Quick Overview:

‘Abetwo’ is commonly sold in commerce under the trade name of INCREDIBALL. It was developed from and is considered to be an improved version of H. ‘Annabelle’ which was originally discovered in the wild near Anna, Illinois. It features larger globular flower heads than ‘Annabelle’ (to 12″ diameter with 4 times the flowers per head), with the added bonus of having much thicker upright stems that do not flop even if flower heads become soaked with rain. The densely packed sterile flowers on the flower heads of INCREDIBALL emerge lime green, but mature to pure white. Flowers bloom in early June for up to two months. Flowers contrast well with the dark green leaves.


Easily grown in average, medium moisture, well-drained soils in part shade. Tolerates full sun only if grown with consistent moisture. Intolerant of drought, with foliage tending to decline considerably in dry conditions. Plants may die to the ground in harsh winters. Bloom occurs on new wood, so plants may be pruned back close to the ground in late winter to revitalize and to encourage vigorous stem growth and best form. If not pruned back, any weakened and/or damaged stems should be removed in early spring.
