Pinus strobus 'Green Twist' / Eastern White Pine

Pinus strobus 'Green Twist' is a dwarf, globose selection of eastern white pine with tight branching and fluffy, twisted needles. After 10 years of growth, a mature specimen will measure 20 inches (50 cm) tall and wide, an annual growth rate of around 2 inches (5 cm).

This cultivar originated as a witch's broom found in 1997 on a specimen of Pinus strobus 'Contorta' in Bickelhaupt Arboretum, Clinton Iowa. Bickelhaupt Arboretum Horticulturist, Dave Horst is credited with the find. Of all of the dwarf 'Torulosa' - type pines, 'Green Twist' is one of the smallest, readily available selections.

Is the Pinus strobus 'Green Twist' deer resistant?

David Olszyk

Hi Denise ... 'Green Twist' is no more or less deer resistant than any other white pine. It all depends on your individual situation. Deer facing starvation are known to eat nearly everything.


The twist part has turned brown. The pictures I have seen are green- Is my green twist white pine dying-

David Olszyk

the newest needles are always green. In mid- to late-summer every year, a portion (sometimes up to 30%) of the older needles will turn brown and fall. If this year's needles are brown, your plant has died.

My new 5 gal pinus twist was planted on the south west corner of my border bed and haz turned 80 percent brown. I have a drip irrigation to it every morning at 5am. Is it dying? Is it getting to much sun here in Mississippi. Do i need to move it to get just morning sun? Pleasee help before I lose it. I planted it in April land looked good til mid July

David Olszyk

unfortunately if it's 80% brown, it's probably already dead. Spring is the 2nd worst time to plant a tree (only summer is worse). A 5-gallon plant is going to be a little tougher to get established.

It's possible that you overwatered it. Did you check to see if the soil was dry 2 inches below the surface before turning on the drip system.

This plant does best in full sun, but thrives in the Northern U.S. and Canada where summer days are a bit cooler.

When I have a new plant , I water by hand so I'm sure it gets watered thoroughly .
But just as important is to allow it to dry out between waterings
So about 2 gal. , once a week
your plant is either too wet , or too dry
