Euphorbia
Euphorbia plants look like frothy clusters of airy flowers and tiny leaves. You may mistake euphorbia for traditional baby's breath, but these wispy, mounding plants are quite different. They're drought-tolerant, need no deadheading, are deer resistant, and bloom pretty much continually throughout the late spring, summer, and fall. The plant is native to North America and grows quickly, featuring frothy white flowers held above narrow, delicate leaves.
