Pick the healthiest specimens offered and you're good to go.
And while my 'organic terrorists' brethern will definitely dis me for stating this but if there is a specific cultivar and while it may have been grown into a 'start' - I'll still buy it.
For the pitiful amount of 'non-organic' soil it's hardly worthy of note. Get the strain. Grow it. Take cuttings. Get them organic.
