- Aromatic foliage, attractive to pollinators.
- Compact, mounding growth habit.

Cultivar Origins and Characteristics
While the exact lineage can be complex within *Nepeta x faassenii* hybrids, 'Purrsian Blue' is specifically bred for its vibrant, rich blue-purple flower spikes that appear from late spring through to autumn. Unlike some older varieties, it tends to rebloom prolifically when deadheaded, offering a continuous display. The plant's leaves are a soft, grey-green and release a distinctive, pleasant scent when brushed or crushed, a trait characteristic of the catmint family that many find appealing.
The plant typically reaches a height of around 30-40 cm (12-16 inches) with a spread of 40-50 cm (16-20 inches), forming a neat, bushy mound. This size and form are ideal for edging beds, filling gaps in perennial borders, or growing in pots and hanging baskets where its trailing habit can be appreciated. Its upright flower stems provide a delicate, airy texture against more solid foliage plants.
Why Choose Nepeta Purrsian Blue Catmint?
Why should Nepeta Purrsian Blue catmint be a consideration for your garden? Its appeal lies in a combination of aesthetic beauty, ecological benefit, and practical garden performance. It offers a continuous display of colour, attracts beneficial insects, and thrives in conditions where many other plants struggle, making it a smart addition for both novice and experienced gardeners.
Attracting Wildlife and Enhancing Biodiversity
The vibrant blue-purple flowers of 'Purrsian Blue' are a magnet for bees, butterflies, and other pollinators. By planting this catmint, you actively contribute to supporting local wildlife populations and enhancing the biodiversity in your garden. Its nectar-rich blooms provide a valuable food source during its extended flowering period, making it an excellent companion plant for vegetable patches or flowering borders alike. The aromatic foliage also helps to deter some common garden pests, offering a natural form of pest control.
The capacity of Nepeta Purrsian Blue to bloom for an extended period makes it a cornerstone for sustained garden colour and pollinator support.
Beyond pollinators, the plant's drought tolerance and adaptability mean it can thrive in less-than-ideal conditions. This resilience translates to less watering and less work for the gardener, freeing up time to enjoy the garden's visual and ecological benefits. It’s a plant that gives back, offering beauty, fragrance, and ecological service with minimal demand.
Growing Nepeta Purrsian Blue Catmint: Basics
Successfully growing Nepeta Purrsian Blue catmint is straightforward, provided you meet its fundamental needs for sunlight, soil, and watering. Understanding these basics will ensure a healthy, flourishing plant that provides season-long interest.
Sunlight and Soil Requirements
For optimal flowering and growth, Nepeta Purrsian Blue catmint requires a location that receives at least six hours of direct sunlight per day. While it can tolerate partial shade, flowering may be reduced, and the plant might become more leggy. It is not overly fussy about soil type but thrives best in well-drained conditions. Waterlogged soil can lead to root rot, so avoid planting it in areas where water tends to stand after rain.
Plant Nepeta Purrsian Blue catmint in well-draining soil, ideally incorporating grit or sand if your soil is heavy clay, to prevent waterlogging and root disease.
Planting and Watering
When planting, dig a hole twice the width of the root ball and of a similar depth. Gently loosen the roots if they are pot-bound before placing the plant in the hole, ensuring the top of the root ball is level with the surrounding soil. Water thoroughly after planting. Once established, 'Purrsian Blue' is remarkably drought-tolerant and prefers drier conditions to overly moist ones. Overwatering can be detrimental, so allow the soil to dry out between waterings.
Feeding and Pruning
This catmint variety generally requires minimal feeding. A light application of a balanced, slow-release fertiliser in early spring is usually sufficient. Over-fertilising can lead to lush foliage at the expense of flowers. The most crucial aspect of care is pruning. To encourage continuous blooming and maintain a tidy shape, deadhead spent flower stalks regularly. A more significant pruning, cutting the plant back by about half its height after the first flush of flowers fades (usually mid-summer), can stimulate a second, abundant bloom cycle through to autumn.
Overwintering and Propagation
Nepeta Purrsian Blue catmint is a hardy perennial and typically overwinters well in most UK climates. Cut back the dead foliage in late autumn or early spring before new growth appears. Propagation is straightforward. You can divide established clumps in spring or autumn, or take cuttings from non-flowering shoots in early summer. Both methods are effective for increasing your stock or sharing with fellow gardeners.
Next Steps: Garden Placement and Alternatives
Considering where to place your Nepeta Purrsian Blue catmint and understanding potential alternatives can refine your planting scheme and ensure you achieve the desired garden aesthetic and function.
Ideal Garden Placements
The compact, mounding habit and prolific flowering make 'Purrsian Blue' incredibly versatile. It is superb for the front or middle of a perennial border, where its delicate blue tones can soften harsher colours or complement yellows and oranges beautifully. Its drought tolerance makes it an excellent choice for gravel gardens, rockeries, or sunny banks where water retention is low. It also performs well in containers, window boxes, or hanging baskets, providing cascading colour and fragrance. Consider planting it along pathways where its scent can be released when brushed past.
When planning, think about its companions. It pairs well with plants that offer contrasting textures and colours, such as ornamental grasses, sedum varieties like *Sedum spurium*, or plants with bold foliage like hostas. For a cottage garden feel, combine it with roses or paeonia lactiflora peonies. Its ability to naturalise slightly also makes it suitable for informal or wilder garden styles.
To maximise its impact, plant Nepeta Purrsian Blue catmint in drifts or groups of three or more, rather than as a single specimen, for a more visually striking display of colour.
Exploring Alternative Catmint Varieties and Similar Plants
While 'Purrsian Blue' is a standout, other catmint cultivars offer variations in size, colour, and habit. For a more vigorous, taller plant, consider 'Six Hills Giant' or 'Walker's Low', which produce larger flower spikes but can grow more expansively. If you prefer a neater, groundcover habit, 'Little Trudy' or 'Cat's Pajamas' might be more suitable options. These offer similar pollinator benefits and fragrance but with distinct growth patterns.
Beyond nepeta itself, other plants offer similar benefits. For similar blue hues and pollinator attraction, look at flowering penstemons, such as 'Garnet', or certain salvias. For drought-tolerant, long-flowering perennials, consider Veronica or Echinacea. If your primary goal is ground cover with attractive foliage and flowers, sedum ground cover plants or certain low-growing thymes could also be good choices, though they will offer different colours and scents.
Ultimately, Nepeta Purrsian Blue catmint is a dependable and rewarding plant. Its ease of care, attractive appearance, and ecological benefits make it a highly recommended addition to most gardens. By understanding its needs and exploring its placement and potential companions, you can ensure it becomes a beloved feature for years to come.
