When it comes to the blue candle cactus, also known as Myrtillocactus geometrizans, there are several distinct characteristics that make it a popular choice for cultivation in gardens and landscapes around the world. This shrubby or tree-like cactus has a unique appearance that becomes even more pronounced as it ages.
One of the most striking features of the blue candle cactus is its thick stems, which can grow up to 4 inches across (10 cm). These stems are a beautiful bluish-green color, giving the cactus its common name. The color adds a touch of uniqueness to any garden or landscape, making it a visually appealing choice for many gardeners.
The stems of the blue candle cactus are also notable for their ribbed texture. Each stem typically has 5-8 ribs running along its length, adding an interesting visual element to the overall appearance of the plant. This ribbed texture adds depth and dimension to the cactus, making it a standout feature in any garden or landscape design.
Another characteristic of the blue candle cactus is the presence of areoles along the stems. Areoles are small, round, cushion-like structures that serve as the location for spines, flowers, and new growth. In the case of the blue candle cactus, the areoles are particularly important because they bear the spines that protect the plant.
The spines of the blue candle cactus are another defining characteristic. Each areole typically bears 5-9 spines, which can vary in color from black to brown. These spines serve as a defense mechanism for the cactus, deterring animals and humans from touching or damaging the plant. They also add a textural element to the overall appearance of the cactus, enhancing its aesthetic appeal.
In terms of size, the blue candle cactus can reach impressive heights with proper care and cultivation. It can grow up to 20 feet (6 meters) tall, making it a substantial presence in any garden or landscape. However, it is important to note that achieving this height may take several years, as the cactus grows relatively slowly.
The blue candle cactus is a visually striking and unique plant to incorporate into gardens and landscapes. Its thick, bluish-green stems with ribbed texture, presence of areoles, and spines contribute to its distinctive appearance. Additionally, its potential for impressive height adds to its appeal as a focal point or statement piece in any outdoor space.
