My peppers are more than ready for potting on but I wanted to draw this Sun Spurge, Euphorbia helioscopia, now going to seed, before I do that. I took the soil for the peppers from the greenhouse, so it’s not surprising that this sprouted. Spurge ‘bribes’ ants to disperse its seed by tempting them with oil-rich attachments – elaiosomes – which the ants or their larvae eat before discarding the seed.
Like all euphorbias, as a deterrent to herbivores, the Sun Spurge has milky, latex sap that can cause irritation.
Even at the lowest magnification of 10x, you can see the cells in this chickweed leaf, which is just one centimetre from base to tip.
Zooming in to 60x you can see how the cells line up to make structures, along the vein and the edge of the leaf.
At 200x there’s isn’t much depth of field but it looks to me as if there’s a single line of cells forming a tube along the edge of the leaf.
These were taken on a Traveler USB microscope, which I bought in 2009 at Aldi’s. The software that came with it is long out of date, so it’s taken a bit of ingenuity by my computer expert friend Martin to find a workaround to get it working on my iMac, via a virtual Windows 10 installation.
Breakfast time: A female squirrel tries several times to climb the bird feeder pole but soon works out that she’s not going to get beyond the baffle. She climbs one of the cordon apple trees to assess the possibilities then climbs onto the hawthorn hedge and leaps across.
She’d make short work of our plastic bird feeders so I’ve relocated the pole a few feet further from the hedge, making sure that it’s not too close to the clothes prop holding up the washing line, a route that we’ve seen squirrels use to get to the feeders in the past.
Afternoon: A few honey bee-sized bees are continually visiting the blossoms of our Howgate Wonder double-cordon apple, sometimes chased off by a second bee or by a small, dark, cigar-shaped hoverfly.
The blossom has now gone from our single cordon Golden Spire and the apples are just beginning to form.
The daisies are hardly bothering to open up on such a cool dull morning but at least I don’t get a spot of rain until the end of my brief sketching session as Barbara and her brother John make their three-circuit – one mile – exercise walk around the park. A man, accompanied by his young son on a bike, has set himself the target of four miles: twelve times around Illingworth Park.
It rains properly in the afternoon, which our garden really needs after such a dry April. Hopefully we’ll now get a bit of warmth and things will burst into life.

Well that’s all the persuasion that I need, it’s got to be worth a try, although we might need a mown path across our back lawn to get to the veg beds and to hang out the washing.
I am of course a bit biased and I even think of garden weeds as wild flowers, however troublesome, so I’m not the one to judge when it comes to a dilemma between tidy management and wild & free.
Spray or Strim?
“What do you think of the change from strimming to using herbicides?” I ask a couple from the allotments alongside the park.
The man with the barrow isn’t convinced: “They’ve gone along the fence, but we’ve got bindweed down there, you think that was what needed doing.”
“We used to grow a blackberry along the fence,” adds the woman, “so people could pick the berries on the other side, but they said that we’d be liable if anyone was ill, so they’ve taken it out.”
Foothpath to the park and allotment sfence.
At first when I saw rings of dead grass around posts and litter bins, I blamed the local dogs, but it’s the result of the council making the change to spraying as an alternative to the expensive business of strimming around obstacles – which can be damaging to young trees.
I know how long it takes me to edge the lawn and to try and stop the chicory in our little meadow area taking over the paths and veg beds in the immediate vicinty, so I can imagine the scale of the problem of keeping things tidy over the whole Metropolitan District.
Plantlife is celebrating the way Wakefield and eight other councils are leading the way in better managing their road verges for wildlife, so I’m sure that the strimming versus herbicides dilemma has been carefully thought out, but however environmentally friendly the herbicide is that they’re using, there’s a lot of it being applied and inevitably there must be some impact on biodiversity.
A Red deadnettle, Lamium purpureum, has sprung up in a pot of soil taken from the greenhouse, growing more luxuriantly than the sweet peppers that I’d sown. It’s one of the first garden weeds to emerge at the start of the season.
A greenbottle settled on my sketchbook as I drew the first of the kingcups at the edge of the pond. Its blue-green metallic armour wouldn’t be out of place on a CGI robot but the it makes a living in the down-to-earth business of recycling: its maggot stage feeds on carrion.
The adult will also feast on carrion but is also attracted to flowers . . . and dung.
My macro photograph of a kingcup flower shows a cluster of stamens. The carpel, the female part of the plant, is almost hidden amongst them at the centre. The female carpels standing in the centre appear to be slightly notched on top, rather than rounded like the stamens and they’re very slightly greener.
So far this month, there’s been an air frost somewhere in the UK every night. It’s also been one of the driest Aprils on record, so it’s not surprising that, compared with last year, things are a bit behind. For instance, the kingcups by our pond have only just put out their first flowers today.
Harlow Carr RHS Gardens was originally the trial grounds for the Northern Horticultural Society, who chose a site on the edge of the Dales to ensure that any plant that could survive here would do well anywhere in the in the North.
Harlow Carr is the furthest that we’ve travelled since mid-autumn. We feel that it’s time for us to get out to different places again.
The yellow hooded spadix flower heads of skunk cabbage are bursting into life on the banks of the beck that flows through the gardens.
As we continue under high pressure, it’s been cold – sometimes down to below freezing on a night – and very dry. That hasn’t been a problem for the spurge, growing in my wild flower patch at the bottom of the garden. I guess that the milky, corrosive sap must work well as an anti-freeze and is perhaps one of the reasons that spurges do well in dry habitats, for instance in the dry, sometimes dusty, soil in the raised bed in our greenhouse.
It isn’t the most popular of plants with pollinators: during the hour or so that I’m drawing I notice only two insect visitors, both small flies, one a species of hoverfly. The small bumble bee in my sketch was working its way around the flowerhead of a dandelion.
We’re on coal measures rocks, so mainly shales and sandstones, which usually weather into slightly acid soils.
The foxglove is typical of dry acid soils and it self-seeds and thrives amongst our flower borders and veg beds so, as a change from trying to establish a patch of traditional English meadow on my wild flower patch, I’m going with the flow and planting out the foxglove seedlings transplanted from where they’ve sprung up to create a woodland edge habitat.
Flowers by Skelton Lakes motorway services, near Leeds. The chamomile and sowthistle may officially be weeds but they work well alongside the prairie-style planting. The gorse at the edge of the woodland is full bloom.
There’s still some mid-autumn colour in our flower but it’s not quite as punchy as my photographs suggest: today I’ve had the Art Filter on my Olympus E-M10 II set to Pop Art. All taken with the macro lens. I’m especially pleased with the detail on fly; as it was quite a cool day, the fly allowed me to push the lens towards it without buzzing off.
