Botanical name? 5-6' tall, leaves like celery or lovage, yellow daisy 1" bloom Aug. zone 5-6, part shade

I think this is considered to be an old fashioned plant. Never seen it in a nursery. Although tall it doesn't need staking. Can't find it in any of my perennial references. Leaves get progressively smaller farther up the plant. Color is more like butter than a lemon.Both botanical and common names would be appreciated. Got it at a garden club plant sale years ago, unnamed.
