Biennial - fortunately.

The Foxglove that is not the Sarcococca.
       Alice's wee Prunus was "droughted to death" a year or three ago.  I know she liked scented plants; whence cometh the Buddleja alternifolia and the Sarcococca, to mention but two.
       So - by way of cheap (Cost-free) replacement last year, I replaced it with one of the multitude of Sarcococca seedlings; which surprised me by wanting to flower this year.  A search towards the centre might show you the Buds.
