These dahlia tubers were grown in my own garden in Pennsylvania. You can specify when you want your tubers - no earlier than the last week of March and no later than the first week of May. Shipping is a flat $10.99 regardless of how many tubers you buy, but you must place your dahlia order SEPARATELY from your orders that you want shipped right away. I do my best to clean my tools between cutting the flowers from different varieties and between dividing the tubers of different varieties. All the dahlia pictures are my own!
