Growing flowers for Wedding Bouquet

[FlowerPows]

I have offered to make my sisters wedding bouquet, she just wants quite a simple posy, I’m also making a couple of button holes.

I have made bouquets and done wedding flowers and large arrangements before but it’s sourcing the flowers as she wants some blue ones. This is in May. I’m thinking of growing some flowers, I have the space.

Can anyone recommend blue flowers that would bloom mid May, I will buy white roses at the time and raid various friends and my own garden for greenery. Plus I have a Lavender bush and think a few stems even not if in full flower may be quite nice in her flowers.

Camassiamajd forget me nots maybe? That’s a lovely thing to do for her.

If you don't have luck growing blue flowers then maybe getting white ones a few days earlier and putting them in water with blue dye to change their colour?

You could try cornflowers and nigellas but they might not flower in time from seed.
Perennial cornflower (centaurea montana) is lovely and mine flower in May- maybe you could buy a plant from a nursery.
But a lot depends on where you live. Up north, you might struggle.

A blue hydrangea plant. I work in a florists, we recently had some hydrangeas in that we're already in flower, they should last over the summer and grow fresh blooms. Lots cheaper buying them as plants than as cut stems too.

It's always dangerous doing wedding flowers because you cannot guarantee that they will peak-flower at the correct time. It's a good idea to take a belt and braces approach, with another belt and another pair of braces for good measure!
Thinking in terms of back-up plans, do you have friends and family who have bluebells or ceanothus?

You might be lucky with cornflowers but you are leaving it late!
Germinate them indoors and plant out when they are a few inches high.
You will need lots!
In fact if you have enough room to plant in big tubs or trays you could just put the whole thing out when the friars are completely gone.

Another back-up: muscari / grape hyacinth.

Just as a secondary thought as well , I harvested a lot of lavender for my daughters wedding, unless you want additional little bugs joining you , I found I had to treat it all with a bug killer .

Thank you all so much for all the information, she only announced she is marrying last week and it’s mid May. They are having a small wedding on a budget. Very good idea about the hydrangea I have one in my garden but it’s not blue, plus the food dye idea. I really like Lisianthus not sure if that’s spelt correctly and would maybe look nice with a few dyed blue with food colouring.

Thanks again for all the suggestions, I may make a fake good quality silk bouquet as a back up. Or alternatively make a fresh white bouquet and add a few blue silk flowers in.
