Symphytum grandiflorum
Kostival velkokvětý
Symphytum grandiflorum vnese světlo i do těch nejtmavších koutů vaší zahrady. Tato vytrvalá bylina se vyznačuje krémovými, trubkovitými květy, které se objevují už během dubna a jemně kontrastují s tmavě zelenými, chlupatými listy. Je to ideální volba pro výsadbu pod vzrostlé stromy, kde se mnoha jiným rostlinám nedaří kvůli nedostatku světla a konkurenci kořenů. Kostival zde vytvoří souvislý, vitální podrost dorůstající výšky 20 až 40 centimetrů. Kromě estetické funkce plní i důležitou ekologickou roli, protože jeho časné květy poskytují cennou potravu pro probouzející se opylovače. Rostlina je plně mrazuvzdorná a nevyžaduje žádnou speciální péči ani oporu. Mějte však na paměti, že se jedná o druh, který je jedovatý a není určen ke konzumaci, na záhonu však udělá velkou parádu.

Cultivation
Pro úspěšné pěstování kostivalu velkokvětého vyberte stanoviště v polostínu až stínu, kde bude tato vytrvalá bylina prosperovat a každé jaro vás potěší záplavou krémových květů. Sazenice vysazujte do dobře připravené, kypré půdy obohacené o kompost, který zajistí potřebné živiny a pomůže udržet vláhu. Ačkoliv rostlina preferuje hlinitou a humózní půdu, je velmi přizpůsobivá. Při výsadbě dbejte na to, aby byl kořenový bal zcela zakryt zeminou, a po zasazení rostlinu důkladně zalijte. Díky své robustnosti a schopnosti rozrůstat se, je kostival skvělou volbou pro místa, kde se jiným trvalkám nedaří.
Během vegetační sezóny vyžaduje tato trvalka jen minimální údržbu. Zálivka by měla být přiměřená (střední nároky na vláhu 💧💧); půda by neměla zcela vyschnout, ale rostlina nesnáší ani trvalé stání ve vodě. Výhodou kostivalu je jeho fantastická odolnost – netrpí chorobami a škůdci se mu vyhýbají, takže nemusíte používat žádnou chemii. Jedná se o plně mrazuvzdornou rostlinu (zóna 4b), která bez problémů přečká i tuhé zimy bez jakékoliv přikrývky či ochrany. Není třeba ji na zimu stříhat, suché části rostliny se přirozeně rozloží nebo je můžete brzy na jaře vyhrabat pro čistší vzhled záhonu.
Často se ptáte, zda lze tuto rostlinu pěstovat v květináči. Odpověď je ano, kostival v nádobě poroste, ale je třeba mu zajistit stinné místo a pravidelnější přísun vody. V omezeném prostoru květináče se živiny vyčerpají rychleji, proto nezapomeňte na jaře přihnojit univerzálním hnojivem pro trvalky. Ať už na záhoně nebo v nádobě, vždy pamatujte na to, že se jedná o okrasnou rostlinu, která je jedovatá. Není určena ke konzumaci ani k léčebným účelům v domácím prostředí, její krása a užitečnost spočívá v pokrytí půdy a podpoře opylovačů.

Gaura lindheimeri
Gaura Siskiyou Pink
Gaura is a clump-forming perennial native to Texas and Louisiana. Here, it behaves more like a short-lived perennial. It combines beautifully with grasses and adds lightness and airiness to flower beds. It is an excellent food source for insects. Tiny flowers resembling small butterflies bloom tirelessly from June until the first frosts. For bouquets, harvest as soon as the first two or three flowers open on the stem. Siskiyou Pink is a beautiful variety with pink-red flowers on slightly arching stems. It is less hardy than the white-flowering varieties. The red-spotted leaves are also interesting.

Eryngium planum
Sea Holly
A perennial that finds its place in naturalistic steppe and gravel beds. It attracts bees, bumblebees, and butterflies. It is floristically valuable for its flowers with striking bracts, which are also perfect for drying. The roots of some species were formerly eaten candied as sweets in England and France and added to pastries and jellies. In herbal medicine, it was used as an aphrodisiac, among other things, hence its folk name "male fidelity".

Echinacea purpurea
Coneflower Rubinstern
A valuable garden and medicinal perennial, originally from North America. It blooms in summer with dark purple-pink flowers. The spiky flower discs are an irresistible lure for butterflies. Lasts 7–10 days in a vase. After plucking the petals, the stems with the central discs can be dried or used in fresh bouquets as an interesting element. Rubinstern is very similar to the Magnus cultivar; the petals are darker and firmer. As they fade, they gradually pale and droop downwards.

Salvia nemorosa
Woodland Sage Caradonna
This species of sage originally comes from the steppe regions of Central and Eastern Europe. It forms profusely flowering small clumps with straight upright stems. In flower beds, it looks best in groups. Traditionally, due to the identical flowering time, it is planted as a companion to roses. However, it will look just as good in mixed drought-loving steppe plantings with grasses. It lasts 7 days in a vase. The cultivar Caradonna stands out with a long flowering period and dark, almost black-purple stems with tiny purple flowers and dark purple bracts. If we cut it back after flowering, it will bloom again in late August and September.

Helleborus orientalis
Hellebore Double Ellen White
Hellebores are evergreen perennials that form slowly spreading clumps of leathery, dark green leaves. The stems usually bear four to five flowers.

The petals are slightly wavy and the bottom row of petals is lightly tinged with green.
