8 Popular Red Cactus Flowers
Cacti is a succulent that thrives in warm weather with ample direct sunlight.
However, not every cactus will bear exotic-looking red flowers, and only a handful of cacti species will likely bloom with signature red flowers.
Some popular cacti species that bear red flowers include Echinopsis, Cleistocactus, Echinocereus, Disocactus, Opuntia, and Ferocactus.
Remember, the red cacti flowers will only begin flowering once they’ve matured, taking one to ten years.
Let us look at some of the unique cacti that bear red flowers.
1. Prickly Pears
Prickly Pears are a variety of Opuntia, a flowering cactus species native to North America.
Did you know its red cup-shaped flowers will only last a day before beginning to form a pear-shaped fruit?
This one is drought-tolerant and can survive in many substrates; therefore, they are often kept as ornamental houseplants.
It will grow up to 2-5 feet in height depending on where you grow it, pot or ground.
Remember, it may take over four years before it starts blooming and producing edible fruits.
Fertilize your Prickly Pears monthly with a 5-10-10 solution and provide ample direct sunlight, but cut back on everything in fall and winter to ensure dormancy.
2. Claret Cup
Claret Cup (Echinocereus Triglochidiatus) is a cactus native to the southwestern US and Mexico, such as Utah, Colorado, Texas, and New Mexico.
The typical desert flowering species will thrive outdoors in full sun with regular watering in hot months.
Also known as Scarlet Hedgehog, it boasts scarlet red blooms about 1-2 inches wide with multiple petals that turn into small, round, green fruits.
The Claret Cup is a shorter cactus but will extend 3-4 feet across when provided with ample ground area.
Moreover, these cacti are not heavy feeders, requiring fertilizing only once a month in spring.
3. Orchid Cactus
Orchid Cactus (Disocactus ackermannii) is an epiphytic cactus belonging to the tropical forests of Veracruz and Oaxaca, Mexico.
These plants thrive in indoor environments with dappled sunlight and regular watering every two weeks in spring and summer.
Moreover, provide high-phosphorus fertilizer every two weeks in spring and summer to boost blooms.
They will grow about 10 feet in height when provided with the optimal growing condition.
4. Peanut Cactus
Peanut Cactus (Echinopsis chamaecereus) is native to Mexico and South America and is known as one of the rarest cacti.
However, the profusion of stems will form a large cluster, making it look wider.
The cactus blooms every spring or summer with red or orange flowers measuring about 2 inches wide.
They seem prickly but soft to the touch and are pretty popular as ornamental plants grown outdoors and indoors.
Remember, it requires full sun for about 6-8 hours every day in spring and summer, with watering every two weeks.
Besides, it blooms in cooler temperatures.
5. Fire Barrel Cactus
Fire Barrel Cactus (Ferocactus gracillis) is a small barrel-shaped cactus hailing from Northwestern Mexico.
It gets its name from the striking red coloration of its spines and flowers and its barrel-like shape.
These flowers would only appear in summer; unlike other cacti, they will retain flowers for up to six weeks.
These flowers will gradually turn into fruit buds which can be harvested from late November to March.
An extremely slow grower will take ages before reaching a full height, usually 3-4 feet.
Choose a sunny location with well-draining cacti soil and water once a few weeks to keep it looking healthy.
6. Fishhook Cactus
Fishhook barrel cactus (Ferocactus wislizenii) is commonly called a hook-spine species because of its spikes that resemble fish hooks.
They originally grow along desert washes from southwestern North America to the Caribbean.
You can quickly identify it by its thick, usually 2 feet wide, barrel-shaped body and hooked spines.
These flowers usually appear in the fall (September and October).
These cacti will hardly grow over 6 inches, making them perfect ornamental cacti to grow outdoors and indoors.
Keep it in bright to high light spots, near a south or west window, but away from direct sunlight to avoid sunburn.
However, do not confuse it for Hook Cactus (Echinopsis cinnabarina), which has a round-to-globular stem.
7. Kingcup Cactus
Kingcup Cactus (Echinocereus triglochidiatus) is native to the southwestern US and northern Mexico, where it grows in the desert to rocky slopes.
It is mainly grown for showy flowers that display an orange-red to scarlet shade from late spring to July.
However, these blooms will last only 2-3 days before collapsing from fruit buds.
One way to identify Kingcup cacti is from their dense spines that give a wooly appearance.
Like every cactus, it needs good drainage and direct sunlight to maintain a healthy appearance. However, keep it dry and cool with ample diffused sunlight to boost flower production.
8. Christmas Cactus
Christmas Cactus (Schlumbergera x buckleyi) is unlike other cacti that display pointy spikes.
Originating in the coastal mountains of southeastern Brazil, these cacti grow in the shade with high humidity.
The holiday cactus will bloom in October, continue until November, and display red and purple flowers.
Do not confuse Christmas Cactus with Thanksgiving and Easter cacti, which grow at different times and display slightly different-looking stems.
