Lonicera crassifolia

A lovely little evergreen creeping (not climbing) honeysuckle for ground cover or rockery. Possibly too vigorous for a trough but not rampageous. Just to give you a sense of the scale, that's an ordinary winter heather there at the top.

Season of fruits and mellow mistfulness

I surprised myself this morning, strolling into town (to the dentist as it happens). It was wet and overcast and the leaves were really beginning to turn and fall, and I thought to myself what a relief it was that the summer was over. That's what surprised me. Normally I love the warm weather and tend to get a little depressed when it's over, but no, today I was positively buoyant.

The summer has been 'disappointing' they say, but then they say that every year. Normally I'd disagree but this year... What's it been? It's not been the rain - we've had something of a drought. Things have been looking quite sorry for themselves. Maybe it's been the sun. It's been dry, but it hasn't been bright, which is an unsatisfying state of affairs. This carried on until early October, by which time I was heartily sick of it. The cold and wet came as a welcome reprieve.

Actually I've known for a while I have a problem with August - memories of wet camping holidays as a child I expect. August is a con. It's not summer.  August is the overture to autumn (as February is the overture to spring). You can feel it in the air. May and June are summer. I noted this year that things started to go off soon after the solstice. You might have noticed if you've been keeping up with the Emma's Garden photoset on Flickr that there's a lot fewer pictures from July to September than for other times. There's just nothing photogenic going on (unless you're into macro when you can look at the flowers in isolation and ignore the total ho-humness of everything around them.)

So now I look around at the garden and am once again filled with energy. Finally I can do something. As you'll know by now I'm not a fan of the well ordered neat-and-tidy sort of garden and I don't cut things down until I have to, but there's been a few things I've been looking at since July and inwardly groaning. It's my first full year here and I'm still very much learning how to grow things on this soil (clay, not much sun - the total opposite to gardening on the chalk near Lewes.) Things really have taken off here, especially in what I call the sunny border (it's all relative.) The Diascia personata especially has formed a huge engulfing mass, obscuring several less vigorous plants that I hope will still be there when I come to cut the Diascia back (or remove most of it actually.) Salvia uliginosa, which I thought would stand up straight behind and amongst it has flopped over on top of it, and the Helianthus atrorubens, also included for the tall dark wiry stems I imagined would stand tall behind that, has also fallen forward over everything.  The problem is partly a red maple (bought as a standard tree some years back - it has never thrived), the fence behind and the path in front. Plants do not just passively fall over, they 'perceive' the path as an open space to grow into, and the tree and fence as shade and competition to grow away from. Hence they end up horizontal, getting trodden on. The mass of undergrowth was satisfying for a time - the Buddleia lindleyana held it's own well, the Eryngium giganteum elbowed its way up through the tangle, Gladiolus tristis shot up to 6ft high of so to get it's peculiar flowers into the light, like Diplodocus heads peering out of a thicket. But Rudbeckia maxima is under there somewhere, as are a couple of Dierama and two Decaisnea. I hope they'll recover. Kniphofia caulescens has definitely rotted off.

So anyway, perhaps you'll understand how, despite the fact that the Diascia and the Salvia are still blooming away, I'll be glad to get in there with the secateurs. The Diascia anyway I can honestly say I am thoroughly bored with. People always want to know about plants that just go on and on flowering all summer long, and if that's what you want I can heartily recommend it. You can have some of mine in fact (they're extremely easy from cuttings and totally hardy) but I'm sick of it. I like my season-long interest to come from the turn-over - things coming and going, changing places.

So that's one job. Whatever Diascia personata I keep will be further back, mixed in amongst everything else.

Then there's the huge Miscanthus in the middle of the border too. I can't wait for that to go over so I can have it out and do something better with that space. The maple will have to go too (it's had its chance) and the Lavatera Lilac Lady beside it. It's a good form - smaller that the commoner varieties and a nicer colour but not what I want now really. That'll leave a huge gap. I can't wait. Everything'll transpire a huge sigh of relief.

As for the rest of the garden - there's similar stories elsewhere. Mostly I'll leave the stems and old seed heads as long as I can - probably until January. I'll leave a stubble to discourage the dog from wandering about snapping off the new growths in spring. I'll make hazel 'bird-cages' for the Salvia and the Helianthus to grow through to support them through next summer. I've taken down the Bronze Fennel because I don't want too many of her offspring - lovely as she is.

People assume fallen leaves smother plants but except for small evergreens (lawns for example) that's rarely so, and the worms take them away and feed the soil in the process. People also like to cut things down as soon as possible after flowering - to get a second flush of flowers or make the plant put it's resources into the roots instead of the seed heads. I'm not sure either of these things make that much difference to most plants. I think it's more about neat and tidiness and I prefer the untidy textures and colours of autumn.

Which brings me back to my original point. When the dusty, listless scruffiness of August gave way to death's rich tapestry a couple of weeks back it was a release. Last 'summer' seemed interminable, but now, here we are, ready to move on again...

Persicaria virginiana and filiformis

Persicaria virginiana Compton's form
This American species is not that often offered, possibly because the flowers are quite small bright red filaments and appear in Autumn. A magnificent foliage plant though - as good as many of the tropical Calatheas and Marantas (prayer plants). The leaf surface has a real lustre - richly coloured and with an odd black chevron - I know not why.

A good solid perennial for any soil in sun or semi shade. Height up to 4ft and not at all invasive.
£8

Persicaria filiformis

Originally bought as P.virginiana filiformis. I recently discovered (researching the next plant) that despite superficial similarities with virginiana, this is in fact an Asian species. This is a more lightly built species up to only 2ft tall but with exquisite velvet lustrous lime green leaves, and again with that dark chevron.

The red filamentous inflorescences are produced earlier, in late summer/early autumn. It does seed about a little but in a good way. Very adaptable but best on moist soils

Hardy Impatiens

I keep on telling people that these things are hardy but they don't really believe me. The look on their face says 'Yes but not really', and I say, no, they've all survived outdoors in the ground both here and on our heavy soil at home, and they still don't really believe it, but I can promise you. There is in fact a narrow shady raised bed at the nursery only 6ins deep over the Mypex where three of them - arguta, uniflora and puberula are in danger of taking over. They even seem to do quite well in dry shade under shrubs. Almost too good to be true.
People are always wanting plants for shady places that flower on and on all summer. Well here they are. Come and get them...

Impatiens arguta, originally uploaded by peganum.

Impatiens arguta

The most reliable hardy species here in Sussex -  even in dry shade. A vigorous species with large tubular purple flowers on red stems. Ideal for any shady situation and flowering all summer. 

A large plant in the border at the nursery in late October. What's not to like?
1L pots ~ £8

Impatiens puberula

Another hardy purple flowered species, this time with soft green, somewhat fuzzy foliage. The flowers are more chubby with dark purple lips and a paler 'bag' behind, if you see what I mean.

Needs the same conditions as arguta but is more spreading as the stems root where they touch the ground.

£6

Impatiens stenantha

Another excellent hardy species for exactly the same conditions as the others. The foliage and stems have a distinct wine purple tint.

Caryopteris divaricata

The name Caryopteris is usually associated with a bunch of rather grey twiggy subshrubs grown mainly because they flower very late in the season (C. x clandonensis and the like). C.divaricata is very different - making a lush green upright bush and dying down completely in winter. The late flowering is the same but the flowers themselves are much more interesting as can be seen from the photo. Those of you who know the tropical Clerodendron (or Rotheca) myricoides (or ugandense) would be right in thinking they look suspiciously similar, with those long curling filaments and rounded purple blue petals. They are related.

Another well-known purveyor of rare plants describes the flowers as merely ‘harmless’ which I think is a bit unfair. They’re not huge or especially plentiful, but they are beautifully crafted and jolly pretty. The only down side is the foliage which has an odd odour (one customer calls it The OXO plant) so don't plant it too near the path unless you like that sort of thing. Also the stems are quite brittle so best planted amongst other things out of the wind.

Totally hardy and very adaptable. I will soon have a few of the pink flowered form available too.

Salix gracilistyla melanostachys

Salix gracilistyla melanostachys, originally uploaded by peganum.

A very wacky willow for you, this time grown for it's bituminous black catkins in early spring which sprout pale yellow anthers and have red highlights.
It's hard to get a good shot of this from a distance with any 'interference' in the background, but the black catkins, (see photo below) are striking. Potentially a large shrub but responds well to quite hard pruning immediately after flowering.

Senna hebecarpa

I'm not sure why the North American Sennas are not better known in the UK. I know two of them reasonably well - hebecarpa and marilandica (both sometimes included in Cassia.) The former seems to be the better of the two. They're big exotic looking plants but completely hardy given their distribution as far north as the Great Lakes.
The foliage is lush and the flowers give a good show in the latter part of the summer.

Ideal for prairie type plantings with other native Americans (so to speak) they grow well in moist rich soils in full sun but should tolerate some shade and drought.
