Agave potatorum 'Super Crown'

Agave potatorum 'Super Crown' key facts

Growing Difficulty

Intermediate

Lifespan

Perennial; can be propagated from offsets

Size

Rosette 30-50 cm across

Watering

Light feeder; a little slow-release fertiliser in the growing season is enough

Light & Placement

Sunny, airy spot, but its thin skin scorches easily, so shade it from midsummer sun.

Watering

Keep on the dry side; it dislikes humid summers, so water only when the mix has dried.

Temperature & Winter

Tender: bring it indoors when the minimum is forecast to fall below 3°C.

Soil & Repotting

Free-draining mix; propagate from offsets or by division.

Notes

Often sold alongside Kissho Kan Nishiki; choose by leaf gloss and vivid variegation on the actual plant.

About Agave potatorum 'Super Crown'

Agave potatorum 'Super Crown', a sport from Sota Botanical Garden in Aichi, Japan, features glossy leaves with a vivid cream margin. This intermediate-level agave grows to 30-50 cm across and propagates via offsets.

7 things to know before growing Agave potatorum 'Super Crown'

1. 1Placement and Light

   Keep the plant outdoors in a well-ventilated spot with plenty of light, which helps the cream variegation stay vivid. Because its epidermis is thinner than many agaves, intense midsummer sun can scorch the leaves, so moving it to partial shade during the hottest weeks is a good precaution.

2. 2Watering Basics

   Water thoroughly once the soil surface has dried out, letting water run freely from the drainage holes. The thick leaves store moisture, so the plant dislikes staying wet, and watering intervals should be extended during periods of slower growth.

3. 3Well-Draining Soil

   A fast-draining succulent mix, such as one blending akadama and pumice, suits this agave well. Avoid fine, water-retentive soils, which can encourage root rot.

4. 4Repotting Timing

   Repot in spring through autumn, once the roots have filled the current pot, moving up to a slightly larger container. Since the rosette can reach 30 to 50 cm across, plan to size up the pot every few years as the plant matures.

5. 5Summer Heat Care

   With its thinner epidermis, this cultivar is more prone to leaf damage during intense summer heat and strong sun. Ensuring good airflow and providing shade cloth or partial shade during the hottest part of the day helps reduce stress on the plant.

6. 6Winter Cold Care

   This variety is sensitive to cold as well as heat, and a minimum of about 3°C is the guideline for overwintering. When night-time lows are likely to drop below 3°C, bring it indoors to a bright spot. Reducing watering and keeping the soil on the drier side during cold months helps prevent damage.

7. 7Propagating by Offsets

   As a perennial, it produces offsets at the base as it matures. Once an offset has grown to a reasonable size, separate it from the parent plant, let the cut surface callus over, and then plant it to propagate a new specimen.

Frequently asked questions about Agave potatorum 'Super Crown'

Q.Can beginners grow this agave?

A.This is considered an intermediate-level variety, so it is best attempted once you have some agave-growing experience. Its thinner epidermis makes it more sensitive to heat and cold, so careful attention to placement and watering timing is important.

Q.How is this different from Kissho Kan Nishiki?

A.Super Crown is a sport that arose from the white-margined form of Kissho Kan at Sota Botanical Garden in Aichi, and its cream margin is generally described as more vivid and showy than Kissho Kan Nishiki's. On the other hand, its thinner epidermis makes it somewhat less tolerant of heat and cold.

Q.How large does it eventually grow?

A.The rosette reaches roughly 30 to 50 cm in diameter. Since the plant spreads outward as it matures, it helps to allow some extra room in the pot as it grows.

Q.When does it start producing offsets?

A.As a perennial, it tends to produce offsets at the base once the main rosette matures and becomes well established. Once those offsets grow large enough, they can be separated and grown on as new plants.

Q.What should I watch for in summer and winter?

A.Because the epidermis is thin, both intense summer sun and winter cold require caution. Provide shade or partial shade in summer, and in winter bring the plant indoors whenever lows are likely to drop below 3°C to reduce stress on it.
