Elegant and attractive, the exotic orchid is one of the most popular houseplants. To the uninitiated, caring for one of these attractive flowers can seem a daunting proposition. But it really isn’t. Requiring just a little care and patience, the orchid is one of the most visually rewarding plants around.
This guide to the different types of orchids will not only seek to explain what an orchid is, we will also highlight some of the most interesting types. The suggestions below range from high maintenance specimens to easy to care for plants that are ideal for the home or garden.
The exotic orchid is an increasingly popular houseplant.
What is an Orchid?
Members of the orchidaceae family, there are currently over 800 genera and 25,000 recorded orchid species. This is before you also take into account the 100,000 cultivars and hybrids also available.
Many people think that the exotic looking orchid is a high maintenance plant that requires very strict growing conditions in order to flourish. However, this is not true. The orchid is actually a very versatile plant. They can be found growing in most regions of the world.
This geographical spread means that the different types of orchids can vary in size, weight, color and growing preferences. Many of these differences are related to the specific varieties’ natural habitat and are vital for the plants continued health and success. Despite these discrepancies, most orchid plants are easily identifiable.
A perennial plant, the orchid flower typically displays bilateral symmetry. Depending on the exact type the plant has set growing habits. All the different types of orchids can be classified as either Monopodial and Sympodial:
- Monopodial plants are those that produce a stem from a single, central bud. New leaves emerge from the apex every year. The stem of the plant grows vertically.
- Sympodial plants grow to a certain length before setting flowers. After the flowers fade, the stem dies back to be replaced by a new one. The stems of sympodial plants tend to grow laterally but can be trained.
Orchid plants can also be grouped by the environment in which they grow. Here, the two groups are termed Terrestrial and Epiphytic:
- Terrestrial plants are rhizomatous plants, growing from underground tubers or corms. These store the necessary nutrients for the plant to grow and flower.
- Epiphytic plants, also called the aerial orchid, grow aerial roots. This enables the plants to anchor themselves to trees, shrubs and other nearby structures. They are commonly found growing wild in subtropical regions. Sometimes called air plants, Epiphytic plants cannot photosynthesize. Instead they obtain their nutrients by forming a symbiotic relationship with fungal species, entwining their root systems in exchange for nutrients.
The Ideal Orchid Growing Conditions
An increasingly popular houseplant, different types of orchids require different growing conditions. Some like full shade positions whilst others prefer to bask in lots of sunlight. While some types like wet or even waterlogged soil others prefer arid conditions. Potted types often thrive in orchid mixes, such as Better-Gro Phalanopsis Mix or sand. Take the time to research your chosen variety before purchase.
Different orchid varieties and cultivars have different needs and growth preferences.
While getting the growing position right can be difficult, the floral attraction and interest these plants provide makes it well worth the effort.
If you are cultivating an orchid in a pot, it is worth investing in an Orchid Pot. These are designed to maximize drainage whilst also encouraging air flow around the roots. Not the most aesthetically pleasing container, once planted up the orchid pot can be placed inside a more attractive container if you wish. This guide to choosing the right pot for your orchid will help you to find the ideal container.
Specimens growing in pots require regular repotting. Our guide to repotting orchid plants takes you through everything that you need to know.
Perennial plants, once established and if correctly cared for, all orchid plants flower year after year until they die. To encourage plants growing undercover to rebloom, place them in an indirect light position and allow them to experience cooler air during the night time.
Potted plants also benefit from a weekly dose of fertilizer and growing in appropriate material. Aerial rooted types of orchids also grow in water.
While a general purpose houseplant feed can be applied, it is far better to give your houseplant a specific orchid fertilizer. Miracle-Gro Orchid Plant Food contains all the nutrients that your growing plants require.
Hybrid orchid varieties are increasingly popular. A low maintenance option, hybrids are pleasingly easy to care for and are often devoid of the more difficult care aspects that accompany pure orchid varieties.
