I first started growing Rocket about 4 years ago. I thought that "wild rocket" sounded the most fun - and it was. It grew to a large bush about a metre in all directions. The leaves were if not hot, very warm and spicy. You're supposed to use them in salads but after buying some roast beef and rocket sandwiches in a shop, I decided to go for home made.
A bit later in the summer, there was another bonus. Small, sweetly scented yellow flowers. My garden is fairly enclosed so on a sunny day the smell met you on the path. The bees liked them too, which is another environmental box ticked.
This year, a bit of a set back. I'd bought in the beef, bread and butter before wandering down the garden for the Rocket. It just wasn't there. Not only the main bush - even the self-sown seedlings had vanished. Now, I was used to Rocket dying back in winter but by early summer, I just assumed it would be back. The very sharp frost we had last winter had taken it out.
Went down the garden centre for seed. This time, decided to try a variety called "Skyrocket" which claims "the speed of Salad Rocket and the flavour of Wild Rocket" Initial tasting is good - I know this sounds like posing but the flavour has both strength and complexity.
And, just in case of a cold winter, I'm keeping a pot under cover :-)
