Salvia clevelandii

Salvia clevelandii is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Salvia clevelandii rather than just read about it. In short: Salvia clevelandii, the fragrant sage, blue sage, Jim sage, Cleveland sage, and Cleveland's blue sage is a perennial plant of family Lamiaceae native to Southern California and northern Baja California, growing below 900 m (3,000 ft) elevation in California coastal sage and chaparral habitat. The plant was named in 1874 by Asa Gray, honoring plant collector Daniel Cleveland.

Key takeaways

Salvia clevelandii belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Salvia clevelandii to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Salvia clevelandii from memory before moving on to harder problems.

Reference excerpt

Salvia clevelandii, the fragrant sage, blue sage, Jim sage, Cleveland sage, and Cleveland's blue sage is a perennial plant of family Lamiaceae native to Southern California and northern Baja California, growing below 900 m (3,000 ft) elevation in California coastal sage and chaparral habitat. The plant was named in 1874 by Asa Gray, honoring plant collector Daniel Cleveland.

Description

Salvia clevelandii is an evergreen shrub that reaches 1 to 1.5 m (3.3 to 4.9 ft) in height and width. The fragrant, ashy green leaves are obovate and rugose, growing less than 2.5 cm (0.98 in) long. Flowers are on 30 cm (12 in) spikes, with numerous whorls of upright amethyst blooms opening in June–July.

Phytochemistry The rose potpourri scented foliage of hybrids is composed of camphor and 1,8-cineole. Named cultivars with a eucalyptus scent also contain around 20% 1,8-cineole.

Taxonomy Salvia clevelandii was described in 1874 as Audibertia clevelandii (the basionym) by Asa Gray, named in honor of Daniel Cleveland. Cleveland was an amateur botanist and civic leader from San Diego, who had taken an interest in the local flora and fauna, sending his collections to Gray over a 20-year correspondence. In the wild, this species may hybridize with Salvia apiana and Salvia mellifera.

Distribution and habitat Salvia clevelandii is found throughout portions of Southern California and northwestern Baja California, in chaparral and coastal sage scrub. It is distributed along the coast of San Diego County, the Peninsular Ranges of San Diego and Orange counties, and in northwestern Baja California, from the border to the northern portion of the central desert in the southern Sierra de San Pedro Martir.

Cultivation Salvia clevelandii is a popular Southwest US landscape plant, cultivated since the 1940s. Plants prefer dry summers, good drainage, and tolerate full sun in cooler areas. As a landscape plant they have a relatively short life span of five to ten years. They are hardy to −7 °C (19 °F). Cultivars and hybrids include:

'Winnifred Gilman', a popular cultivar with intense violet-blue flowers. 'Betsy Clebsch', a shorter cultivar with wide variation in flower color. 'Allen Chickering', 'Aromas', 'Pozo Blue', 'Santa Cruz Dark', and 'Whirly Blue' are hybrids with similar appearance. Salvia clevelandii is one of the parents of the hybrid Salvia 'Celestial Blue'.

Worked examples

Example 1 — a first encounter with Salvia clevelandii

Start with the simplest possible case. Write down what Salvia clevelandii claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Salvia clevelandii before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Salvia clevelandii ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Salvia clevelandii

In research: Salvia clevelandii appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Salvia clevelandii in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Salvia clevelandii is common in secondary-school and first-year university syllabi. It links to neighbouring topics Butterfly food plants, Drought-tolerant plants, Flora of Baja California, so understanding it makes those chapters shorter.
In everyday life: Look for Salvia clevelandii outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
