Penstemon, the beardtongues, is a large genus of roughly 280 species of flowering plants native mostly to the Nearctic, but with a few species also found in the North American portion of the Neotropics. It is the largest genus of flowering plants endemic to North America. As well as being the scientific name, penstemon is also widely used as a common name for all Penstemon species alongside beardtongues.
Scilla is a genus of about 30 to 80 species of bulb-forming perennial herbaceous plants in the family Asparagaceae, subfamily Scilloideae. Sometimes called the squills in English, they are native to woodlands, subalpine meadows, and seashores throughout Europe, Africa and the Middle East. A few species are also naturalized in Australasia and North America. Their flowers are usually blue, but white, pink, and purple types are known; most flower in early spring, but a few are autumn-flowering. Several Scilla species are valued as ornamental garden plants.
Aubrieta is a genus of about 20 species of flowering plants in the cabbage family Brassicaceae. The genus is named after Claude Aubriet, a French flower painter. It originates from southern Europe east to central Asia but is now a common garden escape throughout Europe. It is a low, spreading plant, hardy, evergreen and perennial. It has small violet, pink, or white flowers, and it inhabits rocks and banks. It prefers light, well-drained soil, is tolerant of a wide pH range, and can grow in partial shade or full sun.
Hesperis is a genus of flowering plants in the family Brassicaceae. Most are native to Eurasia, with several endemic to Greece and Turkey. Many plants of this genus bear showy, fragrant flowers in shades of purple and white. One of the more widely known species is the common garden flower Hesperis matronalis. The genus name Hesperis was probably given because the scent of the flowers becomes more conspicuous towards evening.
Scilla siberica, the Siberian squill or wood squill, is a species of flowering plant in the family Asparagaceae, native to southwestern Russia, the Caucasus, and Turkey. Despite its name, it is not native to Siberia.
Hyacinthoides hispanica, the Spanish bluebell or wood hyacinth, is a spring-flowering bulbous perennial native to the Iberian Peninsula. It is one of around a dozen species in the genus Hyacinthoides, others including the common bluebell in northwestern Europe, and the Italian bluebell further east in the Mediterranean region.
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Linnaeus' Species Plantarum of 1753. Botanical nomenclature is governed by the International Code of Nomenclature for algae, fungi, and plants (ICN), which replaces the International Code of Botanical Nomenclature (ICBN). Fossil plants are also covered by the code of nomenclature.
Scilla luciliae is a species of flowering plant in the family Asparagaceae. It is referred to by the common names Bossier's glory-of-the-snow or Lucile's glory-of-the-snow, and is a bulbous perennial from western Turkey that flowers in early spring. After flowering, it goes into dormancy until the next spring. The specific epithet is in honour of Lucile, the wife of the Swiss botanist Pierre Edmond Boissier (1810-1885). It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, and may now be treated as Scilla sect. Chionodoxa.
Hyacinthoides italica, the Italian bluebell or Italian squill, is a spring-flowering bulbous perennial plant belonging to the family Asparagaceae.
Scilla section Chionodoxa, known as glory-of-the-snow, is a small group of bulbous perennial flowering plants in the family Asparagaceae, subfamily Scilloideae. Formerly treated as the separate genus Chionodoxa, they are now included in Scilla as a section. The section is endemic to the eastern Mediterranean, specifically Crete, Cyprus and Turkey. The blue, white or pink flowers appear early in the year making them valuable garden ornamentals. The common name of the group is based on the habit of flowering in high alpine zones when the snow melts in spring.
Scilla forbesii, known as Forbes' glory-of-the-snow, is a bulbous perennial plant from west Turkey flowering in early spring. It is considered synonymous with Scilla siehei, known as Siehe's glory-of-the-snow, by some sources, although others distinguish them. It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, and may now be treated as Scilla sect. Chionodoxa. After flowering, it goes into dormancy until the next spring. It seeds readily to form colonies.
Scilla sardensis, the lesser glory-of-the-snow, is a bulbous perennial from west Turkey flowering in early spring. After flowering, it goes into dormancy until the next spring. It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, and may now be treated as Scilla sect. Chionodoxa.
Scilla nana, known as dwarf glory-of-the-snow, is a bulbous perennial flowering plant endemic to Crete. It flowers in early spring with flowers in shades of lilac blue. After flowering, it goes into dormancy until the next spring. It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, and may now be treated as Scilla sect. Chionodoxa. It has not always been recognized as distinct from Scilla cretica.
Scilla lochiae, known as Loch's glory-of-the-snow, is a bulbous perennial from Cyprus flowering in early spring. After flowering, it goes into dormancy until the next spring. It was named after Lady Loch who collected it. It belongs to a group of Scilla species that were formerly put in a separate genus, Chionodoxa, which may now be treated as Scilla sect. Chionodoxa.
Scilla bifolia, the alpine squill or two-leaf squill, is a herbaceous perennial plant growing from an underground bulb, belonging to the genus Scilla of the family Asparagaceae.
Scilla × allenii is a hybrid between two species of flowering plants, both of which are now placed in the genus Scilla. One of the parents is Scilla bifolia. As of March 2020, sources differ as to the identity of the other, which may be either Scilla forbesii or Scilla luciliae.
Scilla litardierei, the amethyst meadow squill or Dalmatian scilla, is a species of flowering plant in the family Asparagaceae. A bulbous perennial, with blue grape-hyacinth like flowers, blooming in late spring, much later than the more popular Siberian squill and later than Muscari which it resembles.
Iris stenophylla is a species of flowering plant in the genus Iris, it is also in the subgenus Scorpiris. It is a bulbous perennial.
