I planted some seeds of Hesperis Matronalis also called Sweet Rocket or Dame’s Rocket, and the plants came up like grass in next to no time. I should have reacted to the advice on the packet ‘scatter thinly when sowing …..thin out as necessary. Plants will self seed in following years after flowering. Sow outdoors in May to June, transplant in autumn.’ Well now I have a veritable forest to prick-out and keep under cover until the frost goes.
Growing up to 3 foot high the open airy plant flowers in shades of purple and lilac to white.The fragrance is as sweet as a violet’s, and most pronounced in the evening. It looks good in a border or a cottage garden and is attractive to wildlife. Some plants may bloom until August but warm weather shortens the flowering period.
Treat the plant as a biennial although it can often be perennial. When established it can be invasive and seeds freely.
Seeds are available from Thompson Morgan Sweet Rocket
