Big sagebrush is a coarse, many-branched, pale-grey shrub with yellow flowers and silvery-grey foliage, which is generally 0.5–3 metres (1 + 1 ⁄ 2 –10 feet) tall. [3] A deep taproot 1–4 m (3 + 1 ⁄ 2 –13 ft) in length, coupled with laterally spreading roots near the surface, allows sagebrush to gather water from both surface precipitation and the water table several meters beneath.
Salvia coccinea, the blood sage, [1] scarlet sage, Texas sage, or tropical sage, [2] is a herbaceous perennial in the family Lamiaceae that is widespread throughout the Southeastern United States, Mexico, Central America, the Caribbean, and northern South America (Colombia, Peru, and Brazil). [2]
It is semi-deciduous, depending on the location and severity of drought, shallow rooted, and drought tolerant by leaf curling rather than drought-avoiding through leaf drop. Black sage readily hybridizes with three other coastal scrub Salvias: Salvia apiana (Californian white sage), Salvia leucophylla (San Luis purple sage), and Salvia clevelandii.
It is a crucial part of the community of coastal sage scrub habitat and is frequently widely utilized in restoration initiatives. When planted in full sun, it can reach heights and widths of roughly 4' and 4'. Once established, it may survive without additional water, but will appear happier when watered occasionally in the deep summer.
The plant is a perennial evergreen, with a rounded growth habit and a moderate growth rate. It can tolerate full sun and is adaptable to numerous soil conditions, and is cold hardy down to 15°F. [2] The foliage smells of musk, and the large, pale violet to periwinkle blue flowers are attractive to bees, hummingbirds, and butterflies.
Salvia (/ ˈ s æ l v i ə /) [3] is the largest genus of plants in the sage family Lamiaceae, with nearly 1,000 species of shrubs, herbaceous perennials, and annuals. [4] [5] [6] Within the Lamiaceae, Salvia is part of the tribe Mentheae within the subfamily Nepetoideae. [4]
Salvia yangii, previously known as Perovskia atriplicifolia (/ p ə ˈ r ɒ v s k i ə æ t r ɪ p l ɪ s ɪ ˈ f oʊ l i ə /), and commonly called Russian sage, [2] is a flowering herbaceous perennial plant and subshrub. Although not previously a member of Salvia, the genus widely known as sage, since 2017 it has been included within them.
[citation needed] Some bulbs – such as tulips – need cold winters to bloom, while others – such as freesia – can survive a freezing winter. [citation needed] Many domestic plants are assigned a hardiness zone that specifies the climates in which they can survive. Winter gardens are dependent upon the cultivation of winter-hardy plants.
