Remontancy

Remontancy 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 Remontancy rather than just read about it. In short: Remontancy is the ability of a plant to flower more than once during the course of a growing season or year. It is a term applied most specifically to roses, and roses possessing this ability are called "repeat flowering" or remontant.

Key takeaways

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

Reference excerpt

Remontancy is the ability of a plant to flower more than once during the course of a growing season or year. It is a term applied most specifically to roses, and roses possessing this ability are called "repeat flowering" or remontant. The term originated in the nineteenth century from the French verb remonter or 'coming up again'. Roses which lack this ability are termed "summer flowering", "once flowering" or non-remontant. Few wild rose species possess remontancy; notable exceptions being Rosa chinensis, Rosa rugosa and Rosa fedtschenkoana. As remontancy is considered a desirable horticultural characteristic, it is preferentially selected for by rose hybridisers. Remontant roses descended from Rosa chinensis have been grown in China for at least a thousand years, but the first garden roses in Europe to possess remontancy were the autumn damasks, which first appeared in the seventeenth century with the introduction of the cultivar 'Quatre Saisons'. Recent DNA research has shown that these damask roses resulted from crosses involving Rosa gallica, Rosa moschata and the remontant central Asian species Rosa fedtschenkoana. When forms of Rosa chinensis were introduced into Europe in the late eighteenth century, subsequent hybridisation between these and the European roses eventually led to the wide variety of remontant garden hybrids which are available today.

Worked examples

Example 1 — a first encounter with Remontancy

Start with the simplest possible case. Write down what Remontancy 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 Remontancy 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 Remontancy 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 Remontancy

In research
Remontancy 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 Remontancy 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
Remontancy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flowers, so understanding it makes those chapters shorter.
In everyday life
Look for Remontancy 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.

Frequently asked questions

What is Remontancy in simple terms?

Remontancy is the ability of a plant to flower more than once during the course of a growing season or year. It is a term applied most specifically to roses, and roses possessing this ability are called "repeat flowering" or remontant.

Why does Remontancy matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Remontancy?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
