Begonia luxurians

Palm leaf begonia

Brazil

This cane-type begonia grows up to 8 feet tall. Clusters of lightly fragrant white flowers appear from spring through fall.

Grow in partial sun to shade in a protected spot; it will recover from light frosts. The palm leaf begonia requires even moisture to replicate its tropical forest home.

Distinctive leaves are the main feature of this begonia. They are palmately divided and reflexed, resembling miniature palms.

Cleistocactus smaragdiflorus

Argentina, Bolivia, Paraguay

This cactus grows as a multi-stemmed shrub. The plant is densely branching at the base producing many stems that are 2 to 3 inches in diameter with 12 to 16 ribs.

Fast-draining soil and full sun are required. Water regularly through the hot summer months. Protect from frost.

The numerous narrow tubular flowers appear nearly year round. They are bright pinkish red with a yellowish green tip.

Magnolia X soulangiana

Magnolia bush

Cultivated origin

This magnolia hybrid may grow as a multi-trunked or single-stemmed bush. It usually grows 10 to 15 feet in height. Flowers appear in early spring before the glossy green leaves.  

While perfectly happy in our Mediterranean climate, this magnolia will also thrive in temperate climates. Regular water and rich soil produce good results.

The showy flowers are cup shaped, reddish purple on the outside shading to nearly white on the inside.

Several specimens grow in the Japanese garden.

Agave attenuata

Mexico

This agave is among only a few that do not have sharp spines along the edges or at the tip of its leaves. The leaves are soft and light green forming rosettes up to four feet across. It often branches near the base of a stalk to form larger clumps. The inflorescences arch up and then toward the ground and individual flowers bloom in succession from the base to the tip over a long period. A blue-leaved selection (Agave attenuata ‘Boutin Blue’) has erect inflorescences. Both types often produce many little plantlets along the spent flower stalk that will root on the ground if given the chance.

Agaves are by and large desert plants. Their succulent leaves store water through dry periods making them extremely drought tolerant. Give them good drainage and a sunny or only slightly shaded site.

The bold rosettes of leaves provide a good accent plant in the drought tolerant garden. They even blend well with more tropical looking plants.

Kalanchoe fedtschenkoi

Madagascar

This succulent-leaved plant forms sturdy stems that are topped with clusters of nodding, bell-shaped flowers. They are an interesting shade of dusky rose that contrasts nicely with the bluish gray of the leaves. In winter, when the flowers are emerging, the leaves may also take on a reddish tinge because of the cold.

This kalanchoe is readily propagated from stem cuttings or by simply sticking the base of a leaf in well-drained soil. Grow in full sun to moderate shade. It is very drought tolerant and requires no supplemental water once established.

The flattened leaves are scalloped along the margins and are often held at an optimum angle toward the sun, making the whole plant look two dimensional.

Growing at the base of the tall Kalanchoe beharensis plants near the bromeliads and succulents.

Aechmea fasciata

Native to Brazil.

The vase-like rosette of leaves of this bromeliad is gray-green with a row of black spines along the margins. Plants produce bright pink inflorescences after several years. While the original plant will die after flowering, it will produce several offsets that may be removed and replanted. It is usually epiphytic in its native range, but adapts well to containers or raised beds outdoors.

Grow Aechmea fasciata in bright shade either in a pot or in the ground with lots of organic material incorporated into the soil mix. Soil may be allowed to dry out between waterings, but maintain the central cup – made by the tightly overlapping leaves – full of water at all times. Fertilize every month or two with half-strength liquid fertilizer in the central cup.

This bromeliad is probably one of the best known and easiest to grow. It is regularly available in nurseries, home improvement centers and supermarkets.

There are a number of plants in both the upper bromeliad and lower bromeliad gardens.

Euphorbia lambii

Canary Islands

A fast-growing shrub reaching to 7 feet tall and almost as wide. It initially has a single trunk which branches with age. Spreads by self-seeding.

Grows best in full sun to partial shade, and while it is drought-tolerant, it requires some water during growth and flowering seasons. It tolerates different types of soil and can take light frost.

E. lambii bears rosettes of slender blueish-green leaves arranged on the ends of the branches. It produces large clusters of showy chartreuse flowers in early spring.

A planting of Euphorbia lambii is growing along with many other species of Euphorbia along the Main Drive.

Blechnum occidentale

Hammock Fern

West Indies and Mexico through Central and South America

This clumping fern spreads rapidly by underground rhizomes. The fronds are 2-3 inches across and reach up to two feet tall.

Hammock Fern grows best in partial sun to full shade, in moist soil. It makes an excellent ground cover.

The new fronds emerge a striking pink color which darkens to bronze then green at maturity.

Blechnum occidentale is planted throughout the Fern Garden.

Aloe arborescens

Candelabra Aloe

South Africa

A clumping perennial with groups of stems spreading 10 feet tall and 6 feet wide.

Shade to partial sun, moderate water. It can adapt to a wide variety of soil types.

A. arborescens is called “Candelabra Aloe” for its spikes of deep red flowers which bloom profusely through the winter months.

There are many specimens of A. arborescens throughout the Aloe Garden. There is also a planting along the Main Drive by the Sycamore Canyon gate.
