Blue Ghost Cactus
A sculptural blue columnar cactus with a ghostly glow. The trade name is used for multiple Pilosocereus species.
We’ll add pictures of our actual nursery specimens and mature examples.
Keep your cactus happy
Give bright light and several hours of direct sun. In South Texas, introduce newly shipped plants gradually; some afternoon shade helps prevent sunburn during their first intense summer.
Water deeply once the mix has dried well and active growth has resumed. Avoid constant moisture, especially during cool weather. New, unrooted cuttings need different watering than established plants.
Great in pots while young — ground only in protected sites
A heavy, well-draining container makes freeze protection easier. Mature columns may outgrow a manageable pot and need staking or professional moving; in-ground planting is best reserved for reliably warm, very well-drained locations.
Use a fast-draining, mineral-rich cactus mix and a pot with drainage holes. Don’t leave the saucer full of water.
Blue Ghost is a trade name used for different species, so mature dimensions vary substantially. Expect an upright columnar cactus that can become large; check the exact botanical identity before choosing a permanent landscape site.
Treat as frost-sensitive until the species is confirmed. Move potted plants into a bright protected area before freezing temperatures and avoid winter-wet soil.
Good to know
The blue, waxy-looking stems are especially vivid in side light. This one is all about color and architectural shape.
