Echinacea doesn't sound like a winter plant but I don't know the cultivar you mention.
The winter flowering viburnums, farreri, x bodnantense etc have a lovely scent also the winter flowering honeysuckles, Lonicera x purpusii and fragrantissima. And sarcococcas.
Snowdrops, Cyclamen coum and some of the crocuses are away very early in the new year as are some of the pulmonarias
