Oxypetalum caerulea

Tweedia Heavenly Blue

We need a full color palette on hand at every moment of the season, and blue is the biggest trouble. We searched for a long time for a blue variety that would bloom even in the warm late summer months. And Tweedia is finally the one! The color is a shade of turquoise rarely seen in flowers. Show full description

Daucus carota

Pure splendor! We don't have nicer photos for this year because every year we cut the ornamental carrot down to the last stem and there is simply no time left for photos. Thin, strong stems and umbel inflorescences resembling dill at their ends. There are thousands of tiny flowers on each stem creating a veil or lace effect. It is a mixture of colors, where some flowers are pure white, but the majority are chocolate to burgundy with a touch of white.

Cynoglossum amabile

Although correctly it is the Chinese hound's tongue, on the farm we don't call it anything other than forget-me-not! Unlike the classic water forget-me-not that we all know, this species has massive and long stems perfectly suited for binding. The color is a very fresh and distinct blue. Each plant produces 6-8 stems, and if you let some fade and ripen, seeds are easily collected.

Cosmos bipinnatus

Cosmos are one of the most popular flowers on our farm. They resemble Daisies and customers love them. And now imagine that such a hit comes in a double-flowered version! Absolutely magnificent! A flood of flowers resembling cotton candy; the Bicolor pink variant is full of soft pink shades. Some blooms are cool pink and others are in a warm blush color. One plant produces at least 12 stems.

Orlaya grandiflora

Orlaya is a floral variety somewhere between Ammi and ornamental carrot. However, it also has outer flowers with large petals, creating the impression of lace or embroidery. The stems are strong and straight, fitting beautifully into bouquets. And after flowering, tiny seed heads form which are also beautifully decorative and do not wilt; we love harvesting those too.

Bupleurum rotundifolium

Our favorite foliage and filler. It grows beautifully and binds famously! The flowers are yellowish, so they don't color-match every bouquet, but we still never have enough of it! And after flowering, tiny seed pods form which are also beautifully decorative and don't wilt; we love collecting those too.

Eryngium planum

An evergreen favorite at the flower market! Sea Holly is a perennial; it lasts for several years in the flowerbed and spreads beautifully. The "flowers" and leaves are slightly prickly; it does look like a miniature thistle after all. The stems and tops are silvery blue. And mature, bloomed Sea Holly doesn't wilt, making it great for drying, wreaths, and similar uses. For drying, harvest when the thistles are colored blue and the stem below the thistle is firm. Just hang them upside down in a dry, ventilated place, out of sunlight.

Delphinium consolida

Larkspurs are spring beauties that are unmatched. But if you want to harvest them for cut flowers, you must be vigilant and harvest quickly before all buds open. Especially in the warm springs of recent years, they bloom quickly, so we sow several batches 14 days apart just to keep up with the harvest. Larkspur QIS White is a delicate white, fitting beautifully into wedding floristry. From one plant you will harvest one thicker stem and 4-5 smaller side ones.

Limonium sinuatum

Statice is a classic from grandma's garden, but also an evergreen of dried flowers. We grow statice by the hundreds! It is incredibly useful in bouquets as filler material and even undried lasts a long time in a vase. Once all the florets on the stem bloom, statice no longer wilts and is suitable for wreaths, corsages, boutonnieres. One plant produces at least 15 stems. For drying, we harvest statice at the stage when the stem under the flower is firm and the entire inflorescence has bloomed. Just hang them upside down, in a dry and ventilated place, out of sunlight.

Panicum elegans

We think mixing different textures is the most beautiful approach for both bouquets and flower beds. And we haven't seen an effect like the one created by this ornamental grass before! After blooming, the top of the stem bursts into a delicate firework display. We use it in wedding corsages all the time; it creates a wonderful impression in bouquets, and in larger quantities in a flower bed, it is pure charm! They are also great for drying! Harvest when the blooms are mature (their light green color is replaced by darker shades of green to brown). Just hang them upside down in a dry, ventilated place out of direct sunlight.

Saponaria vaccaria

An interesting name and an unusual flower resembling baby's breath. The rich blooms on the stems invite you to divide them into several smaller vases to decorate a windowsill. It finishes blooming quickly, so we recommend succession planting. You will harvest 3-4 stems from a single plant.

Matthiola incana

Stock is a wonderful cut flower! It likes low temperatures, yet we grow three batches a year – two in spring and one in autumn. You harvest just one bloom per plant, but it is a really large, double one. Stock smells beautiful, almost intoxicating, and lasts a long time in a vase. The flowers are edible. The Katz series is not as susceptible to temperature changes, and is generally easier to grow for beginning gardeners. However, this comes at the cost of thinner stems and a lower percentage of double flowers. Katz Cherry Blossom is a soft shade of pink in the colors of apple blossoms. All stocks produce some plants with double flowers and some single. The ratio is different for each series. Katz has 55-60% double-flowered plants. We therefore recommend growing a bit more. At our farm, however, we use the single ones too; they look super unique.

Eucalyptus cinerea

Eucalyptus (also known as gum tree) is one of the most requested greens and fillers in floristry ever, it is trendy! The color is silvery blue-green, which is such a combination that we are not surprised by its popularity at all. Eucalyptus Silver "Dollar" grows beautifully tall, the branches are more sparsely built. The leaves are larger and round in shape. The color of Silver Dollar is more silvery and thus in floristry fits rather into colder color combinations. For drying, we harvest as soon as the tips of the twigs are mature and the last leaves are firm. Just hang them upside down, in a dry and ventilated place, out of sunlight.

Cultivation

LETNIČKA nebo TRVALKA

Tvídie je trvalka, ale v našich končinách ji můžeme pěstovat pouze jako letničku. Není totiž mrazuvzdorná a vydrží nejnižší teploty okolo 5°C. Jedinou možností je tedy vytápěný fóliovník nebo pěstování jako letničku.

VÝSEV

Sejeme 7-8 týdnů před posledními mrazy na povrch a zasypeme tenkou vrstvou substrátu. Udržujeme vlhké, dokud semena nevyklíčí. Ke klíčení je potřeba vyšší teplota 22°C. Klíčení semen může být nerovnoměrné a trvat delší dobu, klidně i několik týdnů.

Ven přesazujeme až po posledních mrazech.

Tvídie potřebuje živné, dobře propustné půdy a slunce nebo polostín.

The information given is based on our experience, please use it as a guide only. Times may vary depending on the season, climate, location, sowing and transplanting dates and possibly also the conditions in the greenhouse/greenhouse. We always recommend testing how the plant performs in your conditions. Please do not take this as a guarantee.
