Dracaena zeylanica

Dracaena zeylanica origin and former name

Dracaena zeylanica is native to southern India and Sri Lanka, where it grows at low elevations in dry, gravelly ground. It was formerly known as Sansevieria zeylanica. The current name Dracaena zeylanica was published in 2017 after DNA studies showed that Sansevieria belongs within Dracaena. “Zeylanica” is also used in the plant trade for some other cultivated snake plants, so older labels can refer to different plants.

Dracaena zeylanica indoor care

• Light: Give it bright indirect light. A position a little back from a bright window usually works well.
• Water: Wait until the potting mix has dried well and the pot feels noticeably lighter. Water thoroughly, then let the excess drain.
• Potting mix: Use a free-draining cactus or succulent mix, or loosen houseplant mix with grit or fine gravel. Choose a pot with drainage holes.
• Temperature and humidity: Aim for about 15–24 °C. Average household humidity works well. Keep a little air moving around the foliage.
• Feeding: Use a diluted liquid houseplant or cactus fertiliser about once a month while new growth is active.
• Repotting: Repot when roots have filled the container or rhizomes begin to push against the pot. Move up only one pot size.
• Propagation: Divide established offsets or root healthy leaf sections.
• Safety: Keep it out of reach of pets and young children that may chew plants. Eating the leaves can be harmful, and the sap may irritate skin.

Dracaena zeylanica health problems

• The leaf base turns soft or yellow: The roots or rhizomes may be rotting after staying wet for too long. Use a clean, disinfected tool to cut back to firm healthy tissue, discard all rotten material and repot the healthy plant into fresh, free-draining mix.
• Leaves grow long, weak or begin to lean: Long, weak growth often points to insufficient light. Move the plant to a brighter position and increase the light gradually.
• Leaves wrinkle or pucker: Wrinkling can mean the potting mix has become too dry. Check the mix and lift the pot; if the mix is dry and the pot feels light, water thoroughly and let the excess drain.
• Pale or bleached patches develop: Sudden strong direct sun can burn the leaves. Move the plant back from harsh midday sun, then build up direct light slowly.
• Fine webbing or white cottony pests appear: Look closely for spider mites or mealybugs. Move the plant away from others, remove visible pests and use an indoor-plant treatment labelled for the pest you find. Follow the label for repeat applications.

If the cause is unclear, send us clear photos of the whole plant, the affected area and the potting mix.

Dracaena (Sansevieria) zeylanica is toxic to people and pets

• Keep this plant away from children, cats and dogs.
• It contains saponins that can irritate the mouth and digestive tract.
• Chewing may cause drooling, vomiting, stomach pain, reduced appetite or weakness. Contact a veterinarian or medical professional if symptoms develop.

Why do both Sansevieria zeylanica and Dracaena zeylanica appear?

Dracaena comes from Greek drakaina, meaning a female dragon. The epithet zeylanica means “from Ceylon”, the historical name for Sri Lanka.

Carl Linnaeus established the genus Dracaena in 1767 in Mantissa Plantarum, page 9; Domenico Vandelli had proposed the name.

Carl Linnaeus first described it as Aloe hyacinthoides var. zeylanica in 1753 in Species Plantarum, page 321. David Mabberley later placed it in Dracaena as Dracaena zeylanica in 2017 in Mabberley’s Plant-book, edition 4, page 1101.

Sansevieria remains common in horticulture. Pei-Luen Lu and Clifford Morden showed that it belongs within Dracaena in a 2014 DNA study in Systematic Botany, volume 39. Kew’s World Checklist treats Sansevieria zeylanica as a synonym of Dracaena zeylanica.
