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.

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.

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.

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.

Aeonium Arboreum – Tree Houseleek – Succulent Plant with Large Colourful Rosettes

Aeonium arboreum or Tree Houseleek is a subtropical succulent plant native of the Canary Islands and Madeira but has spread to the Iberian Peninsula and North African coast. They make good houseplants and can be grown in patio pots in a sunny position. They should be covered or brought indoors when temperatures fall.

Anemone – Japanese Anemone – Easy to Grow Tall Perennial

Japanese Anemone are perennials that are characterised by tall stalks and flat wide single flowers in an array of different colours. They are simple to grow but in heavy shade tend to get leggy and require support. This is especially true for the Japanese Anemone but there are varieties such as the ‘wood anemone’ that grow closer to the ground and ideal for more shady areas.

Popular hybrids like the ‘Richard Ahrens’ can grow up to 1 metre tall and has flowers of 7-8cm across. The contrasting pale pink with dark pink edge and vivid yellow stamens make a pleasing contrast with lush green surroundings. They are easy to grow and will spread if not restrained.

In the winter they will recede back to the tuberous roots and re-appear in the spring provided the roots have not been waterlogged.

Due to their height and little need for attention they are a good option for mid flower border or informal cottage garden and will attract insects and other wildlife to add to the an overall healthy ecology.

Meconopsis – Himalayan Poppy

Meconopsis is a genus of flowering plants belonging to the family Papaveraceae or Poppy family. These plants are often known for their beautiful blue petals, but they also come in a variety of purple, white and yellow. Commonly referred to as Himalayan Poppy as they are found natively in the Himalayan Mountains. Given their natural habitat, these plants are fairly hardy, but remain difficult to because being monocarpic they only flower and set seed only once.

Meconopsis Taxonomy

The name comes from the Greek for ‘poppy like’, and so other Poppy type flowers were Meconopsis genus. Most Poppies are listed in their own Papaver genus, Papaver being Latin for Poppy, but the Meconopsis genus is kept separate for these Himalayan flowers. All poppies belong to the Order Ranunculales, or Buttercups.
