Jubaea chilensis







Jubaea chilensis
Chilean Wine Palm
This slow growing palm, the only extant species of this genus named after Juba II, a Berber king and botanist, can reach up to 50-60' in height and 25' in width. It needs mild winters, but will tolerate frosts down to about −15 °C (5.0 °F) as well as relatively cool summers, making it one of the hardiest of pinnate-leaved palms; this is because it grows up to 1,400 metres (4,600 ft) above sea level in its natural habitat. In the wild, the tree lives almost exclusively on the steep slopes of ravines. The base of the trunk can reach 3' in width tapering toward the top. The trunk is smooth and scarred with the leaf patterning. The Chilean Wine Palm prefers full sun with little to no water.
The common name refers to the past use of the sap from the trunk of this palm to produce a fermented beverage. The sap is also boiled down into a syrup and sold locally as mile de palma. The tree also produces small round fruits that are about 2-3 cm (1 inch) in diameter. The fruit has a very hard outer shell and has a whitish meat on the inside.

Euphorbia cotinifolia






Euphorbia cotinifolia

Caribbean Copper Tree

This is a deciduous tropical shrub that will grow to 15 feet tall and can be trained as a small tree. The flexible purplish stems hold coppery-purple thin-fleshy broad leaves and a shiny smooth bark. Loose flower clusters have small white to pale yellow bracts in the spring. As this plant is not frost tolerant, it should only be planted outdoors in areas that are protected from frost. It does its best in sun with moderate water and good drainage.

Chondropetalum elephantinum




Chondropetalum elephantinum and Chondropetalum tectorum

Cape Rush (or Roof Reed)

This South African plant forms dense tufted clumps from which arise 4 feet tall dark green unbranched stems. The dark brown sheaths at the joints drop off in summer leaving a dark band at each node. Late in the season the stems arch gracefully from the weight of clusters of small brown flowers at the tips. Male and female plants have remarkably similar flowers but the female flowers are held tighter and clustered toward the tip of the stems. Plant in full to part sun. It is drought tolerant, but appreciates supplemental water in spring. It is hardy to about 20-25 degrees F and tolerates a wide soil pH range. In its natural habitat Chondropetalum elephantinum grows close to the coast from Clanwilliam to Grahamstown, often preferring marshy habitat. It can be successfully planted in seaside gardens, used in relatively dry landscapes or as a plant in the shallows of a water garden.

The large population of Chondropetalum that grows along the west coast near Cape Town, South Africa is taxonomically different from another small population of plants found further from Cape Town. The name Chondropetalum elephantinum has been assigned to the population that is closer to Cape Town as it is typically a larger plant, growing to 2 meters tall. The name Chondropetalum tectorum was retained for the other population that only grows to 1 meter tall.

Populus tremuloides

Populus tremuloides

Quaking Aspen

Populus tremuloides is a deciduous tree native to cooler areas of North America. The species is referred to Quaking Aspen, Trembling Aspen, and Quakies, names deriving from its leaves which flutter in the breeze. The tree-like plant has tall trunks, up to 25 metres, with smooth pale bark, scarred with black. The glossy green leaves, dull beneath, become golden to yellow, rarely red, in Autumn. The species rarely flowers, often propagating through its roots to form large groves.

It propagates itself primarily through root sprouts, and extensive clonal colonies are common. Each colony is its own clone, and all trees in the clone have identical characteristics and share a single root structure. A clone may turn color earlier or later in the fall than its neighbouring aspen clones. Fall colors are usually bright tones of yellow; in some areas, red blushes may be occasionally seen. As all trees in a given clonal colony are considered part of the same organism, one clonal colony is considered the heaviest and oldest living organism at six million kilograms and approximately 80,000 years old.

Chionochloa rubra





Chionochloa rubra
Red Tussock

This grass, endemic to New Zealand, is often found in great drifts in lowland and low-alpine areas in the volcanic mountains. Common on the mineral belts of the South Island and on poorly drained peaty valley floors or rolling slopes mostly below the tree line. Not especially showy in flower, but attractive for the strong red-copper foliage. It can grow to be 3-4' tall.

Fenestraria rhopalophylla

Fenestraria rhopalophylla

Baby toes or Window plant

 

 

Fenestraria is a monotypic genus of succulent plants in the family Aizoaceae. The species is also called babies toes or window plant. On each leaf there is transparent window-like area at the top, it is for these window-like structures that the genus is named (Latin: fenestra). In the wild, the plant grows mostly buried by sand. The transparent tips are often above the sand and allow light into the leaves for photosynthesis. F. rhopalophylla is native to Namibia and Namaqualand in southern Africa. The plants are generally found growing in sandy or calciferous soils under low < 100 mm rainfall.

Ratibida columnifera




Ratibida columnifera
Mexican Hat, Yellow Coneflower

These upright perennials (1-3') bloom in the summer at elevations between 5,000 to 8,5000 feet on plains and in openings in pine forests. The Yellow Coneflower has a purplish central cone and reflexed yellow petals whitele the Mexican Hat has drooping brick-red ray petalss and red disks. They prefer full sun and require little maintenance. They were often used bu Native Americans as a snakebite remedy and to reduce fevers.
