| Info | This is an incredible blue/green hosta with great substance! It is an OP seedling from Aristocrat. The leaves are beautifully shaped, long and gently wavy and they arch slightly downward to form a pleasing mound. Its name is a musical term that means a 'brisk and lively tempo'. Allegro flowers in mid-August with beautiful near-white flowers. It is a good grower |
