Kerria Week


In English, some wag named Kerria plenifora "bachelor's buttons". Some people seem to have Kerria plenifora in full flower in Week 2011/17, but ours has only just been planted and is a little late. It is the blur of yellow at the bottom of the picture. The white behind it is Spiraea 'Arguta' and a John Downie apple tree. The main dash of yellow is of course Forsythia.

At left is a Berberis x stenophylla which seems to resent having been moved a few weeks ago: it is going smoky. Perhaps it is just the shock. It should be able to handle full sun. [It did: it survived.]

The grey trunk in the distance is the neighbour's walnut tree. The red is an azalea which I have not yet typed [and which later succumbed to sickness]. There is also a small white-pink rhododendron next to it, planted last week.


Here is the new growth of Pieris 'Red Mill' at the start of the week. Pieris flowers are not big eye-catchers: the new leaves in red are.

Kerria Week

Kerria comes into its glorious yellow bloom time in week 2009/17, but spring is galloping forward so fast that we are already seeing Syringa vulgaris in full flower too.

More data on the unusually rapid unfolding of spring in 2009: a German news agency report on 2009-04-23 (midway through week 2009/17) recalls how a sudden upward surge of temperatures back in Week 15 put a lot of blossoming into "fast forward" this year, meaning plants that are normally successive are blooming at the same time, with Malus and Syringa coming into bloom before the blossoms are off the early Prunus varieties including P. armeniaca. Some regions even report Taraxacum in full flower in Week 17, though I have yet to see this on my travels. The overdrive is "very, very unusual," said Gerhard Lux of the state-funded DWD German Weather Service at its office in Offenbach near Frankfurt. The development has surprised phenologists. In Week 14, the progress of spring in Germany had been about two weeks behind average but now spring's progress is ahead of average. With one week of April still to go, the average April temperature so far in Germany has been 4 degrees Celsius above the mean for the period 1961-1990, DWD data showed. That explains why apple trees have been coming into bloom before the early cherry blossoms have fallen. In the Rheingau, the wine-growing region west of Frankfurt on the bank of the Rhine, the difference from the mean has been 5 degrees. Rheingau Malus trees normally blossom 75 days after the flowers of Corylus appear, but this year the delay has been only 50 days, a DWD farm-weather expert said. (I have no data for Hamburg, but would estimate the discrepancy here as far less, since Corylus was not notably delayed in the north, and we are now only about half a week ahead of other years.) A DWD climatologist explained that the overdrive period began with an upsurge in temperatures in Week 15. A week later, many parts of Germany were experiencing daytime highs of 25 degrees, which is summer warmth in German terms, and the weather has stayed warm in Week 17 too. In addition there has been two thirds less rain than usual in April, DWD averages show. The drought has been pronounced in the north and east of the country, though Hamburg escaped the drought on April 22, with a good soaking greening up its gardens.

Kerria Week

This blog celebrates its first anniversary this week, having become a regular publication one year ago. Amelanchier rotundifolia is still looking gorgeous when week 2009/17 begins on Sunday but has practically vanished by the Wednesday as rain brings an end to three weeks of drought, and knocks the petals of many of the flowering Magnolia. The Tulipa have already peaked too. Rhododendron russatum is a touch more predictable, offering a fine covering of purplish blue as an offset to the neighbouring orchard full of apple blossoms, nodding white Narcissus, clouds of Forsythia and the delicious pink of a Prunus serrulata 'Kanzan'. This sort of scene illustrates the acme of what a succession gardener is trying to achieve: eyecatching colour standing out from a neutral background to create a delight for the eye. It's no use playing with mono-colour gardening schemes because you have to use a modest amount of bloom to achieve a big effect. So the succession garden is a piece of subtractive planning. You have to consciously tone down the visual fireworks of spring, save some dramatic effects for later and always keep that neutral background in mind. Such a garden not only needs a wide cast of "starring" plants to keep up the delivery of colour in the summer and autumn, but also those "chorus line" plants to provide a leaf-and-bark background to whatever plant currently has the starring role. It's also important to remember one of the emotional effects of succession: the sense of season. A good succession garden should impart the feeling that something went before (and has faded) and that the time has yet to come for other plants which still look dull.

Amelanchier Week

This is perhaps the week that the German poet and theologian Paul Gerhardt had in mind in Geh' Aus Mein Herz, his remarkable 1656 religious poem about spring, nowadays sung to a pretty air by August Harder.
All the nature imagery in the poem, such as the mention of the tulips and daffodils, the nest-building by the storks and the rising wheat, is connected with this point of the German spring, which is around the 17th week of the year in Zone 8. Some of this imagery reappears in later Christian poetry, such as Sydney Carter's Lord of the Dance: "Now the green blade riseth from the buried grain."
Gerhardt's mention of summertime in at least two places in the poem (I have not quoted all 33 stanzas here) is misleading. Germans consider Geh' Aus Mein Herz a Sommergesang, but it would be more accurate to call it a "spring song". Perhaps Gerhardt simply regarded spring as a phase within his wider concept of summer. At the time he wrote, the division of the climatic year into the four perfectly equal seasons, just like the celestial year, may not have been as strict as it is today. Or perhaps, since he was a very great writer, he simply took a little of the poetic licence due to him. His literary purpose is plain: the poem is not about rebirth as such (an Easter or spring theme) but about greening, so that the entire flowering season becomes a metaphor for the Christian's growth: "Laß mich bis zur letzten Reis an Leib und Seele grünen."

Geh’ aus mein Herz und suche Freud
In dieser schönen Sommerzeit
An deines Gottes Gaben
Schau an der schönen Gärtenzier
Und siehe wie sie mir und dir
Sich ausgeschmücket haben.

Die Bäume stehen voller Laub
Das Erdreich decket seinen Staub
Mit einem grünen Kleide
Narzissen und die Tulipan
Die ziehen sich viel schöner an
Als Salomonis Seide.

Die Lerche schwingt sich in die Luft
Das Täublein fliegt auf seiner Kluft
Und macht sich in die Wälder
Die hochbegabte Nachtigall
Ergötzt und füllt mit ihrem Schall
Berg Hügel Tal und Felder.

Die Glucke führt ihr Völklein aus
Der Storch baut und bewohnt sein Haus
Das Schwälblein speist die Jungen
Der schnelle Hirsch das leichte Reh
Ist froh und kommt aus seine Höh
In’s tiefe Gras gesprungen.

Die Bächlein rauschen in dem Sand
Und malen sich an ihrem Rand
Mit schattenreichen Myrten
Die Wiesen liegen hart dabei
Und klingen ganz vom Lustgeschrei
Der Schaf’ und ihrer Hirten.

Die unverdroßne Bienenschar
Fliegt hin und her, sucht hier und da
Ihr edle Honigspeise
Des süßen Weinstocks starker Saft
Bringt täglich neue Stärk’ und Kraft
In seinem schwachen Reise.

Der Weizen wächset mit Gewalt
Darüber jauchzet jung und alt
Und rühmt die große Güte
Des, der so überflüssig labt
Und mit so manchem Gut begabt
Das menschliche Gemüte.

Ich selber kann und mag nicht ruhn
Des großen Gottes großes Tun
Erweckt mir alle Sinnen
Ich singe mit, wenn alles singt
Und lasse was dem Höchsten klingt
Aus meinem Herzen rinnen.

The plants mentioned include:
  • Narzissen: genus Narcissus. Daffodils are clearly spring flowers: a daffodil is brown and withers by summertime.

  • Tulipan: genus Tulipa. The tulip flowers briefly at the start of spring. The bulbs can be dug up and relocated from about June, when the stalks dry up and begin to rot. Tulips were a modern novelty in Gerhardt's time, having just been popularized in western Europe. About 30 years before Gerhard wrote, the Tulip Mania had occurred during a lull in the Thirty Years War. Nowadays Germans call the genus Tulpen. Gerhardt's form of the name matches older English forms like tulipa and tulipant.

  • Myrten: Possibly Myrica gale, which mainly grows in acidic bogs in the milder parts of Germany. Adelung (1793) and Grimm indicate this plant was formerly called Deutsche Myrte: Wegen einiger Ähnlichkeit in der Gestalt der Blätter, wird auch der Porst, Myrica communis L. von einigen Myrte, Deutsche Myrte, Engl. Dutch Myrtle genannt (Adelung: Grammatisch-kritisches Wörterbuch der Hochdeutschen Mundart) (The specific name communis does not come from Linnaeus, who considered this the type species, but was evidently added by later botanists. Ultimately however the botanical name M. gale prevailed.) The plant's old English name was gagel, from which one modern name, sweet gale, derives. Bog myrtle is today known in German as Gagelstrauch or Porst. Michael Fischer offers an objection to this identification however. The choice of Myrte as a motif to describe a stream in springtime is largely prompted by a European artistic tradition where a different plant, Myrtus communis, figures as a feature of paradise-like landscapes. Myrtus is a frost-sensitive evergreen tree which does not grow alongside German streams, so we are left wondering whether Gerhard was guided here by his observations or by his literary upbringing. Those who favour sweet gale must concede that Myrica gale is usually too small (2 metres tall) to cast much of a shadow on a stream, so the adjective "schattenreich" indeed gives rise to a certain amount of doubt as to what Gerhardt meant.

  • Weinstock: genus Vinus, which Gerhard mentions here as greening (in spring), not fruiting (in the late summer).

  • Weizen: presumably Triticum aestivum, though I cannot say what other wheat species were grown in mid 17th century Germany. Gerhardt mentions the green shoots rising in the fields, not the summer stage of the plant's growth.
I did not see an exhibition about Gerhardt in March 2007 at the Nikolaikirche in Berlin, but saw a notice about it by Arno Widmann (no longer online, unfortunately). I would also like to thank Dr. Michael Fischer for his highly informed advice about Gerhardt's allusions to a locus amoenus. Fischer does not believe that the poem is descriptive of Germany at all.

Amelanchier Week

2008/17: This is the time when the wonderful pinkish white of the Amelanchier rotundifolia is the eye-catcher, and the first, purple azalea (R. russatum) next to our eastern neighbour is approaching its peak. The raspberry is fading a little, but the daffodils are still glorious. Hosta shoots are poking up, paeonia leaves are unfolding, the most advanced lily shoots are 30 cm above the ground, the roses have their first dark red leaves, and the Deutzia is in green leaf. Acer negundo has come into modest flower and the first leaf buds are emerging on Acer saccharinum. The yellow Mahonia flowers are at their best now.The Tulipa have shaken off their green cases and are showing their true colours. Taraxacum officinale is springing up as yellow flowers in the lawn, suddenly visible then vanishing again.
