The Daisy family, Asteraceae, is the second biggest and provides some of the best loved flowing plants we have. Cosmos are well ordered flowers with fine featherlike leaves that stand tall. The name Cosmos comes from the Greek for ‘ordered world’.
They are well ordered and keep their form, even when massed together, giving a super colourful display in any border. Colours range from chocolate, through orange, magenta, pink and white. All with a yellow centre with radial petals, like little solar systems or galaxies in perfect synchronisation. A very apt name, Cosmos.
In a local water meadow the White Poplar, populous alba, has come back to life. The air is heavy with fluffy white ‘cotton’ that covers the ground nearby. This is the seed dispersal method of a lot of similar trees in the Willow family, Salicaceae. Once pollinated they blow off in the breeze to find space to grow.
The White Poplar is not native to the UK but has been naturalised over most of the UK. It loves water and can grow in the salty winds of coastal areas, too. The leaves are silvery underneath and darker green on the top. Unlike the long slender leaves of it cousin willows, these leaves broader and crenate at the edges.
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.
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.
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.
