Fritillaria imperialis, the crown imperial, imperial fritillary or Kaiser's crown, is a species of flowering plant in the lily family Liliaceae, native to a wide stretch from the Anatolian plateau of Turkey, Iraq and Iran to Afghanistan, Pakistan, Northern India and the Himalayan foothills. It is also widely cultivated as an ornamental and reportedly naturalized in Austria, Sicily, and Washington State, USA.

Digitalis purpurea, the foxglove or common foxglove, is a toxic species of flowering plant in the plantain family Plantaginaceae, native to and widespread throughout most of temperate Europe. It has also naturalised in parts of North America and some other temperate regions. The plant is a popular garden subject, with many cultivars available. It is the original source of the heart medicine digoxin. This biennial plant grows as a rosette of leaves in the first year after sowing, before flowering and then dying in the second year. It generally produces enough seeds, however, so that new plants will continue to grow in a garden setting.
Anemonoides ranunculoides, the yellow anemone, yellow wood anemone, or buttercup anemone, is a species of herbaceous and perennial plant that grows in forests across Europe to western Asia, and less frequently in the Mediterranean region. It is occasionally found as a garden escape.

Nuphar lutea, the yellow water-lily, brandy-bottle, or spadderdock, is an aquatic plant of the family Nymphaeaceae, native to northern temperate and some subtropical regions of Europe, northwest Africa, western Asia, North America, and Cuba. This interesting species found on both sides of the Atlantic Ocean was used as a food source and in medicinal practices from prehistoric times with potential research and medical applications going forward.
Digitalis lanata, vernacularly often called woolly foxglove or Grecian foxglove, is a species of foxglove, a flowering plant in the plantain family Plantaginaceae. It gets its name due to the woolly indumentum of the leaves. D. lanata, like other foxglove species, is toxic in all parts of the plant. Symptoms of digitalis poisoning include nausea, vomiting, severe headache, dilated pupils, problems with eyesight, and convulsions at the worst level of toxicity. The plant is also harmful to other animals.
Sternbergia lutea, the winter daffodil, autumn daffodil, fall daffodil, lily-of-the-field, or yellow autumn crocus, is a bulbous flowering plant in the family Amaryllidaceae, subfamily Amaryllidoideae, in the Narcisseae tribe, which is used as an ornamental plant.

Digitalis × fulva, the strawberry foxglove, is a hybrid species of flowering plant within the family Plantaginaceae. It is a naturally occurring fertile hybrid between the species Digitalis grandiflora and Digitalis purpurea. The species is widely marketed in the UK under the common name strawberry foxglove or its taxonomic synonym Digitalis × mertonensis. The species has been used to produce various cultivars and has gained the Royal Horticultural Society's Award of Garden Merit.
Digitalis obscura, commonly called willow-leaved foxglove or dusty foxglove or spanish rusty foxglove, is a flowering plant native to regions in Spain and Morocco. It is also grown as an ornamental flower. This foxglove is a woody perennial plant belonging to the family Plantaginaceae. Along with the other foxgloves it used to be placed in the figwort family, Scrophulariaceae; however, recent genetic research has moved the genus Digitalis to a larger family. It is similar to many of the foxglove species in its high toxicity and medicinal use as a source for the heart-regulating drug digoxin. Its strikingly distinctive amber- to copper-coloured flowers give the species its name and help distinguish it from other members of the genus.
Rehmannia elata, the Chinese foxglove, is a species of flowering plant in the family Orobanchaceae, native to China. Growing to 150 cm (59 in) tall by 50 cm (20 in) broad, it is an herbaceous perennial with veined, hairy leaves and pink, tubular flowers with darker pink stripes in summer. The flowers bear a superficial resemblance to foxgloves, hence the common name "Chinese foxglove", which is also applied to the whole genus. However this species is not closely related to the true foxglove (Digitalis).
