Identifying a Fast-Growing Deciduous Shrub with White Flowers

A mystery shrub: 5 ft tall, 6 ft wide in one year, forsythia-like stems, small white daisy-like flowers, loses leaves in fall. Bought in a "flower pak."

Likely Shrubs

• Chionanthus virginicus (Fringe Tree) – best match: white fringe flowers, vase-shaped, fast.
• Viburnum odoratissimum (Sweet Viburnum) – white flowers, fast, but evergreen in warm zones.
• Viburnum rufidulum (Rusty Blackhaw) – white flowers, deciduous, native.
• Photinia glabra (Japanese Photinia) – white flowers, new growth bronze-red.

Possible Perennials (if "flower pak" means small pot)

• Artemisia lactiflora (White Mugwort) – 4–5 ft, white plumes.
• Digitalis purpurea 'Dalmatian White' (Foxglove) – biennial, spikes.
• Angelica archangelica (Garden Angelica) – 4–6 ft, white umbels.
