Re: Lavandin vs. L. angustifolia


John or Olivier,
Thanks for the info, could either of you help me out
with easy ways to distinguish between L. pinnata and
L. multifida, which I always seem to have a hard time
remembering which is which.  I think it is L. pinnata
var. buchii which is one of my favorite almost
everblooming lavenders, unfortunately not fragrant as
most, but a great color accent.  Or is it L. multifida
that I am thinking of?  Don't they both have similar
foliage and branched deep purple flower spikes?
