Australia's biggest flower company could be headed to the ASX in early 2021, as rising sales through major supermarket chains Woolworths and Coles offset a difficult few months when large events and functions were hit hard by COVID-19.

Lynch Group, which employs about 400 permanent staff in Australia and 800 in China, operates seven flower farms across the two countries in a business that generates about $50 million in earnings before interest, tax, depreciation and amortisation.
