This is the largest of the dills which can be enjoyed both as a flower in about 12 weeks or as an herb by snipping the fern-like leaves prior to flower set. Good companion plant for bug control as it attracts many beneficial insects and pollinators and is a host plant for the black swallowtail butterfly. 
 
Direct sow 1/4" deep in full sun after last frost.  Germinates in 10 to 21 days.
