Bottle palm
Hyophorbe lagenicaulis
The bottle palm (Hyophorbe lagenicaulis) is a solitary palm from the Arecaceae family, endemic to Round Island in the Mascarene Islands (Mauritius). It is famous for its smooth, grayish trunk, which is swollen in a bottle shape at the base and tapers toward the crown, supporting a small canopy of 4 to 8 deep green pinnate leaves (young plants often show reddish or orange tones). A slow-growing species, fewer than 10 adult specimens remain in the wild, making it critically endangered, although its ornamental cultivation is widespread in tropical and subtropical climates worldwide.
Prayer Plant
Maranta leuconeura
Maranta leuconeura is a tropical plant native to Brazilian rainforests, prized for its decorative leaves with unique colorful vein patterns. Its common name "Prayer Plant" comes from the nyctinastic movement of its leaves, which fold upward at night like hands in prayer and open during the day to absorb light.

London plane
Platanus × hispanica
The London plane (Platanus × hispanica) is a large deciduous hybrid tree, a cross between the Oriental plane (P. orientalis) and the American sycamore (P. occidentalis). It is instantly recognizable by its distinctive bark that peels away in patches to reveal cream, olive, and grey mottled patterns beneath, and by its large maple-like leaves. One of the most widely planted urban trees in the world, it is prized for its exceptional tolerance of air pollution, compacted soils, and drought once established.
American Sycamore
Platanus occidentalis
The American sycamore is one of the largest native hardwood trees in eastern North America, commonly reaching 75-100 ft (23-30 m) tall with a broad, spreading crown. It is best known for its distinctive exfoliating bark, which sheds in irregular gray-brown plates to reveal smooth, creamy-white inner bark. Native to riverbanks, floodplains and bottomlands, it tolerates wet soils as well as periods of drought once established. Small monoecious flowers appear in early spring (green male clusters, burgundy-red female clusters), followed by distinctive ball-shaped seed heads that persist through winter.
Staghorn Fern
Platycerium bifurcatum
Platycerium bifurcatum is a striking epiphytic fern native to the rainforests of Australia, Java, and New Guinea. Known for its unique antler-shaped fronds, this plant naturally grows on trees and rocks, absorbing nutrients and moisture from the air. It produces two types of fronds: sterile shield fronds that anchor the plant and fertile fronds that resemble deer antlers. With proper care, staghorn ferns can live for over 50 years and become impressive living sculptures.
Geranium Aralia

Henry's lime
Tilia henryana
Henry's lime (Tilia henryana) is a deciduous tree native to the mountain forests of central China (Anhui, Hubei, Hunan, Shaanxi, Zhejiang...), introduced to the West by Ernest Wilson in 1901. More compact than the common lime, it reaches 30 to 50 ft in height in cultivation (up to 80 ft in its native habitat), with a rounded, spreading habit and pale gray bark that fissures with age. Its heart-shaped leaves, coppery when budding then glossy green, are distinguished by a ciliate margin of long silky bristles reminiscent of a carnivorous plant's eyelashes, before turning golden yellow in autumn. The late flowering (late August-September) produces abundant clusters of highly fragrant, nectar-rich creamy white flowers, among the last of the Tilia genus to open.
Blushing Bride
Tillandsia brachycaulos
Tillandsia brachycaulos is a small epiphytic air plant native to Mexico and Central America, prized for its dense rosette of narrow, silvery-green leaves that dramatically flush deep red to scarlet in the weeks before flowering, the trait behind its common name, "Blushing Bride." It thrives without soil, drawing water and nutrients through specialized leaf scales called trichomes, and produces violet-to-purple tubular flowers rising from red or orange bracts.
Pink Quill
Tillandsia cyanea
Tillandsia cyanea, known as the Pink Quill, is an epiphytic air plant native to Ecuador prized for its long-lasting bright pink flattened bract that rises from a rosette of narrow, arching green leaves. Unlike soil-grown houseplants, it has no true roots for absorbing nutrients -- instead it draws water and nutrients through specialized trichomes on its leaves. Small tubular violet-blue flowers emerge one at a time from the pink bract, which itself can stay colorful for two to three months.
Blue-flowered Torch
Tillandsia lindenii
Tillandsia lindenii, commonly called the Blue-flowered Torch, is an eye-catching epiphytic bromeliad native to the cloud forests of Ecuador and Peru. It forms a compact rosette of arching, dark green, strap-like leaves from which rises a flattened, sword-shaped bract in shades of green, pink, or rose. From this striking bract emerge a succession of large, deep violet-blue flowers with white throats, each lasting only a few days while the colorful bract itself persists for months. Grown as a houseplant, it thrives mounted on bark or lightly potted in a well-aerated, soil-free medium, needing no traditional soil since it absorbs water and nutrients through specialized leaf scales called trichomes.
American elm
Ulmus americana
The American elm (Ulmus americana) is a fast-growing, deciduous tree from the elm family (Ulmaceae), originally native to eastern North America. The tree is known for its characteristic vase-shaped crown and can reach heights of up to 24 meters in the wild with a correspondingly wide canopy. From the mid-20th century, Dutch elm disease decimated large portions of the wild population in North America, but disease-resistant cultivars have since been developed. The species produces small, inconspicuous greenish-red flowers in early spring before the leaves emerge, and features coarse, dark green foliage that turns golden in the fall.
Pink quill
Wallisia cyanea
Wallisia cyanea (formerly Tillandsia cyanea), known as the pink quill, is an epiphytic bromeliad native to the tropical forests of Ecuador. It forms a dense rosette of narrow, grass-like leaves from which a flattened, vibrant pink spike resembling a quill emerges. From this spike, short-lived violet-blue flowers appear sequentially over several months. It is a slow-growing plant that does not require soil, primarily cultivated for its spectacular, long-lasting colorful inflorescence.
