Agave americana 'Mediopicta Alba', known in Japanese as Kegon, is a mid-variegated form of Agave americana with a broad creamy-white stripe running down the center of each blue-green leaf. It grows more compactly than the species type, yet still develops into a substantial rosette—typically 90 to 120 cm tall and 120 to 180 cm wide at maturity—with its bold white striping visible from a distance. It's considered an easy, beginner-friendly agave, making it a great entry point into growing agaves. Flowering takes roughly a decade to occur, and once a rosette blooms it will die back, but the plant carries on through offsets that form around its base. It's a striking agave whose slow, gradual growth rewards patience over the years.

Agave americana 'Mediopicta Alba' key facts
- Growing Difficulty
- Beginner-friendly
- Lifespan
- Flowers after about ten years; the flowering rosette dies and is replaced by offsets
- Size
- 90-120 cm tall, 120-180 cm wide (mature, in the ground)
- Watering
- Light feeder; a little slow-release fertiliser in the growing season is enough
- Light & Placement
- Full sun. It grows large, so give it room in the ground, away from paths.
- Watering
- Very drought tolerant; plants in the ground need little or no watering. In pots, water after the mix dries out.
- Temperature & Winter
- A US grower rates it hardy to around -9°C. In cold regions grow it in a pot and keep it out of frost.
- Soil & Repotting
- Use a free-draining mix. It offsets slowly; propagate by division.
- Pests & Cautions
- In the US it is noted as a favourite of the agave snout weevil. Teeth and tip spines are sharp and the sap can irritate skin, so wear gloves.

7 things to know before growing Agave americana 'Mediopicta Alba'
1Give It Full Sun
This agave thrives with plenty of direct sun and good air circulation, ideally grown outdoors in a bright spot. Insufficient light can dull the leaf color and make the white variegation less vivid, so choose the sunniest position available.
2Water Sparingly but Deeply
Like most agaves, it stores water in its thick leaves and tolerates dry conditions very well. Let the soil dry out completely between waterings, then water thoroughly—avoid keeping it consistently moist. Cut back even further on watering during winter.
3Use Fast-Draining Soil
Because it dislikes staying wet, well-draining soil is essential. A commercial succulent or cactus mix, or a blend of akadama and pumice, works well. Add drainage material at the bottom of the pot so excess water never pools around the roots.
4Repot During the Growing Season
Spring through early summer, when growth is most active, is the best time to repot. Once roots fill the current pot, move up to a slightly larger one with fresh, well-draining soil. If planting in the ground, allow enough space in advance, since mature plants can spread 120 to 180 cm wide.
5Protect It in Winter
While reasonably tolerant, it still benefits from winter protection in colder regions. Move potted plants under eaves or to a bright indoor spot away from frost, and mulch around the base of ground-planted specimens to guard against cold snaps.
6Plan for Its Mature Size
Although more compact than the straight species, this is still a large agave that can reach 90 to 120 cm in height and spread 120 to 180 cm wide when grown in the ground. Choose a planting spot with plenty of clearance from pathways and structures to accommodate its eventual size.
7Check the Variegation Pattern
The width and pattern of the central variegation can vary noticeably from plant to plant. When choosing one, check that the creamy-white stripe runs evenly down the center of the leaves and that the foliage is free of damage or discoloration.
Frequently asked questions about Agave americana 'Mediopicta Alba'
- Q.Is this agave suitable for beginners?
- A.Yes, it's considered a beginner-friendly agave in terms of care difficulty. As long as you provide good sun and well-draining soil, it needs no special treatment to grow well.
- Q.How large does it eventually grow?
- A.Mature, ground-planted specimens reach roughly 90 to 120 cm in height and 120 to 180 cm in width. It tends to stay somewhat more compact than the straight Agave americana species.
- Q.Does this agave flower?
- A.Flowering typically takes around a decade to occur. The rosette that blooms will die afterward, but offsets form around its base to carry the plant forward.
- Q.Can it be grown indoors?
- A.Since it needs plenty of light, outdoor placement in full sun is generally best. If grown indoors, place it in the brightest spot available, such as near a window, to avoid insufficient light.
- Q.How often should I water it?
- A.Water thoroughly only after the soil has dried out completely. Because its thick leaves store water, it tolerates dryness well, and watering should be reduced even further during winter.
