A brief description of the weeds with pictures by my partner Matt Summers, unless stated differently, follow below this introduction. Most weeds have been covered in a more detailed post in earlier posts and then mostly about their whole family for which there is a link on the start of each plant description.
Weeds are not at all bad; they are just inconvenient for us human beings!
Maybe we were just going to plant another more attractive plant in that place or maybe we desperately needed that exact spot for making a new drive for all our vehicles we need to park in front of our house? Or another more common reason is to just remove it as it looks aesthetically not pleasing to our tidy eyes!
Don’t worry I can just be as bad sometimes and not have a really proper reason for removing a weed…
But this is the exact reason why I write about them and try to make us see all their known good uses they got.
All their bad reasons for existence are mentioned already on many websites and this is hopefully not why you came to my site in the first place?
This is a one off blog about some weeds found in tropical countries. Most of those are actually exotics from other tropical climates which originally may have been introduced as an ornamental, just as in our own temperate world!
But you will be surprised that their are also temperate plants which can become weeds in the tropics!
My blog now got a big brother in the form of a short video each week about ten popular, or not so popular weeds!Watch the video below.
Last week we talked about the more prominent genera and species of the Polygonaceae, this week about the other group, which has one famousnon native weed: the Japanese knotweed!
As we have all heard about this infamous one I would like to explore a little bit about its positive site, if there is any, and if there is anything we can do about its spread.
Japanese knotweed (Reynoutria japonica) is a fast-growing and strong clump-forming perennial, with tall, dense annual stems. Stem growth is renewed each year from the stout, deeply-penetrating rhizomes (creeping underground stems).
It is a very costly affair to have it removed see more here:
What is now called The Fabaceae, was long known as Leguminosae and commonly these are known as the legume, pea, or bean family.
This is a large and economically important family in the world. It includes trees, shrubs, and perennial or annual herbaceous plants, which are easily recognized by their fruit (legume) and/or their compound, stipulate leaves.
In case there are any medical uses stated with the plants mentioned below, please take sensible advise from a qualified herbalist.
If you would like to learn a bit more about the classification of this large family I can recommend Britannica.com webpage
The background colour of the text indicate green for positive news and pink for negative news… In bold for quick reading and any other colour then green and pink used is to make it more pretty! Links are provided on medical or other difficult words.
These are the 3 other genera all with only one species native on the British Isles, which are also in the Betulaceae or Betula family I covered in an earlier blog-post!
Information for this blog is again from various websites, for more information follow the links on the plant names! Green background signifies all sorts of uses, blue background for wildlife and ecological uses and pink background is for medicinal use. Pictures by Matt Summers, otherwise stated.
After all the native, short, flowering plants, this time a blog on the native, tall, woody trees called Betulaceae, which includes the main genus, Betula or Birch but also our native Alder, Hornbeam and Hazel belong in this family.
The Betulaceae or Birch Family is number 59 in Stace and has 3 straight native species of Birch as well as several hybrids, subspecies and introduced, ornamental varieties.
The birch is a typical pioneer, which means it can colonize new land very rapidly in the right conditions and can therefore be seen as a weed by some who wouldn’t like them to do this!
But most of us can agree that the Birch tree is very beautiful and hoping for you to learn in the following text that it is also a very useful tree as are its cousins, Alder, Hornbeam and Hazel about which I will tell you more in the second part!
A green background of the text is for all uses and pink is for medicinal uses. Blue background for ecological interest. Pictures by Matt Summers unless stated
Today I will write the last part on our native Asteraceae or ‘composites’ and daisy family in common terms. All known medicinal uses and other uses are mentioned.
In the last post I covered with what we see as the common daisies: yellow centred disk flowered with a ray of white florets as well as a few other composites or Asteraceae.
This time we start with plants we don’t immediately associate with the composites, but closely observed we find always the common combination of many disc florets, surrounded or not with ray florets.
Then finishing off with the other typical group of the Asteraceae which are the various ‘dandelion like’ flower members!
Most information again from the Medicinal Flora by J. Barker. The links to the scientific and common name provide also with good, general information about the plants!
To make the post more colourful I have given the plant a background of the flower colour!
There is a green background for the text if the plant is edible, ornamental or otherwise useful for wildlife, etc. Pink background is either as a warning or medicinal use. Blue background for interesting facts!
MOST MEDICINAL PLANTS ARE ALSO TOXIC IN LARGE DOSE. Advice is to never self-medicate.
First of all: ARTEMISIAS OR WORMWOODS:
The Artemisias: There are less than a dozen native artemisias on the British Isles and it should be noted that they are CUMULATIVELY TOXIC AND IN OVERDOSE MAY CAUSE IRREPERABLE DAMAGE TO THE BODY!
Today I will list some of the commonly known ones in our temperate climate.
As I’ve already included pictures in the general blog on Asteraceae back in the summer I will only include links on both of the plant names so you will be able to read more about each plant on other useful websites.
I will also colour code the blocks on the colour of the flower. Hope you will find that useful as well as pretty! Most uses are medicinal. Plants used as an ornamental or other uses are backed by a green colour!
