Asparagus Crown CollectionGrowing asparagus in your allotment garden is a long term commitment but the results will prove well worth the effort. At Mr Fothergill's, you can find two green and one purple variety of asparagus. Our collection of 10 crowns of each Cultivar includes the vibrant purple Erasmus, the easy to grow Backlim and the Dutch hybrid Gijnlim. With a high yield, we're sure the long harvest period will be well with the wait.
