Conveniently-Sized Hazelnut Can Produce in 1 Year

Why Theta Filbert Hazelnut Trees?

It's a classic tree, now grown for optimal benefits. Not only can it produce fruit in its first season, under optimal conditions, but it's also carefree. What else makes the Theta Filbert a must-have?

  • It's a beautiful tree with large, thick green leaves.
  • It's resistant to pests and diseases, including Eastern Filbert Blight and tolerant of heat and humidity.
  • And it's conveniently-sized, topping out at 8 to 10 feet in height.

Experts at Oregon State University set out to engineer the perfect Hazelnut Tree, and the result was the Theta Filbert. Aside from the numerous qualities of the tree itself, the hazelnuts are some of the best we've seen. Gorgeous, glistening, copper-colored hazelnuts abound. Created to produce high yields, the Theta's nuts fill their husks in great numbers. What's more, the Theta's flowers will pollinate and help increase production in your Jefferson Filbert Trees as well.

    So far so good!

    The trees arrived a bit parched, but that was to be expected. American hazelnuts are tough trees. They are hanging in there, and now the dry leaves are being replaced by fresh green ones. I know they will grow to about ten feet tall and will look beautiful! I’m happy with them. :)

    Healthy trees, still alive!

    The trees arrived as advertised. They were healthy with some foliage. I have a brown thumb and was concerned if they’d still be alive. It’s been about month and they are doing fine.
