What is Cactus?


There are over 170 types of cactus with more than 2,000 types of cactus species. One thing a cactus is not a tree, herb, or flower, but they are part of the plant kingdom. The cacti belong to the Cactaceae family.

While the different cacti are not flowering plants, they can produce flowers. The cactus grows as tall as trees without woody stems. Furthermore, they fall under the succulent genus as they store water in the stems, and the Latin word is kaktos, meaning spiky plant.

An interesting fact is that the spines protect the plant from wildlife and keep them insulated in drought. In addition, the ribbed and waxy stems help to retain water, and photosynthesis takes place at night in the stems.

Still, not all types of cactus have spines, as some have bristles when looking to forest cacti species. Another interesting fact is that cactus plants can grow as old as 100 years outdoors and 15 years indoors.

The different types of cactus you find native to Brazil, Mexico, and central Latin America. In addition, the species can extend to British Columbia and Patagonia. Furthermore, the spines on cacti are the leaves and protect the plant against water evaporation.

You find different types of cactus plants that grow in all shapes and sizes with colorful blooms at various times of the year. The fun part of the cactus is that it can survive on minimal water and is very drought tolerant.

Types of Cactus Plants for Your Home

We have selected some of our favorites for you to grow as indoor plants or landscaping with brief information on what a cactus plant is.

The Christmas Cactus

christmas cactus

The fancy botanical name for the Christmas cactus is Schlumbergera spp. This cactus adds color to any living space when it is cold outside. It is one of the least stereotypical cacti. The cactus also resembles some other cacti like the Easter and Thanksgiving cactus.

Yet, there is a difference in the foliage as the Easter cactus has foliage that looks like lobster or crab claws. The plant grows in the forest in Southeastern Brazil on trees or other plants and objects.

The plant also blooms twice a year under the right conditions, and the bloom cycle is thermo-photoperiodic. What this means is that the temperature with the day length triggers blooming.

You notice the flowers bloom as soon as temperatures fall under 50°F and spend up to 14 hours per day in total darkness.

Fairy Castle Cactus

fairy castle cactus

Acantheocereus testragonus, as botanists call it, looks like a whimsical castle with a display of stems growing at different heights. The fairy castle cactus can grow up to 6 feet tall. Unfortunately, this type of cactus is slowly growing and seldom produces flowers.

Still, some botanists call it the Cereus tetragonus, native to North America. It grows distinct ribs with short, dense spines. As the cactus plant ages, it turns brown, and the clustered tips extend to branch out when they grow.

When the cactus does flower, it only happens at night and displays a large white flower.

Star Cactus

star cactus

Astrophytum asterias is a great plant to grow indoors; it reaches 2 inches tall and spreads 5 inches wide. The star cactus grows spine pads along the ribs and has no prickly spines. The brown, greenish body you see is covered in white scale and provides extraordinary ornamental value.

When the star cactus flowers, it is yellow and has a reddish base. Unfortunately, the cactus is on the endangered list in Texas and is native to Mexico. As a result, the cactus plants have suffered habitat loss, but you can find cactus growers offering them for purchase.

Many growers also call the star cactus the starfish or sea urchin cactus.

Barrel Cactus

barrel cactus

Echinocactus spp. and Ferocactus spp. are native to the North American desert. The barrel cactus can live up to 100 years and only grows 3 feet tall. Many people grow the barrel cactus for their flowers that bloom in red, orange, yellow, or pink.

You can find different types of cacti of this species sold at nurseries. The spines grow long yet dense, and they are sharp. Some of these cactus plants can have a filament covering the spines.

The name is because of the barrel shape, sometimes referred to as the mother-in-law’s cushion. The barrel cacti need a lot of sun with minimal watering.

Old Lady Cactus

The Mammillaria hahniana is a great beginner plant that needs no frequent watering. Some gardeners call it the powder puff cactus, with white spines running down the body.

The cactus grows in Mexico and produces small round offsets clustering around the mother plant. While the cactus is easy to grow and looks fluffy, it is best not to touch it because its spines are sharp.

When the old lady cactus blooms, the flowers are red or white, and flowers are in summer.

Moon Cactus

These cacti are loved for their bright colors as they are grafted with two different species. The bottom part comes from the Hylocereus species.

You see the scion known as Gymnocalycium mihanovichii displayed in red, yellow, pink, white, or orange.

The moon cactus scion lacks chlorophyll and needs the cactus beneath for nutrients. These cacti remain small, under six inches tall. Still, the moon cactus’s lifespan is short compared to other cacti.

LadyFinger Cactus

Unfortunately, the cactus is not cold-hardy and best kept growing indoors.

African Milk Tree Cactus

The Euphorbia trigona is more succulent than a cactus as it is relative to the poinsettia. It does have ribbed long yet fleshy stems similar to the cactus plants and grows maroon leaves on top with spikes along the stems. Yet, it can irritate when your skin comes in contact with the stem.

San Pedro Cactus

san pedro cactus

Echinopsis pachanoi is the fancy botanical name for the San Pedro cactus. You find the cactus growing in its natural habitat in the Andes Mountains. It can grow at elevations between 6,600 to 9,800 feet.

It is an easy-to-grow houseplant but grows fast and is best kept in the landscape in mild climates. The cactus plants are drought tolerant, work well for xeriscaping, and grow well in high rainfall regions.

The important thing is to provide the cactus with well-draining soil to prevent crown and root rot.

Prickly Pear Cactus

prickly pear cactus

Pricky pear cactus belongs to the Opuntia genus and is a cold-tolerant species as several cacti can withstand temperatures below zero degrees. Still, you find them growing in dry, sunny landscaping or indoors in North America. The cactus plants produce flowers in spring and delicious fruit in summer.

You can find dozens of cultivars grown with fleshy lobes and unique spine patterns.

Cholla Cactus

The cactus needs plenty of space to grow with clearance for you to move around the plant. The cactus grows dense spines inside paper sheaths, and some are colorful. For xeriscaped landscapes, it makes an excellent addition in sunny, dry locations.

Feather Cactus

Mammillaria plumosa looks like it is covered in snow with white filaments. The feather cactus makes for a beautiful ornamental display. The filaments provide shade for the plant when the heat is intense in Mexico.

The feather cactus can grow up to three inches tall and 16 inches wide. The best-growing medium for the cactus is a shallow container, and it is best not to water the filaments. You can feed the cactus twice a year with some cactus plant food.

Pencil Cactus

Jumping Cactus

Cylindropuntia fulgida is similar to the cholla cactus and grows loose joints. When people walk past the loose segments, it attaches to them, leaving countless thorns behind. The cactus grows in its natural habitat in Southwest America.
