The joys of June!  The month with the longest hours of daylight.  It’s a wonderful time to be out in the garden and here are ten plants that look great at this time of the year and should add summer joy and sparkle to your garden.

1. Lupinus ‘Masterpiece’ (Lupin)

Lupins are the classic cottage garden plant with their majestic spires of brightly coloured flowers, which start to appear just as the last of the spring flowers fade away. This cultivar delights with its rich, burgundy/purple-coloured flowers and looks lovely planted mid-border paired with orange flowered perennials, like geums.

2. Rosa ‘Rosemary Harkness’ (Rose)

This gorgeous, highly scented, bush rose pumps out pretty, apricot, pink-coloured flowers all summer long. And, as a bonus, makes a great cutting rose too!

3. Geranium x magnificum (Hardy geranium)

There are literally hundreds of hardy geranium cultivars to choose from!  They work brilliantly in plant borders as they produce vast numbers of flowers.  And magnificum is indeed magnificent, producing large rich, purple-veined, deep-blue flowers throughout the summer months. Additionally, these grow above mounds of mid-green leaves, which turn bright red during the autumn.

4. Philadelphus ‘Fragrant Falls’ (Mock Orange)

There can surely be no greater highly scented summer shrub than Philadelphus and this cultivar. As the name suggests, this flower produces delicately arching stems covered in clusters of pure white, bell-shaped, super-scented flowers during the early summer months. Its delightful-looking shape makes it an ideal choice as a specimen shrub as well as one for the mixed border.

5. Geum ‘Borisii’ (Avens)

This brightly coloured, deep-orange flowered, herbaceous perennial will continue to sporadically flower well into the autumn after its first flush in early summer.  One of the smaller cultivars available, this is an ideal choice for containers or smaller gardens.

Top Tip

Ensure to deadhead this plant regularly. As this will prolong the flowering period!

6. Sesleria autumnalis (Moor grass)

Easy to grow, evergreen grasses that don’t get too large or self-seed too much are not that common, so Sesleria is the ideal candidate for planting en masse amongst flowering plants. Whilst it is best in partial shade, it will tolerate a wide range of soil types and locations.  It tends to grow more during the autumn and spring, and during the summer months. Also, they send up upright stems of shimmering, silvery-grey, long-lasting flowers.

As the grass is evergreen, it produces year-round. The foliage is grey-green between June and October, and becomes an attractive chartreuse green in the autumn months.

7. Calycanthus ‘Venus’ (Carolina allspice)

This is a real ‘beaut’ of a shrub, producing large, scented flowers that look very much like magnolia flowers. They boast cream-coloured outer petals and dark burgundy inner ones.  Fully hardy and easy to grow if they are sheltered from cold winds.

8. Thalictrum ‘Elin’ (Meadow rue)

Thalictrums are tall, airy, graceful perennials that light up shady parts of the garden for weeks on end and blend beautifully with other plants. ‘Elin’ grows to a great height and needs no staking! Its sprays of lilac flowers are delightful and continue being produced until early autumn.

9. Deutzia x rosea ‘Yuki Cherry Blossom’ (Deutzia)

This extremely beautiful, flowered shrub is unusual in that it grows to just over half a metre tall and wide. And its creamy-white, pink flowers produced during early summer look just like cherry blossom only much lower down to the ground!  The leaves on this low-maintenance plant turn shades of burgundy in the autumn months before falling making it an ideal plant for containers or front of border.

If you’re looking for a long-flowering climber and don’t mind the fact that it’s half-hardy and may not survive the winter unless taken into a conservatory or frost-free greenhouse over winter, then this is the vine for you. And it will flower all the way through the summer right up until October producing hanging flowers of deep, rich purple colour.
