If you’re looking for a wonderful shade plant to add colour and interest to the darker corners of your garden, look no further than heuchera. This hardy native of North America can withstand the cold, offers a wide range of colourful foliage all year round, and wispy flowers on long stems in the spring. Also known as coral bells or alumroot, this evergreen perennial is a must, and as an autumn bedding plant, is hard to beat. Here’s how to grow and care for it.

About heuchera

Heuchera comes in a variety of colours – ideal for any planting colour scheme.

Heuchera grows in a wide variety of habitats in its native North America, from the salty shores of California to arid Arizona and New Mexico. It likes shade and semi-shade best, but some varieties will grow in full sun. It’s not particularly fussy about soil type either, although it doesn’t like to get too wet or too dry..

Growing from a crown at ground level, the foliage is this plant’s main attraction. Think purples, red, and burnt umbers at one end of the spectrum, and limes, yellows, and greens at the other, with every kind of variegation you could possibly wish for.

Firm favourites

Heuchera ‘Berry Smoothie’ is a real treat. With its pink leaves and claret veins, it offers a vibrant splash of colour which only deepens as the foliage darkens through late summer and into autumn and winter. Come the spring, you’ll find this plant’s creamy white flowers a delight and a true contrast against the bright leaves.

Fancy something to suit with a verdant palette? Take a look at this Heuchera/ Tiarella hybrid, ‘Solar Power’. With its evergreen yellow lime foliage mottled with dark red markings, it’s a great way to liven up a shady border.

For more subtle coverage of difficult spots, give Heuchera ‘Stormy Seas’ a try. This hardy perennial features maroon and green leaves with silver variegation and creamy white flowers which bloom on tall spikes during the summer.

Where to plant heuchera

Heuchera is a shade-loving plant, but with so many varieties to choose from, there is considerable variation in terms of how much sunlight different specimens can cope with. As a rule of thumb, the colour of the leaves gives you a good clue as to where to site your plant; darker leaves are better at withstanding the sun’s rays.

A great plant for those who garden in coastal areas where salt-laden winds are an issue, the only thing heuchera really doesn’t like is heavy, wet ground which causes the crown to rot, or very sandy soils which can quickly dry out. Improve your soil by adding plenty of organic matter, choose well-drained soil, and water regularly but sparingly.

When to plant heuchera

You can plant heuchera any time the soil’s not waterlogged or frozen, but for best results, put yours in the ground during the spring or early autumn to allow it to establish without risk of frost damage. Dig a hole about twice the size of the root ball and add a handful of organic matter or blood, fish, and bone to give your plant a good start.

Remove your heuchera from its pot and gently massage the roots to separate them before planting and covering until the soil reaches the same level as it did in the pot. Avoid covering the crown itself or there’s a chance it will rot.

How to prune heuchera

After a couple of years your heuchera may start to become rather clumped and leggy. When you part the leaves, you’ll discover woody stems that lead back to the crown of the plant. To prune, cut the stems back to a just above buds of fresh growth at the top of the crown.

To propagate your cuttings, snip away any dead wood until you come to the sappy part of the stem before planting in potting compost; general purpose compost with added grit and a slow release fertiliser will also work. Roots will develop in three to four weeks.

Heuchera rust

Ensure you don’t introduce infected Heuchera plants into your garden.

Although it’s a tough plant, in recent years, the fungal disease, Puccinia heuchera, otherwise known as heuchera rust has become widespread in the UK. It’s a particular problem during wet summers and appears mainly as sunken spots on the top of leaves with orange rust coloured pustules on the underside.

If you’re buying new plants to supplement other, uninfected, heuchera in your garden, it’s a good idea to quarantine the new plants for three to four weeks to be sure they are unaffected. Check your plants regularly for signs of the disease, removing any affected material and destroy rather than compost it.

Because heuchera rust likes damp conditions, pay close attention to soil drainage, plant your heuchera where there’s plenty of air circulation, and water early in the morning so the leaf surfaces have a chance to dry during the day.

You can’t beat heuchera for glorious foliage which provides both vibrant colour and structure to your autumn planting scheme.

Autumn Pumpkin Festival

Twins reclaim throne as Pumpkin Kings with 2,252lb record breaker

Ian and Stuart Paton UK record holders with Paul Hansord, Thompson & Morgan

Hampshire brothers smash the British record and set their sights on the world record in 2017

Ian and Stuart Paton have broken the British record for a giant pumpkin for an incredible 7th time at the annual Autumn Pumpkin Festival in Southampton. The event draws pumpkin growers from across the UK, all hoping to take home the prize for the UK’s largest pumpkin. This year, the Paton’s gargantuan gourd measured more than 19ft in circumference and during its peak period of growth, it piled on a staggering 57lb each day for 2 weeks. To match its rate of growth, the vigilant horticultural siblings, who run Pine Tops Nursery in Hants, lovingly supplied over 100 gallons of water a day, plus a nutrient-rich fertiliser. As the all-important weigh-in date approached, Ian and Stuart were spending 5 hours a day nurturing the 3 giant pumpkins that they entered into the competition. The final weight of the winning entry is just 71lb off the world record.

The new UK heaviest pumpkin record holder

Each time a record is broken at the annual Jubilee Sailing Trust Autumn Pumpkin Festival, show sponsor – seed and plant mail order specialist Thompson & Morgan – takes the winning specimen back to its Ipswich HQ. The seeds are harvested, tested for viability and prepared for sale, so for any budding giant pumpkin growers inspired by this weekend’s jumbo entries, Thompson & Morgan sell the seeds under the aptly named variety, Pumpkin ‘Paton Twins Giant’. It’s a popular line with amateur growers at just £9.99 for two huge seeds with the genetics to become a record breaker with the right care. It’s the seed of choice for serious competitors too – the majority of entries to this year’s official weigh-in at the Southampton pumpkin event were grown from seeds supplied by the Patons.
The brothers will be using seeds from this year’s crop next year – which they say will bear the best seeds in the country thanks to careful hand pollination of their plants to cross two of their best ever performing plants. And with the world record now held closer to home (Swiss gardener, Ben Meier, took the title in 2014 with a 2,323lb monster) they say they are even more set on achieving the accolade themselves.

Stuart said: “We’ve always been confident of winning the world title eventually, and our new greenhouse has made a big difference with its better soil and light levels, an improved watering system and a larger growing area with a more consistent temperature. We’re well prepared to take on not only the Swiss, but the Americans too.”

T&M Horticultural Director, Paul Hansord said: “It used to be said that the world record would never leave the US, but if the Swiss can do it, so can we. Our seed quality just keeps getting better, thanks to the Patons’ selective pollination, and UK growers are upping the game every year. I’ve every confidence the Paton boys can bring the world title to UK shores in the near future.”

Having just handed over the £1,000 prize cheque and with a promise to pay £10,000 for a British world beater, he could be regretting that confidence in coming years!

incredicompost® rated best on the market!

Independent trials carried out by consumer group Which? Gardening have named incredicompost® as the best compost on the market. It was given an overall test score of 95 per cent, setting it well ahead of the next best performer, Verve multipurpose compost (B&Q) at 80 per cent. It came miles ahead of the worst performer – GroSure Peat-Free All-Purpose Compost with 4 Month Feed, labelled a ‘Don’t Buy’ product by Which? Gardening, having scored just 33 per cent in the trials.


We knew we were on to a winner with our first move into the compost market. Our aim with incredicompost® has been to develop a premium-quality product that brings consistency and reliability back to the compost market – something that has been missing since the increased use of green waste materials in many well-known brands, in a bid to reduce their peat content. Gardeners are keen to reduce their peat use but many have reported poor results with existing green-waste products.

incredicompost® addresses these consumer concerns. To reduce the peat in our blend we have instead included wood fibre, sourced from Irish saw mills, actually making use of a surplus by-product. This wood fibre is graded by chip size, so each time we make a new batch we can guarantee consistency from our ingredients, leading to consistent performance from the compost.


incredicompost® comes packed with trace elements and minerals and like many other products includes wetting agent for easy watering, plus a little pre-mixed fertiliser to ensure good early growth. What sets it out from the crowd is a pre-packed sachet of incredibloom® in every bag for mixing in at planting time, ensuring strong healthy growth for 7+ months – a little goes a long way! Separating the feed into a sachet prevents degradation (leading to a lack of nutrients for plants), a common problem with other pre-mixed, long lasting composts.

You can read the full Which? compost trial report in the Jan/Feb 2016 issue.
