Question
I am trying to find name of bush that grows very quickly...5 ft in one year height and 6 ft wide.  It has stems like a forsythia/wild and almost formless..same texture and look.  First year it had small white flowers, like Shasta daisy flower.  Loses all leaves in fall, like forsythia. I bought in a flower pak and do not recall its name.  Your help appreciated.  Thank you..Joan

Answer
These plants may fit your description:

Chionanthus virginicus/Fringe tree *My best guess*  This is a pretty cool plant.
Eugenia uniflora/Pitanga tree
Viburnum odoratissimum/Sweet Viburnum
Viburnum rufidulum/Rusty Black-haw or Southern Black-haw
Photinia glabra/Japanese Photinia; White flowers, but the leaves have more of a bronze/rusty red color

You got it in a flower pak you say?  May it possibly be an annual/perennial?  These plants above are used more as ornamental shrubs than "flowerbed" plantings.  Some other 搘hite and wispy" plants offered as perrenials, and may be what you are referring to:

Artemisia lactiflora/White Mugwort
Digitalis purpurea/Foxglove ?Comes in white: 'Dalmatian White'
Angelica archangelica/Garden Angelica, Holy Ghost, Wild Celery, and Norwegian angelica

Just google them for flower images to see if any match what you are looking for.  Hope it helps. ~M
