Here's a few suggestions for your wedding cutting garden: gladiolus, salvia, lilies, and iris. You should probably plant more varieties than you might need so that you are sure to have enough. It's hard to predict when flowers will bloom in any garden. I hope that you have a good friend who can do the cutting and arranging the day before (there's some preservative you can use, I think). You'll probably have more than enough to do.

I grow mostly perennials and woody plants, but do have a few thoughts for you.

Zinnias will grow and bloom quickly, but I find the water turns very smelly after just one day; so if you're going to arrange them the day before the wedding, that's a consideration.

Cosmos also grow quickly, make good cut flowers, and should give you masses of blooms in colors ranging from white through pinks to deep red.

Snapdragon is another quick grower, blooming in late spring to early summer.

I hope someone will chime in with more suggestions for you. If not, perhaps try the Cottage Garden forum - there are lots of very friendly and experienced gardeners there from all over the country ... there's bound to be someone who grows annuals in your climate.

Don't forget fillers (like baby's breath, gypsophila) and greens - you can choose from solid or variegated leaves, smooth or rough textures, large & bold leaves or long and narrow, even trailers like ivy, whichever best suits your arrangements and your fancy.

A trusted friend to help with the arrangements sounds like a good idea. Have a wonderful time with the preparations and best wishes on your wedding day.
