The Welton-based company recently launched its new catalogue containing 700 varieties from four countries.
Partner Lee Ford said that early demand was showing that people are keen to grow different vegetables and herbs.
He said: "We think the popularity of our seeds is down to the fact that more people want to grow more of their own food. They are enthusiastic about non-standard varieties."
Peppers and herbs have both had strong sales he said and okra and squash were also doing well.
The three-year-old company has a delicatessen range which Ford says has proved very popular.
He attributed the popularity of celebrity chefs Jamie Oliver and Gordon Ramsay for their success.
The new catalogue contains German varieties as well as French and Italian.
Ford said that more and more European producers were looking for a route to the booming UK markets.
