There Is A Something To Like About Grevilleas
Grevilleas are, without a doubt, one of the most well-known Australian plant families. They require little maintenance, use little water, and produce beautiful flowers.
Most species also have the added benefit of luring birds and insects with their profusion of nectar.
Grevilleas are named in honor of Charles Greville, a founding member of the Royal Horticultural Society and a friend and supporter of numerous botanists in the 18th century, including Sir Joseph Banks.
Grevilleas come in a wide range of heights, from low-growing, prostrate plants to enormous trees like the 30-meter-tall G. robusta.
Main Varieties Of Grevillea
This Grevillea, often called the Silky Oak, is frequently cultivated as a focal point in expansive gardens where its grey bark, dark green, ferny foliage, and gorgeous golden/orange blossoms may be wholly appreciated.
Grevillea thelemanniana, an exceptionally exquisite specimen at the low end of the height scale, comes in various forms, from shrubs to those with a prostrate growth habit.
Grevillea t., also known as the spider net grevillea due to its finely divided foliage, is a naturally occurring plant in Western Australia primarily restricted to the Darling Ranges.
It has clusters of pink or red flowers with yellow tips and beautiful dark green, lacey foliage.
Although it is known to adapt to other soil types, it may be found growing in alkaline, sandy soils, so it should do well under similar conditions in cultivation.
This adaptable grevillea has many uses in gardens, especially in drought-tolerant landscaping projects.
Along with the taller varieties, there are prostrate and low-growing varieties, such as G. ‘Baby,’ G. ‘Green Gem,’ which has darker foliage, and G. ‘Mini Mavel,’ which has denser growth.
Use And Maintenance Of Grevillea
The proper arrangement can be used to great advantage to create the appearance of depth in a tiny garden. As groundcovers, they aid in inhibiting the growth of weeds and serve as a living mulch to conserve moisture.
Although they will thrive in a shaded area, grevilleas prefer the sun; if grown in the shade, they get lanky and produce fewer flowers.
Grevilleas dislike having their feet wet; therefore, it’s crucial for healthy, robust plants to grow on soil that drains rather well.
They will grow well in a clay loam as long as it is well-drained, so this does not imply that you need sandy soil.
A question always asked is what the best Grevilleas are for a Winter flowering garden to attract birds to the garden.
