Yellow Rattle
69°F, 20°C, 10.25 a.m.: At the lower end of the walled garden at Nostell Priory there are two squares of wild flower meadow. Amongst the grasses, buttercups and dog daisies there are small drifts of yellow rattle, Rhinanthus minor, a plant that is semi-parasitic on the roots of grasses.
Despite a superficial resemblance, it isn’t related to yellow archangel, which I photographed in Stoneycliffe Woods at the beginning of the month: yellow archangel is a relative of the dead-nettles, one of the Lamiacea (mint) family, while yellow 
rattle is a member of the Scrophulariaceae (figwort) family, related to louseworts, cow-wheats, speedwells and foxglove.
Male Fern
A tall shuttlecock tuft of fronds of male fern, Dryopteris filix-mas, grows by the woodland path near the Menagerie. It has pale brown scales on its stems, which helps distinguish it from another tufted fern, the broad-buckler, which has a dark stripe running down the centre of each scale. The broad-buckler doesn’t form such a robust looking shuttlecock of fronds.
Curry Plant
The curry plant growing in the stone trough in the courtyard of the stable block at Nostell Priory is just about to come into flower. As its name suggests, it gives off a convincing aroma of curry if you brush against it or rub its leaves. If this is designed to deter insects, it isn’t working in the case of these black aphids that are sap-sucking along its stems.
Surplus sap excreted by the aphids is collected by ants, which have been observed to defend and sometimes to move the aphids, like farmers herding cattle. I spotted just one ant in the macro photographs that I took.
Spittle Bug
Also sap-sucking, a spittle bug. The nymph of the spittle bug produces a protective covering of ‘cuckoo spit’ by blowing bubbles in the surplus sap that it excretes.
Purple Loosestrife
The purple loosestrife is now at its best at the RSPB Old Moor reserve.
Two photographers in search of dragonflies apologise for trawling across my field of view, requesting that I don’t include them in the picture.
A shame, they would have added some scale. The loosestrife is shoulder high.
Jointed Rush
I think of rushes as being like the hard rush and soft rush; spiky and cylindrical, like a clump of green porcupine quills, but this is a rush too; jointed rush, Juncus articulatus, gets its name because the hollow stem is divided by internal ‘joints’.
It has clusters of star-shaped brown flowers which develop into egg-shaped fruits.
Yellow Rattle
This dry seedhead was growing on a grassy path edge. It reminds me of bluebell but we’re not in woodland – or old hedgerows – here and when I check it out in the book I’m able to confirm that it’s yellow rattle, Rhinanthus minor, which is semi-parasitic on the roots of grasses.
It is a member of the figwort family, Scrophulariaceae.
Each rounded capsule has a short beak at its tip. As it rattles in a breeze it distributes its winged seeds.
Bands of Blue and Green
I felt that I was getting a bit fussy as I painted the loosestrife so I went for a simpler approach with this nearby pond. With the quickest of pencil outlines I went straight on to the rapidly changing sky and its matching reflection, followed by bands of the lightest greens in each area to indicate distant trees, meadow, reedbed and reedbed reflections, plus the nearest willows.
With every bit of paper assigned a tone I could them add mid-tones of foliage and finally the darkest patches, adding a few of the brown branches of the willows.
Wedge of Meadow
IT’S EXPECTING a lot to wedge my wildflower meadow between the potato & onion bed and the bottom corner of the garden. I’ve still got to to dig out the chicory that has muscled out all the competition on the strip alongside the hedge, on the right of my photograph. I weeded this attractive but invasive wild flower out along the other two edges the triangle in the spring and resowed with a wildflower meadow seed mix which has sprouted so luxuriantly that I now need to trim it to create a perimeter path.
I’m pleased that in the central area the yellow rattle is flowering again this year. The theory is that it will keep the grasses in check because it is semi-parasitic on their roots but the grasses are thriving.
Hop Trefoil
THIS CLOVER-LIKE trefoil scrambles amongst grasses and taller herbs. It’s leaves are more elongated than clover. I’m guessing that it’s Hop Trefoil but there are a number of similar species, so I need to take a closer look. One of the advantages of having a patch of meadow at the end of the garden is that it is easy to do that.
Yellow Rattle hasn’t yet shown up in the section of the meadow that I sowed this spring but I can see 10 plants, mainly gone to seed, in a square yard of the established turf that I laid down. It’s a vital part of the wild flower mix as it is semi-parasitic on grasses, preventing them from dominating the meadow.
