Russian Olive vs Burton Hican
Elaeagnus angustifolia
Carya ovata x illinoinensis Burton
Russian Olive is a medium-sized deciduous tree that has attractive silvery coloured foliage with small yellow flowers that emit a fragrant sweet smell.
It is drought and salt tolerant, and works well as a shelterbelt species. Russian Olive can also be used to combat erosion.
Note: although Russian Olive is planted as an attractive boulevard tree in many northern areas, in warmer areas it can invade watersheds and is considered invasive. Please do some research and plant the right tree in the right place.
Burton Hican is a rare cross between Shagbark Hickory and Pecan. Most Hickory x Pecan hybrids are not reliable producers but the Burton Hican produces large crops annually (in warmer climates). The medium sized nuts fall in between the Pecan and Hickory and are known for having a great flavor. They are well suited to fresh eating, cooking, and baking with a good storage life.
Hicans will carry features from both species. The Hickory influence causes earlier ripening times while the taste and productivity come from the Pecan. The Pecan genetics also cause the nuts to have a thinner shell that is easier to crack and the pecan-like shape makes kernel removal easier.
The Burton Hican is generally considered self pollinating but having a second variety for cross pollination will increase nut production. They have been known to cross pollinate with other Hicans, Shagbark Hickory, and some Pecans. Nut production is expected after 7-10 years.
Note: Plant this tree once. Due to its large tap root transplanting is not recommended.
