Onyx Odyssey Helleborus is a herbaceous evergreen perennial that grows in an upright spreading style. Although its medium texture fits into the environment, it can be complemented with a few finer or coarser plants for an amazing composition. It has very huge, totally double, cup-shaped flowers that are 3 inches diameter (7 cm), packed with 15-20 petals in colours ranging from slate to deep purple to black. Over time, the blossoms do not lose much of their vibrant hue. These nodding beauties, which bloom profusely for weeks in late winter to early spring, rise on sturdy, thick stems atop the leathery, glossy, evergreen foliage, which emerges purple before turning an appealing shade of green. ‘Onyx Odyssey’, a showy and enduring double helleborus from the Winter Jewel series, pairs beautifully with helleborus ‘Golden Lotus’ to produce excellent flower arrangements.
Planting Onyx Odyssey Helleborus
- Choose a location with full to partial shade and rich, wet organic soil. Choose a place where plants will be less vulnerable to winter harm.
- Dig the ground to a depth of six to twelve inches, clear the area of any trash, and then gently rake the ground to level it out.
- Organic matter (leaf mould, compost, well-rotted manure) enriches all gardens and is especially important in newly built neighbourhoods.
- To reduce transplant shock, plant on a cloudy day or in the late afternoon.
- Make a hole large enough to accommodate the root ball for each plant.
- To encourage excellent root growth, unpot the plant and carefully loosen the root ball using your hands.
- Make the top of the root ball level with the surrounding soil. Fill the root ball with dirt all the way to the top. Firmly press the dirt down with your palm.
- Use the plant tag to mark your location.
- To conserve water and reduce weeds, water thoroughly and apply a light mulch layer (1-2 inch) on top of the soil.
Onyx Odyssey Helleborus Care
The Onyx Odyssey Helleborus plant is a low-maintenance plant. Despite the fact that it must be worked hard to meet its fundamental light, water, temperature, and soil requirements. Perennials need to be watered carefully to get them started. To encourage young roots to swell deeply, water thoroughly at least once each week. One inch or so below the soil’s surface, the soil should be wet. You can confirm this by putting your finger in the ground. Water in the early hours of the morning to allow all of the leaves to dry. The majority of perennial plants need an inch of rain or weekly irrigation. Using a rain gauge, you can determine whether you need to add water.
Additionally essential is good airflow. A mild fertiliser can be administered after new growth starts to show. To prevent burn damage, keep granular fertilisers away from the plant’s top and foliage. Use Garden-tone or another slow-release fertiliser at low rates; greater rates could promote root rots. Once the foliage has bloomed, trim it back. Don’t mulch in the autumn to preserve plants from the winter. This might choke that plant. Helleborus frequently self-sow and rarely need to be divided. Prevent from uprooting plants once they have grown.
