Agave ‘Blue Flame’ is named for its glaucous, blue-hued leaves common to many agaves, but also for its shape. Its gently curving leaves resemble the flames of a gaslight. Leaves are bluest when young, becoming gradually greener as they age. The leaf margins are finely serrated, with a reddish-brown stripe along the edge and a terminal spine. Leaf margins appear to glow when backlit by sunlight. Mature plants are large rosettes between three and five feet tall and wide. Richer soils will produce taller bloom stalks.
Light: Full to partial sun along the coast; shade from afternoon sun inland
Hardiness: 20 degrees Fahrenheit
Agave ‘Blue Flame’ is a fast-growing agave. After flowering, the plant will produce pups that will grow in an ever-expanding clump. The pups can also be removed and re-planted elsewhere. Allow adequate room for the plant to mature when re-setting. Can benefit from supplemental water during dry, hot summers.
Agave ‘Blue Glow’, smaller-leafed succulents such as sedum, senecio, low-water ornamental grasses
A striking specimen plant for the landscape, Agava americana 'Mediopicta' has long, stiff, variegated green and cream striped leaves with a wicked terminal spine and serrated edges. Grows to between 3-5 feet tall and wide, so leave space for it to grow and/or plan to remove companion plants as the Agave needs more room. Sap can cause allergic reactions in people.
Light: Full sun
Hardiness: 15 degrees Fahrenheit
Highly drought-tolerant. Plant in full sun in well-drained soil. Take care when working around the plant as "pokes" from the plant can cause allergic reactions in some people.
Senecio, Sticks-on-fire, and ornamental grasses are all excellent companion plants. Because of the leaf variegation, stick to companions with solid-colored foliage if you want the Agave to stand out.
Agave attenuata is sometimes called the "foxtail agave" because its flower spike looks like a long fox tail. These agaves have yellow-green soft, spineless leaves arranged in 12-24 inch rosettes on top of bare stems. Will form masses in the landscape up to 4-5 feet across and 4-5 feet tall.
Light: Full coastal sun to partial shade, partial shade to shade inland
Hardiness: 28-30 degrees Fahrenheit (very cold-sensitive)
May need water during extreme drought. Can cut off, callus, and re-set in the landscape. Pay careful attention to weather forecast during the winter and cover if frost is predicted.
Looks best with fine-textured plants including senecios and ornamental grasses. Smaller, tighter rosette-formed plants also contrast nicely with Agave attenuata, including, particularly, echeverias.
Agave attenuata 'Kara's Stripes' has soft greenish-yellow leaves with green leaf margins. They form upward-facing rosettes. There is some color variation between plants. Grows to an eventual height of three feet. Somewhat slower growing than other attenuatas.
Light: Coastal full sun to shade, inland partial shade to shade.
Hardiness: 30 degrees (very cold-sensitive)
Cover when frost is predicted. Water during times of extreme drought. Salt-tolerant
Ornamental grasses, aeonium, echeveria.
Agave gemniflora has soft, but strongly upright narrow leaves with shredding margins. (The leaves have little white curlicues along the edges.) Terminal spines are sharp. Looks attractive when mass-planted.
Light: Coastal-full sun, inland-partial shade
Hardiness: 25 degrees fahrenheit
Water occasionally during the heat of summer. This plant does not usually produce offsets after flowering.
Narrow leaves contrast well with wide-leafed agaves, echeverias, and aeonium.
Agave titanota has broad pale light blue to light green leaves with inward curving spines along the edges and a sharp terminal spine. Native to limestone cliffs and grows best in extrememly well-drained soil. Grows 2-4 feet tall and wide.
Light: Full sun
Hardiness: 25 degrees Fahrenheit
Cannot tolerate wet feet at all. Leave alone and take care when working around.
Wide, light colored leaves of this plant contrast well with narrow, dark-leafed succulents.
Agave weberi is a large specimen agave with a strongly upright growth habit. On some plants leaves curve back toward the ground halfway down--variation occurs. Grows to be 4-6 feet tall and 6-8 feet wide. Fleshy leaves have small marginal spines. Not as "fierce" as other large agave types.
Light: Full sun to partial shade
Hardiness: 10-15 degrees Fahrenheit.
Drought-tolerant and easy-care.
Plant with ornamental grasses and finely-textured succulents.
