It’s getting cold now. Day length seems to be shortening rapidly. At least the sun is beginning to shine again, after a prolonged period of dull, wet weather. The summer perennials are putting on their final show, with asters taking centre of the proverbial stage…
There were some clumps of a tall, small blue flowered variety in the garden when we arrived. We added a couple of plants bought on a visit to the Picton nursery in Malvern, who have a national collection. Unfortunately I seem to have misplaced the labels, but I believe they’re Symphyotrichum novi-belgii varieties. They have bigger flowers, and a deeper colour.
What I’ve discovered, in just a few years, is that all of these not only spread like crazy, but also set seed very easily. Consequentially, these asters (which used to be called asters, but were subsequently re-named by those evil botanists as Symphyotrichum) have mounted a take-over plan. The resulting seedlings are showing variation from the parents. Most are watered down versions of the varieties we introduced (presumably being a mix of different parents). But we’ve also had some pure white ones come up. Some are unimpressive. But others, like this one, have bigger flowers and may prove to be worthy garden plants…
I’ve transplanted this clump from the inappropriate place it had set seed, to the back of a border.
These various asters do make a good show at a time when there isn’t that much else about, and even the small, washed out flowers of the worse specimens are proving popular with the bees. But they need judicious editing. I’m setting about limiting the spread by forking out the underground shoots that are spreading out in all directions. I’m trying to remove spent flowers as they go over, to limit seeding. And when the poorer specimens have finished flowering, I’ll dig them up and get rid of them.
Curiously the Symphyotrichum novae-angliae variety (‘Sapphire’) which has done well in previous years, hasn’t spread at all, and this year has been all but destroyed by molluscs. Aster x. frikartii ‘Monch’ has been slow to establish too, and is struggling to hold it’s own in the border. A shame, because it’s flowers are larger and more brilliant, and it flowers for longer.
Many plants struggle in our thin, dusty, sandy soil, but a few seem to love it so much they become uncontrollable. So far, I’ve discover three like this – the novi-belgii asters, lysimachia clethroides, and an un-identified variety of perennial sunflower which required an intensive programme of removal to eradicate it.
Other plants that are providing some colourful flowers in the garden at the moment include Rudbeckia fulgida var. sullivantii ‘Goldsturm’, here nestled among Stipa gigantea…
Helenium…
Hylotelephium (formally sedum – for the sake of ease, I now refer to them as Hylo’s). This variety is called ‘Xenox’…
Elsewhere Gaura – I beg your pardon Oenothera (have I said I don’t like botanists?) continues to flower as it sprawls all over the borders…
Anemone ‘Honorine Jobert’ has been flowering for a long time, and looks sparkling against the dark leaves of Actaea simplex ‘Brunette’ and the orange berries of the pyracantha…
Ceratostygma plumbaginoides seems to do well in our garden, keeping its head down for most of the year, and then producing these lovely, vivid blue flowers in late summer/early autumn…
We’re still getting a few roses, though the plants are looking a bit sickly. This is climbing Rosa ‘Wollerton Old Hall’, with a spider laying in wait for any unsuspecting insect visitors…
The woody salvias are still going (although the perennial Salvia guaranitica ‘Blue Ensign’, which dies back to nothing each year, hasn’t managed to flower yet). We have bright red ‘Royal Bumble’, and this, the dusky purple ‘Nachtvlinder’…
Colour is coming as much from fruits and leaves as from flowers now. This Euonymus alatus has been in for two years now This year it flowered, and has produced striking fruits. The leaves normally colour up a deep red…
We have a grape vine – a cutting from one growing at Dyffryn Gardens, where I used to be a volunteer – growing on our pergola. I can’t remember the variety. Being outside, any grapes it produces are unlikely to ripen, but they look nice…
And the vine leaves are giving good autumn tints…
According to the song by the Eighties band The Icicle Works, autumn is the finest time. Personally, I always find it difficult, because I love warmth and sun, and hate the cold. But even I can’t deny it is a time of great interest in the garden. I guess I’ll just have to pull on a big coat and enjoy the show.
