It has rained a lot in the last couple of days and then today the sun came out again.
I found a few interesting things today and so I am going to start with female plants of the Dog’s Mercury.
I need photographs of the flowers. When I wrote about Dog’s Mercury earlier in the year, this was the best picture that I could find of the female flower.
It is not easy to photograph the flowers, they are small and they tend to lie under the leaves but this is what I got today.
You are not missing anything, there just isn’t very much to the female flower. Three green tepals open and inside there is just a two lobed stigma, (until the ovary develops). I will work on getting some better pictures 🙂
The male flowers are a little bit easier, at least they don’t hide themselves away.
This next one is Hairy Bittercress.It is only when I got home and looked at these pictures that I realised the seed pod at the back of this next picture looks fit to burst, it is something else that I must photograph.
It was a bit disappointing today, I saw several but I just couldn’t get close to them. I put it down to coming out at lunch time on the hottest day of the year, so far. They had too much energy.
I saw two Red Admirals and then a Small Tortoiseshell. I chased them up and down the track for ages, our walk took four hours today.
Fizz looked after my hat while I chased the Butterflies.
Come on Fluffy, back to the flowers.
It is Wild Garlic. I won’t dwell on this today because I don’t think my photographs were very good. I need to get decent pictures at this early stage and then I need to eat them. We will be back here soon.
This is a dog tired Dog.
I wrote about Snowdrops for EW. It was a frustrating task because I wrote this post last year but I knew that it wasn’t good enough and that I would have to rewrite it.
It took me about twelve hours to do 900 words but it is done now.
The Snowdrops around here are fading fast but hopefully this will be all right for next year 🙂
The Common Snowdrop isn’t native to the UK it is naturalised, that means that it is an introduced species that probably arrived here around about the sixteenth century and has been here ever since. Most people think of it as a native species today.
Galanthus nivalis is native to most of Europe and that is where we got it from.
There are twenty species of Galanthus Snowdrops native to Europe, the last one only being identified in 2012. They all look very similar but the most common species is G. nivalis, the Common Snowdrop.
Identifying the Common Snowdrop:
Galanthus nivalis has narrow leaves (6mm or less) all of the other known species have leaves at least 9mm wide.
So there is a simple rule of thumb.
If the leaf blade is thinner than your little finger nail then it is Galanthus nivalis, if it is wider then it is one of the others.
There are dozens of garden varieties that have been cultivated from G. nivalis and so they all have the same narrow leaves. They have names like Galanthus nivalis “Green Tear.” These varieties have been selected because they have some striking difference to the Common Snowdrop and usually that concerns colour or shape.
The flower of the Common Snowdrop is composed of six “tepals.”
(Tepal is a word that we use when the petals and the sepals appear the same or are performing the same function)
The three outer tepals are plain white. The three inner tepals are half the length of the outer ones and they have a green mark at the tip that looks like a little bridge.
To complicate matters further there is a double Common Snowdrop that grows in the wild and can often be found growing amongst the single flowers. It is called Galanthus nivalis f. pleniflorus “Flore Pleno.”
So to summarise my “Easy” identification guide: If the leaf blade is thinner than your little finger nail, then it is Galanthus nivalis and if it has that little green bridge mark and nothing else, then it is almost certainly just a Common Snowdrop.
If you would like to view some of the many variations on this theme then I would recommend a visit to Judy’s Snowdrops. My link will take you to a page showing G. nivalis cultivars but the whole web site is worth exploring if you have the time.
There is one other identification feature that I should mention, The leaves of the Common Snowdrop face each other like a pair of hands clapped together, in a few species the leaves wrap around each other at the very base. I think that for our purposes this is a bit academic, it is enough to do the finger nail test.
The Common Snowdrop description:
The Common Snowdrop has a single flower on a stem (sometimes called a “scape”). As the flower breaks through the ground it is protected by two bracts with hardened tips and the flower lies between them enclosed in a papery spathe.
The flower is composed of six tepals, (petals) three outer and three inner. The outside tepals are white. The inner tepals are half as long as the outer and bear a green mark that looks like a little bridge.
The inside of a Common Snowdrop looks like this.
This is the fruit of the Snowdrop, it will contain two or three seeds. The flowers die and drop off in early March and the leaves die back soon after but the seeds won’t be ripe until June. Until that time the fruit will lie on the ground, it will yellow when it is ripe and then it will open.
The French call this little flower perce-neige which literally translates as pierce-snow. The tips of the leaves are hardened to allow them to break through the cold frosty ground.
Kew Gardens have been monitoring the arrival of the first Snowdrops since the 1950’s and at that time Snowdrops opened late in February, by the 1990’s they were opening in January. In 2014 Kew announced their first Snowdrops on December 5th. Winters really are warming up.
The Snowdrop flowers very early in the year, when there are few pollinating insects around, as a result the plant usually spreads by vegetative means (from the small bulblets that form at the base of the main bulb) rather than from seed production. However they will last into March and do provide a very valuable source of nectar and pollen for early Bumblebees, Honeybees and other insects.
Snowdrops react to the sun. On a warm sunny day they open their outer tepals wide and release a scent that is like warm honey. They are doing their best to attract any insects that are around.
