  • 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.

  • Calceolaria or Slipper Flower

    Calceolaria are a genus flowering plant from the family, Calceolariaceae. Commonly called the Slipper Flower, Lady’s Purse and Slipperwort, due to unusual flowers that resemble slippers or purses and calceolaria being from the Latin for shoe. Currently, there are only 3 genera in its family, although others may soon follow as modern dna analysis is re-classifying plants into their families. There are over 388 species of Calceolaria and that covers a wide range of different plants

    Natively, these plants are found mainly in the Andes Mountains but also anywhere from Southern Patagonia to Central Mexico. Many modern hybrids can be found to brighten up garden pots and hanging baskets.

  • 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.

  • 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.
