When I commented on how long his roots were, Mike told me that he uses tree pots. Tree pots are deeper than the average pot. On the note of whether he ever sends anything other than single fans, I remember only one time receiving a double fan. Every other time was a SF. If he only plants SFs in the pots and grows the daylilies in a minimally heated greenhouse, the daylilies don't have the heat and time to increase before shipping in the spring. The fans have always been a good size, actually surprisingly large coming from the north.
