Rudbeckia Goldsturm, Loukykvět

Rudbeckia fulgida

Rudbeckia Goldsturm is a reliable and long-lived perennial that will bring the warm tones of late summer and autumn into your garden. It originally comes from the open plains and prairies of North America, so it delights most in sunny locations with common garden soil, whether it is loamy, humus-rich, or clayey. You will receive from us an already grown seedling in a pot, which you just need to transplant to the chosen spot in the flower bed. It is a completely undemanding plant, does not suffer from diseases or pests, and easily survives severe frosts. The Goldsturm cultivar grows to a height of about seventy centimeters and does not need support. From August to October, it produces a flood of golden-yellow flowers with distinctly dark centers. These edible flowers attract pollinators and fit perfectly into both prairie and rustic plantings. Rudbeckia is also great for cutting, lasting around ten days in a vase. In addition, the distinctive dark centers can be easily dried. If you leave them in the flower bed over the winter, they will provide a wonderful spectacle.

Brunnera macrophylla, Loukykvět

Brunnera macrophylla

The largeleaf brunnera comes from the moist mountain forests of the Caucasus, where it forms dense undergrowth. It is an ideal perennial for shady and semi-shady corners of your garden, where it will thrive in humus-rich, moist soil. It resembles classic forget-me-nots in appearance, but don't be fooled, its leaves are much larger, heart-shaped, and rough to the touch. Thanks to them, it acts as a great groundcover plant that sprouts early in the spring and reliably covers bare soil with its leaves until late autumn. It thus forms a natural contrasting background for the delicate, tiny flowers. Tiny sky-blue flowers appear in April, May, and June, creating a beautiful delicate veil over the green carpet of leaves. The flower clusters are also suitable for cutting into spring hand-tied bouquets, where they look very tender. Just watch out for snails and slugs, who like to feast on the juicy leaves of the brunnera, so it's a good idea to check the plants regularly. It is a long-lived and hardy perennial that handles severe frosts without problems and will bring you joy in one place for many years.

Loosestrife Swirl, Loukykvět

Lythrum virgatum

Siberian Bugloss, Loukykvět

Brunnera sibirica

Siberian bugloss is a hardy perennial that is unfazed even by the shady corners of the garden where other plants fail to thrive. It earned its name thanks to its tiny blue flowers, which are very similar to classic forget-me-nots and bloom in April and May. Unlike its more famous relative, the largeleaf bugloss, this species spreads a bit more vigorously and forms dense stands.

Once the plant finishes blooming, all its energy moves into the large, deep green heart-shaped leaves, which quickly grow to their final size. It is an ideal choice for beginners because it handles heavier clay soils excellently and tolerates short-term drought. Furthermore, the flowers are suitable for cutting into spring tied bouquets, where they look very tender and add lightness to the arrangement.
