Trying a few root crops

[Uli]

Troopaeolum tuberosum is a short day plant and comes from high elevations in the Andes. Both factors may explain the sucess and failure in different years.  They will only start to produce tubers after september 21st (Equinoxe) which in general is not enough time to produce big tubers before frost strikes. The high elevation origin means that the plants do not like hot summers. In England the heat problem is not really present so you can see Tropaeolum tuberosum 'Ken Aslett' in full lfower. here in Portugal none of the tuberosum forms perform. The winter growing Chilean ones do well, though.
