Rhubarb
Every garden should have at least one clump of rhubarb for early summer puddings.
Unwins Rhubarb is a specially selected variety called Victoria, that produces succulent pink stems with a delicious tart flavour.
Plant this herbaceous perennial in February/March and it will establish over the summer then die back to ground level in the winter. See our guide on How To Plant Rhubarb for more information. Next year the plant will regrow from the crown, with strong healthy stems ready to harvest in spring.
Your plant will produce tasty stems for the next five or so years and sometimes for much longer.
