Polka dot begonia

Polka dot begonia

Begonia maculata
A cane begonia from the Atlantic rainforest of southeast Brazil, grown as a houseplant for its long, wing-shaped, olive to dark green leaves spotted with silver above and red beneath, carried on upright stems jointed like bamboo. NC State Extension lists it among the cane-type begonias at 2 to 3 feet tall, with drooping clusters of white to pink flowers with small yellow centres, and Wikipedia explains that the silver spots are air trapped in the skin of the leaf. Flora do Brasil records it as endemic to Brazil. Outside USDA zones 10 and warmer it lives indoors, in bright light out of direct sun, in humid air and in moist but well-drained soil, since begonias rot when overwatered. It is toxic to pets: the ASPCA lists begonias as toxic to dogs, cats and horses, and NC State Extension says the sap can irritate skin.

Two pure white Easter lily (Lilium longiflorum) flowers held horizontally, each a long narrow trumpet flaring into six waxy recurved lobes, with a green-white style and bright yellow anthers inside. Rain droplets stand on the petals; a third unopened trumpet points away behind, over dark foliage.
Lilium longiflorum
Easter lily
Easter lily reaches most people the way almost nothing else in this catalog does: as a forced gift plant in a foil-wrapped pot, in full white trumpet in March or April, months before its real season. Left to itself in a garden Lilium longiflorum flowers in July and August, and Missouri Botanical Garden files it under the plainer name trumpet lily. Everything about the pot version is engineered - bulbs lifted in autumn from a narrow strip of the California and Oregon coast, cooled, potted, held under a temperature schedule that lands the buds on a date that moves by up to five weeks a year, and kept short with growth retardants. That is why the plant you were given is 16 to 20 inches tall and the same plant in the ground is 2 to 3 feet. The single most important sentence in this record is not horticultural. This is the species behind the veterinary literature on feline lily poisoning: every part of it, including the pollen and the water in the vase, causes acute kidney injury in cats, less than one leaf can be enough, and untreated cases die in 36 to 72 hours. It is also the lily that enters houses in quantity, which is the whole problem. If there is a cat in the house, this plant does not come in the door. Beyond that, be clear about what it is not. It is not a hardy garden bulb in the way the regal lily in this wave is - Missouri Botanical Garden rates it zone 4 to 8, which is the most generous number in circulation for a subtropical island endemic, and much US extension guidance says 5 to 8. It is not a widespread wild species either: Kew's native range is the Ryukyu Islands, Taiwan, southern Japan and the Philippines, and nothing else. A globally traded flower with a natural range you could drive across in a day.

African lily (Agapanthus praecox) - rounded umbels of trumpet-shaped blue flowers on tall bare stalks, strap-shaped arching basal leaves forming a clump, multiple flowering stems in a garden bed showing the perennial's clump-forming habit.
Agapanthus praecox
African lily
A bold, clump-forming evergreen perennial from South Africa, grown for big rounded umbels of trumpet-shaped blue (or white) flowers held on tall bare stalks above arching, strap-shaped leaves in mid-to-late summer. It is widely sold as "lily of the Nile," but that is a misnomer - the plant is South African (the Cape provinces and KwaZulu-Natal), not from the Nile. Spectacular and easy in warm climates, this evergreen Agapanthus is frost-tender, so in cold-winter areas it is grown in a container and overwintered under cover. The RHS has given several Agapanthus praecox forms its Award of Garden Merit and rates this evergreen species half-hardy (H3 - needs winter protection).

African mask (Alocasia × mortfontanensis) seen from above: a potted clump of arrow-shaped, very dark green leaves with thick, pale lime-white veins and deeply wavy, scalloped edges, among clay pots on a white plant stand, with a white, pink-flecked caladium leaf at the right edge.
Alocasia × mortfontanensis
African mask
A garden-bred aroid, a cross between Alocasia longiloba and the kris plant (Alocasia sanderiana) raised by the French horticulturist Chantrier at Mortefontaine and named Alocasia × mortfontanensis in 1891. It is sold mostly as Alocasia amazonica or Alocasia × amazonica: NC State Extension lists that as its former name, and Singapore's National Parks Board says the amazonica name was never validly published and seems to come from Amazon Nursery, a 1950s Florida nursery, not from the Amazon. It grows from a rhizome into a clump of arrow-shaped, very dark green leaves with bold silver to lime-white veins, wavy edges and purple undersides, 1 to 4 feet tall according to NC State. Outside USDA zones 10a to 12b it is a houseplant for bright, indirect light, kept above 60°F. Every part is poisonous: the ASPCA lists Alocasia as toxic to dogs, cats and horses, and NC State says the sap can also irritate skin and eyes.

An angel wing begonia (Begonia coccinea) in Athens: a small, dangling cluster of scarlet-red, heart-shaped winged flowers on red stalks hangs among long, glossy, dark green, wing-shaped leaves faintly dotted with white, with more red flower clusters blurred in the foreground against a pale, out-of-focus background.
Begonia coccinea
Angel wing begonia
A begonia from the Atlantic Forest of Rio de Janeiro and Espírito Santo in Brazil, also called scarlet begonia, whose name is attached to the angel wing begonias grown as houseplants: cane begonias with upright, jointed stems, wing-shaped leaves and drooping clusters of red, coral or pink flowers. Buy it knowing what the label means. Flora do Brasil warns that the name is often attached to a cultivar of Begonia maculata, while the wild species is a small shrubby plant that grows on trees more than 66 feet tall, and most plants sold as angel wing begonias are cane hybrids. Outside USDA zones 10 and warmer it lives indoors, in bright light out of direct sun, in humid air and in moist but well-drained soil. It is toxic to pets: the ASPCA lists begonias as toxic to dogs, cats and horses.

Hylotelephium 'Herbstfreude'
Autumn-joy stonecrop
A clump-forming herbaceous perennial grown for its showy late-season flower heads: masses of tiny star-like flowers borne in flattened cymes 3 to 6 inches across that emerge rosy pink, deepen to rose-red, and fade to coppery-rust as they die. Gray-green, fleshy, succulent-like leaves form upright clumps to about 24 inches. Easily grown in dry-to-medium, well-drained soil in full sun, it is drought tolerant and attracts butterflies, and its foliage and dead inflorescences persist into winter for added interest.

Bird of paradise (Strelitzia reginae) - orange sepals + blue petal tongue, horizontal boat-shaped bract, crane-head flower silhouette.
Strelitzia reginae
Bird of paradise
A clumping, multi-stemmed evergreen perennial from South Africa, grown for its unmistakable crane-head flowers - a horizontal green-and-pink spathe from which bright orange sepals and vivid blue petals emerge like the crest of an exotic bird. Bold, paddle-shaped blue-green leaves on long stalks form a 3-4 foot fountain of foliage. Winter hardy only in USDA zones 10-12 (frost-free subtropics); everywhere colder it is grown as a houseplant or summered-out container plant. It blooms reliably only from a well-established, somewhat crowded clump, so patience is the key to flowers.

A spherical scarlet flower head of Scadoxus multiflorus (blood lily), composed of many slender red flowers with protruding stamens, atop an upright leafless stem.
Scadoxus multiflorus
Blood lily
Scadoxus multiflorus, the blood lily (also fireball lily, ball lily, powderpuff lily), is a summer-growing bulbous geophyte in the Amaryllidaceae, native across tropical and southern Africa to the southwestern Arabian Peninsula. Each bulb sends up a leafless stem topped by a dramatic globe-shaped umbel of scarlet flowers with protruding stamens, often before or alongside the foliage. It is a focal-point container and bedding bulb prized for its bold flower head, but it is decidedly tender - RHS rates it H1B (minimum 50 to 59°F), so outside roughly USDA zones 9b–11 it must be grown under glass or as a houseplant and dried off / overwintered frost-free. CRITICAL CAUTION: every part is toxic - Scadoxus contains poisonous alkaloids and has been used as a component of arrow and fishing poisons; the bulbs are ornamental, not edible, and the plant is harmful to people, pets, and grazing animals if ingested. Handle with gloves and keep away from children and animals.
