel through the air due to accrete stamens.

What is the difference from other varieties?
Despite similarities with other types of orchids, Philadelphia has some distinctive features:
- it can be found only in the tropical lowland and mountain forests of Southeast Asia and Australia (in the northeastern part), and orchids are widespread everywhere (with the exception of Antarctica);
- it belongs to epiphytes and does not have pseudobulbs, unlike other types of orchids, which are terrestrial plants;
- its flowers are all approximately the same large size, while in other species on one peduncle there may be flowers of different sizes;
- her flowering is longer and can occur repeatedly throughout the year;
- it is less demanding on growing conditions at home, unlike others.
The flowering period of Philadelphia is the most enjoyable for growers.
When and how?
At home, with the necessary care, this type of phalaenopsis usually begins to bloom from February to May.
Attention! Each plant, even of one species, is individual, so the flowering periods may differ: one flower can bloom in February, and the other in August, and this is considered the norm.
This orchid has large flowers and bloom almost simultaneously, while as soon as some buds begin to wither, others begin to open, which ensures long-term flowering.
To ensure that Philadelphia does not stop annually pleasing with its flowering, it needs to be provided with proper care. Before flowering, this type of orchid does not require special care., it is enough to follow the basic recommendations for care.
But after the last flower falls, the phalaenopsis needs to be given a little rest and gain strength. To do this, you should:
- reduce watering to 1 time in 7-10 days;
- you can refuse feeding (allowed once a month);
- only after the peduncle is completely dry it should be cut off.
If new buds have already begun to form on the peduncle, then you can cut it off, leaving at least 1 cm from the bud.
What if it doesn't bloom?
Main the reason Philadelphia does not want to bloom is due to improper care behind the plant. Pay attention to the following:
- The flower needs a large amount of not direct, but diffused sunlight.
- For Philadelphia to release its buds, it needs a shake-up, which consists of a short (up to 2 weeks) period of drought. Also, the pot should have a drainage layer that will prevent water from stagnating.
- An orchid needs a daily temperature drop of 2-6 degrees, i.e. during the day, the ideal temperature is 18-22 degrees, and at night - 16-20 degrees.
- Fertilizers should be balanced - mainly potassium-phosphorus-nitrogen fertilizers.
- Also, as a shake, the plant can be removed for a couple of days in a dark and cool place, which will wake him up from sleep.
How to take care at home?
Timely and long-term flowering of Philadelphia at home is ensured only by proper care of the plant.
This type of phalaenopsis should be located in a bright place, but not under direct sun, since the sun's rays will quickly burn the leaves. If necessary, shade the window with newspaper or plain paper..
Preparing the soil and pot
Special soil for orchids can be purchased either in the store or prepared on your own, since a universal soil for such a plant will not work. For self-preparation of the soil in equal parts you will need:
- dry coniferous bark;
- coarse sand;
- moss for the top layer.
Be sure to lay a drainage layer on the bottom.
The pot is also very important for the health of the flower - it should be predominantly transparent to allow photosynthesis in the roots, and with a smooth inner surface to prevent roots from growing into it.
Temperature range for Philadelphia is as follows:
- daytime temperature is about 18-22 degrees;
- night - within 16-20 degrees;
- a daily temperature difference of 4-6 degrees is required, which contributes to the growth and development of the plant.
Important! Prolonged low temperatures negatively affect the flower - it stops growing and developing.
In a natural environment, the air is quite humid (about 80%), therefore at home, you should provide such a high humidity: Spray the flower once every 2 days, wipe the leaves once a week and create a natural moisturizer - a container with water.
This hybrid does not tolerate either drafts or stuffiness in the room.
For Philadelphia, a significant amount of diffused daylight should be provided - at least 10 hours. Therefore, in winter, you will need to use additional artificial lighting.
Watering this type of phalaenopsis should be treated with special care.:
- Water once every 2-3 days, moistening the soil on top or placing the flower under the shower.
- Do not use the immersion method.
- During flowering, watering is carried out once a week, and after that it can be even less often.
- The water should be warm and better than rainwater.
Fertilizers for phalaenopsis need to buy specialbecause their composition is balanced. It is recommended to introduce them with every third watering, but with active growth, you can increase the frequency, but during the rest period, on the contrary, reduce it.
reference... It is better not to buy micronutrients separately, so as not to overdo or under-supply some substance.
A plant newly purchased from a store should be immediately transplanted into prepared soil and a pot and removed for 2 weeks to adapt to a dark place and not water. Then replanting the orchid is enough once every 2 years in order to renew the soil, but only after the end of flowering.
How to propagate?
Florists distinguish several methods of reproduction in Philadelphia:
- shedding children;
- division of the root system;
- or cuttings.
- When a baby is born near the root and gives 3-4 roots about 5 cm long, then you can plant it in a separate pot. Expect the first flowering in six months.
- You can propagate Philadelphia by splitting the root system at any time. You should carefully separate the roots and plant the separated part in a new pot.
- After the orchid has faded, a stalk can be formed from a drying peduncle - the length should be 4-10 cm.It should be placed in a container with fine bark and moss and placed in greenhouse conditions - a temperature of about 25 degrees, diffused light, regular ventilation and timely watering using a spray bottle. After a couple of weeks, buds can form on the cuttings and after that they can be transplanted into separate pots.
Important! With any method of reproduction, the places of cuts and divisions should be treated with activated or charcoal.
Diseases and pests
Main the cause of the onset of the disease in Philadelphia is non-compliance with the rules of care:
- the temperature regime is violated;
- improper lighting and humidity;
- wrong regime or method of watering and feeding;
- unsuitable container and soil.
The most dangerous and common pests on this hybrid are:
- various ticks;
- mealy worm;
To fight, it is allowed to use folk remedies in the early stages. (soap solution or decoction of nettle / chamomile / dandelion), and in difficult situations, resort to chemicals - insecticides, fungicides, ascaricides.
It is necessary to carry out processing in several approaches in order to destroy all the larvae and eggs, while it is imperative to take a break between approaches.
Experienced florists recommend prophylaxis immediately after buying a plant.
- To identify pests, you should completely submerge the hybrid with its roots in water for 2 hours.
- They also detect the presence of rot and other diseases on the roots. Damaged roots must be cut off, and the cut sites must be treated with chopped charcoal or activated carbon.
- You can treat the entire flower with a fungicide.
- Before planting, it is recommended to neutralize the soil by heating it in a microwave oven or freezing it in a freezer.
A novice florist who wants to start growing orchids can safely choose Philadelphia. Bright and large purple-pink flowers will delight the owner for a long time... The main thing is to provide proper care:
- tropical temperature with a mandatory daily difference;
- high humidity without drafts;
- diffused light;
- transparent pot with special soil and drainage.
