Charming hydrangeas in a home garden
Photo, taken during the writer's time in New Zealand, shows the hydrangea blooms.
HYDRANGEAS are among the best-loved flowering plants in gardens around the world.
This species is known for its lush, voluminous blooms and wide range of colours.
Hydrangeas also symbolise grace, beauty and heartfelt emotion.
Native to Asia and the Americas, these flowering shrubs have become popular in both traditional and modern landscapes due to their striking appearance and relatively easy care.
My own experience of growing hydrangeas, though, has given me enough headaches and smiles for a long time!
The biggest headache is our hot climate – hydrangeas do not like the tropics.
I have seen the bountiful and super-beautiful blooms in the temperate climate down in Christchurch and almost all regions in New Zealand, where they are grown easily outside the gardens and on the fences, giving all the colours that you want in the garden.
There are over 70 species in the family Hydrangeaceae. The most commonly-grown types include the Hydrangea macrophylla, Hydrangea paniculata or 'panicled' hydrangea, and Hydrangea quercifolia.
Hydrangea can be evergreen or deciduous, and may grow as shrubs or vines.
Its most notable feature is its large, globe-like flower clusters. The blooms can vary dramatically in colours, including shades of white, pink, blue, purple and even green.
Interestingly, the colours of Hydrangea macrophylla are influenced by the soil PH level.
Acidic soils (below pH6) produce blue flowers, while alkaline soil often yields pink or red blooms.
Lime in the ground would lock up aluminium sulphate and other elements around the root sphere, and with watering that can make the blooms turn blue.
There are several other varieties that produce blooms in various shapes instead of the normal global ones; some hybridised between Hydrangea macrophylla produce 'blue wave' – making the bloom with a ring of blue floret on the outer ring, and mini-inflorescences in the centre.
Hydrangeas thrive in well-drained moist soils rich in organic matter. They prefer partial shade, but can tolerate sunlight in the cooler climates.
In Sarawak, it is better to provide sun-shade up to 60 per cent coverage, and to keep it cool.
My neighbour places the pot-planted hydrangeas along the veranda, which only receives the morning sun from the east.

Regular watering is necessary, if the weather is not rainy.
Hydrangeas are sensitive to drought – the large foliage wilts under dry condition.
Pruning is required to maintain condition and encourage new wood to bloom.
Shortage of iron element in the medium can cause rust patches on the leaves, and this can be relieved by the addition of high iron fertilizer.
The plant would need more balanced fertiliser to ensure good growth and continual blooming, especially when it is pot-planted.
Besides landscaping and decoration, hydrangeas carry a range of meanings in various cultures.
In Western floral symbolism, hydrangeas can represent grace, beauty and abundance, though they are also associated with vanity owing to their lavish appearance.
Caution though: all parts of the plant are toxic to humans and most pets due to the presence of cyanogenic glycosides.
Happy Gardening!

Gardeners urged to prune 10 plants now to ensure summer blooms
If you're looking forward to seeing your garden in bloom this summer, make sure you take time to prune these 10 plants to see them develop to their full potential Most garden -owners are anticipating a gorgeous display of blooms once summer is in full swing – but, beware, some flowers need to be pruned first. Pruning is a crucial task for the development of many plants, as it allows gardeners to sheer off any unwanted, damaged or dying blooms to make way for a much more robust blossom. This is because it forces the plant to redirect energy and nutrients to new blossoms. Equally, it helps prevent the spread of disease, as you can prune away any infected leaves, stems or blossoms. Of course, not all flowers or plants require pruning, so it's important to know which ones do. Luckily, Country Living have put together a list of 10 popular plants that need pruning before summer: Ornamental Grass This pluming grass is great at adding visual interest to your garden. To ensure it blooms to its full potential, prune it back by about two-thirds before summer kicks into full gear. Panicle Hydrangea Pruning hydrangeas will encourage fuller, healthier blossoms. Country Living advise to cut it back by about a third and to remove any weak or broken stems. Caryopteris While this plant is known for its gorgeous deep blue blossoms, it can become foliage-heavy if left untrimmed. You can cut them back by about 30 to 45 cm without harming them. Smooth Hydrangea Similar to the panicle variety, smooth hydrangeas should be pruned back by about a third to guarantee fresh, healthy growth and to remove any discoloured or unappealing blossoms. Russian Sage This hardy plant will grow back year after year if cared for properly. To get the best of its summer bloom, you can cut it all the way to the ground to allow fresh new growth to spring back up. Butterfly Bush These beautiful bright purple bushes are so-called because they attract butterflies. To maintain its bloom throughout the summer, Country Living advise to cut most of the plant back once blossoms start emerging. Otherwise, you can deadhead dull blossoms. Rose While roses are generally low maintenance, they will benefit from pruning before the summer hits. Country Living say you should cut them back by about a third "straight across". Lavender Many gardeners enjoy growing lavender for its delicately-scented purple blooms. However, if your plant needs sprucing up, you can prune it back. Though make sure not to cut into the woody stem and not to prune after buds have appeared. Catmint A cat's favourite plant, felines are irresistibly drawn to this flowery bush. It's not necessary to prune before summer but cutting away dead stems will improve its appearance. Boxwood While not absolutely necessary, pruning this evergreen bush can improve its appearance. Country Living write: "You can trim to shape it, or you can leave it more natural-looking and not prune, depending on your preference."

Penstemon I love this plants genus of because most will flower all summer and autumn. They'll grow in sun or semi-shade in a well drained soil and produce a non-stop display of tubular flowers in an array of colours and colour combination to suit all tastes. Luzula sylvatica 'Marginata' With the evergreen leaves edged with yellow it's great asset is that it will grow in sun or shade in any type of soil and is great as groundcover in the hardest spot to fill - dry shade. Eryngium x zabelii 'Big Blue' A stunning, nectar-rich plant that will feed the beneficial insects in your garden. Leave the flowerheads once they have turned brown because they look stunning with winter frost and snow, extending the plant's interest period. Sarcococca hookeriana 'Winter Gem' If you need winter scent then look no further than this compact, evergreen shrub. The scent is stunning and the evergreen leaves create an excellent backdrop for the summer flowers. Cornus sanguinea 'Anny's Winter Orange' A dwarf version of 'Midwinter Fire' the very colourful stems create a stunning winter display, particularly on sunny days. Rosa 'Noisette Carnee' A very well-behaved climbing rose that is perfect for training over an arch, pergola or gazebo. The small, 'noisette' flowers are blush-pink and produce the most amazing clove scent constantly from June to November. Sanguisorba hakusanensis 'Lilac Squirrel' I've never seen a squirrel with a drooping, shaggy lilac tail, but this variety will give your garden an unusual and different look throughout summer. It does need a moisture retentive soil but will grow in sun or semi-shade.
