Brazilian Blue Cactus (Pilosocereus azureus)

Electric-blue ribs, golden spines, and fast upright growth make this a showpiece indoors or out.

Growth Habit: Columnar, fast-growing Bloom Season: Summer (night-blooming) Dormancy: Winter Sun Exposure: Full sun to very bright light Soil Needs: Fast-draining cactus mix with grit Hardiness Zones: 9b–11 (protect from frost) Native To: Brazil

Pilosocereus azureus is prized for its rich blue skin that gets brighter with strong light. The ribs are neatly lined with golden spines, giving striking contrast. It grows quickly with heat and sun, making it a great statement plant for bright windows, patios, or warm gardens in frost-free areas. With the right care, your cutting will root and take off.

What you’ll receive:

  • Unrooted 6–9 inch cutting of Brazilian Blue Cactus
  • Cutting is healthy and calloused for shipping (no roots yet)
  • No soil or pot included
  • Natural color, markings, or small scars may be present

After Arrival

Carefully unpack your cutting. The base may look dry; that is normal. Set the cutting in a dry, shaded, airy spot for 1–2 weeks to finish callousing. Do not water during this period. Once the cut end is firm and dry, pot it in dry cactus soil and keep in bright shade while roots form.

Transplant Tips

When potting, bury 1–2 inches of the calloused end in dry mix and stake if needed to keep it upright. Wait 7–10 days, then begin light watering. Keep warm (70–90°F) for faster rooting. In cold weather, grow indoors and protect from frost.

Cactus Care

After Arrival
Unpack your cutting carefully. The base may look dry this is normal. Allow it to rest in a dry, shaded spot for 1–2 weeks so the cut end can fully callous. Do not water during this time. Once ready, pot the cutting in dry cactus soil.

Light
Thrives in full sun and very bright light. Indoors, place by a south- or west-facing window. Outdoors, acclimate slowly to direct sun to avoid sunburn.

Watering
Do not water until after the cutting has been potted for at least a week. Start with a small drink, then let soil dry fully between waterings. Water more once new growth appears, this means roots have formed.

Soil and Pots
Use a gritty, fast-draining mix—cactus soil with added pumice, perlite, or coarse sand. Always plant in a container with a drainage hole.

FAQ
  • How long will it take to root? Most cuttings root within 4–8 weeks when kept warm and dry with bright light.
  • Will it keep its blue color indoors? It will stay blue but the color intensifies with strong sunlight. Outdoors in full sun shows the richest color.
  • Can it survive cold winters? It is not frost-hardy. Keep above 40°F, or bring indoors during winter in colder zones.
  • When will it flower? Mature plants produce large, white, night-blooming flowers in summer. Young cuttings may take several years before flowering.
