Hellebores produce many seeds that can easily spread and create uncontrollable growth. Planting them near streams can exacerbate the issue as the seeds can flow with the water current. If planting Hellebores, be vigilant in removing new seeds and consider a spacious location with regular pruning to prevent dense roots.
Hellebores, with some varieties growing up to 18 inches tall and 24 inches wide, are known for their rose-like cupped or upward-curving flowers that cluster together. Despite their invasive nature, they remain popular due to their attractive appearance, especially when they break through the snow and bloom in the spring. Some species feature 2-inch blooms that add to their beauty.
Hellebores can be advantageous or disadvantageous to your garden, particularly if they are non-native. While they require minimal upkeep and can grow quickly, they necessitate extra effort to regulate their growth and expansion. Here are the pros and cons of incorporating hellebores into your garden.
