ROSES: Discussing the Differences
We have received many questions regarding the different sizes of roses that we offer and the characteristics of each size. In an attempt to distinguish between the different sizes or grades of roses we have assembled the following information:
Why are many roses marked in terms of centimeters (cm)? The majority of roses delivered in the United States are shipped from Colombia and Ecuador. These countries are known world-wide for their stunning fresh cut flowers - especially roses. Colombia and Ecuador both use the metric system for calculations. When flowers are harvested they are sorted by size or stem length. Below are the most common conversions for these flowers:
40cms = 16 inches
50cms = 20 inches
60cms = 24 inches
70cms = 28 inches
What does the stem length mean? If you were to see roses that were classified as 40cm roses, the stem length of those roses would be 16 inches. This length is not indicative of the overall length of the flower, but rather of the length of the stem itself.
Aside from the roses being offered in different lengths, are there any differences in the actual size of the rose? The general rule of thumb for roses is: the longer the stem, the larger the rose head. Many flower farms grade roses by first measuring the size of the rose head. Based upon the rose head size the farm will cut the flower to the corresponding stem length.
Why are some roses larger/smaller than others? Part of the difference in size is a direct result of the length of the stem (again… the longer the stem, the larger the rose head). However, there are exceptions. Rose head size does vary by variety. Some varieties of roses tend to be larger/smaller than others. Each rose variety has unique identifying characteristics. These characteristics include color, bloom size, lengths available (not all roses are available in all lengths) and number of petals.
