Flower beds from perennials on the roof - features of the organization
The art of breaking gardens on roofs has long been transformed from the category of a beautiful quirk into a full-fledged fashionable and eco-friendly trend. Small oases of comfort and tranquility, corners for communication with nature and relaxation from the bustle of the city transform the lives of many people. Luxurious potted gardens remain the most popular option. Bright summers and seasonal stars, combined for the greatest effect, are unrivaled. But on the roof you can grow more permanent plants - herbaceous perennials and even shrubs that will delight all year round.

Features of the organization of roof gardening
Roof landscaping allows you to take a fresh look at the recreation areas of offices, high-rise buildings and private houses. But to be limited only to the “urban jungle” is not at all necessary. Any roof can be considered as additional space in order to build a new garden. The desire to create a small oasis also arises when a flat and dull roof opens up from your favorite room or balcony.
Benefits of a Roof Garden
An additional kindergarten on the roof of a house or a garage, outbuildings not only helps to get an additional relaxation area with a magnificent view, but also has a lot of practical advantages. Indeed, thanks to the roof gardens, they optimize the atmosphere inside the house, heat dissipation (in particular, protect them from overheating in the summer), increase air humidity, trap dust, improve the microclimate, contribute to the optimal use of rainwater, escape from noise, etc.
Limitations for Roof Flower Gardens
Roof landscaping options are limited by only two factors:
- The strength of the flooring itself, the ability of the structure to withstand heavy weight (taking into account not only plants and soil, but also snow, structures, containers, decorative elements).
- The quality of the coating, including the presence of damage and a slope of more than 20 degrees, requiring special measures.
To determine the possibilities of breaking an additional roof garden, it is enough to turn to professionals who evaluate the statics of structures.
Roof landscaping options
If the roof parameters allow you to set up a garden, you can select different landscaping options. There are only three of them:
- Temporary or mobile pot garden.
- Stationary planting in the form of flower beds or beds.
- Combined options combining potted and flower frames and flower beds.
Perennials can be used in all three roof gardening options. The simplest of them is planting plants in decorative containers. Unlike summers, perennials will please for many years, requiring only additional protection and shelter for the winter (or bringing them into the room). They are permanent, decorative, create thick curtains. But still, all the beauty of perennial plants is revealed, first of all, due to plantings of a more permanent nature.
Perennials for the roof
For greening roofs use special plants from the category of herbaceous perennials - decorative, with a compact rhizome, creating dense sods that do not require special care, hardy and growing. The bet in the process of creating a roof garden should not be made on the number of plants, but on their ability to create joint full-fledged plantings over time.
The right choice of perennials allows you to minimize maintenance of the roof garden to a minimum of procedures. In fact, if you abandon seasonal plants and summers, as well as potted and potted plants in favor of stationary planting, you will have to pay attention to such a garden only 1-2 times a year.
The easiest way to green the roof is to select pre-made coatings with ground coverings. Indeed, in the form of turf cut into squares, they sell not only lawns, but also more complex compositions with stonecrops, young plants, and other unpretentious plants. You can study the range of ready-to-plant types of decorative coatings at local garden centers.
If perennials are used for a pot garden, then the choice is almost unlimited. For planting in containers and flower containers, decorative-deciduous crops and aromatic spicy herbs are most often chosen. Lavender, mint, lemon balm, oatmeal, crest, wormwood, St. John's wort, thyme, cuffs, heichera, sheep - these are just a few plants that can replace summers in containers. Perennial soil protectors and vines from periwinkles to ivy do an excellent job with the function of the landscaper.
Choosing Plants for Permanent Compositions
When creating permanent compositions of flower beds on the roof, several other cultures come to the fore:
- Absolute favorites of landscaping roofs are succulents. Thawing, stonecrops, saxifrages, thyme and Co. are content with a minimal layer of fertile soil and withstand any heat and drought.
- Of the more powerful perennials, narrow-leaved lavender, variegated and dwarf irises, bearberry, quadrangular evening primrose, Carpathian bells are used in the design of compositions on the roof. Kittens, aquilegia, window sill, stonecrops and ground-covering phloxes show excellent performance in roof gardens.
- Of the cereals, it is worth paying attention to the evergreen sheep, fan flower, combed spartine, oatmeal, Chinese miscanthus and soddy meadow. If you sow the seeds of the hare tail and other annual cereals once, they will spread by self-sowing and introduce the effect of improvisation into the composition. Like flowering flyers - such as kosmey blood red.
There is a place on the roof for larger plants. Of the bushes for landscaping the roofs, the most unpretentious hardy and compact species are used. Meyer lilacs of the smallest varieties, steppe almonds, feminine rosehips, evergreen stars in the form of weymouth and small-flowered spruce, ordinary dwarf varieties are excellent candidates for the role of single accents and introducing volume and structure into the composition.
For touching accents and seasonal spots in the roof gardens, you can freely use onion bulbs. Such a small garden can become a full-fledged laboratory for exploring exotics or new varieties. Bulb lovers can create a whole torch of flowering, and compositions in which it is onion flowers that will become real stars. From the first touching snowdrops to crocuses, mouse hyacinth, species and varietal tulips with hyacinths to daffodils - there are plenty to choose candidates for the spring show. Their flowering will also be picked up by decorative bows - Qatar, round-headed, and lilies.
Practical nuances of growing perennials on the roof
To grow perennials on the roof in specially created flower beds, discounts, beds or spots, you need to take care not only about the choice of plants.
Firstly, the borders of the flower garden and planting zones must be strictly limited: plants are planted only in compositions created on the basis of raised beds or beds - towering above the general level of the roof.
The layout of the roof garden needs to be carefully thought out, leaving enough space for a comfortable stay, movement, and plant care. Decorative paving, the creation of coatings, the arrangement of recreation areas, especially if shading structures are planned, are completed before proceeding with the actual landscaping.
To break down flower beds with perennials on the roof, it will be necessary to additionally line it with a protective root insulation coating in the area within which the object will be created. The protective coating is additionally covered with non-woven materials, and only then they begin to fill the structures themselves. The wooden border, plastic structures, fashionable portable modules are selected depending on the desired style and design concept.
Finished “frames” are filled with several layers of substrate. The lower layer of flower beds is created from drainage, which is mandatory for any stationary objects on the roof (with a layer of at least 10 cm). The drainage is covered with filter fiber, and only then a layer of nutritious, high-quality, loose soil is poured into which the plants will be planted.
The layer of substrate or fertile soil on the flower beds on the roof directly determines not only the total weight of the entire structure and kindergarten, but also which plants can be used. For succulents, 5-7 cm of soil is enough, but other herbaceous plants will need a larger space and a layer of substrate with a thickness of 8 to 12 cm.
Oddly enough, the thickest layer of soil should be for lawns - about 15-20 cm. But such a layer of soil will allow to plant cereals, and large, forming powerful roots of perennials, and even decorative medium-sized shrubs.
To create a roof garden, strong seedlings with a closed root system are used. Small delenki or plants with bare roots will adapt for a long time and may die in specific climatic conditions. When choosing planting material, it is important to pay attention to well-developed roots, the absence of traces of pests and diseases, and active growth.
