Rosy garlic

The words ‘rosy’ and ‘garlic’ don’t seem to sit well together, the former associated with the sweet aromas that have inspired perfume makers for centuries, the latter with a pungent smell you either love or hate to cook with and/or eat. Here, though, the word ‘rosy’ relates to the colour of the plant’s flowers rather than its smell and, for me, this is a very attractive flower, particularly when the plants are found growing in good numbers as they were in an area of the Broadcroft Quarry Butterfly Reserve on the Isle of Portland.

As you may have worked out, this plant is a member of the Allium family that includes edible plants like garlic, the various species of onion, leeks and chives, as well as ornamental plants like Three-cornered leek, Field garlic and Star-of-Persia.

Rosy garlic (Allium roseum) is a Mediterranean species, not native to the UK, and is often seen in gardens, from which it has escaped and naturalised in areas of waste ground, mostly in southern Britain, particularly in coastal locations.

Magenta gladioli

During last month’s visits to the Isle of Portland, as I clambered around the former quarries, wandered the wildflower meadows and walked the public footpaths, I noticed the most beautiful magenta-flowered Gladioli growing randomly everywhere.

At first I thought they were garden escapes – and some of them certainly could have been – but, since my return, and having done some internet research, I can’t help but wonder whether these are the same variety Gladiolus communis subsp. byzantinus that has become naturalised on the Isles of Scilly. The vibrant magenta flowers certainly look to be the same colour.

According to the Seasonal Wildflowers website, this species – known locally as Whistling Jacks – is a relic of the Scilly bulb fields and grows throughout the Scillies, as well as having spread into parts of south-west England, and south and east Anglia. To me, it was almost as if Dame Edna had visited Portland and tossed the bulbs of her favourite gladdies everywhere she went.

Burnet rose

The Burnet rose (Rosa spinosissima, formerly Rosa pimpinellifolia) used to grow in my local area but hasn’t been recorded here since 2017 (I don’t know why – perhaps changing use of the environment where it used to grow), so it was good to see a lot of it in flower on the Isle of Portland.

This shrub usually grows low to the ground, forming clumps, sometimes with creeping suckering branches that form new plants. It’s most confined to dry sandy seaside areas and, if growing inland, favours calcareous locations.

My Flora Britannica says its pretty flowers have ‘the sweetest smell of any native rose – a mixture of honey and jasmine’; sadly I didn’t get down low enough to give them a sniff! It’s on the list for my next visit.

Horseshoe vetch

As it’s restricted to those areas in southern England where there is chalk and limestone, I hadn’t seen Horseshoe vetch (Hippocrepis comosa) until my recent visit to the Isle of Portland, or perhaps I should say that I hadn’t recognised it. The plant was, no doubt, growing all around me, especially when I explored the former quarries, but I hadn’t looked at it closely enough to realise it was different from the Bird’s-foot trefoil that it superficially resembles.

Both are members of the pea family, so the individual flowers are similar but the 5 to 12 individual flowers of Horseshoe vetch grow together in whorls, a structure that helps to identify them. I wondered whether this shape was the reason for their common name, but, in Flora Britannica, Richard Mabey notes that each flower develops into a pod ‘which breaks up into a number of horseshoe-shaped segments’.

As I noted in yesterday’s blog post, Horseshoe vetch is the larval plant for the Adonis blue butterfly (Polyommatus bellargus), which is why the populations of that butterfly are restricted to where the plant grows. The leaves of Horseshoe vetch are also used as a food plant by the larvae of the Chalkhill blue and Dingy Skipper butterflies, though the latter species uses several other plant species, meaning its distribution is not as restricted as the Adonis and Chalkhill blues.

Sainfoin

I had never seen this lovely plant before I spotted it at Broadcroft Butterfly Reserve on the Isle of Portland last Monday. This is Sainfoin (Onobrychis viciifolia).

As it was growing near some houses, I wondered, initially, if it was simply a garden escape. This proved to be partly true; according to Richard Mabey, writing in Flora Britannica, this erect form of Sainfoin was ‘introduced as a fodder plant from the continent in the middle of the seventeenth century’, and has since become widely naturalised. There is a native form which Mabey describes as ‘more or less prostrate, has deeper pink flowers and is native in grassland and bare ground on the southern chalk-hills’.

Though the Portland plants were the first sightings I remember, I’ve since checked the local biodiversity database and discovered there is a local site, a short train journey west along the south Wales coast, where I should be able to find them growing. As that is a location I haven’t been to for a while but which has other nice flora and fauna to be seen, I’m resolved to visit in the next few weeks to see if I can find Sainfoin, amongst other things.

As you can probably imagine, the shape of this plant’s flowers makes it noticeable, and provides the inspiration for the 90-plus vernacular names it has been known by over the centuries and from different locations around Britain (per Flora Britannica).

This is Arum maculatum, a plant most commonly known as Lords-and-ladies, a name that Flora Britannica says is ‘probably a Victorian invention, coined as a polite alternative to this great catalogue of vulgarities’. Those vulgarities include Cuckoo-pint (where ‘pint’, rhymes with mint, is short for pintle, slang for penis), Dog’s cock (a name from Wiltshire), Priest’s pilly (from Westmorland), and Willy lily (from the first Elizabethan era), amongst many others.

Fortunately, not all Arum maculatum‘s common names are focused on its flowers’ shape. In Flora Britannica, Richard Mabey also lists this, amongst others: ‘Starchwort, for example, recalls the era when the dried and ground-up tubers were used as a substitute for starch in laundries’. While you might not favour some this plant’s more ribald names, I do like the fact that the names show that people have taken the time to notice this plant (which people rarely do in today’s busy world) and to look at it closely enough to have imagined names for it.

All the yellows

The splendid sight of road verges gleaming with the brilliant yellow of blooming Dandelions is fast becoming just a wonderful memory as the council tractors and strimmers once again destroy any wildflowers they see in the name of ‘neat’ and ‘tidy’, and this despite the loss of some devastating percentage (50%?) of our insect populations in the last couple of decades. I grabbed some photos before everything started to disappear …

Alexanders: in places like the coastal path the only plant in flower so currently feeding a lot of small insects.

Broom: this might survive as it was in a park surrounded by Brambles.

Cowslips: in a country park so surviving, and looking very lush.

Creeping buttercup: gone.

Dandelion and Lesser celandine: prime targets for destruction.

Gorse: these tend to survive until the flail gets used.

Marsh marigold: a small survivor from a more numerous population, where a volunteer group decided they would build a dead hedge. Make it make sense!

Meadow buttercup: gone.

Primrose: these tend to survive while they’re flowering, then it’s off with their heads!

Sea radish: on the Barrage so not strimmed but the many dogs like to pee on them.

M is for mite

When preparing this series of countdown blog posts, I revisited the two locations where I found Grape mites (Galls on grapevines, 26 July) earlier this year, hoping to take a new photo to accompany this post. Unfortunately, I’d left it too late, as the grape vines were both bare, their leaves dead and already dropped off or blown from their branches on to the ground below. My find of this miniscule mite was one of my ‘first for Wales’ sightings in 2025 and I’m quite surprised to note that no other sightings have yet been recorded though, on checking iRecord, sightings do look quite sparse across Britain so far. I’ve already made a diary note to check for the mites (Colomerus vitis) again next year, and will be on the lookout for their telltale signs in other locations.

Aphid: Eriosoma lanigerum

When I set out on my walk last Saturday, I wasn’t intentionally targeting aphids but up they popped. At this first location I wasn’t completely certain that what I saw was caused by aphids but, as soon as I poked one of the fuzzy white lumps on this Firethorn (Pyracantha species) and my finger came away stained red, I knew I’d just inadvertently squashed an aphid (this has happened to me before when I grabbed a willow branch without noticing the aphids perched on it).

After a little research when I got home, it quickly became apparent that these were Eriosoma lanigerum, also known as Woolly apple aphids and American blight. The sap-sucking feeding of Eriosoma lanigerum causes deformation and swellings on the branches, trunks and roots of their host plants, as you can see from the lumpy growths on the branches of this Firethorn bush.

The white ‘wooliness’ is a wax substance the aphids produce in specialised glands and excrete as filaments from various parts of their bodies. The Influential Points website, which is an excellent resource for information about aphids, summarises the various reasons scientists have reached for this wax secretion:

Smith suggests that the primary role of the secreted wax is to prevent the aphids becoming contaminated by their own honeydew … and that of other members of the colony…. Other secondary roles of wax may include individual microclimate isolation, protection from fungi, parasites and predators plus waterproofing and frost protection.

Though their primary plant hosts are Pyracantha and Cotoneaster species, as the Woolly apple aphid name suggests, their secondary host is Apple and, on the various species of Apple trees, they are considered a major pest, often having a severe economic impact on Apple crops. If you’re interested in reading more about this, the Influential Points website has a long list of various scientific research papers from around the globe on the subject of these aphids, their reproduction habits, their seasonal movements, their genetics and population dynamics, as well as ways to control their infestations.
