Question: Are Digitalis and Galium both perennials?

Context paragraphs:
Galium ambiguum: Yolla Bolly bedstraw is a species of plants in the family Rubiaceae, native to British Columbia, northern California and southeastern Oregon.  It has for years been known by the scientific name Galium ambiguum, but under the international rules of nomenclature this use of the name is unacceptable because it was already used for a French plant before Wight applied it to this American species.  The provisional name "Galium stebbinsii" has been suggested, but this is at yet (May 2014) unpublished, so another name could eventually be chosen instead.

Digoxigenin: Digoxigenin (DIG) is a steroid found exclusively in the flowers and leaves of the plants "Digitalis purpurea", "Digitalis orientalis" and "Digitalis lanata" (foxgloves), where it is attached to sugars, to form the glycosides (e.g. Lanatoside C).

Digitalis obscura: Digitalis obscura is a flowering plant, commonly known as the Sunset Foxglove or Willow-leaved Foxglove.  It is native to regions in Spain and Africa, but can be grown as an ornamental flower around the world.  It is a perennial woody 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.)  The Sunset Foxglove is similar to many of the foxglove species in its high toxicity and medicinal use as a source for the heart-regulating drug digitalis.  Its strikingly distinctive amber- to copper-colored flowers give the species its name and help distinguish it from other members of the genus.

Galium migrans: Galium migrans is a species of flowering plant in the family Rubiaceae.  Following a revision of the genus "Galium", the distribution of "Gallium migrans" is now believed to be restricted to South Australia.  Plants in New South Wales that were formerly identified as this species are currently identified as "Galium leptogonium".

Galium: Galium is a large genus of annual and perennial herbaceous plants in the family Rubiaceae, occurring in the temperate zones of both the Northern and Southern Hemispheres.  Some species are informally known as bedstraw.

Digitalis thapsi: Digitalis thapsi, known commonly as Spanish foxglove, Spanish digitalis, and fingerhut foxglove, is a flowering plant in the genus "Digitalis" that is native to Spain.  It was first described by Carl Linnaeus in 1753.  It is of commercial importance as an ornamental plant.  Hybrids with "D. purpurea" have proved successful and are fertile.

Digitalis × fulva: Digitalis" × "fulva, the strawberry foxglove, is a fertile hybrid between "Digitalis grandiflora" and "Digitalis purpurea".

Galium hardhamae: Galium hardhamae (often misspelled ""Galium hardhamiae"") (note added May 2014: "hardhamiae" is the correct spelling per Article 60C1 of the ICN) is a species of flowering plant in the coffee family known by the common name Hardham's bedstraw.  It is endemic to the Santa Lucia Range of southern Monterey County and northern San Luis Obispo County in California.  It is a member of the serpentine soils flora in these coastal mountains.  This is a perennial herb forming mats or clumps of stems no more than 30 centimeters long.  The stems have many whorls of six fleshy green leaves, each leaf just 1 to 3 millimeters long.  The inflorescences, clusters of yellow-green to pinkish flowers, appear in leaf axils.

Digitalis: Digitalis ( or ) is a genus of about 20 species of herbaceous perennials, shrubs, and biennials commonly called foxgloves.

Galium propinquum: Galium propinquum is a plant species of the genus "Galium".
