Coronilla orientalis
The genus Coronilla contains Old World shrubs and herbs.
Coronilla species are used as food plants by the larvae of some Lepidoptera species including the case-bearers Coleophora coronillae (which feeds exclusively on Coronilla varia) and Coleophora vicinella.

Chamaecytisus hirsutus
Soin Chamaecytisus hirsutus (L.)
Le Chamaecytisus hirsutus (L.) Link a un développement bien droit, avec le temps, elle devient un arbre. Le Chamaecytisus hirsutus (L.) Link est de taille grand , et peut atteindre les 17 m de hauteur;en automne assume une coloration jaune . Ces plantes ne pas toujours vertes, donc perdent les feuilles durant certains mois de l'annèe. Ces plantes ont un développement érigé; an bas elles montrent généralement un tronc dépourvu, tandis-que en haut elles s'élargissent en formant la chevelure.
Températures Chamaecytisus hirsutus (L.)
Plante qui a besoin au moins de quelques heures par jour d'irradiation solaire. On conseille de cultiver Le Chamaecytisus hirsutus (L.) Link à l'extèrieur durant toute l'annèe, vu qu'elles ne craingnent pas le froid.Dans un climat particulièrement venteux nous conseillons d'assurer les jeunes arbres à des longs tuteurs solides, de façon d'éviter que le vent puisse déchausser les jeunes racines peu développées; il peut arriver que les exemplaires de peu d'années craignent le froid intense et le vent.
Irrigation Chamaecytisus hirsutus (L.)
Les arrosages sont pratiqués uniquement lorsque le terrain est bien sec depuis plusieurs jours, habituellement chaque 4-5 semaines peut être suffisant; si le climat serait particulièrement chaud il est possible d'intensifier légèrement les arrosages,en utilisant 1-2 sècs d'eau . Nous conseillons d'arroser uniquement les exemplaires jeunes, ou qui viennet d'être mis en demeure; les exemplaires adultes se contentent généralement des pluies.
Parasites Chamaecytisus hirsutus (L.)
L'engraissage des arbres se pratique au début du printemps ou en automne, en utilisant de l'humus ou du fumier mûr; on intervient en mélangeant deux seaux de fertilisant au terrain, auprès du tronc de l'arbre chaque 2-3 ans ou au moment de l'implantation.
Adversité Chamaecytisus hirsutus
Généralement dans cette période de l'année nous conseillons un traitement préventif avec un insecticide à ample action,et avec un fongicide systémique, de façon à prévenir l'attaque de la part des aphides et le développement de maladies de champignons.
Substrat Chamaecytisus hirsutus (L.)
Cultiver ces plantes dans un terrain souple et profond, très bien drainé.

Cercis siliquastrum
Cercis siliquastrum
Cercis siliquastrum
Cercis siliquastrum at Wisley can be found in the Arboretum, the Rock Garden, Model Garden and on Seven Acres. The Seven Acres specimen is easy to find, just beside the Lake.
Cercis
Genus of about 6 species of deciduous trees and shrubs found in woodland margins and on rocky hillsides, in the Mediterranean, E Asia and N America.
They have alternate heart-shaped leaves and have brightly coloured flowers in spring, followed by flattened pods.
Flowers are normally produced on the previous years growth, but may also be borne on wood that is several years old, either before or as the leaves unfold.
Larger species are excellent specimen plants; grow smaller ones in a shrub border or train against a wall.
The Greek name Kerkis for a European species (probably a poplar) was also applied to Cercis siliquastrum which, possibly through confusion between the name Judas and the place Judaea is now known as the tree on which Judas hanged himself.
Cercis siliquastrum
A handsome broadly spreading deciduous tree that gradually develops a rounded crown, producing clusters of pea-like pink flowers on the previous years wood, and on the main trunk.
A spreading and sometimes multi-stemmed tree with heart shaped blue-green leaves 10cm (4in) long, bronze when young turning yellow in autumn.
As with many legumes this species can fix nitrogen, and is noted for attracting wildlife. The plants are hermaphrodite and pollinated by bees.
The wood is very hard, has a beautiful grain, and is used for veneer as it polishes well.
Cultivars include C. siliquastrum f. albida (syn. 'Alba') which has white flowers, 'Rubra' and 'Bodnant' which have dark purple-pink flowers.
AGM
The RHS Floral B Committee awarded Cercis siliquastrum an Award of Garden Merit and described it as a: Bushy, deciduous small tree. Leaves to 10cm wide, broadly heart-shaped. Flowers rosy-pink, pea-shaped, in clusters on the older wood. Fruit a conspicuous flattened purplish pod to 12cm long.
Cultivation
Grow in fertile, deep, moist but well drained soil in full sun or dappled shade. It flowers best in a continental climate.
Plant in final position when young, as it resents root disturbance.
To prune, remove wayward or crossing shoots to maintain permanent, healthy framework in late winter or early spring.
The tree often does not flower well in Britain, especially if the previous summer was cool.
May suffer from canker, coral spot, Verticillium wilt, leafhoppers and scale insects. However, it is notably resistant to honey fungus.
Propagation
Sow seed in containers in a cold frame in autumn.
Root semi-ripe cuttings, or bud selected clones in summer.

Astragalus
Astragalus (As-trá-ga-lus) is a large genus of about 2,000 species of herbs and small shrubs, belonging to the legume family Fabaceae, subfamily Faboideae. The genus is native to temperate regions of the Northern Hemisphere. Common names include milk-vetch (most species) and goat's-thorn (A. gummifera, A. tragacanthus). Some pale-flowered vetches are similar in appearance, but vetches are more vine-like.

Anthyllis vulneraria
Anthyllis is a genus of plants in the family Fabaceae. This genus contains both herbaceous and shrubby species and is distributed in Europe, the Middle East and North Africa. The most widespread and familiar species is Kidney Vetch (A. vulneraria) which is a familiar grasslandNew Zealand. flower throughout the region and has also been introduced to
Anthyllis species are used as food plants by the larvae of some Lepidoptera species including the following case-bearers of the genus Coleophora: C. acanthyllidis, C. protecta (both feed exclusively on A. tragacanthoides), C. hermanniella (feeds exclusively on A. hermanniae), C. vestalella (feeds exclusively on A. cytisoides) and C. vulnerariae (feeds exclusively on A. vulneraria).
