It looks like a regular rose, but with close inspection you'll notice it's striped like a zebra. This hybrid was created to combine the commercial rose with the garden rose. There's some chlorophyll in them that cause a green tint, which creates an unusual look. These roses are not grown in soil, instead they are hydroponic roses cultivated in an artificial product. They have a long shelf life.
Roses drink plenty of water.
Cut the stem at an angle and as short as possible. This will enable the rose to receive plenty of water. The shorter stem is easier to pierce the floral foam with as well. When removing the rose foliage, cut at an angle. This will enable reuse of the foliage in the arrangement.
