So...you're looking for a gift for Aunty Violet, who has a million and one vases scattered around the house, and your eco-vase is going to do absolutely nothing for her apart from gasp at the sight of it!
Your other option is to go for a traditional bouquet, that's arranged in a way that she can see all the stems, can unwrap it, cut, prune and preen in any way she likes in the vase that pleases her.
VIOLA, job done!
