Achillea or Yarrow – Colourful Flowering Border Plants

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.

Gazania or African Daisy – Vibrant Hot Colours

Gazania or African Daisies are bold, bright flowers with hot colours that are suited to sunny, dry climates. Although being in the same family, they are a different genus to Osteospermum plants that are also commonly referred to as African Daisies. These plants are drought tolerant and like to have full sun to be at their best. Being in the shade will make the flowers close and may then grow thin taller stems unable to support the large flower head.

Leucanthemum vulgar – Oxeye daisy everywhere

Oxeye daisy is now everywhere. It grows in abundance on the roadside verges, river banks, parks and any grassy areas that suit. They prefer a sunny location with well drained soil, and that means they will be at home on any south facing embankment, proliferating at the expense of most other flowers. Still a welcome site that cheers up the green landscape, or brown as it is becoming at the moment.

Leucanthemum vulgare or Oxeye daisy are part of the Asteraceae family with the typical daisy like flower head of white petals with a bright yellow central disc. This disc contains many nectar filled flowers that attract bees, butterflies and many other insects. So, good for the biodiversity, as long as they don’t completely dominate an area.

Armeria maritima – Sea Thrift

Armeria maritima is a hardy perennial plant that grows in clumps and flowers from spring to summer with shades of pink that are best seen en masse.

Plant Family – Part of the Plumbaginaceae family or leadwort family.
Native to – These flowering plants are native to the coastal regions of the Northern Hemisphere.
Common Names – It is often called Sea Thrift or Sea Pink. The word thrift evidently comes from an Old Norse word meaning to thrive. Very apt for this plant as it makes the very best of rather poor ground to produce a display that will lift the spirits.
Flowers – The flower heads are formed in a round cluster on top of a thin but sturdy stem. The small flowers are various shades of pink. They remain upright on the thin stems to maintain a fine display.
Foliage – The dark green, glossy needle-like leaves form a clump or carpet from which the flower stalks grow to form a canopy.
Height and Spread – These are a low growing, ground cover plant that grow to a height of up to 18 inches, mostly shorter than that. They tend to spread over time into a cluster and form a carpet that accentuates their beauty.
Position – These plants thrive in full sun location with a well drained soil, from acidic to alkaline. This makes them ideal for a rock garden, coastal gardens, but can also fit into any well-drained border or even a living roof.

Overall, a plant that will cope with poor conditions to produce a flowering display and survive year on year with little maintenance.

Antirrhinum – Snapdragon – border annual for a blaze of colour

Antirrhinum, commonly known as snapdragons, are a bright, bold colourful flowering border plant. The name “snapdragon” comes from the unique shape of the flowers, which resemble the face of a dragon that “snaps” open and shut when squeezed. The name Antirrhinum comes from the Greek, anti or opposite (or fake) and rhinos or nose. So again being like an animal’s mouth.

Antirrhinum, or snapdragon, is a genus of flowering plants in the family Plantaginaceae. These plants are native to Europe, North America, and North Africa. Whilst they are generally annuals, some are perennials or even sub-shrubs. They generally have a long flowering season from early summer to mid-autumn. Flowers start to bloom from the bottom of a thick stem and continue to bloom right up to the top. To keep them looking their best you can dead-head regularly once the lower flowers are looking spent.

Genus

Do snapdragons like shade or sun? The answer to that is more complex. They can tolerate full sun or partial shade, as long as it is not too harsh. They do not have resilience to hot and dry climates but rather they like cool sun, moisture but well drained.

They are also known to attract pollinators like bees and butterflies, so can add to the overall biodiversity of your garden or border. In addition to their ornamental appeal, snapdragons can serve practical functions in the garden. They can act as a natural deterrent for certain pests due to their strong scent. Planting them near vegetables or herbs can provide a natural repellent effect, thus protecting your crops. This symbiotic relationship between flowers and food plants can create a healthier garden ecosystem.

From a size perspective, they can range from 6 inches to 3-4 feet high. So choose your plants carefully, and plant in the right position to maximise the flowering display in relation tote other plants around them. Depending on how far back in the border they will be to give that layered look to the border. Dwarf varieties, of course, are perfect for the front of border.

As an annual plant, snapdragons usually complete their life cycle from seed to seed in one growing season. They can be used as cut flowers, making them a popular choice for bouquets and arrangements. When cut, snapdragons can last up to two weeks in a vase, allowing their beauty to be enjoyed indoors as well.

Snapdragons can be grown from seeds, which should be sown indoors 8-10 weeks before the last frost. Alternatively, once the threat of frost has passed, they can be directly sown outdoors. Plants should be given adequately space to allow for their growth, typically around 6 to 12 inches apart, depending on the variety.

Modern varieties can be resilient but take care of aphids and diseases such as rust, mildew and wilt. Having Ladybirds/bugs around will help with the aphids. The diseases will require you planting in the right environment to control moisture and not spread disease from one plant to another. A correct balance of heat, breeze and moisture is important to avoid such disease.

Snapdragons are not just beautiful; they also have a rich history. Once a staple in English gardens, they were often used in herbal remedies. The flowers were believed to possess medicinal properties, and despite their beauty, they were a key ingredient in various potions. Today, they continue to symbolise grace and strength in floral arrangements, making them a favourite among florists and garden enthusiasts alike.

Spear Thistle – Cirsium vulgare

Spear Thistle – (Cirsium vulgare, family: Asteraceae), also known as Common Thistle. This tall flowering biennial plant has a very distinct shape and is commonly accepted as the ‘flower of Scotland’. Considered by many people to be a weed and certainly be called so if you get a prick from its spear shaped thorny leaves. One of the types of plant that was said to proliferate outside the ‘garden of eden’.

In flower it is one of the best nectar providers in the UK and loved by the pollinators. Native to most of Europe, Western Asia but also naturalised in many other parts of the world it is part of the large Asteraceae or daisy family.

Once the flowers have died back it produces a woolly seed head that gives further visual interest but also acts as an efficient seed dispersal mechanism used by many plants, shrubs and trees.

Crinodendron – Lantern Tree of Chile

Crinodendron is a genus of evergreen shrub or small tree native to the forests of Chile. They have crimson or pink lantern-shaped flowers that, unusually, hang under the branches. These are partly hardy plants that will tolerate a minor frost but do best in part shade in well-drained, humus-rich acid soil.
