Last 2005, I bought my Myrtillocactus geometrizans from Rose, a dealer of cacti and succulents. Initially, the plant had lots of erect stems with hazy blue patches. Hence, its common name Blue Candle, Blue Myrtle Cactus,or Whortleberry Cactus. When I repotted it in a sandy-loam soil, the cactus later on grew into a shrub about 3 feet tall. Its columnar stems have reddish-radial spines and a black central spine along its 5 ribs (some stems have six ribs). Also, some stems mutated into a cristate form.
In the photo above, I planted several erect side shoots of the Blue Candle in a small pot. One of the blue stems had an abnormal growth which added an interesting touch to this plant piece. I intended to put this potted cactus on a table so I added some small stones and a red coral for finishing touches.
Another variety of my Myrtillocactus geometrizans came from my plant buddy Baby Yu of Baroy, Lanao del Norte. The mother plant of this specimen has stems with four ribs; I don’t know what environmental factors in my garden affected it to produce stems with five ribs. Anyway, the single stem in the photo above is about 20 inches long and 4 inches in diameter. White markings are present on each side of this variety.
