  • 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.

  • 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.

  • Pieris Japonica – Andromeda

    Pieris japonica  is a hardy evergreen flowering shrub that has distinctive new red leaves early in the season. These new red leaves turn yellow then green as they mature. Certain cultivars can have very dark red leaves.

    • Plant Family – Part of the Ericaceae family or heath family, same as rhododendron, heathers, cranberry and blueberry, and my favourite bilberries. 
    • Native to – These flowering plants are native to China, Taiwan and Japan, especially in the mountainous regions.
    • Common Names – It is often called the Andromeda. 
    • Flowers – The flowers are small and bell shaped, similar to lily-of-the-valley. Colours ranging from reddish pink to white.
    • Foliage – The leaves usually start red when they first emerge, fading to yellow, light green and through to dark green as they mature. Being evergreen the leaves are glossy and leathery in form.
    • Height and Spread – Typically a slow growing shrub that can stay within 3 to 6 feet tall and wide, although they can develop into a more straggly, woody tree up to about 12 feet.
    • Position – These plants thrive in a shaded or partially shaded location with a well drained soil, acidic side. This makes them ideal in a woodland garden, or any moist, shaded and cool position. Too much sun or frost can scorch the leaves and turn them brown. They need regular water in dry conditions but don’t like soggy wet conditions.

    Overall, in the right position they can be a trouble free, easy to maintain plant that gives a splendid splash of colour in the spring and maintain its foliage all year round. Just remember it is an acid loving plant and if you have neutral or alkaline soil it will require specific acidic feed to keep it going.

  • 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.

  • 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.

  • 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.
