Is Crown of Thorns a cactus or succulent?

The Crown of Thorns, scientifically known as Euphorbia milii, is often mistaken for a cactus due to its spiny appearance. However, it is actually a succulent plant. As a gardening and landscaping expert, I can tell you that this plant is an excellent choice for a houseplant, thanks to its unique characteristics and adaptability.

Native to Madagascar, the Crown of Thorns can reach impressive heights of up to six feet when given the right conditions. Its spines, which cover the stems and branches, serve as a protective mechanism against herbivores. These spines can be quite sharp, so it’s important to handle the plant with care when pruning or repotting.

The term “succulent” refers to plants that have adapted to arid conditions by storing water in their leaves, stems, or roots. The Crown of Thorns is no exception. Its thick, fleshy leaves are capable of retaining moisture, allowing the plant to survive in dry environments with minimal watering.

One of the reasons why the Crown of Thorns is a popular houseplant choice is its ability to thrive in a range of light conditions. It can tolerate both bright, indirect light as well as lower light levels, making it suitable for various indoor spaces. However, it’s important to note that prolonged exposure to direct sunlight can cause leaf scorching.

When it comes to soil, the Crown of Thorns prefers a well-draining mix. A combination of regular potting soil, sand, and perlite works well to ensure proper drainage. Overwatering should be avoided, as it can lead to root rot. Allow the top inch of soil to dry out between waterings, and reduce watering during the winter months when growth slows down.

In terms of temperature, the Crown of Thorns prefers warm conditions between 65°F to 85°F (18°C to 29°C). It can tolerate slightly cooler temperatures but should be protected from frost. If you live in a colder climate, it’s best to keep the plant indoors or provide it with additional protection during the winter months.

Pruning the Crown of Thorns is necessary to maintain its shape and size. You can use clean, sharp pruning shears to remove dead or damaged branches. It’s advisable to wear gloves during pruning due to the plant’s spines. Additionally, fertilizing once every few months with a balanced houseplant fertilizer can help promote healthy growth.

Personal Experience:
I have had the pleasure of growing a Crown of Thorns plant in my own home, and I must say it has been a rewarding experience. Its spiny appearance adds a unique touch to my indoor garden, and its vibrant blooms are a sight to behold. Despite its spines, I’ve found that with proper handling and care, the plant is relatively low-maintenance.

To summarize, the Crown of Thorns, or Euphorbia milii, is a succulent plant native to Madagascar. Although it resembles a cactus with its spiny appearance, it is not a cactus but rather a succulent. This plant is an excellent choice for a houseplant, thanks to its adaptability, ability to tolerate different light conditions, and its unique beauty. With proper care in terms of watering, light exposure, and pruning, the Crown of Thorns can thrive and bring joy to any indoor space.
