How to let nature fill your yard for free
Self-seeding plants are the quiet heroes of most cottage-style and naturalistic yards. Gently weaving through borders, enriching them with tactile foliage, height and blooms these perennials, grasses and bulbs create swathes of interest that continually shift through seasons, year-on-year.
By knowing which plants happily self-seed in your yard, you can enjoy a beautiful garden that needs little effort, other than occasionally pulling out over-keen seedlings that appear in inconvenient spots.
Columbine
One of the most charming flowers of the cottage garden has to be the spring flowering Aquilegia vulgaris. Also known as columbine, this beauty, with it's bell-like blooms, effortlessly fills gaps in borders and pathways thanks to its generous self-seeding habit.
'Columbine forms delicate, nodding flowers above soft mounds of lacy foliage from April to June,' says plant expert Elin Harryson. 'The blooms change color and shape due to cross-pollination, producing unique, often unpredictable hybrid flowers.
'Its ability to self-seed into small openings, woodland edges, and between other perennials helps gardens feel fuller and more established without appearing overly crowded.'
Thriving in damp areas of dappled shade in USDA Hardiness zones 3-9, this fairy garden plant is happy in most soil types.

Pink Muhly Grass
Pink Muhly Grass is densely tufted, fast-growing grass, producing a mass of slender green blades throughout summer that are topped with frothy pink panicles in fall, that last through winter. One of the best ornamental grasses for winter interest, this laid back beauty mingles gracefully with other grasses and other full sun ground cover plants.
‘Muhlenbergia capillaris is an excellent choice for a self-seeding grass,’ says Plant Expert Nikki Bruner. ‘It brings cloud-like pink plumes in the fall and gently re-seeds without being aggressive. Muhly Grass is low maintenance and drought tolerant, making it perfect for filling space and adding texture.’
Reaching heights of 3ft 3in (1m) with a spread of 1ft 8in (50cm), this sun-loving grass will thread its way through a planted border via its tendency to self-seed and its network of underground rhizomes.

‘Chasmanthium latifolium is a wonderful ornamental grass for seaside gardens and semi-shade gardens,’ says landscape architect, Stacilyn Feldman. ‘It will spread quickly and produces lovely drooping, poetic seed heads that whisper in the wind.’

Golden Alexander
If you are looking for a tall and architectural border-filling perennial that needs next to no effort, consider Zizia aurea, or golden Alexander. Growing up to 3 feet (91cm) high, these vibrant blooms have a touch of the wild-side about them, forming clouds of tiny acid-yellow florets on top of glossy pinnate leaves.
'Golden Alexander produces clusters of bright golden-yellow flowers above deep green foliage from April to June, bringing a meadow-like feel to the garden early in the season,' explains Elin.
'Its ability to self-seed naturally into open spaces and along garden edges helps soften planting transitions and create a fuller, more established landscape over time. Ideal for Zones 3 - 8 in full sun to part shade with average to moist, well-drained soil.'
These meadow flowers are an essential choice for wildflower garden ideas and the latest mosaic planting trend.

Blue Fescue
Clump forming, undemanding and a year-round dazzler there's everything to love about ornamental grass Festuca glauca. With it's fine silver-blue foliage and gentle self-seeding habit, this sun loving perennial provides a beautiful fast-growing contrast to other cottage, prairie and coastal style plantings.
Suited to growing in USDA Hardiness zones 4-8, this grass will flower most prolifically in sandy and loamy soil in direct sun. If flowers are allowed to fully ripen, seedlings will form around the parent plant.
Keep the grassy clumps in good shape with the occasional comb through to remove dead foliage. Plants can also benefit from lifting and division every two or three years. The serrated edge of a Hori Hori Garden Knife, such as this from Lowe's, makes this a simple task.
