Question: Which is a perennial plant, Chelidonium or Duranta?

Context paragraphs:
Hemitomes: Hemitomes is a monotypic genus of plants containing the single species Hemitomes congestum, which is known as gnome plant and cone plant.  This rare and unusual plant is native to the west coast of North America from British Columbia to California, where it grows in dense, dark forests such as the redwood forests of the region.  This is small, fleshy, stemless perennial plant forming lumps in the leaf litter.  It is white, yellowish, or reddish-pink in color.  Little is known about the life cycle of the plant due to its rarity, but it probably obtains its nutrients by parasitizing fungi, so it lacks the green of chlorophyll.  It grows from a rhizome with fragile roots and its form is covered in sparse scales which are the rudimentary leaves.  An inflorescence emerges on a thick stalk from the soil bearing solitary to densely bunched flowers.  The flowers have ragged yellowish or pinkish petals and contain hairs and large rounded yellow stigmas.  The fruit is a fleshy white berry.

Perennial plant: A perennial plant or simply perennial is a plant that lives for more than two years.  The term ("per-" + "-ennial", "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials.  The term is also widely used to distinguish plants with little or no woody growth from trees and shrubs, which are also technically perennials.

Salvia indica: Salvia indica is a species of herbaceous perennial plant belonging to the family Lamiaceae.  It is native to a wide region of Western Asia that includes Israel, Iraq, Iran and Turkey.  It was first described by the taxonomist Carl Linnaeus in 1753.  It is unknown why he gave it the specific epithet "indica", since the plant is not from India.  While "Salvia indica" is classified as a herbaceous perennial, in cultivation individual plants often live no longer than two years.

Stylophorum diphyllum: Stylophorum diphyllum (celandine-poppy, wood poppy, poppywort) is a herbaceous perennial native to moist woodland in eastern North America, valued for its yellow flowers.  The common name is derived from greater celandine ("Chelidonium majus"), a closely related European plant with similarly shaped leaves and similarly coloured and shaped flowers.

Duranta: Duranta is a genus of flowering plants in the verbena family, Verbenaceae.  It contains 17 species of shrubs and small trees that are native from southern Florida to Mexico and South America.  They are commonly cultivated as hedges and ornamental plants.

Liatris pycnostachya: Liatris pycnostachya (prairie blazing star) is a perennial plant native to the tallgrass prairies of the United States.  "Liatris pycnostachya" is an erect perennial found in tallgrass prairie remnants in the Midwestern and Eastern United States.  The plant reaches 1-3 ft in height "with numerous ascending linear leaves and magnificient, showy, compact spikes of rose pink blossoms.

Chelidonium: Chelidonium majus, commonly known as greater celandine or tetterwort,(although tetterwort also refers to "Sanguinaria canadensis"), nipplewort, or swallowwort, is a herbaceous perennial plant, the only species in the genus Chelidonium.  It is native to Europe and western Asia and introduced widely in North America.

Origanum dictamnus: Origanum dictamnus (dittany of Crete, Cretan dittany or hop marjoram), known in Greek as "δίκταμο" ("díktamo", cf. "dittany") or in Cretan dialect "έρωντας" ("erontas", "love"), is a tender perennial plant that grows 20–30 cm high.  It is a healing, therapeutic and aromatic plant that only grows wild on the mountainsides and gorges of the Greek island of Crete, Greece.  The dittany of Crete is widely used for food flavouring and medicinal purposes, in addition to it featuring as an ornamental plant in gardens.  This small, lanate shrub is easily recognised by the distinctive soft, woolly covering of white-grey hair on its stems and round green leaves, giving it a velvety texture.  Tiny rose-pink flowers surrounded by brighter purple-pink bracts add an exuberant splash of colour to the plant in summer and autumn.  The dittany is classified as vulnerable on the IUCN Red List of Threatened Plant Species 1997.

Stylidium dunlopianum: Stylidium dunlopianum is a dicotyledonous plant that belongs to the genus "Stylidium" (family Stylidiaceae).  It is an erect perennial plant that grows from 15 to 50 cm tall.  Obovate leaves, about 6-12 per plant, form a basal rosette with some scattered along the stem.  The leaves are generally 20–60 mm long and 7–19 mm wide.  This species generally has one to five scapes and cymose inflorescences that are 13–40 cm long.  Flowers are pink or mauve.  "S. dunlopianum"'s distribution ranges from the Mitchell River area in Western Australia east to the Kakadu National Park in the Northern Territory.  Its typical habitats include sandy or black organic soils along creekbanks, near rainforests, or in seepage areas in "Melaleuca leucadendra" swamps.  It flowers in the southern hemisphere from May to November.  "S. dunlopianum" is most closely related to "S. rotundifolium", but differs most significantly by its thickened stem base and growth habit.  "S. dunlopianum" is a perennial whereas "S. rotundifolium" is an annual.  Its conservation status has been assessed as data deficient.

Ipomopsis tenuituba: Ipomopsis tenuituba is a species of flowering plant in the phlox family known by the common name slendertube skyrocket, or slendertube ipomopsis.  It is native to much of the western United States from California to Colorado, where it is found on rocky mountain slopes.  This is a perennial herb producing an erect stem with widely spaced leaves, each 3 to 6 centimeters long and with many narrow, fingerlike lobes.  The inflorescences toward the top of the stem each hold three to seven flowers.  The flower is very pale to medium pink, sometimes with white streaks, or solid white.  It is a tube 2 to 5 centimeters long, opening into a corolla of five twisting, pointed, ribbonlike lobes.  The stamens and style do not protrude far from the mouth of the flower, if at all.  While it is a perennial plant, it dies after its first flowering.
