Rosa Constance Spry

June 15, 2010

David Austin’s aim in breeding the race of so-called ‘English’ roses was to unite the robust growth habit and repeat flowering of the modern types with the flower shapes of the old. Unfortunately, Constance Spry, one of the first of this group, does not repeat flower. However, it is undoubtedly one of the most sumptuous of all roses, especially when – as in my garden – it is trained as a climber.

The pink flowers of Constance Spry are among the largest of any rose

I say ‘trained’. Loosely tied to a fence would be more accurate – the arching stems lend themselves to this relaxed treatment. At the moment, the buds are just starting to open into old-fashioned teacup-like flowers, a full 10cm across, clear pink and with one of the richest scents in the garden.

The fact that the display lasts a mere two weeks can be forgiven, considering the freedom with which the flowers are produced (it is rather like Albertine in that respect, also flowering now). Another downside is that the leaves are already showing signs of blackspot. At the moment, that’s not too serious a problem – but I may get busy with the secateurs once the flowers have faded.

Spots on cymbidium

October 5, 2009

I have now brought my cymbidium indoors for the winter, after summering it outside (in a shady spot). But I may put it outdoors again, if we have any mild, wet days.

Fluctuating late summer temperatures are supposed to stimulate flowering. We shall see – it isn’t until after Christmas (usually) that flowering stems appear.

Cymbidiums usually produce their flower spikes in the middle of winter

But while the leaves are wonderfully firm after being exposed to the elements, the young growth (brighter green than the old) is showing dark spotting. This is almost certainly not the dreaded mosaic virus (which can only enter plants via wounds) but merely a response to cold. As the leaves are evergreen, these blemishes will persist – not really anything to worry about, but they are unsightly, and these parts of the plant will be slightly more vulnerable to disease. I shall have to watch it.
