Name: agave (Agave spp, Agave attenuata).
Plant type: evergreen succulent.
Height: generally less than 1.5m × 1m.
Foliage: large, fleshy, bluey-green, broad, sword-like.
Climate: tropical and sub-tropical, warm temperate and frost-free areas of cold temperate.
Soil: well-drained is best, but agave will tolerate anything except waterlogged situations.
Position: full sun to part shade.
Flowering: flower spikes between 2–8m tall, depending on the species.
Feeding: annual with a controlled-release fertiliser.
Watering: little once established.
Succulents are fantastic low-maintenance plants with serious textural style. There is an enormous range available, but the most popular is the agave.
Agave has a distinctive rosette form to its soft, sappy foliage, and this, combined with the bluey-green leaf colour, makes it instantly recognisable.
Agave is an excellent survivor, and unlike many other tough plants, it won't go weedy. It's not unusual to see this agave thriving in an old or neglected garden where every other plant is suffering. Its name comes from its tall flower spike, which can be as tall as 4m. It's covered in small yellowish flowers.
Flowering is very irregular. In fact, there is great debate as to when agave typically flowers, and what triggers flowering. It can take up to 10 years before flowering. Once it does flower, the rosette that the flower spike emerged from will die, and will become surrounded by new pup plants. That's why in older gardens agave is often seen growing in large, mounded clumps.
Agave is a hardy, flexible plant suited for many uses:
Feature plant positioned for architectural impact.
Perfect for low-maintenance, low water use and sustainable gardens.
Plant in hard-to-access rockeries or garden beds.
Great in planter boxes in harsh locations.
Use as specimen plants in pots.
Certain species of agave are harvested to produce biofuel, tequila or agave syrup, a natural sweetener.
Virtually self-maintaining, agave is ideal for planting in difficult to reach areas or low-maintenance gardens. A full-sun location is ideal for agave, but it will tolerate some shade. In very hot, dry regions, protection from intense sun is recommended.
Free-draining soil of virtually any type, including gravelly or sandy, is best. Avoid heavy clay or wet situations, as being overly wet is one thing that may kill agave.
Agave will thrive in virtually any aspect, but it must be frost-free.
This is one of those rare plants where in virtually any soil, you can just dig a hole and pop it in! There is no need to improve the soil unless it is extremely sandy or gravelly, in which case you can add a small amount of quality compost. If the soil is very hard or compacted you will need to break it up to allow easy root penetration.
In pots, use a specialised succulent and cacti blend.
Agave has very brittle leaves, so it's best planted away from areas where it may be easily damaged, such as along narrow pathways or in areas where kids play.
As with all succulents and cacti, additional watering isn't generally required. However, occasional watering, especially in hot and dry times, will keep your agave happier and healthier.
Technically, no fertilising is required, but you'll get better performance if you feed your agave annually with a quality controlled-release fertiliser.
As leaves die or if they are badly damaged (which can happen, as they are quite brittle), trim them off close to the trunk.
Agave requires little pruning beyond removing old or damaged leaves, and trimming back the dead shoot after flowering has finished.
Agaves are relatively pest- and disease-free.
