If what you cut off was only the leaf, then the cane may still grow assuming it hasn't already reached maturity. If you did actually cut off part of the cane then no it will not grow anymore.
As far as blooming goes, that depends on the type of den. If it is a nobile-type (often refered to as 'soft caned' dens) it may still bloom on the cane as they can bloom at various points on the cane. If it is a 'hard caned' den then it is very unlikely to bloom as they typically bloom from the tip of the cane.
