Dracaena trifasciata ‘Hahnii Golden Edge’

Origin and selection history of Dracaena trifasciata ‘Hahnii Golden Edge’

Wild Dracaena trifasciata grows in southern Nigeria, parts of west-central Africa and Tanzania, in tropical areas with a dry season.

It was formerly called Sansevieria trifasciata. The older name for Golden Edge is ‘Hahnii Giltedge’. Sylvan Frank Hahn patented this pale-edged form in 1953 after it appeared in the compact Hahnii line.

Dracaena trifasciata ‘Hahnii Golden Edge’ compact rosette care

• Water: After the mix dries through, water around the rosette until the potting mix is evenly moist, then let it drain. Keep water out of the centre.
• Light: Use plenty of indirect light and keep harsh direct sun off the foliage. Light shade also works for the compact rosette.
• Temperature: If conditions approach 10 °C, move the plant away from the cold source. Keep this compact plant around 18–27 °C and away from cold draughts.
• Humidity: Provide about 40–50% humidity. Keep the air from becoming still around the leaves, for everyday care. Air movement helps the closely packed leaves dry promptly.
• Cooler conditions: Growth slows and the mix takes longer to dry, so water less often.
• Potting mix: Use a coarse, quick-draining succulent mix in a stable pot with drainage holes.
• Feeding: While new leaves and side rosettes are developing, use a light feed about monthly.
• Repotting: Repot when side rosettes crowd the rim or roots fill the container.
• Propagation: Separate rooted side shoots to keep the pale edge. Leaf cuttings produce green Hahnii-type growth.

Dracaena trifasciata ‘Hahnii Golden Edge’ rosette problems and solutions

• Centre leaves soften: Water held in the tight rosette can cause rot in the centre. Check the centre, base and roots. Use a clean, disinfected knife to remove soft areas back to firm, healthy tissue, then discard the rotten pieces. If the base or roots are affected, repot the healthy plant in fresh, free-draining mix. Keep water out of the centre while the plant recovers.
• The whole rosette loosens or collapses: Check the roots. If they are soft and brown, use clean, disinfected scissors to cut back to firm roots, discard the rotten pieces and repot the healthy plant in fresh, free-draining mix. Missing or chewed roots can point to vine weevil larvae in the potting mix. Remove any larvae you find and use a houseplant treatment labelled for vine weevil, following the label directions.
• Dry brown marks along the pale edge: Intense direct sun can scorch the pale edge. Move the plant out of direct sun and keep it in bright filtered light.
• Cottony deposits between tightly packed leaves: Check for mealybugs, isolate the plant and clean the leaf bases carefully. If treatment is needed, use a product labelled for mealybugs and repeat it only as directed on the label.
• Wrinkled leaves with firm roots: If the roots are firm and the potting mix is dry, wrinkling usually means the plant needs water. Water thoroughly and let excess water drain away.

Dracaena trifasciata ‘Hahnii Golden Edge’ 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.

How did the name change from Sansevieria trifasciata to Dracaena trifasciata?

Dracaena comes from Greek drakaina, meaning a female dragon. The epithet trifasciata means three-banded.

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

David Prain first described it as Sansevieria trifasciata in 1903 in Bengal Plants, volume 2, page 1054. David Mabberley later placed it in Dracaena as Dracaena trifasciata 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 trifasciata as a synonym of Dracaena trifasciata.
