About this Blog

This blog reflects our twin interests in walking and natural history, especially botany.



"Ich wandle unter Blumen

Und blühe selber mit ..."

Heinrich Heine





Walking is important to us as a way of being in direct touch with the environment, experiencing species and habitats in their ecological and historical context. By walking between different flower sites we experience the character of the general countryside, getting to know as much where flowers are not as where they are. Walking allows for the serendipitous - chance encounters with animals, meetings with local people, unexpected species - which enrich the experience.

We set up this blog to share a variety of mainly day-long walks centred on "iconic" flower sites and locations of rare plants, where these are publicly accessible. The accounts include descriptions of the routes taken, key plants seen, other wildlife encountered, and anything of general environmental or historical interest. All the walks allow time for looking around (some flowers need searching for), photography etc, and usually include a half-way stop for refreshment at some suitable establishment. The walks are seasonal, depending on the flowering/fruiting times of different species, although one cannot hit the peak time for all species seen on one walk, and the best timings will vary from year to year. Lengths vary but the walks may be anything up to 12 miles or more, so an early start is recommended.



A certain knowledge of our flora is assumed, but those less familiar should be able to identify most of the plants mentioned with the help of one of the good field guides - Blamey, Fitter and Fitter Wild Flowers of Britain & Ireland (A&C Black) or Francis Rose The Wild Flower Key (Warne) - although occasionally recourse may be needed to more technical tomes such as Clive Stace New Flora of the British Isles (Cambridge) or the specialist volumes published by BSBI (Botanical Society of the British Isles) on grasses, sedges, umbellifers etc.



While examining plants it is interesting to note the galls, leaf-mines and fungi (rusts etc) that are often specific to particular taxa. For galls we use Redfern and Shirley British Plant Galls, for leaf-mines http://www.ukflymines.co.uk/ (which also includes lepidopteran and other mines), and for fungi Ellis and Ellis Microfungi on Land Plants, although this is a technical tome rather than a field guide.

Berkshire: Blewbury Churchyard


19 February 2013                                                OS 174: Newbury & Wantage

Length: 20-30 minutes (churchyard only); or extend into 2 hour walk via Blewburton Hill.

The main point of this visit was to look for the 'Blewbury Tart' variety of snowdrop first discovered in St Michael's churchyard, Blewbury, by Alan Street in 1975.  It is a very distinctive double variety of the ordinary Galanthus nivalis with erect, not pendulous, "double" flowers, the outer white tepals narrow and inconspicuous compared to the proliferating distorted green inner tepals.  It has been propagated and is available from sellers of garden bulbs.

We parked at the car park by the Village Hall, Blewbury (in the NW corner of the village).  Immediately we spotted a large clump of mistletoe Viscum album on a tree planted at the edge of the car park, along with several other small growths.  The tree was unfamiliar, but from the distinctive bark and the dried remains of small erect fruit clusters we worked out it must be Manchurian Cherry Prunus maackii.  A new host for mistletoe for us.

 We walked down Church End towards St Michael's.  In the verge there were frequent snowdrops Galanthus nivalis, early crocus Crocus tommasinianus, and even an exceptionally early Dutch or yellow crocus C. x luteus.

 The lane leads to the entrance to the churchyard, where a display board announces that it is maintained as a conservation area.  It was certainly colourful with a variety of winter-flowering species.  An early queen buff-tailed bumble-bee Bombus terrestris was exploring this oasis of nectar and pollen.

These included primroses Primula vulgaris, winter aconite Eranthis hyemalis in perfect condition, stinking and Corsican hellebores Helleborus foetidus and argutifolius, early crocus, and pink and white forms of eastern sowbread Cyclamen coum with its kidney-shaped leaves easily confused with neighbouring lesser celandine Ficaria verna  leaves in the short turf but darker and more leathery.

 The greatest number of flowers, however, were snowdrops of several varieties.  Apart from Galanthus nivalis and its flore pleno version (the latter particularly near the church entrance), the most frequent were the striking large cultivars of nivalis, 'Atkinsii' (with 3cm long tepals) and 'Magnet' (with 2.5cm tepals), which dominated a patch to the NE of the church above a ditch.  There were also G. plicatus with its distinctively folded leaves and its hybrid with G. elwesii, which had the folded leaves of plicatus and the green mark at the base of the inner tepals of elwesii.  The 'Blewbury Tart' variety had apparently not survived after its first discovery, as Michael Crawley in his Flora of Berkshire says that it had been re-planted.  A diligent search today failed to locate any specimens, however, and we presume it has once again succumbed.

 On the south side of the church stood a massive old yew Taxus baccata with a hollow trunk easily large enough to contain a person standing.

 We returned to the entrance and continued east along the pedestrian-only Watts Lane, which gave us a chance to see some of the numerous streams that criss-cross this village, the result of springs that were presumably the reason for the siting of this community here in ancient times.  At one time there was a watercress industry as at Ewelme.  There are still many old cottages, including thatched.

 Some of the streams had been cleared of vegetation, but in others there was plenty of fool's watercress Apium nodiflorum.  Along the banks was much lesser celandine, including the first we had seen in flower this year.

We kept eastwards along Bessels Lea Road to the B-road of Bessels Way, across which the walk continued as a bridleway past a farm (small nettle Urtica urens here) and towards the extensive ancient earthworks of Blewburton Hill, which hill-settlement presumably pre-dated Blewbury in the marshy plains.  The path was wide and metalled between ploughed clay fields and remains of last year's rape crop.  As we approached the summit the path became grass and much muddier from horse traffic, but here there is a gate to a path just above the bridleway, from which you can mount to the top of Blewburton Hill (the wide view dominated by the steamy clouds erupting from Didcot Power Station) or continue on the path below the crest through rough chalk grassland.  Either way are splendid views of the red kites circling overhead or perched in the trees.

 At the east end of the hill it dips steeply down to the twin villages of Aston Upthorpe and Aston Tirrold.  We took the path that diverges slightly north from the bridleway, which brought us down past the church at Aston Upthorpe (little of botanical interest here, just a few snowdrops and primroses on the bank beside it).  Continuing along streets eastwards brought us directly into Aston Tirrold by a small War Memorial green where there were 'flore pleno' and 'Magnet' snowdrops.  Opposite is the Chequers Pub, now mainly a restaurant called The Sweet Olive.  This would normally provide a lunch opportunity, but we were unfortunate enough to arrive during the owners' annual holiday and had to depart empty-bellied.

We briefly continued to the east side of Aston Tirrold and its churchyard, but this again was devoid of botanical interest.

The high old brick wall along the lane south from this church has a wide shelf near the top, on which we found henbit dead-nettle Lamium amplexicaulum growing.  We then retraced our steps back to our starting point in Blewbury, where we found the dark brown winter form of the Green Shieldbug Palomena prasina basking in sun among ivy leaves.
