Coming across a brightly coloured flower, standing out in a harsh stoney environment does bring a smile. This Calendula or Pot marigold, is a member of the Asteraceae family and has the typical daisy flower head. Native of southern Europe it now cultivated for gardens across the world and has uses other than its obvious ornamental value.
It has uses in the kitchen as parts are edible, such as the petals can be used in salads. It has uses in medicine as an anti-inflammatory and has skin healing properties. Compounds from Calendula can be found in cosmetics too, but can cause an allergic reaction.
May brings out this early flowering Tamarisk – Tamarix tetrandra uk – in cascades of feathery pink blooms that brings beauty to any suitable garden. As a native of hotter and drier climates where arid land, including salty coastal areas prevail, it doesn’t seem like a plant suited for the UK. However, being so versatile it can grow well in a sunny, well drained spot, with natural defences against the heat, wind and salinity.
It is one of the many flowering shrubs that require pruning just after flowing as the following years flowers develop throughout the growing season. The shrub grows to it’s full potential of 2-4 meters over a couple of decades depending on how ideal the conditions are.
Achillea or Yarrow is a species of the family Asteraceae, commonly known as the daisy family. It has many small flowers in a cluster at the top of a thin stalk arising from the base plant and extending high towards the sunlight. It is a native, common wild flower but has many species and cultivars to expand on the basic wild variety.
The name Achillea is from Greek mythology as the leaves were used to treat the wounds of Achilles’ Soldiers. It has many other common names that relate to its medicinal use to heal wounds and stop blood flow.
Achillea or Yarrow, when not in the wild, is a tall flowering plant used in borders of cottage or wildlife gardens. Due to its height and slender form it can compete for space and thrive alongside its neighbours. It best sits mid border and provides clusters of small colourful flowers, tightly packed and resilient. Without neighbouring plants to help it may need support to keep it up and looking its best.
In the natural form the flowers are usually white and clusters as a tightly packed head at the top of the rising stem. There is now a wide variety of colours, from deep reds and pinks through orange, yellow and white. Easy to grow perennial that will keep spreading over time.
The leaves are fern like or feathered, frilly or hairy, and mainly come from the base but also interspaced up the main shoot that holds the flower head at the top. These leaves are often aromatic and edible in small quantities.
Achillea or Yarrows are very tolerant border perennials that can do well in most situations but don’t like heavy, wet soil. They are native to more temperate climates of the Northern Hemisphere.
There are more than 1000 named species, sub-species, or varieties assigned to the genus of Achillea. Two popular species are the Achillea millefolium, common yarrow, and the Achillea ptarmica, sneezewort. Generally, the millefolium has smaller and more tightly packed flower heads, whilst the ptarmica has larger more openly spread flower heads.
Achillea is a good plant to consider for not only its form and long flowering colourful displays, it is very attractive to insects that promote a wider pollination to improve biodiversity, but also has medicinal healing properties that have long been used to treat many different ailments.
Hemp-agrimony – (Eupatorium cannabinum, family: Asteraceae), also known as holy rope. This tall hemp-like flowering perennial plant certainly makes an attractive sight but is also a favourite with the butterflies. Native to most of Europe, NW Africa and Central Asia it is part of the large Asteraceae or daisy family.
Although called a ‘hemp’ and the Latin name suggests a link to the Cannabis plants they are not closely related and not used in the same way. They do have a history of medicinal use as anti-inflammatory and for healing wounds. Otherwise an attractive flowering plant.
Biodiversity expresses the richness of life on earth in all its complexity and order. It encompasses all types of life from the very basics to the most complex organisms. So how do we decide if biodiversity is healthy or in decline?
Anecdotally, I have noticed a decline in the gardens and woodlands around me. However, when there are lots of bugs in the air there seems to be a lot of just one sort at any one time. I suppose this will happen but doesn’t bode well for the future. Infestations, swarms and outright Biblical plagues may be to come.
Whatever, we need biodiversity and monitoring is essential to understanding where human behaviour is affecting it. Positively or negatively.
The Persian Cornflower in its cultivated form has a striking colour and a beautiful shape. Vivid pink and opens very similar to a thistle shape. Some have a white or cream centre, but in this particular cultivar the centre carries the main colour.
Persian Cornflower not your average Daisy
As part of the Asteraceae family, one of the largest, it resembles so many other members. However, this is likely best classified as a Psephellus dealbatus and not Centaurea. The plant is native from Turkey and up through the Caucasus but introduced to much of Northern Europe.
This plant loves full sun in nutrient-poor but well-drained soil. This makes the plant ideal for a cross between border, cottage garden or pseudo mediterranean garden that is not too hot or dry. Definitely more impressive than the common cornflower.
I came across an unusual tree that in the cold north wind was depositing fluffy chaff. Not recognising it, I used the Seek app to see what it was. Evidently it is called the Manna Ash, or Fraxinus ornus. Obviously the manna refers to the Biblical manna that the Israelis fed on in the wilderness. However, the link I made was from all the white chaff falling on me. Rather, the reason it is called the Manna Ash is more to do with the sweet sticky sap that comes from the bark. Anyway an interesting part of the Ash family.
