off the top of my head dwarf tulips or miniature daffs but you would have to control the flowering, polyanthus or primroses may also work, I have a friend who wanted snowdrops for her february wedding -- it worked but caused a headache :o)

lily of the valley and what about cormous anenomes not sure about the timing of anenome blanda though. grape hyacinths too. then you could do sprigs of bridal wreath spirea/ wigellia in posey vases instead.

Anenomes and pinks/carnations can look neat and quite small on the tables and are easy to arrange as well.

If using small pots make sure they are not top heavy as compost could be messy if knocked over?

Thank Pamq, seaburngirl, Doctorbob and Drc726 I have taken on board all your suggestions. I was unsure whether spring bulbs would still be in bloom as these are such a great option. The mini daffs sounds wonderful and lily of the valley a great favourite, also the grape hyacinths. Actually each and every one sounds perfect. I have such a lot of organising to do so I am very grateful for all you kind friends for helping me. Love Sue x
