Often a perfect lawn can be a “statement” to your home especially when you have scrupulously looked after its condition. You have fed it with all the necessary nutrients, scraped off the moss every year, de-weeded annually and re-seeded accordingly. Often the aspect, the soil, the drainage will all be dependent on its success. However, not many landscapes have these attributes (albeit amenity lawns, sports facilities) and so grass that is not level and imperfect can be made more attractive with the naturalisation of Bulbs and Wild Flowers. Parks especially adopt this due to costs and logistical reasons. Drifts of Bluebells, Daffodils, Crocuses are often used for this purpose. An alternative to picking up an area of grass is to incorporate Wild Flowers. Seed packets of a mixture can be sought or alternatively you may decide to plant your own using colours or tones of your liking..
Some may treat self seeded varieties as weeds (some are welcomed and some not) those that have blown from adjoining fields are often considered a pain but the plethora of colour that can be achieved. It is worth noting that despite hosting in your garden and not asking beforehand there is now colour where otherwise there would have been none.
