Chris Bonnett is the founder and CEO of Express Gardening

If your garden is looking really sad and scorched after the last few days of hot weather, it might be time to consider some new plant choices in your garden – plants that will not only survive, but thrive in dry conditions. , warm and sunny. They will need watering when freshly planted until they are established, but once they have roots in your own soil they can take a lot of neglect and just about any weather. which are inflicted on them. It’s not just arid desert plants and palm trees either – there are even flowers that will grow in harsh conditions. Being in Britain, we’ll also need plants that can withstand the weather at the other end of the thermometer when temperatures also drop – so I’ve picked out six of the best below.

The best warm weather plants to sow in your garden right now

Mediterranean Palm – Chamaerops humilis (heat tolerance rating 10/10)

In its natural habitat, this palm is naturally found as far north as the French coast, but throughout the Mediterranean in what could be considered typical tourist hotspots. You may have seen it during your holidays, and it is certain that you have even just grown up on the side of the roads on the Côte d’Azur and the French Riviera.

All of this means that it will handle the intense heat with ease, while still being comfortable when temperatures dip down to -13°C in the winter.

The Mediterranean fan palm can be used as a beautiful specimen plant on its own or combined with a number of tropical and jungle-style plants. Maybe you want to go for the minimalist Mediterranean look combining the plant with olive trees for example. Unpruned it develops into an attractive shrubby form, with occasional pruning it will become a single-trunked tree.

Both options provide an architectural element in any garden setting. It’s also great in a container for a patio, deck or balcony – and will forgive you if you forget to water that pot once in a while.

Ornamental Sage – Salvia nemorosa – (9/10 Heat Tolerance Rating)

There is a huge range of salvias to choose from, including the famous sage herb. For ornamental purposes, how about the nemorosa type, ‘Caradonna’ with midnight blue-violet flowers or ‘Rose Queen’ with pale pink flowers.

These will thrive in poorer, well-drained soils which are often a real challenge, they will flower from late June through summer and into autumn. You can top the spent stems to encourage the plants to vomit even more, but they will only reach 60-80cm in height so will do well in any garden border.

In winter they migrate to a clump at ground level (not surprising when they are known to tolerate temperatures as low as -40°C) only to reappear each spring and start all over again as they easily tolerate temperatures in the 30+ years.

Tree Hollyhock – Hibiscus syriacus – (Heat Tolerance Index 9.5/10)

With blue, white, pink and purple flower options, as well as combinations of all of these forms, as well as double-flowered forms, there’s a lot to love about Hibiscus – yet they remain underutilized in gardens and UK landscapes.

Hopefully the weather we had is changing. They are very easy to grow and low maintenance, requiring absolutely no attention, and to top it all off, are one of the most prolific flowering shrubs from mid to late summer through summer. fall.

They will make beautiful, sturdy, upright ‘hollyhock’ shrubs with bright green leaves that will thrive when many other shrubs look tired, so they’re really great for continuing displays from mid-summer onwards.

Try the ‘Marina’ variety for trumpet-shaped blue blooms with a darker center, or perhaps the ‘Pink Chiffon’ flower puff for pastel pink blooms that look like a ruffled silk blouse. Fully hardy down to -18°C, so there are no winter worries. Give Hibiscus a sunny, well-drained spot.

Allium senescens Millenium (heat tolerance rating 10/10)

It may now be my favorite Allium – not for its size, but for its flower power and its continuous flowering all summer long. I have grown this one since 2005 in my own garden so it has certainly stood the test of time with me and has now gained wider fame in recent years through the horticultural trade – they sell it as “Millennium “, around the time I first grew the plant and started the Gardening Express nursery – so it’s very fitting.

There are a large chunk of these plants thriving in the 40 degree heat outside my office as I write this column, all in bloom, and I know we can enjoy this skeptic at least until in September their fleshy leaves show no signs of wilting in the Chauffer.

It has proven to be a very well bred plant and offers great value and interesting flowering for weeks into the summer. It is also very attractive to bees and butterflies. Forming a tight clump, it will shoot up numerous strong stems about 60cm each and topped with a head of soft pink-purple flowers.

Alliums are the unsung heroes of every Chelsea flower show in recent memory, but with millennia the flowers continue to come and go over a very long period, months, in fact, which deserves a place in n’ any garden.

It’s even perfectly edible like other Alliums, and can be used as an interesting addition to your summer salads or a stir-fry! I’m told it can handle -35c, but I haven’t put that to the test – so I’ll play it safe and advise -20 in winter, which should cover the whole of the UK.

Senecio Angel Wings (7/10 Heat Tolerance Rating)

There is something quite spectacular about the appearance of this plant, you can really see how it got the name angel wings. It’s not the hardiest in winter, only tolerating around -5c, but summer is no problem for it.

The attraction here is the leaves in the shape of angel wings, they are very unusual and eye-catching, huge and silver-grey-white, each with a soft velvety texture – people find them irresistible to the touch. An evergreen perennial, it will very rarely produce a few yellow flowers, but this one is all about the foliage.

Angel wings are native to the Patagonia region of Chile in South America, near the coast, which means if you have a coastal garden, it’s a great choice thanks to its tolerance to salty winds. It is a beauty but may be short lived if we have very humid weather so perhaps grow in a pot and move to a sheltered area for the winter if you can.

Torbay Palm – Cordyline australis (heat tolerance rating 8/10)

Cordylines are very structured, resistant and robust. They will form an attractive plant with long, sword-shaped leaves from the top down a central stem, making this a most unusual specimen plant, forming a trunk over the years.

Architectural in appearance, this extraordinary plant is ideal for patio containers or a balcony.

It is hardy and likes to grow in a sunny position on well-drained soil. Best of all, you can get them in fresh green, variegated, pink, and crimson-burgundy.

All will form a trunk over time, so you can get a fully mature palm on your balcony or patio, thriving in the heat, winter temperatures here are -7 for pinks and lower for greens and reds. Ideal specimens for a jungle or tropical themed garden.
