Perennial and Grass Collection with Bulbs and Seeds

Blue tones in the garden bed

Our perennial selection in blue. We have supplemented it with our favorite blue annual seeds and added blue-flowering spring bulbs. Ornamental grasses are also a must. Everything is ready to conjure up a blue mood in your garden. Just choose a sunny spot with good soil and access to water. When planning, calculate an average of six to seven perennial plants per m²; it always depends on the quality of the soil in your garden and your intentions. In nutritious and sufficiently moist soil, perennials will grow faster and initial spacing can be larger, while in poorer conditions, it is better to plant more densely. The time you can dedicate to garden maintenance will also be a deciding factor. Our collection is flexible, allowing you to creatively adapt it to your needs and garden. In the cart, you can easily adjust the number of plants or swap in suitable species and cultivars. For example, if you already grow some of the perennials in this collection and only need to fill in your flowerbed, you can simply keep your preferred perennials in the cart. During an autumn purchase, you can take advantage of available bulbs and order the complete collection, including spring bulbs and alliums, which will ensure your flowerbed has plenty of blooms in both spring and summer. Show full description

Salvia Blauhügel, Loukykvět

Salvia nemorosa

This species of Salvia originally comes from the steppe regions of Central and Eastern Europe. It forms richly flowering small clumps with straight upright stems. In beds, it looks best in groups. Traditionally, it is planted as a companion to roses due to the same flowering time. However, it will look equally good in mixed drought-loving steppe plantings with grasses. It lasts 7 days in a vase. 'Blauhügel' blooms blue.

Spanish Bluebell Blue, Loukykvět
Fragrant

Hyacinthoides hispanica

The Spanish Bluebell is a beautiful bulbous plant native to southwestern Europe, where it grows in light deciduous forests. Multiple leaves grow from the bulb, but only one flower stalk. The plant propagates well on its own in the right location via daughter bulbs and seeds, creating colonies. It blooms from May to June. The leaves die back soon after flowering. For the longest vase life, it is best to harvest them just before the florets open. Then they last up to 14 days in a vase.

Milky bellflower Prichard's Var., Loukykvět

Campanula lactiflora

Milky bellflower will bring the atmosphere of wild mountain meadows into your garden. Its original home is the regions of the Caucasus and western Asia, where it grows on the edges of sparse forests and in shrubberies. You will receive a grown seedling in a pot from us, which you simply need to transplant straight into a sunny spot with loamy soil. This bellflower is very undemanding and even beginners can easily handle its care, as it reliably withstands frosts down to minus twenty-eight degrees and is avoided by diseases and pests. In the flowerbed, it will form roughly ninety-centimeter-tall clumps with green leaves, for which it is a good idea to consider light support. It thrives excellently in the company of plants that will not compete with it too much with a vigorous root system. It therefore looks absolutely perfect as a companion for roses or hydrangeas. The Prichard's Var. cultivar stands out from June to August with a flood of blue to purple-blue flowers, whose color is much richer than that of the basic species. The long stems of this bellflower are practically destined for cutting into summer bouquets. In a vase, the fresh flowers will last to bring you joy for an amazing fourteen days.

Switchgrass Prairie Sky, Loukykvět

Panicum virgatum

A perennial grass native to North American prairies. Switchgrass is very adaptable and long-lived. It adds clear structure to flower beds and simultaneously functions as a softening element. This is especially true after veil-like flowers appear above the clumps of leaves. Prairie Sky is probably the bluest cultivar of perennial switchgrass. It is not as strictly built as Heavy Metal. Its clumps are looser, and it turns yellow in autumn.

Didiscus Lacy Blue, Loukykvět

Didiscus caerulea

Didiscus has a strange name, but it is a great beauty similar to Ammi or ornamental carrot. The flowers are disc-shaped with tiny florets. Didiscus finishes blooming faster, similar to Ammi or ornamental carrot, so we recommend succession sowing. It likes warmth, so it can be sown even in summer.

Sea Holly, Loukykvět
For drying

Eryngium planum

Sea holly is an indispensable perennial for all lovers of naturally styled gardens. It earned its folk name - male fidelity - in times when it was used in herbal medicine as an aphrodisiac, and its roots were even candied as sweets in France and England. Today, however, you will appreciate it mainly for its low maintenance and unique appearance. Its home is on sunny hillsides and dry meadows, so even in our gardens, it will welcome well-drained, even poorer sandy soil and full sun. It produces upright, sturdy stems topped with blue-purple flowers with prickly bracts, which bring interesting structure and a silvery touch to the flowerbeds. It is literally a magnetic plant for bees, bumblebees, and butterflies, who find a rich food source on it. Floristically, it is extremely valuable, because its flowers are perfectly suited for cutting as well as drying for winter decorations. If you decide not to harvest it, feel free to leave it in the flowerbed all winter. Its silhouette covered in hoarfrost creates a wonderful winter effect. Although it is a short-lived perennial, in a suitable location it reliably self-seeds, so you will enjoy its beauty for many years.

Larkspur QIS Light Blue, Loukykvět

Delphinium consolida

Larkspurs are spring beauties that nothing compares to. However, if you want to harvest them for cut flowers, you must be vigilant and harvest quickly before all the buds open. They finish blooming quickly, especially during the warm springs of recent years, so we sow several batches 14 days apart just to keep up with the harvest. Larkspur QIS White is a soft white that fits beautifully into wedding floristry. You harvest one stronger stem and 4-5 smaller side stems from a single plant.

Hyssop Caeruleus, Loukykvět

Hyssopus officinalis

A Mediterranean herb and ornamental subshrub in one, that is the hyssop variety 'Caeruleus'. It originally comes from the warm regions of southern Europe, where it colonizes sun-drenched rocky slopes. Thanks to this, it is exceptionally drought-resistant and thrives in direct sun in well-drained, sandy soil poor in nutrients. Although it loves heat, it is fully frost-hardy. In the winter months, it also maintains an interesting shape in the flowerbed, creating a nice winter effect. We will deliver a mature potted seedling that you can easily transplant directly into your garden. It will soon become a richly branched small shrub. Caring for it is undemanding, and it does not suffer from pests or diseases. From summer to autumn, the 'Caeruleus' variety will delight you with a flood of tiny flowers in an amazing blue-violet shade. Both the flowers and the green leaves emit a strong spicy fragrance that reliably attracts bees and butterflies. Hyssop is an excellent edible herb with culinary uses. In ornamental beds, it works as a perfect alternative to lavender. It beautifully complements plantings with roses as well as modern gravel beds. You can also cut the flowers on their sturdy stems for fresh bouquets, where they will bring an interesting vertical element.

Flax Sky Blue, Loukykvět

Linum usitatissimum

For drying, round capsules formed by flax after flowering are used. You need to catch the right time when they are mature and the stem below the capsule is firm. Do not wait too long, however, so you achieve a nice golden color after drying. Just hang them upside down in a dry and ventilated place, out of direct sunlight.

Larkspur Benary’s Pacific Cameliard, Loukykvět

Delphinium hybrida

The larkspur cultivar Benary’s Pacific Cameliard will bring vertical dynamics and bright blue color to your flowerbeds. The original botanical species of larkspurs originate from mountain valleys and moister grassy plains, from which stems their love for nutritious, well-drained, and moderately moist loamy soil. In a sunny location, it will reward you with rapid growth and strong stems that commonly grow to a height of one and a half meters. We will send you home a beautifully rooted seedling in a pot, ready for immediate planting. We recommend maintaining a spacing of sixty centimeters; the plants need freer space around them to ventilate well and not suffer from powdery mildew. Larkspurs belong among perennials that require a bit more attention, and therefore, they are appreciated more by advanced gardeners. During growth and blooming, they need to be watered regularly and occasionally fertilized so that they have the strength to form large inflorescences. In spring, it is necessary to protect the young green leaves from slugs and snails. The plant is fully frost-resistant and will survive winter with temperatures down to minus thirty-four degrees without any protection, but keep in mind that it is entirely poisonous. The blue flowers appear in June and, after a summer break, if you cut the plant back after the first blooming, again at the end of August and in September. During blooming, the larkspur is swarmed by bees and functions as a perfect dominant feature behind shorter perennials. You can use it for cutting into tall summer bouquets. It will stay beautiful in a vase for a whole week, you just must not place it near a bowl of fruit. Ethylene released from apples or bananas causes the flowers to drop. If you like creating dried arrangements, definitely dry the larkspur; its petals will reliably retain their deep blue shade throughout the winter.

Larkspur Morpho Grand Blue, Loukykvět

Delphinium grandiflorum

Larkspur Morpho definitely doesn't look like just any ordinary Larkspur! The flowers are single and positioned on long stalks. It creates a much airier and lighter impression than we are used to with Larkspurs. At the same time, it works beautifully as a filler in bouquets, as the stems are branching with plenty of tiny blooms. Morpho Grand Blue is a shade of deep, vibrant blue, quite rare in flowers.

Catmint Walker’s Low, Loukykvět

Nepeta racemosa

Catmints are ideal companions for roses, suitable for naturalistic gardens, and lower species also for boxes and pots. Some of them are an irresistible attraction for cats, caused by the hallucinogen nepetalactone. This should be present in the highest amount in the species Nepeta cataria. Conversely, lemon-scented catmints reportedly do not attract cats. The botanical name Nepeta likely comes from the name of the ancient Etruscan city Nepet - Nepi in the territory of today's Italian province of Viterbo, where the plant was once cultivated. Nepeta racemosa naturally grows on dry meadows and rocky, stony slopes from the Caucasus to Central Asia. It has aromatic grey-green leaves and forms a tufted semi-spherical bush. Walker’s Low got its name after an Irish estate where it was bred in 1970. It has the most intense blue-violet flower coloration.
