Agave titanota 'Ashura'
Agave titanota 'Ashura' is a selected cultivar of Agave titanota originating in Taiwan. Its appeal lies in bluish-white, relatively short leaves lined with bold white teeth that give each rosette a striking presence among titanota cultivars. The identifying feature to look for is its spine arrangement: the secondary spine often grows larger than the main spine and curves downward, a trait known as a 'reverse spine,' also seen in cultivars like Tarantula and Maryu. Considered suitable for intermediate growers, Ashura is a perennial that rewards attentive care over the long term. While a flowering rosette will eventually die back, the plant lives on through offsets that emerge around its base, letting the clump renew itself over time.

Agave titanota 'Ashura' key facts
- Growing Difficulty
- Intermediate
- Lifespan
- Perennial; the flowering rosette dies and offsets carry on
- Size
- Titanota rosettes range from 30 to 90 cm across (little data per cultivar)
- Watering
- Light feeder; a little slow-release fertiliser in the growing season is enough
- Light & Placement
- Likes strong light and airflow; in poor light the leaves stretch, so indoors use an LED grow light and a fan.
- Watering
- Dislikes summer humidity, so keep on the dry side; in winter water about once a month.
- Temperature & Winter
- Tender; about 0°C is the minimum it survives. Winter it indoors in a sunny spot.
- Soil & Repotting
- Free-draining mix; divide offsets to propagate.
- Notes
- Many cultivars have pale leaves and white teeth; check for large, downward-pointing secondary teeth on the actual plant.
About Agave titanota 'Ashura'
A Taiwan-bred Agave titanota cultivar with bluish-white leaves, bold white teeth, and downward-curving 'reverse spines.' An intermediate-level perennial that renews itself through offsets.
7 things to know before growing Agave titanota 'Ashura'
1Placement & Sunlight
Ashura thrives in a bright, well-ventilated spot. Gradual acclimation to strong outdoor sun helps bring out its bluish-white leaf color, but moving a plant straight from shade into full summer sun can cause leaf scorch, so increase light exposure gradually.
2Watering Basics
Water only once the soil surface has dried out completely. Because the fleshy leaves store moisture, overwatering easily leads to root rot. Space out watering even further during cooler months.
3Choosing Soil
Well-draining soil is essential for keeping Ashura healthy. Mixing pumice or perlite into a commercial succulent or cactus potting mix improves drainage and reduces the risk of root rot.
4When to Repot
Repot when roots become crowded in the pot, ideally just before the plant enters its active growing period. Gently remove old soil and trim away any damaged roots before placing the plant in fresh soil to reduce stress on the root system.
5Seasonal Care
During the active growing season, give the plant plenty of light and moderate watering; as it approaches dormancy, cut back on water to help the rosette firm up. Frost and prolonged rain can damage the plant, so if you keep it outdoors, reconsider its placement as the seasons change.
6Choosing a Plant
When choosing an Ashura, look at the bluish-white leaf color, the size of the teeth, and whether the 'reverse spine' trait is present, where the secondary spine grows larger than the main spine and curves downward. Also check that the leaves are free of damage or discoloration and that the growing point at the center of the rosette looks healthy.
7Renewal Through Offsets
Like other agaves, once an Ashura rosette flowers, that individual rosette will die back. However, offsets that form at the base can be grown on to renew the plant, allowing you to continue enjoying its characteristic features over the long term.
Frequently asked questions about Agave titanota 'Ashura'
- Q.How is Ashura different from Tarantula or Maryu?
- A.Like Tarantula and Maryu, Ashura tends to show a 'reverse spine' where the secondary spine grows larger than the main spine and curves downward. What sets Ashura apart is that it's a selection bred in Taiwan, though individual plants can vary in appearance.
- Q.Is Ashura suitable for beginners?
- A.Ashura is generally considered better suited to intermediate growers. Anyone comfortable with basic agave care, good light, well-draining soil, and careful watering, should be able to grow it, though first-time agave growers may want to review the basics beforehand.
- Q.How large does it grow?
- A.Agave titanota generally reaches a rosette diameter of roughly 30 to 90 cm, though specific data for the Ashura cultivar is limited. Actual growth varies depending on placement and care.
- Q.What is the 'reverse spine' trait?
- A.It refers to the secondary spine below the main terminal spine growing larger than the main spine itself and curving downward. This is one of the key traits used to identify Ashura, and it's shared with cultivars like Tarantula and Maryu.
- Q.What happens to the plant after it flowers?
- A.As with other agaves, the rosette that flowers will die back afterward. If offsets have formed at the base, though, they can be grown on to carry the plant, and its Ashura characteristics, forward.
