I planted dozens of Narcissus 'Rijnveld's Early Sensation in the autumn of
2005 around our village monument. They made a splendid show in Feb/March
2006. This year virtually 99% of them haven't come up. I dug up the bulbs
and an odd one has a pathetic green shoot of a few inches and that's it.
What could have gone wrong? Would it be a mistake to plant more in the same
place?

I planted them at the same time along the foot of a Lonicera nitida hedge a
few metres away , and they are flowering OK.
