Pictures of Sequoiadendron Growing in NJ, NY and PA
Pictures by Greyneedle. Pictures taken 2003.
(Information Provided is for Recreational Purposes Only--No Liability Assumed)
There are three Redwood species:
Coast Redwood (of Redwood Forest fame and lumber): Sequoia sempervirens
Dawn Redwood (Chinese native, deciduous and similar to Bald Cypress in appearance):
Metasequoia glyptostroboides
Giant Redwood/Giant Sequoia (Big Trees of the Sierra Nevada interior, Yosemite and Sequoia
Natl Park): Sequoiadendron giganteum
In the NYC/Philly Area, Metasequoia grows easily, Sequoiadendron grows grudgingly and S. sempervirens generally
will not survive our winters. S.s. is seen growing in coastal Maryland, Virginia and DE (borderline zone 8 areas).
There are some tricks to growing Sequoiadendron in the area, so this site is dedicated to those interested.
The first order of business is to document that they can grow in the area and examine how well:

The Grand Tour and Wigwam Tree near the Hartshorne Woods and Twin Lights
State Park, Navesink/Atlantic Highlands NJ. Largest Sequoia in NJ at 65ft.
Heavy foliage. Appears healthy. Original top apparently lost (was apparently
taller). Zone 7a/Coastal. This is very near the Atlantic coast and the
Navesink river. Photos taken late April 2003. I talked to the homeowners. They said the tree was originally brought from California by the previous owners in a bucket in 1952 by car. It was probably 2' tall at the time (my guess), so that would make it about 53 years old or so. They said that people from the state "registry" come by regularly to measure the tree and that the homeowners are not allowed to do any pruning (I don't know why). I did not ask about the lost top. |

The tree's top appears to either have some phomopsis blight or winter burn. The lower portion of the tree is surrounded by juniper bushes, which are hosts of Sequoia diseases. The tree is also shaded to the south at its base by tall pine trees across the street. |

The tree may no longer be structurally sound after losing its original top several years ago. The reiteration is coming from the top of the snag portion of the tree along will all the major branches. The tree is leaning forward to handle the weight but the juncture is under a lot of twisting stress from the weight being so far off-balance. With a strong wind the whole top and all major branches could come off. This suggests that the tree is in decline. The homeowners may wish to cable the major reiteration to the trunk better to alleviate stress. |
The New Jersey Botanical Gardens at Skylands Manor. June 2003. They have two "Hazel Smith" Sequoias and this is the larger of the two. It is perhaps 50' tall. It was probably planted from a cutting in the late 1960's to early 1970's. The site is partially shaded by spruce and deciduous trees. This view is a composite image. Zone 6b/rural. Heavy foliage. Appears healthy. Soil silty/loam. | Sm Med |

Here and the next two photos are close-up of the foliage of a "Hazel Smith" Sequoia, which can be distinguished from the species and "Glaucum" by very blue-white foliage with sharp, pointy needles that are stiff. On "Glaucum" the foliage is adpressed more to the branch, whereas on HS the needles stick-out. "Glaucum" is blue-green in color as well, with a more pyramidal habit. The species has fairly green foliage that is soft and less waxy than HS. The disease resistance of HS seems to come from its ability to shed foliage readily. | Med Lrg |

Here is an extreme close-up. | Med |

Here is an alternate view with different light. | Sm Med |

The tree is producing cones! From a distance they look blue-white before maturing. There were lots of cones on the bigger tree and none on the smaller tree (see below). This suggests that HS can be bred with Glaucum or the species at some point. Of course, with only two HS on the grounds, this tree is not producing viable seeds. There is time to plant another tree though... | Med |
|
Here is a close-up of a mature HS cone that was found near the base of the tree. With proper academic credentials you might be able to ask the NJ parks service for a specimen. | Sm Med |

Here is the second HS at the NJBG. It is about 30' to 40' tall and looks healthy, with some diseased foliage near the base. It is not producing cones. It is about 100 yds away from the other HS but not labeled. |
Willowwood Arboretum 'Hazel Smith' sequoia, Longview
Rd, Chester, NJ. Large public facility. 8'. Zone 6a/rural. Shale/silt/loam.
Newly planted (grafted). It appeared healthy last year but this year is
seems to have suffered from last year's drought and the cold winter. It
is growing among weeds and is suffering from severe foliar blight. There
is a second, much smaller HS nearby that is also diseased. Photo taken in
July or Aug. 2003. When checked early Nov. 2003 the diseased foliage had
not dropped off as it had at NJBG. The foliage was also much greener than
most HS foliage I've seen. This may indicate an odd soil condition or issue
with the scion selection. Hard to locate on the vast property of the Willowwood arb. Newly planted in area set aside for recent acquisitions. Very weedy and buggy terrain. The coldest location for a sequoia among those I've seen. |

The second order of business is to see how well seedlings grow (see seed germination experiment links below):

Here is one of the two remaining seedlings from my spring 2002 seed germination experiment as it appeared in April 2003 when it was 1 year old. It seems to be partially immune from fungal diseases but is somewhat slow growing. 2003 was a fairly rainy, cloudy and cool year, unlike 2002, but the seedling did not seem to mind. In fact, cool rainy summers seem to suit sequoias fairly well if not too extreme. |

Here is same seedling in Aug. 2003 at roughly 17 months in age. It has a very bright red trunk! It will probably have to be transplanted fairly soon into a larger container. |
This seedling germinated in July of 2002 and was situated in a small plastic container on a somewhat sunny windowsill for the next year. It grew very slowly. It grew towards the window, making it bend severely. It was chronically overwatered in the spring and died in the summer of 2003 (see page with disease photos). Photo taken in March 2003. | Sm Med Lrg |

Here are the two windowsill seedlings. The left is (or was) very slow growing and the right was very vigorous. Note the very blue foliage, which results from lack of environmental stress (retained wax on needles). The seedling on the right desperately needed transplanting in Aug. 2003 since its main roots circled the bottom of the plastic cup several times. It was transplanted into a much larger container with the roots in mineral soil. Photo taken in March 2003. |
These are the seedlings that were germinated in large 18" by 3" tubes. Here they are in June or July 2003. Not particularly large yet. They grew more vigorously in August and Sept. (See the website on diseases for a photo from Sept.) | Med Lrg |

Even though the tubes are 18" long, the roots still grew out the bottom! By September they were growing from one tube to another! Trimming roots can work. The white is the polyester fiberfill that holds in the soil and provides "well drained" conditions at the bottom. A crisscross of wires at the bottom holds everything in place. When snipped, the soil would be free to come out the bottom into a planting hole. When using tubes, make sure the tubes have a split in them lengthwise to allow the soil to come out when transplanting. The split can be held together with tape or string until transplanting. A split along opposite sides will allow for maximum ease of transplanting. |
This special seedling was the only one of perhaps 200 seeds to germinate after being left unattended in soil here in NJ and then survive the summer. It was "discovered" by surprise since it had been a few months since I last checked on the experiment. I had thought that none of the seeds were going to germinate, but wet conditions in June, perhaps, caused this to happen. In this particularly dry spot of ground the seedling did not have to compete with grasses and weeds, which made matters much easier for it. Given the fact that HS produces cones and this seedling developed, it is slightly possible under unusual circumstances that a native tree could be born of parent trees here. | Med Lrg |
