Dangling delight

Acer pectinatum ssp. laxiflora. This Acer flowered well and now we are reaping the benefit of the winged seed. The reddish pink wings envelope the seed, multiples are carried as a raceme from leaf axils. TheAcer pectinatum ssp. laxiflora colour darkening as the nights get longer and the temperature drops. Catch them on a day when the sun is shining behind them and the true beauty is appreciated. Acer pectinatum ssp. laxiflora

Originating in Sichuan, China, this deciduous tree was observed growing on open south facing mountainside covered with regenerating trees and shrubs.

Autumn colour

The deciduous foliage of Tripterygium regelii is yellowing gracefully. This ungainly climber reaches 5 metres in Japan from where seed was collected. In Amori Prefecture it was growing in mixed deciduousTripterygium regelii woodland on a south west facing slope at c. 900m.  

The sturdy leaves are attached to the flexible brown shoots by stalks showered in minute bristles; these continue to appear on the midrib at the reverse of the leaf. The white flower panicles have matured to display collections of three winged nuts. The papery shell that forms this three winged form turns a graceful red as the autumn progresses. Tripterygium regelii  

Visit the Garden, enjoy the fallen leaf mosaics and admire the colours. The clocks change at the end of the month so take advantage of the day length during the next two weeks.
