Ok, someone from this forum kindly sent me some cara and pentland javelin seed potatoes. Me being me, when I planted them out I managed to take the labels of the boxes so although each type each all together I'm not sure which is which. Is there anyway to tell from the flowers or the leaves? or do need to have a dig around?
Have a look at this web site:

Cara:

Javelin
http://www.europotato.org/display_description.php?variety_name=Pentland%20Javelin
Both seem to have similar foligae but the tubers differ, cara have pink eyes and Javelin have white eyes.
