Foraging

Identifying Elderflower

Use this simple guide to confidently identify elderflower (then make the most fantastic summer drink you’ve ever tasted!):

Tree:
The Elder is a somewhat scraggy, untidy-looking tree which doesn’t usually have a single, main trunk. Instead, several stems tend to emerge from the ground and branch frequently, giving the tree a bushy, shrub-like appearance. I have seen Elder trees approaching 10m (approx 30 feet) in height as well as much smaller specimens measuring just 2m (approx 6 feet) or less.

Location:
Elder trees can be found in parks, woodlands, forests, hedgerows, by the roadside and in many gardens, right across the world.

Flowers:
The Elder tree flowers for approximately 6 weeks in early summer. Sprays or clusters of flowers are dotted all over the tree.

When fully in bloom, each tiny flower is white/cream in colour and has 5 rounded petals, white/cream stamens (stalks) and yellow anthers (small pollen sacs attached to each stamen/stalk).

Viewed from the side, each spray or head of elderflower has a distinct shape, called an umbel i.e. the flower stalks all arise from a common, central point to  form a flat-topped flower cluster. Across the flat top, each umbel can measure anywhere from 5cm to 30cm (2 inches to 12 inches) in diameter.

Leaves:
The leaves of the Elder have a slightly serrated edge. On each twig you will find one terminal leaf along with 2 or 3 pairs of leaves growing directly opposite each other.

Scent:
In full bloom, elderflowers have a beautiful, sweet, summery scent… however, until you become familiar with this scent, it’s better to use the identifying features above.

Season:
Elder trees bloom for approximately 6 weeks every summer. Depending on the weather and a number of other factors, the elderflower season may run any time from May to July (in Ireland, the UK and elsewhere in the Northern Hemisphere).

Here on the East Coast of Ireland, elderflower season has varied by several weeks over the last few years.

2017 – Season began end of May

2016 – Season began early June

2015 – Season began early May

In other words, it’s important to keep watch for elderflowers from early May!

Note that in your first year foraging elderflower, you will have to keep an eye out for Elder trees… in the second and subsequent years, you can (hopefully!) return to the same spot to pick your elderflowers.

Picking Elderflower:
The best time to pick elderflower is on a warm, sunny day. This is when the blooms will be heavy with pollen (and it’s the pollen which gives elderflower its distinctive scent and taste.)

For this reason, it’s best NOT to pick elderflower on a windy or a wet day as the pollen will be blown/washed away.

Choose heads of elderflower which are in full bloom, very fragrant and have a beautiful white/cream colour.

Avoid sprays of flowers which are still partially in bud (early in the season) – see below.

Avoid also sprays of flowers which are starting to discolour or decay (late in the season) – see below.

Beware of picking elderflower growing very close to busy roads – the flowers can sometimes be tainted with traffic fumes. Beware also of picking low-hanging flowers, particularly in areas where dogs, foxes or other animals may relieve themselves!

Transport your elderflowers home reasonably soon after picking… our expeditions usually last somewhere between 1 and 3 hours in total. It’s not, for example, a good idea to pick elderflowers and then leave them to sweat in a hot car for several hours.  Instead bring your elderflowers home and either

  1. Use them immediately or
  2. Transfer the elderflower heads into plastic food bags, squeeze out as much air as possible from the bags, seal and stow immediately in the freezer. (my preference)

I have found that freezing elderflowers in this ways allows them to retain their taste and fragrance for at least 2 months.

Do not wash/rinse your elderflowers – this washes away the pollen and hence the taste and fragrance!

Equipment:
When we go elderflowering, we bring the following:

  • Small scissors – instead of twisting or breaking the elderflower heads, it’s often easier to quickly snip the elderflower with a small scissors.
  • Cloth bag – place your foraged elderflower heads into a cloth bag (or use a small basket or cardboard box). Do not use a plastic bag! Plastic can make the elderflower heads sweat and deteriorate on your journey home.
  • Umbrella with a hooked handle – we use this to gently pull branches of Elder towards us – the best elderflowers always seem to be just out of reach!

(We also tend to wear long trousers or jeans, as Elder trees are often surrounded by stinging nettles and thorny brambles.)

What is NOT Elderflower:
As well as knowing the identifying features above, it’s equally important to know what is NOT elderflower.

Many different plants can be confused with elderflower for example cow parsley, cowbane, pignut, hemlock, pyracantha, red osier dogwood, rowan and hawthorn. (Even Michelin-starred chefs have been known to mistakenly identify elderflower…)

not_elderflower2

The above picture is NOT elderflower. Note that each flower (red osier dogwood) has 4 pointed petals. (Elderflower has 5, rounded petals.)  The leaves have a smooth edge. (Elder trees have leaves with a slightly serrated edge.)

cow_parsley

The above picture is NOT elderflower. Note that these flowers (cow parsley) are growing on green stalks, directly from the ground. (Elderflower grows on branches of an Elder tree.) There are no leaves on the stalks. (Elderflower will be surrounded by leafy branches.)

IMPORTANT! Hemlock is a highly poisonous plant that grows on a green stalk (with purple blotches) directly from the ground, and looks very similar to the cow parsley pictured above. Do not confuse hemlock and elderflower!

not_elderflower3

The above picture is NOT elderflower. Note that the flowers (cowbane) do not have 5 rounded petals – instead the petals are somewhat ragged and lack the white stamens and yellow anthers of elderflower.

not-elderflower6

The above picture is NOT elderflower. Note that the flowers (hawthorn) are larger than elderflowers and have brown/black anthers. Contrast with the delicate white stamens and yellow anthers on elderflower.

rowan2

The above picture is NOT elderflower. Note that the flowers (rowan) are again larger than elderflowers and have brown/black anthers and an almost hairy appearance due to the number of stamen protruding from each flower. Contrast with the delicate white stamens and yellow anthers on elderflower.

Side-by-Side Comparisons

elderflower-v-cowparsley

In the picture above, I am holding a head of elderflower on the left beside a spray of cow parsley on the right. Again, note that cow parsley (and hemlock, pignut, cowbane and other similar plants) all grow on stalks, directly from the ground, rather than from a tree or bush. These plants also lack the surrounding leaves (with serrated edges) that you find with elderflower.

elderflower-v-hawthorn

In the picture above, note the elderflowers on the left with a hawthorn tree on the right. The hawthorn tree is thickly covered in profusions of white flowers. The Elder is not so thickly covered with flowers – instead the elderflower heads are sporadically dotted across the tree.

elder-trees-v-cow-parsley

Note the elderflowers growing on the two tall Elder trees in this photo. In the foreground, you can see cow parsley growing on stalks directly from the ground.

Other Considerations:

  • Although elderflower is highly identifiable as outlined above, only pick it (and any other wild foods) if you are absolutely confident that you have identified it correctly. If in doubt… leave it out!
  • Always leave more than you take… for example, pick a couple of elderflower heads from several different trees rather than stripping a single tree of all its blooms. This means that you will leave plenty of blooms for others (both people and animals) to enjoy.
  • Foraging elderflower for personal use on public land (e.g. parks) is generally acceptable in Ireland and is specifically allowed in England, Wales and Scotland.
  • On private lands, it’s good practice to ask permission in advance from the landowner to pick elderflower. Many householders are very happy to allow you to pick some elderflower from their gardens, particularly if you promise them a bottle or two of cordial in exchange!
  • Never pick elderflowers (or any other wild foods) in conservation areas or other protected sites.

2017 Comments
As of today (18 June 2017) there are still plenty of elderflowers in bloom in many parts of Ireland and the UK! Move fast though as you can never be certain how long these blooms will stick around.
