1. Orchid


There’s a wide variety of orchids, making it possible for you to choose the species that appeals to you. Generally, they have long, curving stems that are mostly covered with colorful flowers.

You may think orchids are difficult to grow, but there are care instructions that are straightforward enough for even beginners to follow. They’ll thrive in rooms with bright light, but make sure to avoid placing them in direct sunlight.

Perhaps the most tedious task involving orchid care is that you might need to repot it every two years. That’s if it stops blooming or if the roots have grown out of the original pot.

In order for your plant to last long, keep it in a warm and humid area. You can also look for soil and fertilizer that are specifically for orchids.

2. Ornamental Pepper Plant

Ornamental pepper plants are more commonly grown outdoors because they need the energy that direct sunlight provides. However, you can also grow them indoors in small containers. Do so, by placing them next to windows and giving them extra artificial light.

Ornamental pepper plants come in different colors such as red, orange, yellow, and purple; sometimes on the same plant! Theyhave different tastes depending on the type you grow too.

This plant can be used both for decoration and your dishes. Its leaves are toxic to humans and animals, though. So, make sure to remove the leaves first when you’re cooking with these peppers.

Its leaves are dark green with a long and narrow shape. If placed in the right environment, oleander plants can grow up to 12 feet tall.

However, it’s best not to grow this plant indoors if you have children or pets in your home. All of its parts are highly poisonous if ingested.

4. Orchid Cactus

The orchid cactus, or climbing cactus, is a succulent that comes in different shapes and sizes. They have long, flat stems and large, vibrant flowers.

You can place them in hanging baskets to showcase their trailing stems. When in bloom, the orchid cactus’ flowers are quite the eye-catcher.

Place them in rooms that have bright light in the morning and ample shade during midday. Because the orchid cactus’ natural habitat is found in forests and not deserts, it’ll require regular watering.

5. Ophiopogon


Ophiopogon, or mondo grass, is a type of ornamental grass native to China, Japan, and Korea. It’s evergreen and highly durable, which makes it a popular choice for decorating gardens and indoor ornamental containers.

It usually only grows less than five inches in height, so it doesn’t take up too much space. Keep ophiopogon plants in places with filtered sunlight for optimal growth.

This plant has long, thin leaves and in the summer, you may see some stalks of white or purple flowers. It’s a desirable addition to houses with a minimalist, modern, or East-Asian aesthetic.

6. Oscularia

Oscularia is a succulent with small, triangular, blue-green, or gray-green leaves. Native to South Africa, this plant is accustomed to growing on rocks and mountains.

Because it produces bright pink flowers, this plant is also called “Pink Ice Plant.” Oscularia plants grow best under plenty of sunlight for at least five to six hours a day.

Succulents can store a lot of water in their leaves, so keep oscularia plants in pots that have drainage holes to avoid waterlogging them. Only water them when the top three inches of soil is already dry.

Oxalis plants are simple to grow and they can last a long time. They’ll thrive in places where they can get around four hours of direct sunlight, then partial shade throughout the rest of the day.

8. Oplismenus


Oplismenus, also known as basket grass, is native to many countries and can be found on all continents except Antarctica. This plant’s stems can grow up to two feet long which makes it perfect for displaying in hanging baskets.

Its leaves are green with some white stripes. The plant grows quickly so you may want to trim it regularly to keep it bushy.

Oplismenus plants do well in bright, sunny rooms; away from direct sunlight. Aside from hanging baskets, you can also place them on top of a pedestal or tall table, letting the stems spill out over the container.
