Ecuador roses tend to be larger, a result perhaps of the altitude and environment. Talking about other flowers than roses, Columbia they have some fantastic exports that I do enjoy using. Now talking about the Dutch roses, and we are in a different ball park. More Dutch roses tend to be more expensive than the South American varieties. From my ordering experience, the roses tend to be far smaller, but more intricate in petal depth and detail. The stems are not as hearty and stiff as the South American ones, but to each rose has a purpose. Dutch roses , at least I have found, work really well in high detail bouquets, where larger South American roses, because of the size, would overpower the bouquet and leave a bit of a jumble. It just depends on the look you want to have.
Now I can almost hear you ask the question "What about American Farms, where do they fit in?". Well we do have them, California is fantastic in having rose growers in abundance. But as with all things made here in the USA, they can be more expensive than our South American imports. It is sad but true. The quality is top notch though, and the adage "you get what you pay for" is certainly true in this area. The Dutch roses as well as the North American roses are some of the highest quality you can get. Alas, at this time there is no FDA for flowers as there is for beef. Roses are not stamped with "Grades" A, B, C or D. Some areas, such as the EU, specifically Germany, have started doing such a rating system. Through the FLP (Flower Label Program) they stipulate that certain conditions must be met in order to qualify into FLP certified. These conditions range from wages paid to farm hands, conditions that they work under, pesticides that are used and the quality of the blooms.
