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.
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.
Acer palmatum or Japanese Maple provide excellent colour and structure to the garden. Green, yellow, orange to dark red, they help to break up a sea of greenery. Colours changing through the season and bare skeletons in the late autumn and winter months.
Here in our focus image, we have two similar but distinct varieties. The name palmatum comes from the similarity to the human hand or palm with leaves spread out like fingers. These fingers can be dissected as in the far Acer or doubly dissected as in the near Acer. The double dissection making the leaves like feathers.
There are also two basic structures here. The far Japanese Maple is an upright Acer, whilst the near is more of a weeping Acer. The weeping structure provides a pleasing dome shape to the plant.
Helleborus orientalis is a hardy perennial plant that will flower early in the growing season and provide some colour and interest In the garden border even when the spring temperatures are chilly.
Native to – These flowering plants are native to Greece, Turkey and the Caucasus, especially in the mountainous regions.
Common Names – It is often called the Lenten rose due to it flowering throughout the calendar period known in ‘christian’ lands as Lent.
Flowers – The flowers are, as most Buttercups, a cup shape and are many shades of maroon, purple, pink, white and even a green tinge. They tend to droop and face the ground once fully bloomed.
Foliage – The dark green, glossy leaves grow in a rosette form around the main stem with the flower emanating from the centre. These leaves are palmate, dissected into long this fingers with sawtooth edges. The stems are thick and hardy. Once they have flowered the leaves will last throughout the winter, gradually turning brown and drying out. These can be pruned back to keep the plant looking fresh or just left to wither and decay, depending on the look you want produce.
Height and Spread – Typically grows to a height of 12 to 18 inches and can spread about 18 inches. These plants tends to spread over time into a cluster.
Position – These plants thrive in a shaded or partially shaded location with a well drained soil, more on the acidic side, but tolerant of alkaline. 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.
Overall, Hellebores are an ideal flowering plant that can be left to grow year on year, in the right conditions, and provide an interesting feature before many other garden flowers have emerged from winter.
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.
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.
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.
