Cornus Venus



Cornus 'Venus' blooms with the foliage but with such profusion you forget about the leaves.
Flowers are very large - 6 inches.
Venus Dogwood grows very vigorously as a dense tree branched low to ground with upright branches which form a rounded head wider than tall.
Heights of 5.48 meters and a spread of 6.55 meters have been reached in 20 years.

Cornus x ‘KN-30-8’ Venus® is an advanced generation interspecific hybrid involving germplasm of Cornus kousa and C. nuttallii.
Plants of this hybrid are distinguished by their exceptionally large, white floral bracts, superior winter hardiness, good tolerance of drought conditions, and high resistance to the incitants of Powdery Mildew and Dogwood Anthracnose.

Neuer Blumen-Hartriegel: Cornus 'Venus'
Eine neue Züchtung aus der Familie der Hartriegel macht derzeit von sich reden: Cornus 'Venus' ist eine Kreuzung aus Chinesischem (Cornus kousa chinensis) und Pazifischem Blumen-Hartriegel (Cornus nuttallii).

Eine echte Attraktion sind die riesigen, bis zu 13 Zentimeter großen, cremeweißen Blüten.
Sie öffnen sich genau zur richtigen Zeit, nämlich Ende Mai, wenn der Frühlingsblüten-Rausch vorbei ist und die Rosensaison noch nicht begonnen hat.
Die weiße Pracht besteht eigentlich nicht aus echten Blüten.
Es handelt sich um umgewandelte Laubblätter, sogenannte Hochblätter. Sie wirken wie Blütenblätter und umschließen die eher unauffälligen, halbkugeligen Blütenköpfchen.
Auch im Spätherbst (November und Dezember) ist der Blütenstrauch ein Blickfang: Große Früchte, die an Erdbeeren erinnern, und eine leuchtend orangerote Blattfärbung machen diese Pflanze auch nach der Blüte zu einer attraktiven Zierpflanze.
Den Winter übersteht 'Venus' im Gegensatz zu Cornus nuttallii mit Leichtigkeit und kann deshalb ohne Probleme im deutschen Klima überleben.
Pflanzen Sie Cornus 'Venus' unbedingt als freistehende Pflanze, um die Schönheit der Blüten zur Geltung zu bringen.
Sie sollte leicht schattig stehen, jedoch nicht direkt unter einem Baum.
Auf durchlässigen, humusreichen Böden wächst der neue Blumen-Hartriegel am besten, wobei Sie Staunässe vermeiden sollten.
Das Pflanzloch am besten in dreifacher Größe des Wurzelballens ausheben und viel Humus einarbeiten. Cornus 'Venus' wächst für einen Blumen-Hartriegel recht schnell: Drei bis vier Meter Höhe und zwei Meter Breite erreicht die Pflanze in wenigen Jahren mühelos. Schneiden Sie die langen Triebe gleich nach dem Abblühen Anfang Juni kräftig zurück.
Das fördert die Blütenbildung und hält die Pflanze kompakt. Tipp: Auch als Schnittblume eignet sich Cornus 'Venus'. Die abgeschnittenen Zweige bleiben in der Vase bis zu drei Wochen frisch.

Poem by Johann Wolfgang von Goethe

Dieses Baums Blatt, der von Osten
Meinem Garten anvertraut,
Gibt geheimen Sinn zu kosten,
Wie's den Wissenden erbaut.

Ist es ein lebendig Wesen,
Das sich in sich selbst getrennt?
Sind es zwei, die sich erlesen,
Dasz man sie als Eines kennt?

Solche Frage zu erwidern,
Fand ich wohl den rechten Sinn:
Fühlst du nicht an meinen Liedern,
Dasz ich Eins und doppelt bin?

Copy of the original of Goethe's poem with Ginkgo-leaves pasted on it by Goethe himself.



The Maidenhair Tree, Ginkgo biloba

The first time I laid eyes on a Maidenhair tree was a few years ago in Merano, Italy and I just fell in love.
It was Spring; the imposing, yet delicate, conical tree was covered in unblemished, bright green foliage.
The fan-shaped leaves grew from the branches each in a different direction, which in itself is unusual, and were fluttering in the wind like those of poplars.

Looking like large thorns, were spur shoots decorating the older stems and branches.

The name "Ginkgo" comes from Japanese word "ginkyo," or "silver apricot", which describes the appearance of the fruit and says nothing about its infamous noxious odor, while "biloba" refers to the double-lobed, fan-shaped leaves.

This tree is a survivor, and very tolerant of a variety of growth conditions.
The fossil record shows that the species has been exisiting for over 150 million years.
In fact, it was once only known as a fossil, until it was re-discovered in China in 1691.
Ginkgo biloba is hardy to zone 4.
This relatively slow grower eventually forms a very large shade tree,
maturing at a height of 25m and a width of 20m.
Beginning with a gawky, open-branched, conical structure, it tends to become irregular,
and pruning is important early on the the tree's life to prevent branching at poor angles,
criss-crossing main limbs and loss of central leader.
Make sure to have a tall ladder and a big saw!
If the Maidenhair tree is too large for your garden, you don't have to deprive yourself;
it makes an excellent bonsai specimen.
Cultivars that are widely available in the nursery trade include 'Autumn Gold',
appreciated for dependable golden-yellow fall color and pyramidal growth habit,
and 'Princeton Sentry' which has a good columnar habit.
Others that are emerging on the market include:'Mariken' - A dwarf?'
Pendula' - The weeping Maidenhair tree.
'Tubifolia' - With tubular leaves.


Ginkgo has long been used in Chinese medicine and its use is growing in the West. Extracts of the leaves are said to be antioxidant and to improve circulation and short-term memory. Extracts of the nuts are said to be antiseptic and to loosen coughs.

Northern Seat Oat grass - Chasmanthium latifolium

2007 addition to the garden





Chasmanthium latifolium - Plattährengras syn. Uniola latifolia


Kleines Gräser-Lexikon sehr schön gestaltet und hier zufinden:







Northern Sea Oats add delicate beauty to borders where its seed heads sway gently in the breeze.
Its seeds are a nourishing food source for wildlife.
Oat Grass is an excellent addition to habitat gardens.
Seed collection is very easy.
Wait for the seed clusters to turn brown and strip them from the plant.
Allow them to dry on a plate for a few days and either crumble or pick apart the seed heads to separate the seeds.
Allow the separated seeds to dry a few more days before packing.


General Culture:
Easily grown in average, medium to wet, well-drained soil in full sun to part shade.
Tolerant of poor soils, but prefers moist, fertile soils.
One of the more shade tolerant of the ornamental grasses, self-seeds and may become invasive.
Leaving foliage in place over winter adds interest to the landscape and helps protect crowns from the cold.
Cut back to the ground in early spring.
