Yes, you did read it right. The nursery is for sale! Some major life changes dictate that the time has come for me to move on to pastures new.
Ongoing health issues mean that I find it ever more difficult to devote sufficient time to maintaining a large collection of plants and this situation will only deteriorate as I get older. In addition to this I am also in the process of emigrating.
So, if you've ever considered turning your hobby into a business, there is an established nursery ready and waiting. Please contact me if you have a serious interest.

We headed into the forest on the 25th of July, visiting three bogs. After a month of dry weather, there had been 48Hrs of continuous rain preceeding our visit. The day proved to be cool, overcast and breezy. Less than ideal conditions for photographing very small subjects.
Stephen is familar with the forest over a number of years and knew where to look. The first bog was in fact the same as one of those visited the previous year. This time however we found more plants and I located an Adder (Vipera berus) by the simple method of very nearly stepping on it!
These are the Drosera images from the first and third bogs:
Typical habitat of the areas visited.
Growing largely submerged, perhaps the largest D. rotundifolia I have seen.
D. rotundifolia growing on a decomposing log.
Often mistaken for one another, seen side-by-side the differences between D. intermedia (left) and D. anglica (right) are very obvious.
D. x obovata
D. x obovata
We had been searching the first bog for some time when Nina made the first significant find by spotting a flower scape rising above the grasses.
Two very healthy Dionaea muscipula growing wild in Southern England!
Shortly thereafter Stephen located the diminutive Pinguicula lusitanica.
The second bog did not reveal any further plants of interest, but was home to a very fine spider living in a large funnel-web. I spent a long time trying to get a decent shot of the creature with its prey item. Several others were later found in the third bog. Subsequently identified as the funnel weaver Agelena labyrinthica.
The last bog was very wet indeed and Susan found our final prize of the day, the tiny and bright yellow flowers of Utricularia minor. Very difficult to photograph, I shot frame after frame in the hope of getting a few images in focus.

In terms of numbers and variety of plants found, I don't think that we could have had a more successful field-trip in the forest. The company was good too!
All in all, 'A Grand Day Out'.

FIRST TIME AVAILABLE!!!
VERY LIMITED NUMBER AVAILABLE!
A very large form of S. alata, featuring strong, bulbous and highly pubescent pitchers that will reach at least 107cm in height. In addition to fine pitchers, the plant has a very large and unusual flower. The under surface of the umbrella-pistil is covered in wavy outgrowths and prominences. The feature is consistent though the degree of deformation is variable from year to year. The flower is fertile and if pollinated yields large numbers of viable seed.

The Venus Flytrap Dionaea muscipula Counts Prey-Induced Action Potentials to Induce Sodium Uptake
- •Carnivorous Dionaea muscipula captures and processes nutrient- and sodium-rich prey
- •Via mechano-sensor stimulation, an animal meal is recognized, captured, and processed
- •Mechano-electrical waves induce JA signaling pathways that trigger prey digestion
- •Number of stimulations controls the production of digesting enzymes and uptake modules
Carnivorous plants, such as the Venus flytrap (Dionaea muscipula), depend on an animal diet when grown in nutrient-poor soils. When an insect visits the trap and tilts the mechanosensors on the inner surface, action potentials (APs) are fired. After a moving object elicits two APs, the trap snaps shut, encaging the victim. Panicking preys repeatedly touch the trigger hairs over the subsequent hours, leading to a hermetically closed trap, which via the gland-based endocrine system is flooded by a prey-decomposing acidic enzyme cocktail. Here, we asked the question as to how many times trigger hairs have to be stimulated (e.g., now many APs are required) for the flytrap to recognize an encaged object as potential food, thus making it worthwhile activating the glands. By applying a series of trigger-hair stimulations, we found that the touch hormone jasmonic acid (JA) signaling pathway is activated after the second stimulus, while more than three APs are required to trigger an expression of genes encoding prey-degrading hydrolases, and that this expression is proportional to the number of mechanical stimulations. A decomposing animal contains a sodium load, and we have found that these sodium ions enter the capture organ via glands. We identified a flytrap sodium channel DmHKT1 as responsible for this sodium acquisition, with the number of transcripts expressed being dependent on the number of mechano-electric stimulations. Hence, the number of APs a victim triggers while trying to break out of the trap identifies the moving prey as a struggling Na+-rich animal and nutrition for the plant.

sadly posting in special fora has become out of fashion and as a matter of fact this place has also gone asleep. Except of Aidan posting news from the nursery and science. So, one may wonder why I start a new thread. Perhaps I can draw a few buddies from the woodwork with this thread who still know me from the better times....
Unfortunately I don´t have a good enough digital camera for plant macro photography anymore. The Panasonic TZ 31 I used before is defective as the aperture cannot be regulated anymore. Of course this happened shortly after warranty had expired.
My stepfather gave me a smaller camera which he originally obtained for my mother and her 'snapshotting'! However the simpler camera´s still too complicated for my mother... Frauen und Technik!
So, we cannot expect much from this camera! It hasn´t even a setting for macro photography!
But I thought my first flower of a seed grown Drosera cistiflora is worth making and showing some pics.
What a surprise: A WHITE flower! I have expected a pink one as I have grown these plants as D. cistiflora 'Moedverloor' all the time. The Moedverloor location form should have pink flowers. Unless there really is a white flowering form at this location. But it could also be I mixed up the labels.
I had three seed packs of D. cistiflora: 'Nieuwoudtville', 'white flower' (Hermanus) and 'Moedverloor'. Tragically almost all seedlings died during their first six weeks in life! I was able to rescue only four seedlings. Those were in the pot with the "Moedverloor" label.
The flower has a nice size indeed!
All plants in one pot. First summer rest with the thin storage roots was critical. I lost one of the plants. But this season they are four specimens again. I will have a second flower as you can see.
The plants - still not mature of course - are three years old now.
The leaves are quite narrow at this young age.
For comparison: This is how the seedlings looked in 2014 (their second season).
These images have been gone lost due to a server crash in 2014 I guess.
And this is one of Aidan´s favourites or at least has been.... ^^
This chap is believing 'he' is a tree! ^^
Drosera hilaris' crown.
This is also a seed grown plant. The only grain that germinated at all. *phew*
The plant made a short summer rest in 2015. It didn´t die overground totally, it only produced extremely short leaves incapable of trapping prey. The flowers in spring were splendid. Too bad I had no camera at that time!
I apologise for not offering you more professional photos. But actually I have given up in photographing awhile ago.
Thank you for your attention!

As many of you will be aware, the nursery was offered for sale late last year. I am pleased to announce that the business has now changed hands and the new owner is James Ellis. James has been kept very busy in recent weeks getting everything organised and moving the nursery in its entirety to a new home on the south coast.
James who is both younger and fitter than I am has always wanted to run his own nursery and he has now been able to realise that dream. I have every confidence that James will move the nursery on to bigger and better things and I trust that everyone will join me in wishing him all the best for the future.
Before riding off into the sunset, I would like to thank everyone who has supported the nursery over the years and I hope that you will all continue to do so under James's stewardship.

Habitat characterization of two Pinguicula species (Lentibulariaceae) in the western Alps
Background and aims – The habitat conditions and population characteristics of the Italian members of the genus Pinguicula are presently still scarcely known. In this study we carried out a comparative research on two butterwort species occurring in the same mountain area, but very different in their distribution, the endemic of the western Alps Pinguicula arvetii and the circumboreal P. vulgaris.
Methods – We sampled 36 stands of P. arvetii and 29 stands of P. vulgaris with squared plots of 0.25 m2. In each plot we collected data on geology, topography, hydrochemistry and soil, made a complete inventory of plant species, used for calculating the Ellenberg indicator values, and assessed population density and proportion of flowering individuals. Moreover, we calculated indices of size of vegetative and reproductive structures. We compared the environmental characteristics of sites occupied by the two target species and performed ordinations to assess differences in habitat conditions and to analyse the relationships between characteristics of the two butterworts along environmental gradients.
Key results – The two butterworts showed significant differences in site elevation and in most of the ecological indicator values. Consistently, the analyses of species composition of stands revealed that the endemic P. arvetii occurred more commonly at higher-elevation habitats, characterized by a greater incidence of species typical of snowbeds, screes and sandy and skeletal poor grasslands. Individual and population characteristics differed in their position along the ordination axes, with a negative relationship between population density and proportion of flowering individual in both the Pinguicula species.
Conclusions – The main environmental variable discriminating sites occupied by the two butterworts was the elevation. Growth and reproductive performances of the two Pinguicula species were influenced by site conditions, but environmental gradients differently affected individual and population characteristics of the two target species.
