Lavatera is a genus of about 25 species of flowering plants in the family Malvaceae, native to the Mediterranean region, central and eastern Asia, North America (California and Mexico) and Australia. A number of species are naturalized in North America.
Many Lavatera species have now been transferred to the related genus Malva. Lavatera species are known as tree mallows, or rather ambiguously as rose mallows, royal mallows or annual mallows.
The genus includes annual, biennial and perennial herbaceous plants and soft-wooded shrubs, growing from 1–3 m tall. The leaves are spirally arranged, and palmately lobed. The flowers are conspicuous, 4–12 cm diameter, with five white, pink or red petals; they are produced in terminal clusters.
Lavatera species are used as food plants by the larvae of some Lepidoptera species including Bucculatrix lavaterella, which feeds exclusively on these plants. Flowers and seeds of several species are also used as food by humans.

Rudbeckia /rʌdˈbɛkiə/ is a plant genus in the sunflower family. The species are commonly called coneflowers and black-eyed-susans; all are native to North America and many species are cultivated in gardens for their showy yellow or gold flower heads.
The species are herbaceous, mostly perennial plants (some annual or biennial) growing to 0.5–3 m tall, with simple or branched stems. The leaves are spirally arranged, entire to deeply lobed, 5–25 cm long. The flowers are produced in daisy-like inflorescences, with yellow or orange florets arranged in a prominent, cone-shaped head; "cone-shaped" because the ray florets tend to point out and down (are decumbent) as the flower head opens.
A large number of species have been proposed within Rudbeckia, but most are now regarded as synonyms of the limited list given below.
Several currently accepted species have several accepted varieties. Some of them (for example the Black-eyed Susan, R. hirta), are popular garden flowers distinguished for their long flowering times. There are many cultivars of these species.
Rudbeckia species are eaten by the caterpillars of some Lepidoptera species including Cabbage Moth and Dot Moth.

Salpiglossis sinuata, the painted tongue, scalloped tube tongue, or velvet trumpet flower, is a flowering plant in the family Solanaceae, native to southern Chile.
Salpiglossis sinuata is an annual or short-lived perennial herbaceous plant growing to 60 cm (2.0 ft) tall, rarely up to 1 m (3.3 ft) tall. The leaves are 4–10 cm (1.6–3.9 in) long, elliptic to lanceolate, with a wavy, lobed or toothed margin.
The flowers have a five-lobed funnel-shaped corolla, up to 7 cm (2.8 in) long and 5.5 cm (2.2 in) diameter, each lobe with a notched apex, velvety in texture, either violet or orange, and have contrasting darker stripes along each petal.

Of the two species in its genus, Salpiglossis sinuata is the more commonly grown as an ornamental plant for gardens. It was introduced to the northern hemisphere in the 1820s.
A number of cultivars have been selected for different flower colours. It is grown in full sunlight.

Dahlia (UK /deɪliə/ or US /dɑːliə/) is a genus of bushy, tuberous, herbaceous perennial plants native to Mexico. A member of the Asteraceae (or Compositae), dicotyledonous plants, related species include the sunflower, daisy,chrysanthemum, and zinnia. There are 42 species of dahlia, with hybrids commonly grown as garden plants. Flower forms are variable, with one head per stem; these can be as small as 5 cm (2 in) diameter or up to 30 cm (1 ft) ("dinner plate"). This great variety results from dahlias being octoploids—that is, they have eight sets of homologous chromosomes, whereas most plants have only two. In addition, dahlias also contain many transposons—genetic pieces that move from place to place upon an allele—which contributes to their manifesting such great diversity.
The stems are leafy, ranging in height from as low as 30 cm (12 in) to more than 1.8–2.4 m (6–8 ft). The majority of species do not produce scented flowers or cultivars. Like most plants that do not attract pollinating insects through scent, they are brightly colored, displaying most hues, with the exception of blue.
The dahlia was declared the national flower of Mexico in 1963. The tubers were grown as a food crop by the Aztecs, but this use largely died out after the Spanish Conquest. Attempts to introduce the tubers as a food crop in Europe were unsuccessful.

Dahlias are perennial plants, with mostly tuberous roots. While some have herbaceous stems, others have stems which lignify in the absence of secondary tissue and resprout following winter dormancy, allowing further seasons of growth. As a member of the Asteraceae the flower head is actually a composite (hence the older name Compositae) with both central disc florets and surrounding ray florets. Each floret is a flower in its own right, but is often incorrectly described as a petal, particularly by horticulturalists. The modern name Asteraceae refers to the appearance of a star with surrounding rays.

Coreopsis /ˌkɒriːˈɒpsᵻs/ is a genus of flowering plants in the family Asteraceae. Common names include calliopsis and tickseed, a name shared with various other plants.

They range from 46–120 cm (18–47 in) in height. The flat fruits are small and dry and look like bugs. Many of its species are cultivated. The 75 to 80 Coreopsis species are native to North, Central, and South America. The flowers are usually yellow with a toothed tip. They have showy flower heads with involucral bracts in two distinct series of eight each, the outer being commonly connate at the base. The name Coreopsis is derived from the Greek words κόρις (koris), meaning "bedbug," and ὄψις (opsis), meaning "view," referring to the shape of the achene.

Coreopsis species are used as food plants by the caterpillars of some Lepidoptera species including Coleophora acamtopappi. The sunny, summer blooming, yellow daisy-like flowers are popular in gardens to attract butterflies.
All Coreopsis species were designated the state wildflower of Florida in the United States in 1991.

Coreopsis is a variable genus closely related to Bidens. In fact, neither Coreopsis nor Bidens, as defined in the 20th century, is strictly monophyletic. Coreopsis is best described as paraphyletic. Previously (1936) Coreopsis was classified into 11 sections and 114 species, but the African species were subsequently reclassified as Bidens, leaving the North and South American species under Coreopsis, some 75-80 in all. 45 are in the 11 North American sections, and the remaining 35 are in the South American Section Pseudoagarista. The North American species fall into two broad groups, with 5 sections in Mexico and North America (12 species) and the remaining 5 sections in Eastern North America (26 species). 
One group which does seem to be monophyletic consists of temperate species from North America, including five sections of Coreopsis, Bidens coronata and Bidens tripartita, and the genus Thelesperma (five species).
