Indoor Pot plants for May

Hi Maybride, welcome to GOY, you are planning well ahead for your big day. You will get lots of answers on this one I'm sure, here are just a few ideas.
Try Anemones, there is one called The Bride.
De Caen singles. St. Brigid Doubles.
Scilla Campanulata.
Muscari.
Plant in the containers you are going to use in bulb fibre, these can be grown out of doors, late autumn till April. Cover in frosty weather, they should be ready in May if your season is normal.
Best Wishes.

~ check the avon bulbs site-they have a whole range of bulbs ~ and may be able to put together a list for you~ what about lily of the valley which should smell gorgeous!
I would be tempted to plant quite a lot in case the timing goes off track-but don't forget most of the garden centres will have flowering bulbs you can put into your own containers if all else fails!Our local florist had some spectacular early spring containers!
