Sedum Spectabile Autumn Joy brings great colour to the border when so many other perennials have gone over.
The flowers when first opening in late Summer are a pale pink developing to a dusky rose red in Autumn.
In Spring and most of the Summer the succulent foliage is a silvery pale green and the developing flowers resemble a pale coloured broccoli, of which I am beginning to acquire a taste for, considering it has been getting rammed down my throat in recent months, apparently for my own good.
After the flowers have gone over most gardeners prefer to leave the flower stems in place and cut them back in late Winter when you will likely see the fresh protruding stems of the plant. I seem to remember that Autumn Joy is sterile, however the butterflies and hoverflies still seem to love it, I guess lack of sterility has nothing to do with the amount of nectar which the plant may have.
Position your plant in full sun otherwise it will get very leggy and will require support. The Chelsea chop, recommended by many for this plant will make it more compact and a little later in coming in to flower, for this reason I would not do it, being so far north, anything that makes a late flowering plant even later is perhaps not to be recommended. Sedums do not like to get water logged and prefer soil which is not too rich. Autumn Joy has been renamed – ‘Herbstfreude’ will I conform to this – probably not.
See how the colour of Autumn Joy has deepened by October 18th.

The Summer bedding plants and Begonia tubers were lifted from the borders a few weeks ago. The pots and hanging baskets were also emptied. Not my most favourite of jobs, but nevertheless satisfying when completed. The borders have been planted with annuals which will give a bit of colour now, and through the Winter, however its Spring when these ones will truly come to life. Tubs have also been planted with annuals and a good few with Spring flowering bulbs.
In the front garden we have planted — Forget me nots, Pansies and Polyanthus.
