The ancient Chinese have cultivated Tree Peonies for over 1500 years. Prized specimens are and were grown for medicinal purposes as they contain glucocides and alkolides. The imperial palace gardens had many specimens that became quite valuable.
The tree peony was, for a time, the national flower of China and it is thought Chairman Mao sought to ban their growth as a decadent pastime. The root of P suffruicosa has been used in medicine for centuries.
Plants were transported to Japan in the 14th century. The Japanese bred tree peonies creating over 1200 hybrids some of which are still grown today.
The cult status of Japanese Tree peonies encouraged 18th century plant hunters to import tree peonies in to Europe, particularly France and England. These plant hunters like Veitch, Joseph Rock and Kelway started their own breeding programmes from some of the five wild species and other hybrids.
The Americans crossed P.lutea (above) and P. delavayi with Japanese hybrids to produce some of the vibrant colours now available. The flowers have a short but colourful life! The shrubs are far more long lived.
Tree peonies have long featured in oriental watercolour paintings. by Zou Yigui (1686–1772). Some of the varieties, like ‘Yao’s Yellow’ and ‘Wei’s Purple’ are depicted in a series of paintings mentioned in the Record of the Tree Peonies of Luoyang Ouyang xiu (1007-1072 CE).
Imagine the splendid sight when all the buds open.

Some trees are named to confuse. The Indian Bean Tree is not from India and it doesn’t grow beans. As a native of north America it is named for a North American native Indian tribe. The seeds are produced in long bean like pods.
Ornamental Japanese Maples are widely available for planting in your garden. The autumn colouring makes these trees spectacular when planted en mass in a woodland or Japanese garden setting.

My Rhododendrons were in full bloom when a late frost caught them quite badly. Winter has been wet and mild but if the USA is anything to go by hard frosts may still be on the way so look after your early flowering Rhododendrons.

Kiwi fruit known as the Chinese goodeberry grow on the woody vine Actinidia deliciosa and its hybrids. The vines should be grown on sturdy support structures as it crops more than the rather weak vines can support.This plant has a cold greenhouse for protection but they can be grown outdoors in a sheltered spot.
The larger Acer is not Japonica but Davidii. Under it’s branches is a more tender Acer palmatum Japonica var. dissectum ‘Inaba-shidare’ or the purple leaved Japanese maple.
The leaves of this Hydragea Aspera are one of its key features. As with other Aspera subspecies the branches and leaves are ‘strigose’ which botanically means ‘beset with appressed straight and stiff hairs’ that means rough and furry to me.
Mesclun is a name for a traditional melange of salad leaves. The name mesclun doesn’t feature in any of my gardening reference books before 1980 so old gardeners may not recognise the term.
Lilacs are members of the Syringia family and are named for the colour. There are deep lilacs verging on violet and light pinkish lilacs even some pretty floriferous white flowering Lilacs.
