Hans, that's a glorious flower with elegant undulate floral form.  I assume it not hardy and is for a glasshouse or windowsill.

After all of the heat and drought, I've been watching the slow development of Gentiana clausa alba, unperturbed by the drought, surprising when this bottle gentian is found in moist locations and stream-sides. The foliage remained dark green, not showing any sign of scorching as so many of my plants have this season.  Last year I received a seedling plant from a friend who specializes in native North American plants, and I believe this rare white form was from seed collected in New Hampshire.  Fascinating too, is that the flower bracts appear well before the buds, making an intriguing and curious looking posy nested on top of the enlarged terminal leaves.  I like that the flowers are tinged green at the apex.  I include some links showing other colors forms, the more typical blues and purples.  My plant is 12" (30 cm) in flower.

September seems to be slow off the mark in the Northern Hem.
Here are some late (re)flowerers from my garden.

1) Fuchsia pumila - has been flowering non-stop for the last 3 months ... and it's not over yet ! 
2) Erigeron chrysopsidis 'Grand Ridge' - provides a second (or is it the third ?) flowering this season.
3) Rhododendron ferrugineum's flowering in the Spring was rather shy and it's trying to make up for it now ! 
4) Delosperma cooperi - always good for a splash of colour during Summer and early Autumn !
5) Helianthemum lunelatum has to be my favourite Helianthemum - it's practically never without flowers from May to October ! 
6) Oxalis 'Ione Hecker' surprised me with another flush of flowers - never had this before this late in the season 

[Ragged Robin]

You are lucky Luc with such lovely flowerings 

Erigeron chrysopsidis 'Grand Ridge' - provides a second (or is it the third ?) flowering this season.

so sweet nestled against the rock and I love the shadow too 

[Graham Catlow]

A nice splash of September colour Luc.
Do you protect your Delosperma cooperi over winter. I grew it in my rock garden for the first time last year and it did increadibly well, but lost it all over the winter.
I have seen it in more exposed gardens not far from here and it survived the winter.

The Delosperma often looks horrible after Winter Graham, but I cut it back and most of the time it recovers nicely and if a plant doesn't, I always find plenty of seedlings that take over !

[Lvandelft]

Luc, your Helianthemum lunulatum is gorgeous. I'm really envious

BTW I'm not a Rhodo specialist but I have seen so many years Rh. ferrugineum in the wild and your plant does not look like the natural form.
And the backside of the leaves are obiously not 'rusty'.
Must be a hybrid, beause I don't believe it's Rh. hirsutum too???

Thanks Luc,
I have been left with one seedling.

The Helianthemum is very high on my list of preferences as well Luit : such a good "behaviour" and so floriferous - I love it.

I got the Rhodo under that name 3 or 4 years ago from Portier nursery - the origin might even be Herman Geers, I don't know, but you are right, the leaves backsides' are not rusty....

Good luck with the one Graham ! 

[Maggi Young]

You've shown us more great plants, luc, obviously happy in your garden.
I agree with Luit- I don't think  the rhodo is pure ferugineum.... most likely one of the hybrids... perhaps one with the (invalid?) name of 'Intermedium' 
I think it could do with a tonic.....  some Miracid or Vitax Q4, something like that to green it up a bit.

[Luc Gilgemyn]

You're definitely right Maggi - it did suffer from the drought and the 3 to 4 weeks of heat we had in July...

[ArnoldT]

A herbaceous Clematis.

[Hans A.]

Actually there are very few flowering plants in the garden, most autumn flowering bulbs are still dormant, one exception is this Rhodophiala spec. (pratensis?), another flowering plant is Origanum dictamnus.

[Brian Ellis]

Not exactly rock garden plants, but I wandered round the garden and had a look to see what I could find as it was such a nice morning.  Much to my surprise there was far more in flower than I thought.

I like the Althea cannabina which can grow to two or three metres with a splattering of these delicate little flowers.
The Aristea ecklonii is in flower in the mornings only, a lovely blue, not many flowers at a time, but it does have a long flowering period - three weeks so far and another flower spike is just forming so I guess at least another three.
Aster x frikatii 'Monch' a sure sign that autumn is arriving.
Astrantia Gill Richardson group, an astonishingly dark flower, I saw a clump at Cally Gardens and had to have it!
Buddleja Lindleyana has been flowering it's heart out for a while and still some are to come.
In contrast is Crocosmia Okavango coming to the end of it's flowering soon.
One of my cyclamen hederifolium peeking out from under a Forsythia.
Daphne x transatlantica Eternal Fragrance is into its second major flush of flowers as is
Gladiolus flanaganii - I took some seeds off it yesterday!

[Brian Ellis]

I love Ipomea (once Mina) lobata and wish it would flower all year.
This unusual scabious is Miss Havisham, well named I think.
The phytolacca berries will soon be a feast for the birds, but this flower seemed to split in two.
Roscoea purpurea Peacock has been flowering for ages too.
I saw this Salvia at Old Wollerton Hall, it was wrongly labelled but we think it is Salvia Splendens 'Helen Dillon' whatever it is the colour is sumptious.
Scilla autumnalis is flowering in the snowdrop and fern bed.
This is my first Sternbergia which came into flower yesterday and I am pleased to see more buds too.
A new plant in the garden is Succisella inflexa 'Frosted Pearls', a delightful airy plant for half shade with tiny globular flowers, the second picture shows its size.
One for David, Tigridia pavonia, I don't know where this has come from so it must be a seedling
