Myrtillocactus geometrizans

 

Blue Candle Cactus

Cacti occur in all shapes and sizes. They are extremely well adapted to drought and able to store water within the structure to ensure survival through dry periods. They can be found surviving in the driest places on the planet. Almost all cacti are succulents, and are often grown in greenhouses, particularly in regions unsuited to their cultivation outdoors. They can be grown in the ground or in suitable containers which means that they are suitable as houseplants, being tolerant of the often dry atmosphere. Potted cacti can be moved outside in the warm summer months. Myrtillocactus geometrizans (bilberry cactus, whortleberry cactus or blue candle) is a species of cactus in the genus Myrtillocactus, native to central and northern Mexico. Myrtillocactus geometrizans is a large shrubby cactus growing to 4–5 m tall, with candelabra-like branching on mature plants. The individual stems are 6–10 cm diameter, with five (occasionally six) ribs, with areoles spaced 1.5–3 cm apart. The flowers are creamy white, 2–2.5 cm diameter. The fruit is an edible dark purple berry 1–2 cm diameter, superficially resembling Vaccinium myrtillus (Bilberry or Whortleberry) fruit; both the scientific and English names derive from this resemblance.[2] It is a popular species in cultivation, where young plants commonly remain unbranched for many years. The fruit is edible, and sold for consumption in Mexico.[2] This Cactus is fast growing, and is often used as grafting stock because of this. With favourable conditions it can reach heights of up to 15 feet.[3] Alternative common names include:Garambullo, Bilberry Cactus, Blue Flame, Whortleberry Cactus, and synonyms include Cereus geometrizans, Cereus pugioniferus

Planting outdoors

From Early Spring TO Late Spring

Only a select few cactus will survive outside in temperate climates, because of winter rains and low temperatures. In selecting plants for use outside, one must look at the habitat from which the plant originates. It must have sun most of the day. Morning and afternoon sun is better than two o clock sun. The area should have very good drainage, this is more important in the winter than the summer. Most cactus are not killed by the cold, but when the water inside the plant freezes it expands and splits the outer layer of skin, this allows bacteria to enter the plant and kill it.

 

Propagation

From Early Spring TO Late Summer

The habit of the cacti and succulents will give you an indication as to which method of propagation will suit it; Branching habits can have their side shoots and stem removed to produce stem cuttings. Columnar types are propagated by stem cutting. Clump-forming species readily produce offsets which can be lifted and divided. Some fleshy leaves make great leaf cuttings, which are so simple and great fun.

 

Planting in pots

From Early Spring TO Late Winter

Potting mixes can be made by mixing one part potting mix, one part washed sand & one part course fill (rocks, pumas, broken pots, etc.) Don`t worry too much drainage is better than not enough. When planting the cactus never dig a deep hole down in the potting mix. You want the plant to set on top of the potting mix, this allows the roots to go down to get moisture with out the plant setting in wet soil. A potted cactus will live and flower in the house if given enough light, place the plant near a bright lighted window, where it will receive light most of the day. On the patio is different place the cactus in a partly shaded area until it become accustom to the sun.

 

Propagation by cuttings and offsets

From Early Spring TO Late Winter

Most cuttings require time to dry and produce a callus on the wound, this can take from a week to a day depending on size and type. Use John Innes No 1 with up to 30 percent by volume of added grit and keep the compost on the dry side to prevent the cutting rotting off. Always check what your individual specimen will require.

 

Propagation by seed

From Early Spring TO Late Spring

Many species can also be grown from seed; Use John Innes No 1 with added grit or sand for added drainage. Sow the seed in spring. Large seed will need a covering of one to two times the depth of the size of the seed. Small fine seed should not be covered, but mix the seed with a little sand to help with an even distribution. Water with a misting bottle or a watering can with a fine rose and cover the pot with a sheet of glass or plastic bag. Keeping them at 21°C in partial shade. Allow air into the pot daily by removing glass or plastic bag and wiping off condensation. Keep moist but not overly wet. Pot on seedlings when they are big enough to handle. It can take up to 12 months for them to reach this stage.
