One leading supplier told Horticulture Week: "The run up to Mother's Day was slow. Light levels have been an issue and people have not been in their gardens. But last week, the gun fired and we've been inundated with retailers wanting product for Easter weekend.
"It's come a bit late but it's come just in time for us to clear spring lines before the main season kicks in."
However, some growers are known to have had to throw away primroses this season and have "suffered a lot" as large retailers have not had the sales expected, with cold and wet weather and the early Mother's day holding back sales.
The weather is due to change this week and high pressure moves on and low pressure moves in on the gulf stream, meaning it will be wetter, windier but slightly warmer for Easter.
HTA horticulture head Raoul Curtis-Machin said: "In general everyone is pretty optimistic. There was good sell through which warm weather accelerated. The cold snap came and things are back on track now. I can see cracking sales this Easter though the weather is the great unknown."
