Crossandra problems

Crossandra infundibuliformis is commonly called firecracker flower or firecracker plant. The name refers to its seed capsules, which can split open when mature and wet.

Give it bright filtered or indirect light, or gentle morning sun with some shade from intense afternoon heat. It tolerates full sun in mild conditions, while deep shade can reduce flowering.

Check the top inch of potting mix and water when it begins to dry. Keep the root ball lightly moist during active growth, let excess water drain, and water less when the plant grows slowly in cool or dim conditions.

Yes. Grow it in a warm room with bright indirect light, an open-draining pot, and enough humidity to prevent the air from becoming very dry. Bring outdoor plants in before cold weather; temperatures below about 55°F (13°C) can damage leaves.

NC State Extension tags Crossandra infundibuliformis as non-toxic to cats and dogs, and also lists it as non-toxic to horses. Safety for rabbits, birds, turtles, and tortoises was not verified here; discourage chewing and ask a veterinarian about a concerning ingestion.

Propagate Crossandra from healthy stem or root divisions during active growth.

Use use a fertile, organic-rich but free-draining potting mix. Crossandra prefers slightly acidic conditions and steady moisture, while good drainage protects its roots from waterlogging. A peat-free container compost with added perlite or another open-textured material is a practical choice indoors. A good mix includes Use a peat-free, organic-rich potting compost in a container with open drainage holes., Add perlite or pumice if the mix compacts or stays wet too long., Do not leave the pot standing in water after irrigation. Moist but well-drained; avoid saturated beds and pots without drainage holes. Target soil pH around Slightly acidic is preferred; sources place the target near pH 5.8–6.5, but avoid adjusting a healthy mix without a soil test.
