    Overview and Description:

    At first glance, you probably wouldn’t called agave plants rosettes. So many of the common ones are spiny
    , with leaves that jut out in often dangerous spikes. There is actually a lot of variety in the agave genus. There are the large, stiff specimens that can grow to 20 feet in diameter. There are also small dish-sized agaves and agave plants with soft leaves and no spines. Most have leaves that end in a sharp point.
    • Leaves: Agaves are all stemless, or nearly...MORE so, with strappy, succulent leaves that end in sharp points. Foliage tends toward a blue-green in hardier varieties and a gray-green in warm climate varieties. There are also some that are variegated with gold or white markings.
    • Flowers: When the plant matures, a tall, flower-stalk grows out of the plant’s center. The flowers are bell-shaped and long lasting, in shades of white, yellow and green. For most agave species, once the flowers produce the berry seed pods, the plant dies.

    Botanical Name:


    Common Name(s):

    Sometimes referred to as the Century Plant, although that name is specific to
    Agave americana


    Most are not frost hardy, but there are agaves, like
    Agave parryi
    , that are hardy to
    5, but most are only hardy in Zones 8 or 9 and up.

    Light Exposure:

    to partial shade

    Mature Size:

    Varies from a few inches to 20+ feet in diameter.

    Bloom Period:

    Agaves bloom once, at maturity. That can be anywhere from 5 to 40 years. They tend to bloom earlier in cultivation than they would in the wild. Most plants die after flowering.

    Design Tips:

    One large agave is all that is needed to make a sculptural focal point. Just make sure there is lenty of room to walk around it, so no one gets stabbed. They can also make nice border grouping, either by planting several of the same species or a tapestry of different varieties. They are textural and sculptural and make a vivid contract with other plants. Pairing them with
    softens their hard edges. In warm climates, agave are popular around pools and patios. Their leaves don’t brown and drop frequently and they stay attractive all year. I’d suggest using a spineless variety, like the Foxtail Agave (
    Agave attenuata
    ). Smaller agave plants are excellent for containers, indoor or out.

    Suggested Varieties:

    • Agave attenuata - A popular spineless variety also known as the Foxtail or Dragon-Tree Agave. Grows about 4 - 5 feet tall and a bit wider.
    • Agave parviflora - Leaves have white, graphic markings and curlng filaments that give it a hairy look. It only gets about 6 in. Tall and blooms in 6 - 8 years with green flowers on a 4 - 6 ft. spike.
    • Agave tequilana azul - Weber's Blue Agave is used to make a tequila, in Jalisco, Mexico, but it is also a very attractive garden plant, reaching upwards of 6 ft. tall and flowering in 6 - 8 years with a 15 ft. spike of yellow blooms.
    • Agave victoria-reginae - As the plant matures, the broad leaves cup inward, forming a dome. Reaches a height of about 12 in.. Cream flowers appear in 20 - 30 years

    Growing and Caring for Agave

    Growing Tips:

    Agaves thrive on neglect. They grow quickly and remain attractive all year.

    Propagation: Since it can take years for agaves to produce seed, most are propagated by off sets or tissue culture.

    Soil: Agave will tolerate any well-draining soil, but their preference is rocky or sandy soil. They are not particular about soil pH.

    Water: When you are first establishing a plant outdoors, water it every 4 - 5 days for the first month. Then once a week, gradually spacing watering to every other...MORE week, depending on the weather.

    Feeding: Don’t. Agaves seem to take care of themselves. Feeding encourages flowering, which you don’t want to happen too soon.

    Growing in Containers: Container Grown Agaves: As with many succulent plants, agaves are shallow rooted. You can grow them in any size container, because they don’t need much soil. Use a well-draining soil. You can mix your own with something like 2 - 3 parts potting mix and 1 part gravel.

    Repot container grown plants every couple of years, with new soil. Agaves can produce sucker roots. If the pot is overly crowed with roots, go ahead an cut it back to size. Give the plant a week or so to readjust, before you water it again.

    Water about once a week in th summer and monthly in the winter, when the surface of the soil is dry. Plants in containers or in dry conditions may need more frequent water, but agaves are very forgiving.

    Pests and Problems:

    Agaves have very few problems. The agave snout weevil will burrow into the plant’s center to lay its eggs, causing the plant to collapse. Unfortunately you probably won’t notice this until it’s too late. Remove the plant and check for any remaining grubs.
