Ten plants that coped with the drought

Following on from my last post, in which I showed which plants had withered and died in the extreme drought conditions of the summer just gone, here are the ones that survived (and in some cases, thrived).

  1. Ceratostigma
    I’m not entirely sure on the variety (it’s probably C. willmottianum) as this pre-dates our arrival in the garden. We’ve split and moved it around the garden freely. It’s a lovely ground cover plant with glossy, deep green leaves and strikingly blue flowers in mid to late summer (this photo was taken in August). While other plants shrivelled due to lack of moisture, this coped admirably.

2. Cornus alba ‘Sibirica’
We’ve got a few plants of this, and they’re cuttings of cuttings – it strikes easily, and layers easily too. Its root system is quite extensive, which could explain why it wasn’t overly troubled by the drought.

3. Fig
No big surprise here, as fig is known to thrive in poor, dry soil. This is the standard ‘Brown Turkey’ variety. Although it’s growing well, in full sun, and as recommended, I attempted to restrict the roots by enclosing them with a cage of paving stones, it hasn’t produced any fruit for us yet. I took this photo after I’d pruned and tied in the stems – the growth was very lush prior to this.

4. Iris sibirica
The Siberian irises just seem to go from strength to strength here. I initially put them by the pond, in what was supposed to be a bog garden. But the clumps bulk up quickly, and I’ve split them and moved it all around the garden. It flowers in June, so had done its stuff before the drought had been dragging on, but the leaves died down no more quickly than they would do in a ‘normal’ year. Iris sibirica is generally advised to be a plant that loves (and needs) moisture. But of course, plants don’t read the text books. By August the flowers were long gone, but you can see the leaves are still fine. The flower stems turn brown and stand strong throughout the winter, giving what us pretentious garden designers like to call ‘architectural interest’.

5. Day Lilies
Day Lilies have been a revelation to me. I hadn’t seen too much of them until we arrived here. I moved them, somewhat carelessly, not being that bothered whether they survived or not, but they both survived and spread, and I’ve come to love them. The flowers are very attractive, and also edible – they look great on a salad. The varieties in our garden have only a limited flowering period, but the day lily season is eagerly awaited. Apparently the newer varieties flower for much longer. The photo is of my favourite (here at the tail end of its flowering), which I think may be ‘Stafford’. Day lilies appear to be bullet proof, muscling their way through on any soil, in any conditions. We will plant more!

6.Stipa tenuissima
Apparently this has been renamed as Nassella tenuissima, by those great friends of the gardener (!) botanists. The name suggests it might like a hot, dry climate, and it does. It seeds prolifically in our thin, sandy soil, and had no issues with the drought. You need to keep on top of the seedlings, but it is a pretty plant that looks good all year round, moves in the breeze, and works well as a background or companion to so many perennials.

Another stipa – Stipa gigantea – has been equally resilient.

7. Physocarpus ‘Diabolo’
I love this dark-leaved physocarpus, which has clusters of small white flowers with rich red surrounds. It has taken to our soil and grown well. By the end of the summer it was looking a little tired, but undaunted.

8. Skimmia
Another shrub that was in the garden when we arrived. Not one of my favourites, but it survived a move that was necessarily brutual (it was rather big to move at the time) and flourished. It does get shade until mid to late afternoon, which will have helped, but this glossy-leaved evergreen came through the drought with no obvious ill effects.

It’s turned out to be a bigger variety than I’d guessed it to be, so I’ve moved it again, this time to the back of the border. Let’s hope it survives.

And the last two are plants that might not surprise you…

9. Salvias
These are the type that are not always entirely hardy. But despite our living in a cold, windy area (thanks to the desolate, tree-less landscape created by the ‘custodians of the countryside’) the bright red Salvia ‘Royal Bumble’ has come through the last four winters. We added Salvia ‘Nachtvlinder’, which is similar, but with dusky purple flowers – less showy than S.’Amistad’, but you don’t have to buy it new every year. They need trimming back now and then, but will flower from June until autumn. We’ve acquired some other, similar varieties this year. This bright, sub-shrub could be one of the answers to the question of what we fill our garden with if the summers continue to be very dry – it is happy in our light soil, and copes well with low rainfall.

10. Sedum
The succulent leaves give this plant a mechanism for living for long periods without much moisture. Did I say sedum? I meant Hylotelephium of course (another botanist curve-ball!) The first is a dark-leaved variety called Xenon, from a cutting I was given when I volunteered at Dyffryn gardens in South Wales.

An extra to the ten is a plant that I grew from seed a few years ago. Datura metaloides is a highly fragrant, tender plant with large white trumpets, which is related to the highly prized Brugmansia. In fact, some sources suggest the two are one and the same species, with the sole difference being that Datura holds its flowers upright, while in Brumansia they hang down. Both are highly poisonous (reading between the lines, I think they mean hallucinogenic, but apparently people have died trying this out for themselves, so not recommended). The leaves and flowers are greasy – I would recommend you don’t lick your fingers after touching it (best wear gloves). But anyway, it seeds prolifically (from large spikey seed capsules that could double as a mace) and the seeds stay in the soil and germinate freely in late spring/early summer.

I moved some of the seedlings that came up, and they struggled somewhat (though they came through in the end). Those that were allowed to grow without disturbance flourished, and were apparently able to grow big and lush, and produce lots of huge flowers, regardless of the lack of rain (and we didn’t water them at all either). So if you want an annual that grows itself, and needs no input from the gardener, you could try Datura (if you dare…)

In truth, despite the sad state of the garden during this year’s drought, there were a surprising number of plants that did quite well. I could have included Gaura (sorry; Oenothera!), evergreen Euonymus and Calamagrostis ‘Overdam’. Though the garden was badly hit by the drought, more plants came through successfully than didn’t (and those that died will probably come back next year). So it wasn’t as bad as all that. All the same, if we get more years like the one just gone, changes will need to be made, and we’ll need to re-stock the garden with plants that will thrive in the new conditions. From experience in my garden, top of my list will be day lilies, grasses (particularly stipas), salvias, sedum and physocarpus.

I wish you all a happy horticultural 2026

10 Plants that struggled in the drought

After a string of dry years, this spring and summer were the driest yet. And although we didn’t have the record high temperatures seen a few years ago, it was still hot, with more sunshine than we’re used to, and drying winds that stressed plants further still.

As if that wasn’t bad enough, I’m gardening on thin, free-draining, sandy soil, which loses its moisture very quickly. So which plants failed to cope with these exceptional (or perhaps, no longer exceptional) conditions?

  1. Viburnum (Viburnum plicatum f. tomentosum ‘Mariesii)
    This is a glorious shrub, with fresh green leaves, a tiered branching habit, and branches smothered in clusters of bright, white flowers in late spring. Under normal conditions it’s dense and bushy, filling a large space. This year, by early August it had shrunk back, lost quite a few of its leaves, and those that remained hung down limply.

2. Phlox
This is Phlox ‘Peacock White’. Phlox prefer moist soil, so it’s no surprise this struggled, as it has done most years. You can see it’s trying to flower, but the flowers didn’t come to much.

3. Clerodendron trichotomum
A slightly rare shrub with white flowers and very striking berries, this too should have been full and lush. Shortly after I took this photo it went into early dormancy – we’ll have to see whether it comes back to life next spring.

4. Corylus maxima ‘purpurea’
A vigorous (normally!) large shrub with large, dark leaves. By early summer it was obviously suffering. This year it hardly put on any growth, and looked sick from early summer onwards.

5. Ligularia
Ligularia dentata ‘Midnight Lady’. This too is a moisture loving perennial. I planted it by the pond, in a bed with a pond liner beneath, to create a bog garden. Unfortunately the pond all but dried up, and the pierced liner beneath these plants couldn’t hold onto the moisture. The ligularias did eventually produce some flowers, but they didn’t hold up. The leaves would be expected to be large and lush.

This is what it should look like (as you can see, slugs and snails love the big leaves)…

6. Hydrangea (H. paniculata ‘Limelight’)
I have one large plant, and a few smaller ones, struck as cuttings. Hydrangeas are not known for their drought tolerance either, so perhaps not such a good choice. Having said that, planted in shade, it has been reasonably resilient. Until this year, at least. This photo too was taken in August.

7. Cornus kousa
A large shrub/small tree, grown largely for its showy white flowers (which are actually bracts – the flowers are tiny) followed by strawberry-like berries. Last year it only produced a handful of flowers. This year there were none, and the plant sulked from shortly after the buds broke. I’m wondering if there’s more to this than a lack of water. We do have honey fungus in the garden, so it could be this cornus is under attack.

8. Persicaria ‘Purple Fantasy’
Oh Dear! No amount of watering was going to save this rather vulnerable perennial. It puts up shoots early, which tend to need protection from the frost (unfortunately I didn’t get around to fleecing it). It’s first shoots were hit by frost. It sent out new shoots, but they too were killed off, by a late frost. It recovered again, but by August, despite attempts to keep them watered, all of the plants had shrivelled and died.
On the plus side, I split up some of the clumps and replanted them in shade, and with the wet autumn they put out some new growth, so there’s hope for next year. Here is one I moved (taken yesterday).

9. Aconitum
The flowers were poor, and the foliage withered before the flowers had finished. The late flowering ‘Carmichaelii’ varieties weren’t much better either.

10. Roses.
I’m beginning to wonder if it’s worth continuing to grow the traditional bush varieties in an open border. Rosa ‘Wollerton Old Hall’, a climber planted against a north-facing wall, did okay, as did Rosa ‘Clare Austen’ (planted against a shed, again facing north). ‘Dame Judi Dench’ (pictured), ‘Munstead Wood’, ‘Tuscany Superb’, and even ‘Gertrude Jekyll’ were sick specimens this year. On a pergola, ‘Constance Spry’ and ‘Lady of the Lake’ fared little better.

The flash of red behind gives a clue to the plants that coped well with the dry season.

In the summer, we did as much watering as we could. The four water butts ran out early on. I’ve been holding off, but I think it might be time to re-evaluate my planting plan. The problem is, of course, that if we switch to plants that like a Mediterranean climate, and then we get a few cooler, drier summers (because despite climate change, these things do go in cycles), we could find ourselves with the reverse of what we have now. I.e.; plants curling up and dying because it’s too wet and cloudy. Ideally we need plants that will cope with wet or dry, hot and cold – if such plants exist (actually, I think they do).

In my next post, I’ll highlight the plants that came through the drought unscathed…
