Agave victoriae-reginae 'Hyouzan' (White Rhino)
Agave victoriae-reginae 'Hyouzan' (White Rhino) is a variegated form of the classic victoriae-reginae, with wide, pure white margins framing its deep green leaves. Known abroad as 'Albomarginata' or White Rhino, it keeps the tightly geometric, triangular leaf pattern that makes the species so recognizable, now set off by crisp white edges. Growth is slow and offsets are infrequent, so building up a cluster takes patience. Like other agaves, it is a perennial whose rosette flowers once and then dies back, with offsets carrying the plant forward. Because of its unhurried pace, it is best suited to growers with some agave experience.

Agave victoriae-reginae 'Hyouzan' (White Rhino) key facts
- Growing Difficulty
- Intermediate
- Lifespan
- Perennial; the flowering rosette dies and offsets carry on
- Size
- Rosettes 25-30 cm tall and about 38-45 cm wide
- Watering
- Light feeder; a little slow-release fertiliser in the growing season is enough
- Light & Placement
- Sun to bright light shade; the pale variegated margins scorch easily, so soften the strongest midsummer sun.
- Watering
- Prone to rot if kept wet; water only when the mix is thoroughly dry, and very sparingly in winter.
- Temperature & Winter
- A US grower finds it unharmed to about -4°C (the plain species is hardier); protect from frost and cold rain in winter.
- Soil & Repotting
- Use a free-draining mix to prevent rot; it grows slowly, so repot only when pot-bound.
- Notes
- The Hyouzan name also covers the 'Hanno' type and a centre-variegated form; check where the variegation lies on the actual plant.
About Agave victoriae-reginae 'Hyouzan' (White Rhino)
A variegated Agave victoriae-reginae with bold white leaf margins, known abroad as White Rhino. Slow-growing with few offsets, it suits growers with some agave experience.
7 things to know before growing Agave victoriae-reginae 'Hyouzan' (White Rhino)
1Sun and Airflow
Agave 'Hyouzan' thrives in full sun with good air circulation outdoors. If leaf scorch is a concern, providing light shade during the height of summer can help.
2Watering
Water thoroughly only after the soil has fully dried out. Avoid letting water sit in the saucer, as overly wet conditions can lead to root rot.
3Soil
A fast-draining succulent or cactus mix suits this agave well. Blending in hard akadama or pumice improves drainage and supports healthy root growth.
4Repotting
Growth is slow, but once roots fill the pot it's time to move up to a slightly larger one. Repotting during the warmer growing season puts less stress on the plant.
5Winter Care
Some outdoor cold exposure can help the rosette form tightly, but hard frost and freezing should be avoided. Depending on your climate, consider protection or bringing the plant indoors in winter.
6Choosing a Plant
The width and pattern of the white margin can vary from plant to plant. Look for a specimen with a crisp, well-defined boundary between the green and white portions of the leaf.
7Growth Pace
This variety grows slowly and produces few offsets, so it doesn't multiply quickly. Approaching it with patience makes for a rewarding long-term project.
