Its Lucerne which in your country is called alfalfa. Its not the least bit
invasive.

it does have similar leaves, but the pods are not
at all the same (the pods of alfalfa curl and are
very tiny in comparison).

also the main stem is completely different.
alfalfa crowns and sends up shoots that have
leaves, this plant looks like asparagus when
it pushes up from below the soil (the crown
is below the soil level).

i have alfalfa in another patch.

while reading about alfalfa recently i learned
that it releases a chemical to prohibit it's own
seeds from germinating. which explains why i've
not been able to get bare spots to fill in even
after leaving the plants to go to seed. so yes,
i'd agree that alfalfa would not be invasive.
