I'm rather a no-nonsense kind of gardener. I love working in my garden, weeding, digging, pruning and deadheading.

But I admit that I don't have patience for plants that need babying. You've got to be tough to earn a spot in my garden – and even tougher to stay around year after year.

As a garden writer, I also have the privilege of trialling many new annuals, perennials and shrubs every year, which allows me to learn what can stand up to nature's whims. From freezing temperatures to blazing heat and humidity to weeks without rain, I've seen what plants can take abuse and still thrive, and I do admit to having a few favourites.

I'm also not wishy-washy about what has to be done – plant got too big? Time to transplant you, and hopefully, you’ll survive the move even if it's midsummer. Too gangly? It's time for a rejuvenation prune. I love plants, but every one of them needs to bring beauty and joy to my garden, to support pollinators and to be resilient enough to survive real-world conditions.

Ahead, here are the toughest garden plants I've ever grown and why they deserve a spot in your garden.

1

Hardy geraniums

This low-growing groundcover, also known as cranesbill, has elegant flowers that float above its foliage in late spring to early summer. Hardy geraniums grow in all sorts of soils and conditions. I started with one plant more than a decade ago and have since transplanted pieces throughout my garden.

Lilac

Lilacs can live for decades, but many become ginormous and overwhelm a space. I fell in love with a reblooming type, 'Bloomerang Dwarf Purple', a variety that keeps a nicely mounded three-by-five-foot shape.

It even survived a mid-season move due to a reno project. Now, that’s a tough plant!

Sweet Alyssum

This honey-scented, low-growing annual is a delightful plant that attracts tons of beneficial insects to my garden. It's gorgeous when spilling out of window boxes and mixed planters.

My favourite cultivar is ‘Snow Princess’, which blooms non-stop until a hard freeze. It's often one of the last annuals to survive well into late autumn.

Russian sage

For hot, dry areas of your garden, you can't beat Russian sage. This perennial has willowy, silvery foliage that's covered in tiny bright blue flowers. The effect is ethereal when planted in drifts. ‘Denim ‘n Lace’ is my favourite cultivar.

Sedum

Sedum, also known as stonecrop, is a succulent, so it’s drought-tolerant. It provides beautiful late-season colour and food for pollinators. Mine is always covered in honeybees in late August and September.

Many new cultivars have been introduced, but ‘Autumn Joy’ is an old favourite that still delivers, while ‘Brilliant’ has more intensely pink flowers on sturdy stems.

Hellebore

Hellebores are late winter to early spring bloomers that really need very little care. Their exquisite blooms also make excellent cut flowers. Though this perennial is slow to take off and took about five seasons before it really showed off in my garden, it's been worth the wait.

Dead-nettles, also known as lamium, are an underappreciated groundcover. With silvery-green foliage and pretty pink, purple or white flowers, it adds splashes of colour to shady locations, though it can take some morning sun. This perennial is a fast grower but won’t take over your garden. I’ve grown many types but especially like ‘Pink Chablis’.

Sweet potato vine

This vigorous annual vine comes in colours ranging from chartreuse to deepest burgundy. It looks beautiful tumbling out of planters or window boxes and doesn't fade one bit in the heat. It's equally happy in shade or sun. I prefer to plant it solo in pots because it will crowd out other plants in a container.

Catmint

catmint nepeta racemosa 'walker's low'. nepeta is a genus of about 250 species of flowering plants in the family lamiaceae. the members of this group are known as catnip or catmint because of their famous effect on cats nepeta pleasantly stimulates cats' pheromonic receptors, typically resulting in temporary euphoria. it can also induce mild euphoria in humans. the genus is native to europe, asia and africa. it is now also common in north america. most of the species are herbaceous perennial plants, but some are annuals. they have sturdy stems with opposite heart shaped, green to grayish green leaves. the flowers are white, blue, pink or lilac and occur in several clusters toward the tip of the stems. the flowers are tubular and spotted with tiny purple dots. image is captured in 12 bit raw and processed in adobe rgb color space.

Catmint is virtually indestructible. Heat- and drought-tolerant, this sun-loving perennial has silvery-green foliage and tonnes of purple flower spikes that bloom for months. It also attracts pollinators. I love ‘Purrsian Blue’ for its dark purple-blue flowers and ‘Picture Purrfect’ for its earlier bloom time.

10

Panicled hydrangea

I love hydrangeas and have about 25 different varieties in my garden. But the most carefree type is the panicle hydrangea. They’re equally tolerant of cold and heat, and because they bloom on new wood, you won’t lose this year’s blooms, even if you had a harsh winter. My favourites include ‘Bobo’, ‘Quick Fire’ and ‘Little Lime.’
