Salvia coccinea

Salvia coccinea is a science 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 coccinea rather than just read about it. In short: Salvia coccinea, the blood sage, scarlet sage, Texas sage, or tropical sage, 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). At one time Brazil was considered to be where it originated, but its diploid chromosome count now points to Mexico as its place of or…

Key takeaways

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

Reference excerpt

Salvia coccinea, the blood sage, scarlet sage, Texas sage, or tropical sage, 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). At one time Brazil was considered to be where it originated, but its diploid chromosome count now points to Mexico as its place of origin.

Taxonomy Its specific epithet, coccinea, means "scarlet-dyed" (Latin), referring to the color of its flowers.

Description The plant reaches 2 to 4 ft (0.61 to 1.22 m) in height, with many branches, and a spread of about 2.5 ft (0.76 m). The hairy leaves, scalloped on the edges, are pea green, varying in size, all the way up to 3 in (7.6 cm) long and 2 in (5.1 cm) wide. Flower color and size is quite variable. The naturalized variety is typically tubular, bright red, about 1.25 in (3.2 cm) long. Flowers are pollinated by hummingbirds and butterflies.

Cultivation Salvia coccinea is commonly grown as an annual species. It is cultivated in urban green areas as well as in private gardens around the world. It has a long flowering period, from the start of summer to the end of autumn. Cultivated varieties include orange-red, pink, salmon, red, white, and scarlet, as well as bi-colored varieties. The plant can survive winter in USDA Hardiness Zones Zones 8–10.

Worked examples

Example 1 — a first encounter with Salvia coccinea

Start with the simplest possible case. Write down what Salvia coccinea claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 coccinea 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 coccinea 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 coccinea

In research: Salvia coccinea appears in science 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 coccinea 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 coccinea is common in secondary-school and first-year university syllabi. It links to neighbouring topics Butterfly food plants, Flora of Brazil, Flora of Central America, so understanding it makes those chapters shorter.
In everyday life: Look for Salvia coccinea 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.
