No, a tree is a plant.
There are several different species of lysimachia (Lythrum salicaria ), which is of the Primulae family.
A plant growing under the tree will not have enough sunlight for photosynthesis hence it will remain smaller than those plants growing in open fields.
Lysimachia, commonly known as loosestrife, includes several species, some of which are native to the northeastern United States, such as Lysimachia nummularia (moneywort) and Lysimachia vulgaris (yellow loosestrife). However, other species, like the invasive purple loosestrife (Lythrum salicaria), are not native and can disrupt local ecosystems. Overall, while some Lysimachia species are native, others are introduced and invasive.

Lysimachia has a reputation for healing eye ailments, and is said to be able to restore sight in certain conditions. Some practitioners say it is superior to eyebright for these purposes.
Plant it about at least 3 meters away so that the tree roots have space out under ground without being tangled by the roots of a flower.
