Get ready to smarten up your plant collection with a unique and eye-catching variety of hedgehog cactus (Echinocereus genus)- the Echinocereus coccineus also known as the scarlet hedgehog cactus, claret cup cactus, and kingcup cactus. It is a variant of Echinocereus triglochidiatus, that is known for its clusters, bright red/orange flowers, spine cover, and flabby stems.  

The hedgehog cactus is named for its spiky, cylindrical shape, which resembles that of a hedgehog. The plant features dense clusters of spines that grow from the top of the plant and are arranged in a radial pattern, giving it a distinctive appearance. As it grows older, its yellow spine turns grey. 

This little hedgehog cactus is a total survivor - not only is it super cold, hardy, and long-lived, but it also manages to thrive where other plants fear to tread. In mid-spring, it produces bright scarlet flowers that are an absolute magnet for hummingbirds, making this cactus the ultimate backyard wildlife attraction. Plus, after those gorgeous blooms fade away, the plant produces delicious red fruits that are totally edible. 

This evergreen beauty explains with clumps boasting well over 300 members of this genus and stems reaching up to 24 inches tall and 10 inches wide, this spiny hedge cactus is sure to be the talk of your garden or indoor space. From its light requirements to water needs, this plant is relatively easy to care for.  

If you're looking for something out of the ordinary to add some flair to your space, look no further than this Echinocereus coccineus!

Watering Needs

Scarlet hedgehog cactus prefers well-draining soil and should be watered sparingly, allowing the soil to dry out between watering. During the growing season, which typically occurs in the spring and summer, the hedgehog cactus should be watered once every 2-3 weeks. 

In the winter month, when it is in the dormant phase, watering should be reduced to once a month or 4-6 weeks. On the other hand, if there is a severe drought or you forget to water them for over a couple of months during the summer, it can cause discoloration and shriveling as it consumes more of the water in its interior. 

Remember, the soil is fast-draining so that any excess water doesn't get into the root zone, as this can lead to root rot and fungal infections. Overall, Echinocereus cactus are well equipped for handling drought - just don't water them too frequently!  

Light Requirements 

Providing enough light for these desert cacti is one of the most important aspects of their care. It is important to grow this hedgehog cactus in areas that receive at least 4-6 hours of filtered light or partial shade every day to keep them happy. It can tolerate brief rays of direct sunlight, though. New plants can get burned in the full sun as they were probably grown in a greenhouse; therefore, gradually increase their exposure to sunlight. 

If indoors, place your cactus directly in front of a west- or south-facing window with a sheer curtain that can provide the ideal amount of light. If they don't receive enough light, their stems may grow leggy and become paler, and their spines will shorten, so make your cactus happy and give it plenty of light. 

Optimal Soil & Fertilizer Needs 

Use well-drained soil that is designed specifically for your hedgehog cactus. These specialty soil mixes have been precisely developed to imitate well-draining desert soils. Commercial cactus soil is affordable and available online or at Home Depot. We believe the best option is to use our specialty cactus potting mix that contains over 5 natural substrates and organic mycorrhizae to promote the development of a strong root system that helps your Echinocereus cactus to thrive.   

When it comes to fertilizing, remember that less is more. A small amount of natural fertilizer once a year in spring will do wonders for your plant's health and growth. Using balanced fertilizers (5-10-5) of NPK also ensures that other beneficial compounds and microbes are added to the soil without the use of harsh chemicals. However, it is important to avoid over-fertilizing, as this can lead to root burn and other issues.

Hardiness Zones & More

Hailing from arid or semi-arid desert regions, the hedgehog cactus typically grows indoors. If you live in USDA regions 8 to 11, you can also grow these cacti outdoors year-round, but they are mild frost-tolerant, so you should plant them indoors or put them in a pot and move them indoors during the winter if you live outside of these regions.  

Keep your scarlet hedgehog cactus away from cold, drafty windows and air vents if you are growing it indoors in a cold climate. Remember, prolonged frost can cause this stunning cactus to become discolored, wilted, and mushy and can lead to root rot. 

If this hedgehog cactus has already been exposed to a severe frost, it's important to remove any damaged or discolored parts and allow the plant to recover in a warm, dry environment.
