A Rose in my garden

A beautiful Rose;
with a scent that is of attraction;
yet thorny and dangerous;
A very beautiful Rose in my garden.

Picked with care;
handled with wary;
kept sacred for boasting;
yet very scarce.

Selective on grounds you grow on;
Dominant on the soils you favour;
Yet not possessive as weed;
A rose in my garden;
groweth far more than anticipated.
