|I recently bought a house with a garden that was begun in 1929. The woman who planted was a perennial freak (for which I am grateful) but I'm afraid to pull any "weeds" for fear they are just perennials gone astray. In particular, I have several plants with fern-frond-like leaves and white flower-heads with numerous little flowers on them. It is not Queen Anne's Lace, as I know that flower. The leaves are softer and fleshier. The most distinctive attribute is that the leaves, when crushed, smell strongly of anise. What is this plant? Any ideas?
