For the impatient: fast-growing perennials

The Content Of The Article:

Plant growth is usually slower, especially in the first few years. Luckily, there are some fast starters especially among the perennials, which are used when others take it too slowly. For many people, nature is a recreational space and a haven of peace. Their timeless consistency slows us down and provides regenerative breaks. But sometimes nature is just too slow. Because to wait five years and more, until the hedge has grown tall and the gaps in the perennial flowering close by itself, is not for everyone.

Especially when gardens are remodeled or recreated, there is often a need for fast-growing perennials. These plants give structure to the garden, while slow-growing trees settle and quickly bring green and color to the bed. Even those who have a short-term need for a privacy screen or just an impatient person, for the fast-growing perennials are just the thing. We present a selection of plants that show a lush growth after a short time.


Garden Montbretien Montbretie crocosmia

Garden Montbretien (Crocosmia x crocosmiiflora) or "falling stars" belong to the SchwertliliengewÀchsen. Their growth is similar to that of gladioli. Garden Montbretien grow up to a meter tall and carry up to twenty flowers per branch. The narrow, long, overhanging leaves spread fan-shaped and so the perennial covers a large area in the bed. Due to the high flower stems and their sloped, overhanging habit, Montbretien are well suited for the background in the sunny perennial flowerbed.


Within the Great Cranesbill family, the Armenian Cranesbill (Geranium psilostemon) is the most vigorous. Armenian Cranesbill grows upright up to a meter high. With its large, five-lobed leaves, it covers large areas in sunny or partially shaded backgrounds. Its purple flower makes an impression in June and July.


An equally impressive blooming plant for the bed background or as a low privacy, for example at the fence, is the lupine (Lupinus polyphyllus). The up to 120 centimeters high stems carry up to 50 centimeters large flower candles in all imaginable colors. The flowers open one after another and so the lupine blooms from May to August almost throughout. In an open, sunny location, lupins should always be planted in threes or fives for a quick greening in the garden.

The True Bear Claw (Acanthus mollis) is also listed under the name Weicher BĂ€renklau. He does not come from the BĂ€renklau family (Heracleum), but from the genus Akanthus. True Bear Claw is particularly noticeable by its upright, up to a meter high stem ax, where he wears elegant white flowers. Since the plant is only partially hardy, it needs winter protection in our latitudes.


If you are looking for fast-growing low flowering plants, then you have come to the clove root (Geum). The horstig growing flowering perennials are about 40 inches high and blooming depending on the species and variety between April and August in bright yellow, white, pink or red. In autumn, the small flowering plant flirts with its filigree seeds. Its beautiful foliage also qualifies the clove root as a leaf ornamental plant (for example, Geum coccineum 'Eos'). As a foreground planting in the perennial border or as border planting, the small summer flowering plants are the best in groups.

Red-leaved spurge

Also fast growing is the wintergreen red-leaved spurge (Euphorbia amygdaloides 'Purpurea'). With a height of 50 centimeters, it remains rather low. Its yellow-green flowers sit on brown-red colored leaves, which remain on the plant even in winter, and thus provide an enchanting play of colors. The milkweed is suitable for woody and forest roads as well as for the rock garden.

lily of the valley

The delicate flowers of the lily-of-the-valley (Convallaria majalis) make it hard to guess that this plant has an enormous urge to spread. Especially under trees in the clear shade lilies of the valley spread in no time over large areas and quickly become a complete groundcover. But beware: lilies of the valley are very poisonous and once they have spread they are hard to get rid of!
