DENVER -- Valentine’s Day is just around the corner, and many people will be forking over big bucks for roses.

But do the expensive roses last any longer than the cheap ones? And is there anything special you can put into the flowers' water to keep them fresh longer?  We put roses to the test.

In our first test we bought five dozen roses at different price points from different places.
1) $9.99 at a supermarket
2) $29.99 online plus delivery and a vase
3) $49.99 at a local florist
4) $74.99  online plus delivery
5) $105 at local florist

We set the flowers up at the station and checked them every day to see which would last the longest.

By day 4 the flowers in the $105 arrangement were already starting to droop.

By day 7 that arrangement was completely drooped over and looked the worst to us.

The ones that looked the best were the $49.99 arrangement from a local florist.

The three others all had half of their flowers drooping, showing in our test, it didn’t matter how much we paid.

There was no correlation between expense and how long the flowers lasted. The $9.99 flowers weren’t the best, but they certainly fared better than the $105 roses.

Does Treating the Water Help Make Roses Last Longer?

In our second test, we set out to see if there was anything we could put into the flowers' water to make the roses last longer.

We bought six dozen roses from Le Grue’s in Denver.

We left one dozen in plain water.

To each of the other bouquets we added an extra ingredient.  We tested:
1) Vinegar and water
2) Clear soda
3) Vodka
4) Crushed aspirin
5) Flower preservative that florists give out.

These are all well published tips, but will they work? We set all of the arrangements up at the station and checked them every day.

By day 7 all of the flowers were looking pretty bad. They were drooped over, and many had dark petals.

But the ones that looked the best to us were the ones in the sugar and vinegar water.  Here’s how we would rank the results best to worst:
1) Sugar and vinegar
2) Plain water
3) Flower preservative
4) Soda
5) Vodka
6) Aspirin

Fred Niles, a designer at Le Grue’s, wasn’t surprised by our results. But his advice might surprise you.

He believes the best way to keep your roses fresh is to use plain water and change it every other day. “Clean containers, clean water,” Niles said.

According to him, if you follow that advice, your Valentine’s Day bliss may last a few days longer.
