  • It can thrive in almost any condition.
  • if you’re wanting beautiful blooms, keep it in a spot with bright, indirect light.
  • If kept in shade, Peace Lily will grow just fine but will rarely bloom.

Since they are a tropical plant, Peace Lily’s are sensitive to cold. Keep them away from any cold drafts and make sure to water frequently as they do prefer moist soil.

Caution: Peace Lily is a known toxin to cats and dogs if ingested.

3. Bamboo

Indoor bamboo plant varieties such as Lucky Bamboo or Bamboo Palm are known for their resiliency - and good feng shui!

Bamboo requires ample natural sunlight — but avoid direct light. One of the easiest indoor plants to care for, it only requires watering with room temperature filtered water whenever the soil appears dry.

Bamboo can be grown in either soil or water. If yours is in soil, ensure the pot has good drainage. Bamboo prefers moist soil but too much water can result in yellow and rotting shoots.

4. Zanzibar Gem

Zanzibar Gem

Also known as a Zeezee Plant, the Zanzibar Gem is one of the least-demanding indoor plants with great foliage payoff. The wide, waxy leaves and graceful long stems make Zanzibar’s a perfect desktop plant.

Because they’re a tropical perennial, they don’t like cold temperatures — so keep Zanzibar Gem indoors in bright to indirect sunlight away from drafty areas. These household plants are also drought-tolerant and can thrive under the hands of even the blackest of thumbs!

Zanzibar’s are resilient to pests and grow slowly so you don’t have to worry about pruning. However, once the plant does outgrow its pot it will require re-potting.

Caution: ZZ Plants are on the list of poisonous houseplants, with all parts of the plant being toxic to humans and pets if ingested.

5. Succulents


Cacti and succulents are a crowdpleaser when it comes to tough as nails, unkillable indoor plants! Extremely drought-tolerant and available in a variety of species, colours, and shapes, succulents will survive just about any condition thrown at them.

Here are some tips to keep in mind when buying succulents:

  • Because succulents store water in their leaves, they can go for long periods of time without having to be watered.
  • In a semi-shady spot, succulents will only require watering once every couple of months.
  • Some species may prefer bright, direct sunlight so in front of a window would be a good spot.
  • You will need to water succulents more frequently if they are in constant direct sunlight - but only when the soil is bone dry.

Succulents and cacti require a special potting mix that will control drainage, meaning once planted, they won’t require any type of upkeep.

6. Rubber Plant

Rubber plant

Just like its name, the Rubber Plant can be easily mistaken for a fake plant! Despite its rubbery texture, it makes a versatile statement plant for any room.

Rubber Plants are extremely sturdy and will grow only to the size of the pot that it is in. This makes them very easy to care for, especially when they only require sporadic watering and an odd pruning when branches become wayward.

Rubber Plants will grow wonderfully in a warm room out of direct sunlight. Near a window with sheer curtains will be perfect for this houseplant. If you notice the leaves beginning to droop, this is your signal to give it a good watering. You may also need to wipe leaves with a damp cloth if you notice dust on the plant - as this reduces its ability to photosynthesize.

7. Devils Ivy

Devils ivy

Also known as Pothos, the Devils Ivy plant is a fast-growing vine with waxy, heart-shaped leaves. This type of indoor plant does well in a hanging pot and can make an eye-catching feature in any room.

Devils Ivy is incredibly resilient and requires very little maintenance. In fact, you only need to water it whenever the soil is completely dried out. Although Devils Ivy can tolerate all light conditions including cold temperatures, it does prefer indirect light.

Since Ivy is a creeper, be mindful that leaves will require regular trimming to keep them from taking over. Cutting back from the stems will help manage the length of the vines.
