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
