If UK weddings are anything like the US, you have a huge task ahead of you. Luckily, time is on your side, but not much. I'd advise to work with a local florist shop. They are worth their weight in gold. PS. Happy New Year!

I wrote to say more or less the same and then deleted it again. Our seasons are so unreliable it would be very dodgy to have to depend on garden flowers especially with restricted colours at that time of year. Roses could do it but you'd need a lot of plants.
You could concentrate on lots of attractive greenery(or silvery...) etc and order the colours flowers you need from the florist and let them worry about it even it it does work out a lot dearer. It will be worth it to avoid all the worry and lots of green and silver would cut down the number of flowers you need. You might beg some nice red Cotinus from a friend too if you're lucky.

If you would like an eye attracting contrast within your color scheme of orange and coral you might try adding a few blue flowers within your arrangements.

A warm gh would help!......but I do agree its a bit early, who knows what the rest of the winter and spring holds, the weathers so erratic....

Blimey, that's difficult to achieve, that particular colour range at that time of year, especially with all this peculiar weather we're having. I can only think of one plant that should be in flower then and through the summer if you start them off soon, and that's Eschscholzia, or Californian poppy. Not usually used as a cut flower because the stems aren't long enough, and once cut, they tend to droop, though there is a way to prevent that by making up a solution to put them straight into (if you're interested, I'll give you the recipe). They do grow taller in damper spots and in half sun, half shade though.

What a great response , thank you every one.
Hmm I wonder if I can change minds about colour schemes,even the time of year.
Great idea,using lots of foliage with some colour running through, might be easier on the pocket too.
Or perhaps an alternative to flowers who knows.

When you say the colour scheme is coral/orange is that the flowers or the frocks?

If it's the frocks you could think about white/cream flowers and then use ribbons to match the frocks.

One orange flower that may be available at the time is lilies (there always seem to be orange lilies in supermarkets). Otherwise - as someone has already said - make friends with the local florist.

Hello

I believe the bridesmaids are orange/ coral, so yes cream would be an alternative.
Is that going to be as difficult.

Lillie's are good and they are always available in supermarkets etc

Just to be different - I would search out a florist who sells silk flowers. They are expensive, very realistic, but can be collected every fortnight until the great day in various shades of coral and orange.
The bride can keep them to use in her future home.
Used in arrangements of greenery, even green plants,
they would look wonderful, especially echoing the colours
of the bridesmaids dresses.

p.s. I would find the silk flowers, work out the cost of the number of arrangements you have to do, and do a small
one to see how it looks in the venue, if they will let you.

I have been looking at silk etc flowers. I may get some as a backup.
Apparently I may be lucky with asiatic lilies, & alliums,I know the alliums are not the colour I am looking for but a few may be a nice contrast.
I am hoping to see more of the sun so I can get the lilies a good start in the greenhouse.
Thanks for all the ideas.

I love silk flowers, as they can be used very effectively with fresh flowers to make large arrangements. Nobody knows the difference.

You can get silk flowers by the truckload on Amazon.com. However, too many starts to look tacky. Nobody will be fooled.

I am getting so many answers to my dilemma , thank you all.
Silk & fresh that's a thought.
Thanks
