Features & Attributes

Chilean Cactus's attractive succulent narrow leaves emerge chartreuse, turning bluish-green in color throughout the year. It features bold white cup-shaped flowers along the branches from mid spring to mid fall.

This is a multi-stemmed evergreen houseplant with a narrowly upright and columnar growth habit. Its wonderfully bold, coarse texture is quite ornamental and should be used to full effect. This plant should never be pruned unless absolutely necessary, as it tends not to take pruning well.

Planting & Growing

When grown indoors, Chilean Cactus can be expected to grow to be about 3 feet tall at maturity, with a spread of 24 inches. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 100 years. This houseplant will do well in a location that gets either direct or indirect sunlight, although it will usually require a more brightly-lit environment than what artificial indoor lighting alone can provide. This is a unique plant in that it requires extremely dry, well-drained soil, and it will die if left in standing water for any length of time - in fact it will suffer if it is over-watered. The soil should be allowed to go completely dry to the touch an inch or two deep for prolonged periods, and it may only need watering once every few weeks. Be aware that your particular watering schedule may vary depending on its location in the room, the pot size, plant size and other conditions; if in doubt, ask one of our experts in the store for advice. It is not particular as to soil type or pH; an average potting soil should work just fine.

There are many factors that will affect the ultimate height, spread and overall performance of a plant when grown indoors; among them, the size of the pot it's growing in, the amount of light it receives, watering frequency, the pruning regimen and repotting schedule. Use the information described here as a guideline only; individual performance can and will vary. Please contact the store to speak with one of our experts if you are interested in further details concerning recommendations on pot size, watering, pruning, repotting, etc.
