Cold hardening is a process in which a plant undergoes physiological changes to avoid, or mitigate cellular injuries caused by sub-zero temperatures. [1] Non-acclimatized individuals can survive −5 °C, while an acclimatized individual in the same species can survive −30 °C. Plants that originated in the tropics, like tomato or maize, don ...
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.
Plants trimmed to 15–61 cm (6–24 in) in early spring provide the best subsequent growth and flowering. [5] [65] Tolerant of both heat and cold, it is grown in North America in United States Department of Agriculture hardiness zones three through nine, [10] [59] although some cultivars may be better suited than others to extremes of temperature.
Salvia clevelandii flower. Salvia clevelandii, the fragrant sage, [3] blue sage, [citation needed] Jim sage, [citation needed] Cleveland sage, [4] and Cleveland's blue sage [1] is a perennial plant of family Lamiaceae native to Southern California and northern Baja California, growing below 900 m (3,000 ft) elevation [not verified in body] in California coastal sage and chaparral habitat.
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.
H1a, higher than 15 °C (59 °F), applies to tropical plants permanently under glass in heat; while H7, below −20 °C (−4 °F), applies to very cold-tolerant plants such as heathers. Most outdoor plants in the UK fall within the range H4, −10 to −5 °C (14 to 23 °F) (hardy in the average winter) to H5, −15 to −10 °C (5 to 14 °F ...
Salvia (/ ˈ s æ l v i ə /) [4] is the largest genus of plants in the sage family Lamiaceae, with just under 1,000 species of shrubs, herbaceous perennials, and annuals. [5] [6] [7] Within the Lamiaceae, Salvia is part of the tribe Mentheae within the subfamily Nepetoideae. [5]
Salvia spathacea, the California hummingbird sage or pitcher sage, [2] is a species of flowering plant in the family Lamiaceae, native to southern and central California growing from sea level to 610 m (2,001 ft). This fruity scented sage blooms in March to May with typically dark rose-lilac colored flowers.
