Hey all, I'm going in for a consultation with a florist next weekend to try and figure out what flowers I am going to order for our DIY bouquets/centerpieces.

I am growing my own lilies in a variety of colours but I need to decide on some fillers (greenery/complementing flowers etc) to go with them. I only have to make 2 maybe three bouquets (one for me, one for MOH, one for a maybe BM who is still undecided), so it's not going to be a huge hassle. 

Here is what I plan/hope to use for myself as my 'main' blooms *crosses fingers that >50 days is enough for bloom time* (omg sorry these are so huge :O )

My MOH has decided on orange asiatics & tiger lilies (I let her pick from my garden what she wanted), so now I just have to wrap my head around what to fill out the bouquets with.

For some reason my brain seems to think white roses will be cheapest/easiest to get (but I really have no idea why I think this or where the idea came from haha), but I do also like to look of dahlias. I know it mostly depends on what is in season etc but I'd like to go into the meeting with a few ideas at least.

So, what would you pair with lilies oh-ever-knowing hive?

@LindsayB:

Thanks for the examples!
