What Are Geum Varieties?
Geum, commonly known as avens, is a genus of flowering plants celebrated for their cheerful, often vibrantly coloured blooms and long flowering seasons. While wild geum species exist, the varieties most sought after by gardeners are cultivars bred for enhanced ornamental qualities. These plants are hardy herbaceous perennials, meaning they return year after year, forming clumps of foliage from which flower stalks emerge. The appeal of geum varieties lies in their adaptability and the sheer range of colours and forms available, from delicate, nodding bells to more robust, upright displays, making them a versatile addition to almost any garden setting.
Their popularity stems from their ability to provide continuous colour, often from late spring until the first frosts. Unlike many plants that have a short, intense bloom period, geums tend to offer a succession of flowers, especially with a little care. This makes them invaluable for maintaining visual interest in borders, rockeries, and even containers. The diverse palette includes shades of orange, red, yellow, pink, and white, with many cultivars featuring double or semi-double petals that add a touch of elegance.

Why Choose Geum Varieties for Your Garden?
The primary draw for incorporating geum varieties into garden designs is their impressive floral longevity coupled with their relative ease of care. For gardeners seeking a reliable source of colour without demanding maintenance, geums present an excellent solution. Many varieties are also quite resilient, tolerating a range of soil conditions provided they are not waterlogged. Their compact to medium growth habit means they fit well into mixed borders, intermingled with other perennials and shrubs, adding texture and vibrant hues without overwhelming surrounding plants.
Furthermore, geums serve as excellent companions for other garden favourites. Their colours can complement or contrast beautifully with plants like salvias, hostas, and even some types of roses. While the question of whether hosta plants flower is common, geums provide guaranteed, showy blooms. Their ability to attract pollinators, such as bees and butterflies, also contributes to a healthy garden ecosystem. This makes them a choice that is both aesthetically pleasing and environmentally beneficial.
Exploring Popular Geum Cultivars
The sheer diversity within the geum genus means there's a variety to suit most tastes and garden situations. While countless cultivars exist, some have gained particular recognition for their exceptional performance and striking appearance. Understanding these popular types can help you identify plants that align with your desired garden aesthetic.
Fiery Oranges and Reds
For those drawn to warm, intense colours, geums like Geum 'Totally Tangerine' and Geum 'Mrs. J. Bradshaw' are outstanding choices. 'Totally Tangerine' is renowned for its profusion of vibrant, semi-double, tangerine-orange flowers held on tall stems, blooming for an extended period. 'Mrs. J. Bradshaw' offers classic, deep scarlet-red, double flowers that create a dramatic focal point. These varieties are robust and provide a strong visual impact, particularly effective when planted in drifts or massed for a carpet of fiery colour. They are excellent for adding a tropical feel or a splash of sunset hues to the garden.
Soft Pinks and Peaches
If a gentler colour palette is preferred, cultivars such as Geum 'Pink Fluffy' or Geum 'Firestorm' (which can exhibit peachy-orange tones) provide a softer, yet still cheerful, presence. 'Pink Fluffy' boasts delicate, ruffled pink petals, offering a more ethereal display. While 'Firestorm' often leans towards vibrant orange, its hues can sometimes take on peachy or apricot tones, especially in different light conditions. These softer shades blend harmoniously with pastel planting schemes and are ideal for creating romantic, cottage-style borders.
Sunny Yellows and Whites
Brightening up shadier corners or adding a cheerful lift, yellow and white geum varieties are invaluable. Geum 'Lemon Drops' provides a delightful cascade of pale yellow, nodding flowers, creating a light and airy effect. For pure white blooms, look for cultivars like Geum 'White Avens', which offer a clean, crisp contrast to darker foliage or more vibrant neighbours. These lighter colours are excellent for illuminating garden paths or for use in mixed containers where they can bring a touch of radiance.
Plant geums in groups of three or five for the most impactful display; their colours and forms truly shine when seen en masse.
Understanding Bloom Times and Habit
While most geums bloom from late spring through summer, their exact flowering times can vary slightly by cultivar and climate. Some, like 'Totally Tangerine', are particularly long-flowering, often continuing well into autumn if deadheaded. Others might have a more concentrated bloom period. Their growth habit ranges from low-spreading mounds of foliage to more upright, taller stems. It's worth noting how long do peonies last; geums offer a much more extended flowering period, making them a more consistent performer throughout the season.
Cultivating Your Geum Varieties
Successfully growing geum varieties involves understanding their basic needs for light, soil, and moisture, along with a few simple care techniques that promote prolific flowering and plant health. While generally unfussy, providing the right conditions ensures your geums thrive and deliver their best performance year after year.
Ideal Growing Conditions
Geums generally prefer a spot in full sun to partial shade. In hotter climates, a location that offers some afternoon shade can prevent their leaves from scorching and prolong flowering. They are adaptable to a range of soil types but perform best in well-drained, moderately fertile soil. Avoid heavy, waterlogged clay, as this can lead to root rot. If your soil is heavy, incorporating organic matter such as compost or well-rotted manure will improve drainage and soil structure. This preparation is key, much like when preparing soil for dividing agapanthus or ensuring good drainage for other moisture-sensitive plants.
Planting and Spacing
When planting geums, whether as bare-root plants, potted specimens, or divisions, ensure they are placed at a depth that matches their original soil level. Space plants according to their mature size, typically between 30-45 cm (12-18 inches) apart, to allow for good air circulation, which helps prevent fungal diseases. For new plantings, watering thoroughly after planting is crucial to help settle the soil and reduce transplant shock.
Watering and Feeding
During their first growing season, geums will benefit from regular watering to establish a strong root system. Once established, they are moderately drought-tolerant but will flower more profusely if given supplemental water during dry spells. Feeding is generally not intensive; a light mulch of compost around the base in spring, or a balanced liquid feed applied once in spring, is usually sufficient. Over-fertilising can lead to lush foliage at the expense of flowers, similar to problems with salvias if they receive too much nitrogen.
Deadheading and Pruning
To encourage continuous blooming, deadheading spent flowers is a vital practice. Simply trim off the flower stalks as soon as the blooms fade. Many geum varieties will then produce a second flush of flowers. For plants that have finished flowering completely or to tidy them up for winter, cut the entire plant back to ground level in late autumn or early spring. This also helps to prevent self-seeding if you wish to control their spread. This rejuvenation process is akin to when to separate agapanthus or the best time to split hostas, ensuring vigour for the following season.
Regular deadheading is the single most effective way to maximise the flowering period of your geum varieties.
Propagation and Division
Geums are generally straightforward to propagate and divide, allowing you to increase your stock or rejuvenate older plants. This process is often best undertaken when plants are actively growing but before they become too large or stressed, ensuring a smooth transition and successful establishment.
Division
The most common method for propagating established geum varieties is by division. This is typically carried out in early spring, just as new growth begins to emerge, or in early autumn after flowering has finished. Over time, geum clumps can become congested, leading to reduced flowering and a less vigorous appearance. Dividing them every 2-3 years helps to maintain their health and vigour.
To divide, carefully dig up the entire plant using a spade or garden fork. Gently tease apart the root ball into smaller sections, ensuring each section has healthy roots and a few growing points. Discard any woody or unhealthy portions. You can replant the divisions immediately into prepared soil, watering them in well. If dividing in spring, they will typically establish and flower in the same year. Autumn division allows roots to establish over winter, ready for spring growth. This timing is crucial, much like the best time to split hostas for optimal results.
Seed Propagation
Some geum varieties can be grown from seed, though it's important to note that cultivars may not come true from seed, meaning they might not look exactly like the parent plant. This method is more suited to species geums or if you are happy to experiment with variations. Sow seeds in trays of seed compost in a cool greenhouse or propagator in spring. Germination can be erratic, and seedlings may take some time to develop. Once large enough to handle, prick out the seedlings into individual pots and grow them on before planting them into their final positions.
When dividing, look for sections with healthy roots and at least one or two new shoots.
Cuttings
Softwood cuttings can also be taken from geum varieties in late spring or early summer. Select healthy, non-flowering shoots, cut them to about 7-10 cm (3-4 inches) long, and remove the lower leaves. Insert the cuttings into pots of well-drained compost or a mix of compost and grit. Keep them in a propagator or cover the pots with a plastic bag to maintain humidity. Once they have rooted (usually after 3-4 weeks), they can be potted on individually and hardened off before planting out.
Choosing the Right Geum for Your Garden
Selecting the ideal geum varieties involves considering your garden's specific conditions, your aesthetic preferences, and the overall planting scheme you aim to achieve. With their diverse characteristics, geums can fill many roles, from vibrant border fillers to delicate accents.
Assessing Your Garden's Conditions
Consider the sunlight levels in your garden. Most geums perform best in full sun, which encourages abundant flowering. However, if you have an area that receives only partial shade, particularly in the hot afternoon sun, some varieties will still perform well, often with slightly less intense colours or a slightly shorter bloom time. Ensure the soil is well-drained; geums do not tolerate waterlogged conditions, so if your garden tends to hold water, consider raised beds or improving soil drainage significantly.
Matching Varieties to Your Style
For a cottage garden feel, opt for softer shades like pinks, peaches, and paler oranges, perhaps alongside plants like foxgloves (though yellow foxglove plants are a specific variety, the general concept applies) or lupins. Do lupins flower the first year? Yes, often they do, and they can complement geums beautifully. If you prefer a bold, contemporary look, intense reds and oranges like 'Totally Tangerine' or 'Mrs. J. Bradshaw' will make a strong statement. For rock gardens or borders with a more delicate touch, consider the lower-growing, single-flowered types with lighter colours.
Complementary Planting Partners
Geums look fantastic when paired with a variety of other garden plants. Their long flowering season means they can bridge gaps between the blooms of spring bulbs and the autumn displays. Consider planting them near plants with contrasting foliage textures, such as ferns or ornamental grasses. They are also excellent companions for plants that might not flower for as long, ensuring continuous colour. For instance, do hosta plants flower? Yes, but their blooms are often secondary to their foliage; geums ensure a strong floral presence. Slug-proof hostas can be placed near geums, as geums are generally less susceptible to slugs and snails than hostas.
Long-Term Appeal
When choosing, think about the plant's overall habit and how it will integrate with neighbouring plants. Some geums have a more upright, architectural presence, while others are more mounding. Their evergreen or semi-evergreen foliage can also provide winter interest, though they benefit from a trim back in early spring. By selecting varieties that suit your specific microclimate and design intentions, you can ensure a rewarding and colourful display from your geum plants for many years to come.
