By planting larger plants, you can achieve two effects: create the dominant zone of our flowerbed or arrange its background in an interesting way. Contrary to classic ornamental perennials, such as delphiniums or lilies, these sizable perennials are relatively easy to care for and reach a height of 1.5 to 2.5 meters. The giant plants often captivate not only with their large, candle-shaped inflorescences in the shape of candles or loose umbels and panicles, but also with attractive leaves. In addition, tall perennials enchant us with their natural beauty. Their size goes hand in hand with a long period of growth - they reach full bloom in summer or even in autumn.Some large perennials decorate the garden even in winter: Angelica's shoots are long decorated with round inflorescences, and meadowsweet Filipendula 'Venusta' retains red inflorescence panicles. Trim these specimens only in early spring.
Giant perennials for shady places
Aruncus forest perennial and Ligularia tongue grow in shady and moist spots, preferably at the edge of a pond . In sunny flowerbeds, the Macleya bokonia (oblans), up to 2.5 meters high, willowleaf sunflower Helianthus salicifolius with narrow leaves, and Crambe cordifolia, whose white veins of inflorescences flutter at a height of 1.8 meters, bloom. The areas around the ponds and wet positions are well tolerated by the Gunner parzeplins with huge spiky leaves growing up to 3 meters. For the winter, the rhizomes of this perennial should be covered with a thick layer of leaves.
The difference in height of adjacent perennials should not be too large if we want the composition to be harmonious.In addition to the height of the selected species, their requirements should also be taken into account, especially when we have a small discount area. Selected perennials can be interesting elements in the background of the backyard garden or serve as a protective hedge on the border of the garden.
Conditions for growing large perennialsTall perennials grow best on normal ground garden with balanced proportions of nutrients. The soil should be regularly hydrated, as its insufficient moisture will cause the larger leaves to wilt. A five-centimeter layer of bark will protect the substrate from excessive water evaporation and reduce frequent watering. In the case of bokonia, in the first and second years, strongly growing stolons and thick roots occupy an area of several square meters. Other species are less expansive, but have enormous leaves, such as gunnera or modrak. Such giants look best in large gardens, where you can freely display their beauty without risking the development of other smaller plants.
