In the garden, roses are grown as bushes, shrubs or climbers.
“Bushes” are usually comparatively low growing, often quite upright in habit, with multiple stems emerging near ground level; they are often grown formally in beds with other roses.
“Shrubs” are usually larger and have a more informal or arching habit, and may additionally be placed in a mixed border or grown separately as specimens.
Certain bush hybrids (and smaller shrubs) may also be grown as “standards”, which are plants grafted high (typically 1 metre or more) on a rose rootstock, resulting in extra height which can make a dominant feature in a floral display.
Climbing roses are usually trained to a suitable support. (source)
So can chinchillas eat rose stems?
Unfortunately they can’t at all.
They are too dangerous for them to eat and will hurt them if they eat them.
