The case of the missing tulips . . .

I was so proud at the end of last season to plant some colour-coordinated tulip bulbs; alternating white and violet ones up either side of the front walkway. I noticed however, that everything seemed to come up o.k. on the left, but only one lonely one on the right. Figured maybe I messed up somehow, but then I caught a glimpse of where they ended up . . . I no longer think squirrels are cute 8 !
