Salsify and Scorzonera

------------------------------------------------------------------------
A deliciously delicate flavour, supposedly reminiscent of oysters and asparagus.   They look unprepossessing, a bit like underdeveloped parsnips, with an odd colour to boot, but they are quite superb.
* They will do best in a soil dug deeply in autumn, stone-free, and without adding manure (like carrots).
* Sow seed, 6 inches apart, in rows 1 foot apart. As they grow, thin to about 9-12 inches apart - don't bother transplanting the thinnings.
* Water in dry weather.
* And from mid-October, you can start lifting the roots, through to January or February.   You will have to dig deep to pull the whole root out - they are easy to break.
