T. brachyceras (now available commercially) is a small species that 
can be grown successfully in a 10-inch/25 cm diameter, deep pot, 
though it does better given more space. I don't know piliferum (I 
think that must be the right spelling, not piliphera; also 
polyphyllum, not polyphylum). The others are large-growing plants 
that would do better in a gritty soil in a deep raised bed, covered 
against excessive wet. I did not find T. tuberosum 'Ken Aslet' hardy 
in western Oregon, but no doubt winters are warmer in Wales where Tom 
lives. Other than piliferum, I can recommend dry summer conditions 
for all mentioned.
