Best crocosmia varieties – 16 gorgeous types of montbretia to add fiery flowers add exotic elegance to your yard

With so many dynamic crocosmia varieties to choose from, it can be hard to know where to start. Indeed, crocosmias have undergone a dramatic transformation. Once known as montbretia, there were only a few breeds and they struggled to stand out from the crowd. Now, these vibrant border perennials have gained significant interest in color, size and planting options. Grown from crocus-like corms, wiry stems emerge in summer, carrying long sprays of starry or trumpet-shaped flowers. Each is a little like a lily flower, but held in elegant sprays.

Modern breeding has transformed the fortunes of this enduring bloom. While the original orange and yellow montbretia (Crocosmia x crocosmiiflora) had a reputation for being a nuisance as it spread, modern crocosmias are better behaved – and capable of more enticing and manageable displays. Positioned at backs of borders to complement other exotics, given center stage in fiery flower bed ideas, or allowed to grow as specimens in planters, there’s a crocosmia for every garden.

These days, most types of crocosmia spread less and tend to grow more tightly in clumps. They have larger flowers, and develop more of them over a longer period. Some are also great as cutting garden flowers. According to the American Horticultural Society (AHS), crocosmia are reliable, bold plants that bring a blaze of color to the border. 'As well as vibrant flowers in late summer, they are also useful in the garden because of their attractive upright foliage, producing sheaves of green,' says the AHS. So what are you waiting for? It’s time to add a touch of exotic elegance to your garden with these dazzling crocosmia varieties.

16 striking crocosmia varieties

While the color palette for different types of crocosmia tends to be on the fiery side, there is still a lot of choice and many breeds are stunning. From deepest scarlet through every shade of flame to soft gold, there are also some delightful bicolored varieties and some with bold mahogany markings. These are popular with hummingbirds. A few also have attractive seed heads, while in others the foliage is a lovely shade of coppery bronze.

Here, we have rounded up 16 of the best crocosmia varieties for garden borders, container gardens and the cutting garden, from diminutive bloomers to more dramatic foliage-heavy choices.

1. ‘Carmin Brilliant’

• Hardiness: US hardiness zone 8
• Height: 26-30in
• Best for: Planters

‘Carmin Brilliant’ is one of the most reliable crocosmia for mid and late summer. With soft red flowers, featuring a yellow throat and developing scarlet tones on the backs, this crocosmia is ideal for large summer container planting and mixed borders.

This tolerant variety is happy in less than ideal conditions, but prefers plenty of sun, rich soil and moist soil all summer. Partner with sun-loving heuchera varieties with harmonious foliage like ‘Citronelle’ or ‘Marmalade’.

'Orange Pekoe' (from Burpee) is a similar alternative, perfect for container planting.

2. ‘Emberglow’

• Hardiness: US hardiness zone 7
• Height: 30-36in
• Best for: Cutting gardens

This crocosmia has deep red tubular flowers on green stems through boldly pleated foliage. Ideal for the border, the cutting garden and collectors of dried flowers, ‘Emberglow’ is one of the most striking crocosmia varieties.

These deep red bloomers look especially pretty in front of the purple foliage of cotinus or physocarpus. After flowering, this crocosmia develops into attractive long-lasting seedheads. For this reason, these are plants you shouldn't deadhead. Instead, wait until the seedheads have developed and then cut for drying.

Use essential pruning tools to cut your crocosmia, like these pruning snips from Amazon.

3. ‘Castle Ward Late’

• Hardiness: US hardiness zone 8
• Height: 3-4ft
• Best for: Tropical borders

This is one of the later crocosmia varieties, taller than almost all other crocosmias and possessing slightly pleated leaves. ‘Castle Ward Late’ has relatively small trumpet-shaped, orange-red flowers, which open in generous numbers on arching stems.

Ideal for borders, this crocosmia develops more slowly than other varieties, so plant a little closer together. It looks superb with the bold foliage and large flowers of tropical plants such as cannas, particularly the bronze-purple leaves of ‘Wyoming’.

Perhaps the most popular of all crocosmias, ‘Lucifer’ is tall and dramatic. Huge numbers of large, deep red flowers stand up from the branched arching stems amongst bold, pleated foliage. This variety is ideal for borders, cutting fresh and cutting dried.

It can be vigorous, so be prepared to lift, divide and replant every two or three years to create impact in the right spot. These flowers work well with low ground cover such as Geranium Rozanne (‘Gerwat’). Alternatively, salvia lovers can partner with the upright ‘Blue Spire’.

• Hardiness: US hardiness zone 7
• Height: 28-30in
• Best for: Dahlias

One of the most spectacular varieties, ‘Star of the East’ has huge 4in golden orange flowers. These flowers are a sharp yellow in the throat, held in full view above the foliage, and they face outwards so they show themselves off well.

Particularly beautiful as part of bold groups in mixed borders, they are later-flowering than many varieties so are ideal with different types of dahlias and chrysanthemums. They are naturally strong and steady in growth, but are best not overcrowded so the flowers stay in full view.

Moist conditions (without soggy soil) will encourage a long flowering season and help discourage pest problems. Lovers of red hot poker varieties will find that this crocosmia partners well with kniphofias that have apricot tints. Look for ‘Bees Sunset’, ‘Jenny Bloom’ or ‘Flemenco' (from Nature Hills).

Leave in place without regular division to make a prolific clump, only lifting, dividing and replanting if flowering tails off. Scatter seed of blue-flowered Nigella ‘Miss Jekyll’ (from Amazon) around them in spring for a delightful late summer combination.

10. Bright Eyes (‘Walbreyes’)

• Hardiness: US hardiness zone 7
• Height: 18-24in

This is one of the best choices for planters as well as mixed borders. For anyone who loves to grow dahlias, this crocosmia partners well with bronze-leaved dahlias with flowers in equally fiery shades.

It’s ideal for dramatic garden border planting ideas, planters and fronts of borders. Flowering prolifically, it has enormous impact so avoid blocking its view. Partner with dark-leaved heliopsis such as ‘Burning Hearts,' yellow kniphofias like ‘Little Maid’ or ‘Wrexham Buttercup,' or even bright fringed tulip varieties.

The bronzed foliage is attractive from early in the season, so plant towards the front with low varieties to avoid hiding the leaves. For fans of dramatic garden color schemes, these are beautiful with low blue nepetas such as ‘Cat’s Pyjamas’ or ‘Purrsian Blue’.

FAQs

Is crocosmia invasive in the US?

In some parts of the US, crocosmia, also known as montbretia, is considered an invasive plant due to its ability to spread. It is considered invasive particularly along the West Coast, but you can also check the National Invasive Species Information Center for more information on planting crocosmia in your local region.

While crocosmia are considered perennials to avoid in a small backyard due to their spreading nature, it's true that some types nowadays are much easier to control. It's best to do research into the growing habit of specific varieties you're interested in before planting in your yard.

Once you have selected the best crocosmia varieties for your outdoor space, consider selecting a couple of other unusual bulbs to plant in spring to grow alongside them for an impactful display.
