More than a year ago I had called ECHO and special ordered the tree. Echo can be found on the internet, and phone numbers and hours of operation Eastern Standard time are listed. Their citrus tree and other prices are higher than most places but they (ECHO) do good works in parts of the world that need help with food security issues. They are a Christian missionary organization.

The Red Lime itself can be a potted plant in a larger container. It blooms in autumn and the fruit is ready about 60 days later, depending on weather conditions and available water. They taste very much like a lime, except the skin tastes like a Kumquat, so the fruit has a wider range of uses than many of its close relatives limes and kumquats.

I hope this helps, they are difficult to obtain as it is a very "new" cultivar.
