Question 1

What is a plant's Latin name telling you?

Accepted Answer

Rather a lot, once you know what each part of it does — and it is the only reliable way to buy the plant you actually want, because common names are inconsistent and frequently shared between unrelated plants.

**The two-part core.** *Lavandula angustifolia*.

**The genus** comes first, capitalised — the group of closely related plants. *Lavandula* is lavender.

**The species** comes second, lowercase — the specific plant within that group. *angustifolia* means narrow-leaved.

Both are italicised, by convention.

**What the species name frequently tells you.** These are descriptive Latin, and a small vocabulary goes a long way: *officinalis* (used medicinally), *vulgaris* (common), *sylvestris* (of woodland), *palustris* (of marshes — it wants damp), *repens* (creeping), *nana* (dwarf), *grandiflora* (large-flowered), *sempervirens* (evergreen), *japonica* / *sinensis* / *chinensis* (origin), *alba* / *rubra* / *lutea* (white, red, yellow), *maritima* (coastal, so likely salt- and wind-tolerant).

**The additions after the species:**

**'Hidcote'** — single quotation marks, not italicised, capitalised. This is a **cultivar**: a cultivated variety selected and propagated by people. It will be genetically consistent, and it is what determines the actual colour, size and habit you get.

**var.** — a naturally occurring **variety**, differing from the species in the wild.

**subsp.** — subspecies, usually a geographically distinct population.

**× (a multiplication sign)** — a hybrid. *Lavandula × intermedia* is a cross.

**f.** — a minor form.

**AGM** on a label is not part of the name — it is the RHS **Award of Garden Merit**, indicating the plant performed reliably in trials, and it is genuinely useful.

**Why it matters practically.** "Bluebell" means different plants in different countries. Buying *Hyacinthoides non-scripta* gets you the native English one rather than the invasive Spanish species. And the **cultivar name is the part most often dropped by cheap sellers**, which is how you end up with a lavender that grows twice the expected size.

Question 2

What can you actually grow in a shady garden?

Accepted Answer

A great deal — provided you first establish what kind of shade you have, because the word covers conditions that are completely different from a plant's point of view. The distinctions that matter:

Question 3

What does "hardy" actually mean on a plant label?

Accepted Answer

It describes a plant's ability to survive cold, and the labels are more specific than most people realise — but they are also a simplification of something with several variables. The RHS hardiness

Question 4

Why is my lavender dying?

Accepted Answer

Nearly always too much water, too rich a soil, or the wrong pruning — and often all three. Lavender is a Mediterranean plant, and most of the ways people look after it are actively harmful. Drainage

Question 5

What are mycorrhizal fungi, and do root boosters work?

Accepted Answer

Mycorrhizal fungi form a genuine partnership with plant roots, and the biology is well established. Whether the products sold in garden centres do anything useful is a much narrower question, and the

Question 6

How do you plan a garden for year-round interest?

Accepted Answer

By designing around structure first and flowers last — because a garden that depends on flowers is compelling for a few weeks and empty for the rest of the year, which is the most common failing in

Question 7

What does full sun actually mean on a plant label?

Accepted Answer

Six or more hours of direct, unobstructed sunlight a day during the growing season. "Direct" is the operative word — bright ambient daylight in an open but shaded spot does not count. The standard
