Hesperis matronalis Purple (Sweet Rocket)
Hesperis (or Sweet Rocket as it is commonly known) is one of my favourite biennials. Tall, sweetly scented and filling the garden with beautiful purple clouds of flowers, gently swaying in the breeze.
Sowing biennials is such a worthwhile thing to do as it will give you wonderfully early blooms the following year when the garden is crying out for a bit of colour again….and make the most gorgeous cut flowers. They look amazing in a vase alongside tulips, alliums and irises.
