Stinking Hellebore Helleborus foetidus 'Yellow Wilgenbroek'
ABOUT
The 'Yellow Wilgenbroek' is a variety of the plant commonly known as the stinking hellebore. It is a perennial with a naturally upright habit, and it is most noted for its striking foliage and flowers. The leaves are leathery in texture and are deeply divided into narrow segments, creating a palm-like appearance. These leaves are a dark, blue-green color, which provides a striking backdrop to the plant's distinctive flowers. The flowers of the 'Yellow Wilgenbroek' are bell-shaped and hang in clusters from a single central stem. They have a unique yellowish-green hue, a subtle color that adds a touch of brightness to the winter garden when other plants are dormant. The flowers are edged with reddish-purple, which provides a delicate contrast and highlights their shape. Typically, these blooms appear in late winter to early spring, creating an attractive display against the dark foliage. The plant itself maintains a rather bushy form, dense with foliage and stems that bear the characteristic flowers. The stinking hellebore is named for the unpleasant odor it can emit when its foliage is crushed, a feature that is typically not overtly noticeable unless the plant is disturbed. Despite this characteristic, the 'Yellow Wilgenbroek' is desirable for its ability to thrive in shady conditions and its contribution to the garden during a time of year when few other plants are in flower. Overall, this particular cultivar presents a subtle yet refined beauty that can enhance the aesthetic of a garden space, particularly in areas where it can naturalize and form an understated but elegant ground cover.

WaterStinking hellebore requires consistent moisture, so water when the top inch of the soil feels dry to the touch, typically about once a week. During hot dry spells, you may need to water more frequently, ensuring that you provide deep, thorough watering to help establish a strong root system. It is less tolerant of drought than some of its relatives, so regular watering is key, with approximately 1 gallon of water per week, depending on weather conditions and soil drainage. Adjust the amount of water during rainy periods or if the plant is in a more shaded and cool location, as it will require less.
LightStinking hellebore thrives in partial shade to full shade conditions. This plant prefers a spot that is protected from the harsh afternoon sun, which can scorch its leaves. The ideal location offers morning light or dappled shade throughout the day, providing a perfect balance for this plant’s growth and flower production.
TemperatureStinking hellebore is hardy and can tolerate a range of temperatures, enduring minimums down to 0°F and maximums up to 90°F, though it prefers cooler conditions. The ideal temperatures for this plant are between 50°F and 75°F. It is a tough plant that can survive winter frosts and temporary freezes without significant damage, making it suitable for a variety of temperate climates.
PruningPruning stinking hellebore is mainly done to remove old, damaged, or diseased foliage and to maintain plant shape. Pruning in late winter or early spring, just before new growth starts, is ideal. Cut back last year's leaves to the base when you see the flower buds appearing, which cleans up the plant and makes the flowers more visible. Pruning too often is not necessary as this is a low-maintenance plant with a naturally tidy habit.
CleaningAs needed
SoilHellebore, commonly known as Stinking Hellebore, thrives best in well-draining soil with plenty of organic matter, such as a mix of leaf mold, compost, and perlite or coarse sand. Aiming for a slightly acidic to neutral pH of 6.0-7.0 will support healthy growth.
RepottingStinking Hellebores rarely need repotting and can remain in the same pot for several years. They should be repotted only if the plant has outgrown its pot or the soil has degraded, typically every 3-5 years.
Humidity & MistingStinking Hellebore is tolerant of a wide range of humidity levels and does not require high humidity; average room humidity is generally sufficient for this plant.
Suitable locationsIndoor
Place Stinking Hellebore near bright, indirect light and ensure well-draining soil.
Outdoor

Life cycleHelleborus foetidus 'Yellow Wilgenbroek', commonly known as the Stinking Hellebore, begins its life cycle when seeds germinate, preferably in moist, well-drained soil and some shade. After germination, the seedlings grow into juvenile plants with a rosette of dark green, palmate leaves. As the plant matures, it develops a thick, fleshy stem and reaches its adult form, which typically includes a taller stem with more leaves and sometimes multiple stems from the base. The Stinking Hellebore then blooms in late winter or early spring, producing clusters of nodding, chartreuse flowers with a unique, strong odor. Following pollination by insects attracted by the scent, the flowers set seed in late spring to early summer, which are distributed by wind and gravity. After setting seed, the plant might die back, especially if it's a biennial form; however, many cultivars are perennial and will continue to grow and repeat the cycle in subsequent years.
PropogationPropogation time
Spring-Early Summer
Helleborus foetidus 'Yellow Wilgenbroek', commonly known as Stinking Hellebore, is typically propagated through seed. The best time to sow seeds is in late spring or early summer just after they mature, ensuring a higher germination rate. To propagate, collect the seeds from ripe pods and sow them immediately in a cold frame or a shaded nursery bed since they are short-lived and do not store well. Cover the seeds lightly with soil as they require light for germination, keep the soil moist but not waterlogged, and expect seedlings to emerge by the following spring. Thin the seedlings to about 12 inches (approximately 30 centimeters) apart once they are large enough to handle. It is also important to note that germination can be erratic, so patience is necessary when propagating Stinking Hellebore from seeds.
