Which line in this excerpt from amy lowell's "lilacs" emphasizes consonance?

lilacs,

false blue,

white,

purple,

color of lilac,

heart-leaves of lilac all over new england,

roots of lilac under all the soil of new england,

lilac in me because i am new england,

because my roots are in it,

because my leaves are of it,

because my flowers are for it,

because it is my country

and i speak to it of itself

and sing of it with my own voice
