I'm considering planting a row of trees primarily for their blossoms (I'm in rural Auckland - occasional temperatures are down to -4°C, typically high of 25°C in summer) - which leads to 2 questions.
Are there any easy-to-grow fruit trees which will have lots of blossoms for a long period like Cherry Blossom trees but also yield edible fruit?
How do clay soils fit into the picture, and how is there a significant difference in maintenance work to the trees ?
