Lycoris squamigera [Resurrection Lily, Surprise Lily, Magic Lady] is a plant in the amaryllis family, Amaryllidaceae, subfamily Amaryllidoideae.
Lycoris squamigera is believed to have originated in Japan or China, perhaps a hybrid between Lycoris straminea and Lycoris incarnata. It is a herbaceous plant with basal, simple leaves, which are not present when the flowers emerge from the crown. The leaves sprout and grow in the spring, then die back during June. Then in late July or early August the flowers appear. The flowers are white or pink and fragrant. The flowers spring dramatically from the ground in mid to late summer; it usually takes only four to five days from first emergence to full bloom. This suddenness is reflected in its common names: surprise lily, magic lily, and resurrection lily. It is also sometimes referred to as naked ladies. In Japanese it is called kitsune no kamisori which means fox’s razor.

Lycoris radiata [red spider lily] is a plant in the amaryllis family, Amaryllidaceae, subfamily Amaryllidoideae. Originally from China, it was introduced into Japan and from there to the United States and elsewhere. It flowers in the late summer or autumn, often in response to heavy rainfall.
The common name hurricane lily refers to this characteristic, as do other common names, such as resurrection lily; these may be used for the genus as a whole.
Lycoris radiata is a bulbous perennial. It normally flowers before the leaves fully appear, on stems 30–70 cm [12–28 in] tall. The leaves are parallel-sided, 0.5–1 cm [0.20–0.39 in] wide with a paler central stripe. The red flowers are arranged in umbels. Individual flowers are irregular, with narrow segments which curve backwards, and long projecting stamens.

Convallaria majalis, commonly known as the Lily of the Valley, is a sweetly scented [and highly poisonous] woodland flowering plant that is native throughout the cool temperate Northern Hemisphere in Asia, Europe and in the southern Appalachian Mountains in the United States. In the APG III system, the genus is placed in the family Asparagaceae, subfamily Nolinoideae [formerly the family Ruscaceae].
Convallaria majalis is a herbaceous perennial plant that forms extensive colonies by spreading underground stems called rhizomes. The stems grow to 15–30 cm tall, with one or two leaves 10–25 cm long, flowering stems have two leaves and a raceme of 5–15 flowers on the stem apex. The flowers are white tepals [rarely pink], bell-shaped, 5–10 mm diameter, and sweetly scented.
Convallaria majalis is a popular garden plant, grown for its scented flowers and for its ground-covering abilities in shady locations.

Fritillaria meleagris is a species of flowering plant in the family Liliaceae. Its common names include snake’s head fritillary, snake’s head [the original English name], chess flower, frog-cup, guinea-hen flower, leper lily [because its shape resembled the bell once carried by lepers], Lazarus bell, checkered lily or, in northern Europe, simply fritillary.
The name Fritillarea comes from the latin fritillus meaning dice-box, and [possibly] referring to the chequered pattern on the flowers. The name meleagris means ‘spotted like a guinea fowl’. The common name “snake’s head” refers to the somewhat snakelike appearance of the green and brown nodding flower heads. The flower has a chequered pattern in shades of green and purple, maroon, or is sometimes pure white.
Fritillaria meleagris is native to Europe but in many places it is an endangered species that is rarely found in the wild but is commonly grown in gardens.
