  • 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.

  • Acacia dealbata – Silver or Blue Wattle – Mimosa

    Acacia dealbata is a evergreen shrub or tree that will flower early in the growing season in warm and temperate climates. 

    • Plant Family – Part of the Fabaceae family or Legume family that includes peas and beans. 
    • Native to – These flowering plants are native to southeastern Australia.
    • Common Names – include Silver wattle, blue wattle or mimosa.
    • Flowers – The flowers are bright acid-yellow that grow in clusters of small round balls.
    • Foliage – The foliage is fern-like and green with a blue or silvery grey hue.
    • Height and Spread – these tree/shrubs can grow quickly to a height of 30 metres, or 100ft tall with an equally wide spread.
    • Position – These plants thrive in full sun with a well drained soil, more on the acidic side, but neutral is fine. This makes them ideal in a sunny but sheltered location with a southern aspect and a reasonably mild climate.

    Overall, a striking plant that will look attractive all year round with a splash of colour in the early seasons.

  • 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.

  • 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.

  • 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.
