Our base price of $15.00 is for 12" to 18" trade gallon size azaleas. Most azaleas are available in that size and price, however some times we sell out and only have larger plants from $24.00 for 18" to 36"+  to $39.00 for 3 gallonPlants. Three gallon azaleas have to be picked up at the Nursery, as we do not ship those. Also some azaleas in 8" mum pots that are heavier 14" to 18" plants are $18.00.
