Hey all! Does anyone know the average cost for midnight blue shrub roses? I think I will need about 50 stems - no arrangements, just the stems. I'm just not sure if they are prohibitively expensive or not... Thanks!

I am in love with this centerpiece idea but am having a really hard time finding where to buy the wood base. I'm honestly not even sure the best way to search for it/what it is called. I love the fact that it's finished, but looks like natural wood....
