» Gay_Klok - Flowering trees
Barbara,I planted a Cercis [two actually] early in the adventure at "Kibbenjelok". They have been one of my failures - both have grown well but have never flowered. The first one is growing by itself with plenty of sun, the second one has a light shade.
Do you have any theories?

In response to message posted by Gay_Klok:I have only grown Cercis canadensis. They seem to need some age before they will bloom to full potential, but young trees will show a touch of color here and there at about three to five years. They fix nitrogen so may not need much feeding. Seem to bloom best in full sun, make wispy little understory trees in the dense woods with scatterings of pink along the stems. They are in full bloom here and are the dominant understory color since the Cornus florida have mostly died out. The combo though is incredibly beautiful when it occurs.
One other thought, is provenance. These trees are apparently more cold hardy from northern seed sources, so there is some local adaptation. I wonder if heat tolerance could be similar, with some preferring a warmer climate. I don't know if chill factor could affect blooming.... and Dirr lists them to zone 9 which is quite warm.

In response to message posted by Cottage_Garden:Thanks for answer, Barbara. We, in Tasmania, are cooler than zone9. It may be that.
I have my son [living in Bombay] here for 4 days and am finding it hard to get things done [for trip] We had a great dinner party last night [9 adults and 4 grandchildren [pre-fed] ] abd I went the whole hog with 4 courses and best china etc
My trees would be older than 5 years and grow well. Perhaps it is the coolness of our Winter temps. They would not get frosts where they are planted.

In response to message posted by Gay_Klok:Lots of fun!
The trees would not mind some frost, since Dirr rates them to 9 on the warm end, even if they are from a warmer (ie southern for us) source. They are very cold tolerant. I would think they need at least some cold weather. Maybe it is just too warm in their location?

In response to message posted by Cottage_Garden:A "mainlander" [Australian states] would laugh at that. They think we live with constant snow and ice because we are the closest land to the South Pole [and they are jealous of our clean, green and beautiful reputation!]
We do get it cool in the country garden in Winter and of course, our summers are not so hot as most of the mainland. I would think we are generally 7 to 8 zones but it is very confusing. I have seen our conditions [in Tassie] likened to coastal California ????
