Prized for the shape and pretty color of its foliage, Senecio mandraliscae (Blue Chalksticks) is a spreading succulent from South Africa with 3-4 in. long (7-10 cm), silvery blue, finger-like fleshy leaves and small white flowers in summer. Quickly forming a dense blue mat with its upward curving leaves, this low-growing succulent is highly versatile and ideal as a border plant or as a groundcover. Great for creating a low, blue edging too.

Senecio vitalis (Narrow-Leaf Chalksticks) is a spreading evergreen succulent of great ornamental appeal with its cylindrical gray-green foliage. Its slender, slightly upcurved leaves, 3-5 in. long (7-12 cm), are glaucous-gray, finger-like. They encircle the trailing stems and form handsome tufts at the stem tips. Erect at first, the stems become procumbent and often root at the nodes as they touch the ground. Small creamy-white flowers held in corymbs rise just above the foliage in late spring to early summer. Quickly forming a dense mat with its upward curving leaves, Senecio vitalis makes a great finely textured, medium height groundcover and provides extraordinary form and color contrast in the landscape.

Native to Australia, Anigozanthos flavidus (Kangaroo Paw) is an evergreen rhizomatous perennial with interesting flower shapes atop fans of slender, strap-shaped leaves. Borne on long, leafless flowering stalks, the remarkable flowers, are usually yellow-green, but can be orange, red, pink or green. Clustered at the ends of the stalks, they are tubular, covered with velvety hairs and have pointed lobes, which are curved at their tips, giving them the appearance of kangaroo paws, hence the common name. A striking and easily-grown perennial for frost-free or nearly frost-free climates, Anigozanthos flavidus enjoys a natural resistance to disease and insect attack.

Incredibly beautiful and majestic, Agave americana (Century Plant) is a very large, evergreen perennial forming handsome rosettes of thick, spiny-edged, blue-green leaves, up to 6 ft. long (180 cm). The older leaves often gracefully arch down, suggesting motion, which makes the garden even more intriguing. Mature plants (at least 10 years old) are topped with a magnificent flower stalk that can reach 15 ft. (4m50), and bears large greenish-yellow flowers. This desert plant makes a dramatic focal point or accent and can be used in decorative pots away from foot traffic.

Slow-growing, award-winning Dracaena draco (Dragon Tree) is an evergreen tree with attractive hefty limbs and stiff but flexible leaves. Sparsely branched, the thick, swollen, cylindrical trunk, branches into stout, upright arms with terminal rosettes of sword-shaped, blue-green leaves to 2 ft. in length (60 cm). Initially smooth and gray, the bark becomes scaly with horizontal, red stripes, a reminder that this tree bleeds crimson sap when the bark is cut or bruised. Likened to the blood of dragons, (Dracaena means dragon in ancient Greek), this sap is used as a varnish for violins and other fine wood. In early summer appear panicles of greenish-white flowers on mature plants. They are followed by orange berries.

Noted for its incredibly showy bracts, Euphorbia milii, commonly called Crown of Thorns, is a sprawling evergreen shrub with succulent branches lined with long, sharp, black thorns and sparsely leafed. The foliage of leathery, obovate, bright green leaves is produced only on new stem growth. The eye-catching blooms consist of tiny, inconspicuous, yellow flowers held in clusters subtended by very showy and long-lasting red bracts, resembling petals. This plant flowers over an extremely long season, throughout the year in tropical and sub-tropical locations, from late winter well into fall if grown indoors.
