(Horombe Clubfoot, Yellow Bell Pachypodium)
This succulent's plump, bottle-shaped base with numerous fat arms covered in spines seems to be taken from images in a Dr. Seuss book. The yellow bell pachypodium also bears yellow flowers on long stems during the warm months of the year. This semiarid succulent shrub or dwarf tree is native to the Horombe Plateau in south-central Madagascar. The trunk and branches are covered with short paired spines. A caudex also is present: a swollen trunk-root transitional area that stores water. Unless in flower,...
(Madagascar-palm, Naked-blooming Clubfoot, Pachypodium, Single-spined Clubfoot)
Another small succulent tree that's the spitting image of Pachypodium lamerei, the single-spined clubfoot, also called Madagascar-palm, blooms when leafless. The sparse, singular spines on the gray trunk are subdued, but it's the white flowers with twisting petals that are the plant's ornamental pride. Native to southern Madagascar, the misleadingly named Madagascar-palm is closely related to oleanders (Nerium spp.) and desert roses (Adenium spp.) than true palms.. This...

(Jicama, Mexican-potato, Mexican-turnip, Yam-bean)
Originating in Mexico, jicama today is a root vegetable often used in culinary dishes across Southeast Asia and Central America. "Jicama" is an ambiguous Spanish term for any edible root, so some may prefer to call this the Mexican-potato or Mexican-turnip. A frost-tender, evergreen vine, it's grown for its edible tuber root. The root's exterior is yellow-tan with a crisp, creamy white flesh. The flavor is sweet and starchy, like a cross between an apple and waterchestnut. Jicama is often eaten raw,...

(Lollipop Plant, Yellow Candles, Yellow Shrimp Plant)
Yellow candles is a tender tropical shrub with intriguing yellow and white flowers. This plant, native from Costa Rica to Peru, has pointy oval leaves that are pleasing green. From the tips of branches, a yellow "candle" or bract appears, from which white tubular flowers emerge. These flowers attract hummingbirds.
Place yellow candles in a moist, well draining soil that is fertile and not alkaline. Although it can grow in full sun, its leaves look much nicer if placed in a partially shaded garden...

Tahitian screwpine becomes a tall, architecturally attractive "tree" with evergreen, sword-like leaves and fruits that are large and golden yellow. This tender, tropical evergreen is slow growing with origins in the South Pacific, from Hawaii and Tahiti westward to Indonesia and Australia. They are not true trees, but are related to palms and bamboos, and ever so slowly will attain a magnificent, open-branched, pyramid shape. They have numerous fleshy, fibrous prop roots at their bases, used to anchor...

Common screwpine becomes a tall, architecturally attractive "tree" with evergreen, sword-like leaves and fruits that are large and golden yellow. This tender, tropical evergreen is slow growing and considered a native of the Old World Tropics, now believed to have originated in Madagascar. They are not true trees, but are related to palms and bamboos, and ever so slowly will attain a magnificent, open-branched, pyramid shape. They have numerous fleshy, fibrous prop roots at their bases, used to anchor...

A large ornamental grass, tussock paspalum forms clumps of light bluish green foliage and can send up tall wispy flower spikes twice a year (or more) in frost-free regions. This warm-season perennial bunchgrass forms thick clumps, and in fertile and moist soils will aggressively spread via underground stems called rhizomes and by seed. Thus, it can be invasive, and is considered quite noxious in Australia. Tussock paspalum is native to Uruguay, Paruguay, Brazil and Argentina.
This tall plant...

Red passion flower is a perennial vine native to northwestern South America. It is evergreen in frost free locations and deciduous in colder locations. Dark green, simple, oval to oblong leaves have double-toothed margins and are arranged alternately on the stem. The vines climb by tendrils produced in the leaf axils (joint between the leaves and stems) on round, angled branches covered with red hairs. Beautiful flowers appear summer through fall. The complex, fragrant, bowl-shaped flowers are composed...
This rare and exotic coral pink passionflower is a tropical climber that thrives in frost free regions. Like all of its kind, the species is native to South America, namely the jungles of Ecuador where it is now quite scarce in the wild. This plant is often sold as Coral Seas in the nursery trade. They are generally evergreen perennials, bearing lobed leaves and are arranged alternately on the stem. The vines can become very large and climb by tendrils produced in the leaf axils (joint between the...
This vivid coral passionflower is a spectacular tropical climber that is proving more frost tolerant than most other similarly colored vines. Like all of its kind, this species is native to South America, where it is an evergreen perennial, bearing dark-green, lobed leaves arranged alternately on the stems. It can become very large and climb by tendrils produced in the leaf axils (joint between the leaves and stems).
The complex, intensely coral-red flowers of this species are produced singly...
