Neutral Sequoiadendron4 On Mar 25, 2015, Sequoiadendron4 from Lititz, PA (Zone 6b) wrote:

I'm not a super big fan of the specimen we have. It was planted summer of '12 and did fine that summer. The next year it grew great but we had a drought late in the summer and I didn't start watering it until the needles showed signs of stress, I guess that was my bad but it lost a lot of needles and barely made it. That winter was terrible harsh and burned out some more needles and it lost the leader. Spring of '14 it put on some new growth and hung in there but was otherwise unremarkable. This winter has some of the needles burning out again and I'm really questioning the hardiness of zone 3. For me, it seems like it's barely hardy in zone 6 and it's not in an over exposed location either. It's a shame I've had so much trouble with it because it could be a very nice plant. My patience is wearing thin and it has this season to straighten up or it might get edited in favor of something more durable.

Easy container plant.

We waited 3 years to find the right specimen of this plant. They are infrequently offered here, and usually have very contorted trunks. We wanted a tall tree (eventually), not an ornamental garden accent. We finally found the right specimen with a nearly perfectly straight trunk. Three years later, it is doing fine, growing steadily upward, and filling in nicely.

New needles do not show the variegation. It appears during summer in full sun - dark green with bands of yellow.
