How to identify a wildflower

Use visible features to narrow down the family and species.

Wildflowers do not always grow where a habitat guide says they should. Habitat and flowering time are useful clues, but the plant itself usually gives you stronger evidence. This guide shows what to look at first.

A simple identification route

You do not need to recognise everything at once. Work through a few visible features and use several clues together.

  1. 1

    Look at the flower arrangement

    Is there one obvious flower, or a group of flowers? Look for an umbel, raceme, spike, cyme, panicle or capitulum.

  2. 2

    Study the shape of one flower

    Is it open and regular, bell-shaped, tubular, pea-shaped or two-lipped? Does it look the same around the centre, or does it have a definite top and bottom? See the illustrated flower-shapes guide →

  3. 3

    Count the flower parts

    Count petals or petal lobes, sepals and visible stamens. Notice whether petals are separate or joined into a corolla tube.

  4. 4

    Check the leaves

    Are they alternate, opposite or whorled? Do they form a basal rosette? Look at shape, divisions and whether the edge is smooth or toothed.

  5. 5

    Look at the stem and small details

    Is the stem round or square, hollow or solid, smooth or hairy? Check for bracts, stipules, hairs and the way leaves join the stem.

  6. 6

    Use season and habitat as supporting clues

    Where the plant is growing and when it is flowering can narrow the possibilities, but neither should override the structural features you can see on the plant.

Flower arrangements worth learning

Raceme

An unbranched central axis bears individual stalked flowers. Foxglove has a raceme-like flowering spike.

See Foxglove →

Solitary or simple flowers

Some plants are easier to read one flower at a time. Count the flower parts and examine how petals, sepals and stamens are arranged.

Do not ignore the leaves

Flowers attract attention, but leaves can separate species that otherwise look surprisingly similar.

Arrangement

Alternate, opposite, whorled, or concentrated in a basal rosette.

Shape

Look for shapes such as ovate, elliptic and lanceolate.

Division

A leaf may be simple, lobed or compound. A pinnate leaf has leaflets arranged along a central axis.

Margins and stalks

Check whether the edge is entire or serrate, and whether the leaf has a petiole or is sessile.

Use the family as a shortcut

Once several features point towards the same family, the number of likely species becomes much smaller. These are useful starting patterns rather than rules that every member follows perfectly.

Apiaceae

Carrot family

Small flowers in umbels, often with divided leaves and leaf bases that sheath the stem.

Example: Cow Parsley

Asteraceae

Daisy family

What looks like one flower is usually a head made from many tiny florets.

Example: Oxeye Daisy, Common Knapweed

Fabaceae

Pea family

Distinctive pea-shaped flowers are common, often followed by a pod; leaves are frequently compound.

Example: Red Clover

Ranunculaceae

Buttercup family

A varied family, but many species have numerous stamens and several separate carpels.

Example: Wood Anemone, Lesser Celandine

Caryophyllaceae

Pink family

Leaves are usually opposite and flowers commonly have five petals, often notched or divided.

Example: Red Campion

Plantaginaceae

Plantain family

Often has fused petals forming a tube or two-lipped flower; many species have four stamens.

Example: Foxglove

Primulaceae

Primrose family

Five petal lobes are typically joined at the base into a corolla tube.

Example: Primrose

Plumbaginaceae

Leadwort family

Usually five-parted flowers, with simple leaves that are often gathered into a basal rosette.

Example: Thrift
