Gypsophila, also known as baby's breath, forms clouds of tiny white or pale pink flowers. For decades it was the classic filler in bouquets; today it is also used on its own, in large volumes, for light centrepieces, arches and children's styling. It is available almost all year round, grown under glass or imported, and is inexpensive per stem.
It dries well, so it suits keepsakes and favours. It does have a smell some people dislike, especially in large quantities and in a closed room. The guide to christening flowers lists it among the most common choices; the one on how to preserve your bouquet names it among the flowers that dry best; the one on seasonal flowers explains why it is always available.
What to ask: how much you need for the effect you want, whether the smell will be noticeable in a closed room.
