Myrtillocactus geometrizans: Bilberry cactus
This cactus, known as the bilberry cactus or “blue candle”, is a native of the
deserts of northern and central Mexico. It is a shrubby cactus growing to around
4 meters in height, and branches strongly as it ages. Mature plants are generally
much taller than most other plant species found in the region, making the bilberry
cactus a defining feature of the landscape. In some areas, entire forests of these
cacti are found.
This cactus has the bluish-green color and waxy surface typical of the species. This
waxy layer acts as a sealant, preventing vital water from evaporating in the hot,
dry air.
Our Myrtillocactus blooms regularly each spring. For such an imposing plant,
its flowers are quite small – just 3 centimeters long at most. They usually appear
in small groups around the needles.
These flowers develop small, thornless fruit. Dark red or violet, they are similar
in size and appearance to blueberries or bilberries, explaining how the cactus got
its name. These fruits have a sweet, pleasant taste and are edible. They are harvested
in the wild in Mexico and sold in markets as garambullos. They can be eaten fresh
or dried like raisins, and are also popular in ice cream and cakes.
