Can someone help me analyze what most of these lines mean!?

A Tulip Garden


Amy Lowell





Guarded within the old red wall's embrace,


Marshalled like soldiers in gay company,


The tulips stand arrayed. Here infantry


Wheels out into the sunlight. What bold grace


Sets off their tunics, white with crimson lace!


Here are platoons of gold-frocked cavalry,


With scarlet sabres tossing in the eye


Of purple batteries, every gun in place.


Forward they come, with flaunting colours spread,


With torches burning, stepping out in time


To some quick, unheard march. Our ears are dead,


We cannot catch the tune. In pantomime


Parades that army. With our utmost powers


We hear the wind stream through a bed of flowers.
