For a florid garden or driveway all summer long, plant Mexican marigolds, surfinias and fresh seedlings. Your choice of ornamental plants will depend on the amount of sunlight you receive. From bulbs to annuals and perennials to cuttings… Here's our advice for getting in bloom.

Flowers to plant straight off

Annual flowers

It's your last chance to get planting those annuals: zinnias, clarkias, marigolds, Mexican marigolds, pheasant's eyes, morning glory, cosmos, lavatera... Sow any cold-sensitive plants in direct warm sunlight. If you haven't already sown your nasturtiums in May, get them in quickly at the start of the month.

Biannuals and perennials, on the other hand, can be sown throughout the month to flower the following spring: forget-me-nots, pansies, lunarias, wallflowers, daisies, hollyhocks, foxgloves… In shadier places, put in your fuschias, New Guinea impatiens, begonias, etc.

In planters or pots

On a balcony or in pots, geraniums and miniature roses can be set down at the start of the month, as well as your annuals: nasturtiums, petunias, surfinias, purslane, zinnias… In larger planters located in shadier areas, begonias, balsam and ornamental leafy plants: alumroot, coleus, mint.

Planting bulbs for summer

It's also a great time to dig in your summer-flowering bulbs, some of which might last you through to the autumn: dahlias, gladioli, crocosmia, canna lilies, crocuses... These are brilliant for decorating the beds and borders in your garden as well as planters and pots.

One plant grown from bulbs that has attained great popularity with gardeners is the dahlia, whose magnificent flowers come in a wide variety of colourings. Planted in June in a sunny area, dahlias will flower throughout autumn, provided it doesn't get too cold.

A great way to add colour to a patch of damp ground or the banks of a pond is with arums. Remember to remove any wilted foliage from the flowered bulbs and separate out your daylilies, crocosmias, autumn crocuses and colchicum.

Using cuttings to expand your garden for nothing

To make your plants go further for no extra cost, think about taking cuttings. June is the perfect time to take cuttings from shrubs (hydrangea, clematis, ceanothus, jasmine, Japanese quince, escallonia, passionflower...) as well as perennials (chrysanthemums, asters, carnations, anthemis, galliardia etc.).
Take a 15cm length of an annual stem (or primocane) without flowers. Remove all the leaves apart from the top two, which should be cut down halfway if the leaves are large, to limit water loss. Bury the cutting up to halfway in a soft, sandy substrate (half loam, half sand), and place in a shaded area.

Beautiful flowering shrubs

Although you might associate shrubs more with late autumn, the varieties sold in pots can be planted as early as June. Many will be flowering at this point, which gives you the advantage of being able to choose your shrubs on the spur of the moment according to the appearance of the flowers. Don't forget to consider flowering duration as well though, often held to be the hallmark of a good shrub.

Some shrubs really benefit from being trained into open hedges: ceanothus, flowering redcurrant, abelia, lilac; while others are better adapted to cultivation in trays or even indoors: anisodontea capensis, gardenia, cuphea etc.

Shrubs can be handy for beautifying a wall, fence or trellis: aristolochia, trumpet vines, climbing hydrangea. Hygdrangeas can tolerate shade, while the best thing for a south-facing wall is a bougainvillea.

When I was young, I was already working in the family garden. Perhaps that is where my interest in plants and gardening came from. So, it was logical for me to study both plant biology and agronomy.   At the request of various publishers I have, over twenty-five years, written many books on the subject of plants and mushrooms (a subject that is close to my heart).They were mostly identification guides at first, but shortly after they were about gardening, thus renewing the first passion of my childhood.   I have also regularly collaborated with several magazines specializing in the field of gardening or more generally in nature. There is no gardener without a garden, I have cultivated mine in a small corner of Cambridge for the last thirty years and this is where I put into practice the methods of cultivation that will I advise you in as well.
