Valencia Delta Orange Tree

The Valencia Delta Seedless orange tree is a late-season variety, a natural mutation of the Valencia Late variety discovered in South Africa.

It produces large quantities of beautiful, medium-sized navel oranges that are seedless (or have very few seeds).

The harvest takes place very late in the season (April, May, and even as late as June), which means oranges are still available in early summer.
Since the fruit remains on the tree all winter, this variety is best suited for areas with moderate frost.

The tree has no thorns, is quite vigorous, and is very productive.
