Sharing is caring!

Whether you’re already a pro gardener or just starting to appreciate plants, one type of plant that you should probably consider is a cactus. Thanks to their striking appearance, unique forms, and easy-to-care nature, cactus plants quickly make an excellent and decorative way to boost up any dull space in your house or garden. 

Most cactus plants or cacti are native to the Americas and are drought-tolerant. They are slow-growing and relatively self-sustaining, which makes them suitable as houseplants even for someone lacking a green thumb.

cactus plants

Cacti, which belong in the botanical family Cactaceae, have areoles. These are small bumps along the stems in which the spines grow from.

Areoles are parts of cactus plants that distinguish them from other succulents. For that reason, all types of cactus can be classified as succulents, but not all succulents can be considered as cactus.

Not only do they add charm in any living space, but they are also easy to grow and maintain. If you want to learn more about different cactus plants, we’ve summarized below the most popular cactuses.

Moon Cactus (Gymnocalycium mihanovichii)

Other common names: Hibotan cactus, chin cactus

Moon cactus plants, known scientifically as Gymnocalycium mihanovichii, are one of the most popular types of cacti for home gardens.

Interestingly, these cacti cannot produce chlorophyll. They need a stock cactus that produces such pigment in which they can be grafted onto for them to thrive well. For that reason, the term “mutant cactus” is a standard reference for these plants.

You’ll quickly recognize them for their vivid neon orange, yellow, purple, red, or pink lollipop-like shapes that sit atop a rootstock cactus, like Hylocereus undatus (1). This type of cactus is native to South America, particularly to desert habitats in the region.

Moon cactus plants can be grown indoors if provided with sufficient light. Classified as small cactus plants, each of these cacti grows only up to 0.5 inches in width. However, some cultivars can grow up to 8 inches in diameter.

Popular cultivars of moon cactus plants:

  • Gymnocalycium mihanovichii var. friedrichii ‘Hibotan’
  • Gymnocalycium mihanovichii’ Hibotan Nishiki’
  • Gymnocalycium mihanovichii var. friedrichii ‘Pink-Kuro’
  • Gymnocalycium mihanovichii var. friedrichii ‘Akagurohibotan-Nishiki’

Bunny Ear Cactus (Opuntia microdasys)

Other common names: polka dot cactus, angel’s wings cactus, neon cactus, golden bristle cactus, bunny cactus

Bunny ear cactus plants wouldn’t be named as such if not for their pairs of pad-like stems that resemble a bunny’s ears. Surely, the interesting appearance of this plant quickly catches a cactus aficionado’s attention, but what makes this desert plant even more appealing is that it requires little to no maintenance.

Known scientifically as Opuntia microdasys, bunny ear cactus plants grow up to 40 to 60 m in height. If planted outdoors, they can grow up to 90 cm (3 ft) tall and 1.8 m (6 ft) wide.

They are clump-forming cacti that do not develop spines. Instead, they feature clusters of white or yellow glochids, with each glochid measuring about 2 to 3 mm long. The yellow flowers are globular and reach up to 3 cm in width (2). 

Bunny ear cactus plants are native to central and northern Mexico (2). This type of cactus plant requires a well-drained container, whether planted indoors, but it can also be grown outdoors. Occasional pests include scale insects and mealybugs, which can easily be treated with alcohol-soaked cotton balls.

The genus name Opuntia originated from the Greek word Opus, a place in Greece where cactus-like plants grow. The species name mircrodasys, on the other hand, comes from a Latin word that means small and bushy.

Popular varieties and subspecies of bunny ear cactus plants:

  • Opuntia microdasys var. albispina
  • Opuntia microdasys var. pallida
  • Opuntia microdasys var. pallida f. cristata

Holiday Cacti

holiday cacti

Holiday cacti are popular houseplants that deliver attractive blooms in shades of pink, white, and red. Named after the holiday season in which they showcase their beautiful flowers, these holiday cacti are named as Thanksgiving cactus, Christmas cactus, and Easter cactus

People sometimes get confused between Thanksgiving cactus and Christmas cactus because of their close resemblance as they both belong in the Schlumbergera genus. However, it’s quite easy to distinguish when you look at their bloom time and the shape of their stem segments.

Read on to know more about these two types of holiday cacti, as well as the Easter cactus plant. 

Thanksgiving Cactus (Schlumbergera truncata)

Other common names: crab cactus, false Christmas cactus, holiday cactus

Thanksgiving cactus or Schlumbergera truncata plants are native to the tropical forests of Brazil. Often confused with the Christmas cactus (S. bridgesii), this holiday cactus blooms earlier, around the Thanksgiving holiday. 

Sometimes referred to as crab cactus, this outdoor plant features tubular-shaped flowers and leaf-like stem segments with sharp serrated edges. The flowers can be red, pink, purple, or white, depending on the variety. Each plant can grow up to 12 inches in height and up to 24 inches in spread. 

Christmas Cactus (Schlumbergera bridgesii)

Other common names: holiday cactus

Although the Christmas cactus (Schlumbergera bridgesii) may initially look the same as its parent plant, the Thanksgiving cactus, the shapes of their stem segments tell the main difference.

Unlike Thanksgiving cactus with serrated edges, Christmas cactus flaunts flattened stem segments with rounded margins. The flowers are tubular-shaped and often come in vibrant red or fuchsia pink colors.

Also, S. bridgesii blooms later than the Thanksgiving cactus. It typically showcases its beautiful flowers in the late winter or during the Christmas season. The plant can grow up to 10 inches in height and up to 24 inches in width.

Christmas cactus plants are native to the southeastern part of Brazil, particularly to the coastal mountains in the area.

Easter Cactus (Rhipsalidopsis gaertneri)

Other common names: spring cactus, Whitsun cactus, holiday cactus 

Easter cactus (Rhipsalidopsis gaertneri), or otherwise known as Hatiora gaertneri, is a perennial cactus that can grow up to 25 inches or 63 cm in height and up to 30 to 40 cm in diameter.

As with the other holiday cacti, the Easter cactus is endemic to southeastern Brazil. It flaunts flattened stems that are divided into oblong or elliptic segments with smooth edges and small, soft hairs in between.

These leaf segments are pale green and darken in color as they age. Each segment can grow up to 3 inches long and 1 inch wide.

The flowers, which usually measure 4 to 5 cm long and 4 to 7.5 in diameter, bloom in the late winter or early spring. The flowers of Easter cactus are broader than those of the Thanksgiving cactus and Christmas cactus. The color ranges from crimson red to white, lavender, and oranges, depending on the variety.
