Helleborus abruzzicus refers to a population of Italian plants that have only recently been described. These are very exciting plants with highly divided leaves and leaflets. Leaves may be divided 100 or 200 times forming a lacy mound of foliage in mature plants.
They occur in substantial populations in central Italy northeast of Rome (Lazio, Abruzzi, Umbria) at elevated sites above 1000 meters. A recent article by Mclewin, Mathew, and Thomsen has proposed that these plants may deserve consideration as a new species. These plants are winter dormant and later blooming than Helleborus bocconei or Helleborus liguricus and offer great potential for continental climates.
Whatever the outcome, these plants represent an exciting contribution to horticulture. Their hardiness and unique form, combined with the possibility that they are more vigorous and robust than other plants of similar morphology, gives all those interested in hellebores a reason to pay them close attention.
