A daylily, day lily or ditch-lily is a flowering plant in the genus Hemerocallis, a member of the family Asphodelaceae, subfamily Hemerocallidoideae, native to Asia. Despite the common name, it is not, in fact, a lily, nor does it specifically grow in ditches. Gardening enthusiasts and horticulturists have long bred Hemerocallis species for their attractive flowers; a select few species of the genus have edible petals, while some are extremely toxic. Thousands of cultivars have been registered by the American Daylily Society, the only internationally recognized registrant according to the International Code of Nomenclature for Cultivated Plants (ICNCP).. The plants are perennial, bulbous plants, whose common name alludes to its flowers, which typically last about a day.
Alstroemeria, commonly called the Peruvian lily or lily of the Incas, is a genus of flowering plants in the family Alstroemeriaceae. They are all native to South America, although some have become naturalized in the United States, Mexico, Australia, New Zealand, Madeira and the Canary Islands. Almost all of the species are restricted to one of two distinct centers of diversity; one in central Chile, the other in eastern Brazil. Species of Alstroemeria from Chile are winter-growing plants, while those of Brazil are summer growing. All are long-lived perennials except A. graminea, a diminutive annual from the Atacama Desert of Chile.
Fritillaria meleagris is a Eurasian species of flowering plant in the lily family Liliaceae. Its common names include snake's head fritillary, snake's head, chess flower, frog-cup, guinea-hen flower, guinea flower, leper lily, Lazarus bell, chequered lily, chequered daffodil, drooping tulip or, in the British Isles, simply fritillary. The plant is a bulbous perennial native to the flood river plains of Europe where it grows in abundance.

Cornus alba, the red-barked, white or Siberian dogwood, is a species of flowering plant in the family Cornaceae, native to Siberia, northern China and Korea. It is a large deciduous surculose (suckering) shrub that can be grown as a small tree. As a popular ornamental used in landscaping its notable features include the red stems in fall (autumn) through late winter, bright winter bark; and the variegated foliage in some cultivars, such as C. alba 'Elegantissima'. C. alba can grow to 3 m (10 ft) high, but variegated forms are less vigorous. For the brightest winter bark, young shoots are encouraged by cutting to the ground some older stems at the end of the winter, before leaves are open. The oval fruits are white, sometimes tinted blue.

These bear umbels of 8-10 narrowly-flared, pendulous tubular flowers in shades of red, green and cream in spring and summer. The umbels are bent over in a curious crook or sickle shape. The plant goes dormant in winter. The bulb, shaped like a bowling pin, rests with its neck above the soil line.
Hypericum kouytchense, the large-flowered St John's wort, is a species of flowering plant in the family Hypericaceae, native to Western China. Growing up to 3 ft (0.91 m) tall and 5 ft (1.5 m) wide, it is a semi-evergreen rounded shrub with blue-green leaves and large yellow flowers with prominent stamens, appearing in midsummer. Flowers are followed by red seed capsules in autumn. Where conditions are favourable it can retain its leaves all year.
Massonia depressa, the hedgehog lily, is a species of flowering plant in the family Asparagaceae. It is a bulbous geophyte native to the Cape Provinces and Free State of South Africa. Growing to 10 cm (3.9 in) tall by 50 cm (20 in) broad, it is a bulbous perennial with two opposite leaves lying flat on the ground. A spiky cluster of white, yellow or brown flowers appears at the centre of the plant in winter. The flowers are uniquely scented like yeast, to attract pollination by gerbils and other rodents. The anther is exceptionally long - up to 2mm. The seed capsules are inflated, enabling them to be wind-borne.
