The most obvious is that rose vibrators are made of silicone

The rose vibrator is shaped just like the flower, but it has several key differences. The most obvious is that rose vibrators are made of silicone, which is a very soft material. This means that they're great for people with sensitive skin or those who don't like anything too hard against their delicate bits. Another notable difference between real roses and these vibe flowers is color: most rabbit vibrators come in pink, red or white colors (and some are available in purple).The base of a rose-shaped toy will usually be flat instead of rounded like an actual flower stem would be; this makes them easier to hold while you play around with different stimulation modes on the toy's surface. A lot of these toys also have multiple petals along their outer surface—especially when compared to real roses—which may give you more control over how much of your genitals get stimulated at once when using them as dildos (but not all do). Most also have a rounded end like an actual flower head might have; however some models feature smaller nubs or bumps instead as well as other shapes entirely!
