I visited in June this area of natural beauty, called Aekingerzand. You can find it in the NW part of Drenthe with the border of Friesland. The photo is handheld made. In a little fen I found dozens Sundews. Because this plant is very tar, I have nothing from its surroundings removed for the photo. I hope you like it and thanks for viewing. With many thanks to Gert Paassen for the right ID.

Some info about this plant from Wikepedia.

Morphology

D. intermedia is a perennial herb which forms a semi-erect stemless rosette of spatulate leaves up to 10 cm tall. Plants in temperate regions undergo dormancy during which they form a winter resting bud called a hibernaculum.

As is typical for sundews, the leaf blades are densely covered with stalked mucilagenous glands which secrete a sugary nectar to attract insects. These then become ensnared by the mucilage and, unless they are strong enough to escape, are suffocated by the sticky goo or die from exhaustion. The plant then secretes digestive enzymes from sessile glands and later absorbs the resulting nutrient solution to supplement the poor mineral nutrition of the plants natural environment.

D. intermedia blooms from June through August, forming up to 15 cm. tall inflorescences bearing 3-8 white flowers. Fertilized ovaries swell to form egg-shaped dehiscent seed capsules which bear numerous tiny seeds.

Distribution and habitat

D. intermedia is one of the most widely distributed species in the genus, and one of only three Drosera species native to Europe (the others are D. rotundifolia and D. anglica). It is also found in eastern North America, Cuba, and northern South America. The Cuban and South American forms are tropical and do not form hibernacula in the winter.

D. intermedia grows in constantly moist to wet bogs, fens, and marshes. It prefers nutrient free soils - such as sphagnum peat moss or sandy ground - and open, sunny habitats.

Hello Bob,

I don't believe it is'nt that Sundew you mentoned.
These specie are upon 1 place in The Netherlands and that isn't Aekinger sand or Kale Dunes.
Sorry!
Good registration picture.
I think it are the Drosera intermedia.

Gert

Hi Bob,
This is a nice specie that I have never seen before. You capture good details and natural colors and those little droplets are a plus. The background is a little over exposed. I think that in this case, flash could have helped. It remains a beautiful and interesting picture. Greetings,
Claudine

Hi Bob,
how are you my friend? Good i hope. I love the colours and detail you have caught here, the water droplets add something special to this shot well done!
Paul

Hi Bob,
Interesting "insectivorous" plant with nice colors, and those water droplets add well.
Excellent notes, this is a great presentation mf.

Hoi Bob,
Ik was een aantal maanden geleden in de buurt van Raalte en daar had men net stukken heide afgeplagt. Het eenige wat daar toen in grote aantallen groeide was zonnedauw. Maar, de bosjes waren allemaal stukken kleiner en minder mooi dan deze. Het lijkt me dat deze meer op een constante plek groeien. Toch vind ik dit altijd weer een bijzondere plant die je niet snel verwacht in ons kikkerlandje.
Een mooie foto met een leuke creatief idee van de schuine hoek. Ook mooi dat je zelfs nog een half verteerde insect op de foto hebt.
Groeten,
Niek

Hi Bob,
This is a very good documentation of the Sundew plant.
The photo is from a great POV and has lots of good detail.
Your notes are very comprehensive too.
We have a Drosera similar to this in New Zealand but I haven't had much luck getting a good shot of it yet.
This one is great.
Cheers
Steve

Hi Bob, it looks like those plants that catch flies. And now, reading your notes - I see it is!!
I've seen them for sale in the plant shops, but we don't have them wild like this.
It is interesting to see it growing like this

Gert along with Ivan can be very helpful in ID'ing..I frequently rely on them for things of which I am just now learning...Very neat Shot bob...It has an eccentric pattern to it that is almost Pollack...Jackson that is...Tres' cool!
Bob

Hello Bob,
This is a very fine view of the Spoonleaf Sundew from an excellent POV and I love the striking red colour and the leaves against the light. Excellent sharpness and a fine composition.
Many thanks and best wishes, Ulla
