Bloom and doom / Beverly Allen.

Enhanced descriptions from Syndetics:

As the co-owner of The Rose in Bloom, Audrey Bloom creates magnificent flower arrangements for brides to be. Though helping to plan a wedding can be stressful, it's nothing compared to the groom turning up dead.

A designer of eye-catching bridal bouquets-many of them based on the Victorian meanings behind each flower-Audrey Bloom is used to celebrations that end with happily ever after. In fact, every couple she's worked with is still together, living in wedded bliss. But her perfect record is about to be broken.

Her childhood friend Jenny Whitney has reeled in the most eligible bachelor in Ramble, Virginia, and she's hired Audrey to design the bouquet. But before Jenny can walk down the aisle clutching her blend of anemone, scabious, and pussy willow (a floral disaster in Audrey's mind), the groom is found dead-sprinkled with bits of a bouquet. This is bad for business-not to mention for Jenny, who has become the prime suspect. So Audrey decides to do a little digging herself, hoping she won't be the next Ramble resident pushing up daisies...
