This evergreen Magnolia grandiflora 'Alta' tree has gloriously shiny leaves with rust-coloured undersides and pure white, goblet-shaped flowers that open late in summer with an intense, sweet, citrusy fragrance. It doesn't like strong winds, but if you have a sheltered plot, then it'll shield you from your neighbours' gaze in style. For a compact garden, choose smaller varieties, such as 'Little Gem'. This Magnolia will grow to eight to 12 metres high with an eight-metre spread.

Firstly, late spring flowering types such as deciduous Clematis Montana or evergreen C. armandii will achieve six to nine metres in height and are good in sun or shade. They're low maintenance and don't need annual pruning. Clematis grows fast, spreading its delicate pink flowers across fencing, providing a nesting place for small birds. By June, you'll have a stunning array of dense blooms. Clematis dies back in the autumn to flower again in spring.

'Stipa tenuissima' always features heavily in gardens at summer flower shows, after which sales go through the roof. A neat, compact Mexican Feather Grass with stiff, thin stems, a strong arching shape, and open structure, it's almost transparent, rather than the dense effect of some other grasses. Also known as ponytails or angel hair, its wispy, pale leaves are topped with fluffy heads of silvery-green flowers from June to September.
Customer review: "Two fine pots of ornamental grasses, arrived in good condition."
Pros
- Natural privacy screen
- Hardy
- Low maintenance
Cons
- Flowers in May, so not one for Hayfever sufferers
| Quantity: | 1, 3 or 7,5 litre |

Best for a Mediterranean vibe
If you're after a dazzling display, a Pelargonium or Geranium is a great choice with its large colourful flower heads. 'Horizon Red' has red leaf zoning and scarlet dome-shaped blooms that'll heat up your hanging basket, perfect for a Mediterranean feel. It features bi-coloured leaves, so even on the rare times there isn't a flower on this plant, its leaves still provide interest. It can be potted up as a windowsill houseplant through winter before replanting outside in a hanging basket in spring. Due to their fast-growing habit, they can become a host for aphids; just pinch off stems with bad cases to promote more flowers.
Customer review: "Excellent plugs, very healthy, now growing very, well packing was spot on, quick delivery. Cheers."
Pros
- Year-round colour and interest
- Versatile
Cons
- Can attract aphids

You can even add Cornflowers to salads, as the petals are edible. Seed bombs make a wonderful gift idea, and there are several mixes available, including poppies.

Best outdoor plant for children
Putting on an amazing display of colour and spectacle between July and September, these Super Giant Sunflower Seeds need to be scattered near a fence so they have a little support as they grow up to 10 feet high. What's more, the seeds and flowers of a Sunflower are edible, so you get a bumper harvest from the pack of 50 seeds. As the name suggests, Sunflowers thrive on the sun, so position them in full sunlight. They grow fast, so you can plant them in pots in spring for a late summer display.
Customer review: "First up you get loads so if you want a giant sunflower forest, you're making a good choice. Planted these out in a propagator on a heated matt (you don't need this but I'm growing a few things from seed this year and had room) within a week I have 100 per cent success rate… very impressed. Large seedlings already growing around 1/2 inch a day."

Best garden and outdoor plant FAQs
What are some mood-boosting and easy-to-care-for garden flowers?
Sunflowers
Sunny, smiley helianthus blooms offer a fabulous source of food. The generously sized centres are made up of hundreds of tiny, tubular flowers to create a feast for butterflies and other pollinators on the perfect landing pad. Painted lady caterpillars sometimes feed on their leaves too. Faff-free sunflowers can be grown from seed, so they're as cheap as chips. Though they come in all sorts of colours, choose yellow as it's thought these are more attractive to pollinating insects.
Young sunflowers tilt their flowerheads to track the sun. This process, known as heliotropism, is thought to help attract pollinators, as many find warm flowers more attractive.
Michaelmas daisies
Asters are stress-free, late summer blooms, and they're really tough and easy to grow. There's a lovely range of colours, including purples and mauves, which seem particularly attractive to butterflies. They bloom right into autumn, providing vital late forage for garden pollinators over winter.
Lavender
Whether it's just a patio pot of a compact variety or a lovely long lavender hedge, this aromatic plant with its fragrant flowers is a must if you want lots of fluttering wings in your plot. The tubular flowers need a long tongue to access the nectar prize, so they're a favourite with butterflies, who can efficiently feed from the clusters of flowers by alighting at the top of each stem.
Begonias
A fantastic choice for beginner gardeners, these bedding plants allow you to get creative and test out new designs each year. Begonias are exceptionally versatile and can be planted in beds, hanging baskets, containers and window boxes. They come in all shapes, sizes and colours and will quickly fill your containers and hanging baskets for a beautiful splash of colour. They are also very affordable and will transform your outdoor space at very little expense.
When should you plant hanging baskets?
You can plant summer hanging baskets from April onwards, but keep them protected from frosts in your greenhouse until the end of May. If you don't have a greenhouse or means of keeping your planter protected, it's best to plant them in early summer when the risk of frost has passed. For winter hanging baskets, plant between September and October.
How many plants do you need in a hanging basket?
As a general rule of thumb, plant specialists recommend using one plant per inch of basket diameter, so for a standard 30cm hanging basket, this would be about 12 plants. The only exception to this is with strong-growing plants such as Fuchsias and Geraniums, where it's best to use five plants per 30cm hanging basket.
How do I look after sunflowers?
Modern Gardens expert Geoff Hodge advises:
Pick healthy plants
You can buy young plants from garden centres and plug plants from mail-order suppliers. Look for compact, bushy plants with a good covering of healthy, well-coloured leaves. Reject anything with lots of dying, off-colour or yellowing leaves. It's also super-easy - and very satisfying - to grow sunflowers from seed. Either sow indoors on a sunny windowsill in small pots in April or sow them directly outside where you want them to grow at the end of April or in early May.
Keep them alive
Sunflowers need a sunny spot and well-drained but water-retentive soil that doesn't dry out in summer. This is easy to achieve by simply digging in plenty of moisture-holding organic material such as Verve Horse Manure Soil Conditioner. In containers, use multipurpose compost.
Help them thrive
Sunflowers will grow and flower more profusely if the soil or compost remains moist, so water thoroughly whenever it starts to dry out. Feed regularly with a high potash liquid fertiliser such as Phostrogen All Purpose Plant Food, following the instructions on the label.
Deadheading the faded blooms will help promote further flowering, but do leave the last of the flowers towards the end of the summer to allow them to set seeds for the birds. Then, in autumn, cut the seed heads right underneath where it join the stem and hang upside down for the birds to enjoy.
