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.

Plant Care Tips

Sow in June into seed trays and leave them outside as it will be too hot in a greenhouse for them….and your flower beds will all be full. There they can stay (potting on into larger pots if needed) until you plant them out into their final positions in September.
