It took some three days for the water to turn clear again after the thunderstorm.

2010 September 17 to 24

On the 17th of September there was another cloudburst which produced 33 liters per square meter in less than an hour. This was sufficient to fill the two ponds and this time also the water deposit of 2000 litres. This water came partly from the garden house roof which is connected to the upper pond via the old wine barrel and a long hose.





The semi-parasite Odontites luteus has started to flower massively in many parts of the zone. Another typical flowering plant this time of the year is the annual grass Setaria pumila.






Practically inexhaustible is Picris hieracioides, which has been flowering for months, seemingly immune to summer dryness and still going strong.


I had a hard time mowing some areas full of these yellow beauties but spared an area in front of the house.



Mown area around the house.

Odontites luteus parasiting apparently on Hieracium pillosella.

Odontites luteus is here probably parasiting on Thymus vulgaris.

Setaria pumila is here taking advantage of the higher humidity, caused by the adjacent car park with the compacted, less permeable soil.

Three new species were detected and identified. Ononis striata was detected in previous years but mistaken lazily for a second, less conspicuously flowering of Ononis natrix. But O. striata not only flowers much later than O. natrix, it grows also on clearly different places with more shade.


Really new is Thymelaea passerina, an annual member of a peculiar family of mostly shrubs. It is probably introduced in the zone thanks to the bulldozer which excavated the trench last year.






But for the orange berries, Solanum villosum is almost indistinguishable from Solanum nigra. It grows, together with its twin sister, on the artificial hill with the solar panels.




Ononis striata grows quite abundantly in the half shade of the middle terrace.

Ononis natrix, withered but still atractive on the higher terrace.
The yellow patches are from Odontites luteus.

Simple, grass-like flowers of Thymelaea passerina.

Four plants of Thymelaea passerina were detected along the track.

The vegetation on the walls of the different buildings is doing fine. The vines suffered somewhat from the summer drought but are recovering. It is still not certain if some climbing species like Hedera helix (Ivy) and Hydrangea petiolaris will be able to actually stick to the plaster.











Clematis montana (var. Rubens) doesn't have this problem as it uses the chop sticks fixed into the wall to wind its petioles around.

This Ivy is the same plant as the one in the picture below, but I guided it inside the greenhouse.
23 Sep 9:36
This Ivy was planted in the greenhouse to cover the inside walls.
Jasmine and chard on the left.
23 Sep 9:35
This Ivy is growing well but still doesn't show its sticking abilities.
With some Barbarea vulgaris flowers.
23 Sep 9:33

This Clematis montana has reached already the transparent fibre roof of the greenhouse.

The vegetation on the roof of the house has survived the summer and numerous seedlings can be found, many of them I suppose are from the annual Alyssum alyssoides, a plant that fits very well in the vegetation dominated by Sedum species.


A Sedum roof  is supposed to be less isolating than a  green roof with a thicker soil layer (>15cm) and grass vegetation, but it is practically without maintenance (no watering and no mowing) and aesthetically more pleasing.


The stalks of the Sedum vegetation stay erect and gracious. A grass vegetation would be much more flattened and shapeless by now.
17 Sep 8:55
The sun produces a nice effect on the transparent fruit remains of Alyssum alyssoides.

Late summer is one of the most photogenic periods of the year, with mist and humidity setting in but with still many surviving colours and structures.

Thumbs up, seems to be the prayer of this mantis.
