This  found gem is a short shrubby little plant to about 2 1/2'  tall .  It would be fine in a pot.  It has wonderful rebloom.  The  blooms  are cup shaped.  They are usually all white but can have a blush of peach or pink.  There is a strong, sweet fragrance.  I don't know how hardy it is but has survived my zone 7 winters with temps down to 4 degrees.  Will get some dieback from temps that cold.  The leaves are small,  rounded,  and prone to blackspot.
