The Rocket seedlings are heading up towards the light now and have just their seed leaves on (cotyledons) but soon we should see their first true leaf. When the leaves are fully developed we will see the plant’s characteristic elongated and lobed leaf. When the seedlings are big enough to handle I shall pot them up into a sunny position out in the garden. I want these leaves near the kitchen so that I can pick them for making delicious salads. The leaves have a wonderfully warm peppery flavour that rises up above other salad leaves.
