Convolvulus arvensis – A Pain In The Grass

Convolvulus arvensis, commonly known as field bindweed, makes a pretty show in the local wildlife meadow. However, if it’s allowed the space to prosper, it can be a real pain to subdue. If it invades farm crops then it can be hard to eradicate and cause loss of production.

It is one of many species in the family Convolvulaceae or bindweed family. In the garden we mainly see its bigger brother, the giant bindweed (Calystegia silvatica), that grows higher and further than the field variety.

Field bindweed has smaller pink and white flowers, less trumpet like, and smaller arrow-shaped leaves. It grows close to the ground and in a meadow situation has many more vigorous plants to compete against. Still, makes an attractive plant in the right situation.

Aquilegia – Columbine – Granny’s Bonnet

Aquilegia, commonly referred to as Columbine or Granny’s Bonnet, is a quintessential element of any cottage garden, woodland garden, or border display. Its medium height and striking appearance allow it to harmonise beautifully with neighbouring plants. With a stunning variety of colours and unique forms, it captures the eye and offers endless pleasure to those who take the time to observe its intricate beauty. This plant not only enhances garden aesthetics but also plays a vital role in supporting local ecosystems by attracting a diverse range of pollinators.

Granny’s Bonnet: A Colorful Addition to Your Garden

Known for its unique flower heads, this plant gets its common names, Columbine and Granny’s Bonnet, from the distinctive shape reminiscent of a dove’s head or a traditional bonnet. The name Columbine comes from the Latin word columba, meaning ‘dove,’ while Aquilegia is derived from the Latin word aquila, meaning ‘eagle,’ reflecting the spurred petals that resemble talons. These striking flowers bloom from late spring to early summer, providing an interesting diversion from the big bold blooms.

This fascinating genus within the family Ranunculaceae includes Buttercups. It is easy to see the similarities, but the intricate forms of this flower provide a much more interesting specimen. There are about 130 different species that explore different colours and nuances of petal shape, each with its own unique characteristics and charm. From the delicate blue and white varieties to vibrant reds and yellows, the options are nearly endless.

Modern hybrids are particularly captivating, often featuring two layers of petals in contrasting colours, creating a visually stunning effect. The spurred petals that extend behind the flower head add to the unique aesthetic of the plant, making it a favourite among gardeners and flower enthusiasts alike. The colour palette is extensive, including shades of purple, red, pink, white, yellow, and blue. This diversity allows for creative combinations in garden designs where they will complement similar plants.

Native to various regions, especially the temperate zones of the Northern Hemisphere, Granny’s Bonnet thrives in diverse climates and conditions. Its ability to self-seed makes it an excellent choice for wild gardens, as it promotes natural growth and attracts pollinators such as bumblebees, butterflies, and hummingbirds. In favourable climates, the presence of this plant can significantly enhance the biodiversity of a garden, benefiting both the plants and the wildlife that depend on them.

The height of these plants can vary, ranging from 1 to 3 feet depending on the specific variety and growing conditions. Their slim profile allows them to occupy minimal ground space, making them ideal for borders or mixed plantings. While they prefer a little shade from intense sunlight, they can tolerate full sun in cooler regions. A temperate climate with adequate moisture is essential for optimal growth, as they thrive in well-drained soil that is neither too wet nor too dry.

Another important aspect to consider is the companion planting of this species. It pairs well with a variety of other flowers and greenery, enhancing the overall aesthetic of the garden. For example, planting alongside Foxgloves and Delphiniums can create a beautiful layered effect, with each plant contributing its unique shapes and colours. Moreover, these companion plants often have similar care requirements, making garden maintenance more manageable.

In conclusion, this remarkable plant offers not only beauty but also ecological benefits. By understanding its unique characteristics and care requirements, gardeners can create stunning displays that contribute to the health of their local environments. Whether you are a novice gardener or an experienced horticulturist, incorporating this species into your garden can lead to a more vibrant, diverse, and sustainable landscape.

Callistemon or Red Bottlebrush Plant

Callistemon is a genus of exotic flowering plant from the Myrtle family, Myrtaceae. Commonly called the bottlebrush plant for obvious reasons.

Currently, there is a debate as to what plants should be specified as Callistemon and those that are a closely related genus, Melaleuca. It appears that on DNA evidence alone most Callistemons are in fact Melaleucas. This is disputed due to differences in physical make-up of the flowers. This has been going on for over 150 years so still a work in progress.

What is the difference between Melaleuca and Callistemon?

The two genus both belong to the Myrtaceae family but historically have been kept separate because of certain characteristics of the flower. In both cases they can look like a ‘bottlebrush’, ie. A brush for cleaning bottles with. The stamens growing in clumps from the central woody branch with just a small petal array at the base of each clump.

The melaleuca was defined by the difference that these multi-stamen flowers had stamen that are fused into small groups at the base, whilst Callistemon doesn’t. That isn’t a valid difference in every case. For instance Callistemon viminalis (Weeping Bottlebrush) has stamen that are also fused into small groups at the base.

Recent use of DNA testing has shown that these two genera are more closely connected than was originally assumed. Most botanists will take one side or the other, follow the DNA or stick with the visible characteristics and keep the two genera separate. Where I live, if they look like a bottlebrush, they will be referred to as Bottlebrush for a long time to come.

Agapanthus – African Lily – Tall Globe Shaped Flower Heads to Lift a Summer Border

Agapanthus plants are tall with a globe of flowers on a single stem, not unlike their cousins, Alliums, and Amaryllis. Predominantly blues, purple and white with bigger more dramatic flowers than Alliums. Native to Southern Africa, and commonly called African Lilies although they are not Lilies at all. They love the sun, well-drained soil but can also stand some drought. Ideal for keeping in pots as you can control spread and concentrate the flowering.

Allium – Ornamental Onion – Bold Architectural Blooms

The Allium is a tall pompom flowing plant of the Garlic-Onion family. Predominantly purple or white with a globe head of fine star-shaped flowers. They are easy to grow but like the sun and good drainage as the bulbs can rot in heavy wet soil. They do stand out when isolated in a border but also look very good when planted in large swathes. The name Allium is Latin for Garlic and is thought to derive from the Greek word meaning avoid.

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.
