It's a great choice for a room that faces north, since it can help keep the air cooling system cool or warm and reduce humidity.It is an easy to grow plant that can tolerate drought conditions. It thrives in indirect bright light and a warm, average temperature is the ideal. However, it is sensitive to cold winds and must be protected. Make sure to water regularly with warm chlorinated water, and avoid over-watering since this could cause root rot. Reduce the frequency of watering during winter.The African Fig Tree can be fertilized every two weeks throughout the growing season with an all-purpose, balanced liquid houseplant feed. Repotted at the beginning of the growing season or when it becomes pot bound. Avoid repotted plants during cold months as this can stress the plant and lead to leaf drop. In contrast to other houseplants, the fig isn't susceptible to disease and pests. However, it can be susceptible to mealy bugs.Yukka PlantYucca plants grow in arid areas, such as the southwest United States and northern Mexico. They are an evergreen plant that can live for hundreds of years, and can be found in a wide variety of shapes, forms and colors. The two most popular varieties of yucca used as large house plants are the Adam's Needle (Y. filamentosa) and the Spanish Bayonet (Y. aloifolia). Both have thin trunks that reach up to 15 feet in height and stiff leaves that have sharp points which can cut the skin. Yuccas grow slowly and could remain as tiny shrubs for several years prior to they outgrow their containers.Cast Iron PlantCast iron plant (Aspidistraelatior) can be found in shade or in dimly lit areas indoors. It has long leaves and a rhizome underground that produces new growth. It can grow to three feet tall and wide outdoors, but it stays smaller indoors. The leaves can range from blueish to green with spots or stripes, and may show variations. The plants look a bit similar to asparagus and belong to the same family (Asparagaceae).Cast Iron Plants are tolerant of low light levels, and one of the few plants which can survive without water for days. It cleans indoor air because it absorbs harmful chemicals like Formaldehyde.It is a sturdy houseplant, but it is not an extremely fast grower. It is recommended to repotte it every three to five to years. Repot in the spring using pot soil. Make sure to use a bigger container when you plant it. It is tolerant of drought, but prefers moderate moisture. Overwatering causes root rot. A good rule of thumb is to water only when you can stick your finger in the soil and not feel any dampness.Swiss Cheese PlantThe Swiss Cheese Plant, also known as Monstera Deliciciosa, is one of the most well-known large house plants because of its striking leaf fenestrated. It is particularly popular with the boho-inspired design movement and looks good in the majority of styles of decorating. It is a tropical tree that thrives in warm temperatures and bright indirect light.Watering is simple. You only need to water your plants when the top inch or more of soil is dry. Overwatering can lead to root rot. In common houseplant , decrease the frequency of watering with your finger or a moisture gauge to measure the soil's moisture levels. Only water when it is necessary. It's also a good idea to keep the plant away from air vents and windows in the winter months to help keep it warm.Feed your plant every week with a liquid plant feed that has a ratio of 5-3-3. It is a good idea to wait a month following the repotting process before fertilizing. This is because roots are more sensitive after the repotting.Bird's Nest FernThe Bird's Nest Fern is one of the most tropical-looking house plants. It is also known as the hanging fern because of its long, curled leaves that resemble wings of birds. Like other ferns it is epiphytic or lithophytic (grows on wood or rocks) by nature, however it can thrive in normal soil blends that are uniformly moist.They are easy to grow, but watch out for bacterial disease. It appears like leaf rot and can be a serious problem if plants are in contact with soil. The symptoms start with small, water-soaked translucent spots that grow in size and then turn reddish-purple as they deteriorate.To avoid this, put ferns in bright indirect light and shade them whenever possible with sheer curtains. Ferns are an excellent option to add a bit of tropical glam to shady rooms in your home such as dormitories and basements. If the fronds begin turn yellow, it's probably the result of too much heat or exposure to draughts. A humidifier and misting are two great ways to combat this.Rubber PlantRubber Plants (Peperomia Obtusifolia) are easy-care plants that thrive in a broad range of temperatures. They are most often used as a houseplant, but can also be planted in the garden. This plant can tolerate light shade, but prefers a spot that is well-lit in the house that receives indirect sunlight.The frequency of watering is dependent on the time of year. In summer, the soil may dry out very quickly due to intense sunlight. In winter, the plant will need less water.The sap of this plant contains caoutchouc, which gives rubber its elasticity. This compound may cause irritation to mucous and skin tissues, and is poisonous when consumed.

Pack the wound with a little damp moss, then wrap it in plastic.Heartleaf PhilodendronThe Heartleaf Philodendron can be grown in a wide range of conditions. Its green trailing vines make a great addition to any room and also help clean the air.

Simply cut common houseplant to a node, and place it into water or a moist soil. After a month or so the plant will begin to develop roots. If this happens, the philodendron plant can be relocated to an everlasting container.DieffenbachiaDieffenbachia is a classic and we love it due to its lush foliage, low maintenance needs and easy care. Native to the tropics, it adapts well to warm indoor temperatures and thrives in indirect light.Dieffenbachia plants can root in water or soil but we prefer to grow them in an airy and light-growing medium like perlite (chunky, spongy rocks). A mixture of peat and loam is ideal, or a 1:1 mixture of perlite and soil.The gills of water roots enable them to extract oxygen from the water, in contrast to soil roots, which are unable to breathe underwater and are susceptible to root rot. This could have evolved as a way to survive in their tropical surroundings. Dieffenbachia sap, roots and leaves are poisonous to humans and pets when eaten. Use gloves when handling this plant and be cautious around children. The sap contains toxins that can irritate the tongue and throat and cause irritation to the eyes and trigger skin reactions. If you have to contact the plant, you should use a mild soap and avoid touching the sap.
