Re: Dangerous Pine Cones
Seeds, and subsequently plants available mailorder on an occasional basis. This may not be one of those occasions.
Very nice pics! Shame about the amount of deforestation.
The birds are Penelope obscura (larger black bird with red chin), and Cyanocorax caeruleus (smaller blue bird with black head); the latter acts as a seed dispersal agent for the Araucaria.
I have some AraucÃ¡ria Angustifolia seeds and I was wondering if anyone had any luck growing it in the New York area?
Definitely not hardy outdoors in the New York area! It needs subtropical conditions.
I know they can be hardy against frost and even sometimes it snow in the south of Brazil but probably new york cold weather would be to much for them to endure..
I think they will tolerate temperatures down to about -7Â°C or -8Â°C. In New York it would get temperatures down below -25Â°C.
I have to say this tree is a lot tougher than it is generally given credit for especially here in the UK. I grew one from seed a couple of years ago and it stands out in its pot all winter with no particular protection. I live in north Wiltshire (zone 8/9?) in the UK.
I also planted a large specimen (about5-6ft) out in the grounds of the Arboretum I work at last autumn. It is the only example we have and I planted it in memory of my grandfather who sadly passed away last september. Anyway, it has survived the winter (all be it a mild one) and is romping away quite happily. Traditionally it has only ever been planted in the far south west of the country where the gulf stream warms the weather up. I sited mine in a lightly wooded area, predominently surrounded by ornamental Larix and with very little understorey plants. It is protected to some degree but not as much as some would have me believe it needed.
Southern hemisphere plants don't have to sit in cold frozen soil for weeks or months. They also don't have to endure the low humidity of Arctic fronts. There is more to it than minimum temperatures.
Don't rely on it long term, though. No-one has ever succeeded in growing a specimen to maturity in Britain, despite 180 years of trying. Not even in the far southwest.
We had one donated to UBC BG a few weeks ago - it had been growing in a outdoors pot the last several years and surprisingly held up.
Have seen a few small specimens produced in Seattle and vicinity, but am aware of no long-term successes with trees of substantial size.
"Extremely rare here. The garden at 4025 NE 110th St has one 9 years old, 5' tall. Others doubtless exist; it may be hardier than is commonly supposed; worth a try."

There are some Araucaria angustifolia at Bedgebury pinetum uk and they
came through the last winter.Bedgebury is also one of the coldest parts
of Britian.However the trees could have been grown from high altitude
seed.It would be interesting to try this tree in the colder parts of the uk.
Hardly a useful test, since it was the mildest winter since records began 350 years ago . . . ;-)
I ment the 2005/6 winter Bedgebury would have had -12c
The tree I planted was from Bedgebury pinetum (the sister arboretum to the one I work at) originally. The seed was wild collected at altitude by a friend of mine.
It is still very much at an experimental level but seeing as winters are generally becoming warmer and less predictable, perhaps we have had a breakthough after 180 years. My tree certainly got snowed on and experienced some pretty cold frosts. Could this species have been more susceptable to winter damp in the past, with the cold just finishing it off? My tree is in a very well drained position and is not exposed to any cold drying winds. Not giving up on the little guy yet!
I have a few Araucaria angustifolia palnted out here in Devon my largest is
7 ft the trees were grown from a few sources so the seed could have come
from different altitudes in Brazil.They get a lot of sun and shelter.If I were
to plant a few Araucaria araucana next to these trees I might get hybrids.
can u post some pictures of Araucaria angustifolia?
Please could you advise me how to post pictures on this forum I have a digital
camera here and may be able to feed photos from my camera to this websitesite.
when will u post some pics?
Greyspruce sent this image along to me via email:
Thanks for posting the photo thats a young tree of mine I have a few others
of the same species hope to get nuts
