请问论坛里有谁养过此品种吗？两年前在nursery被此花所迷惑，借巨款把它拿回家，精心伺候。去年长满了了花苞，可是一个一个的掉了，一朵花也没有开出来。今年我把它从前院移到了后院，移植时也挖了大坑倒了一袋有机肥，随时浇水，但是历史好像又要重复了，挂了很多的花苞，但是最大的那个变黑了，感觉又要掉了。

About Closed Magnolia Buds
When you see abundant magnolia buds on your tree’s branches, you’ll be hoping for a canopy full of flowers in spring. When those magnolia buds won’t open, the first things to look at are cultural practices, including the amount of sun and irrigation the tree is receiving in its current location. Magnolia trees need lots of direct sun in order to produce flowers. The more shade your tree gets, the fewer flowers you will see. Even if you planted it in a clear, sunny site, nearby trees may have grown tall and currently be shading it. If those closed magnolia buds are not getting much sun, you’ve figured out the problem. Likewise, magnolia trees don’t do well with too much nitrogen fertilizer. If you notice magnolia blooms not opening, check to make sure your trees get enough, but not too much, feeding. Magnolia buds set in the fall to open in the spring. During their wait, a lot of weather happens that can result in your magnolia blooms not opening. If winter weather is wet, the closed magnolia buds can rot.

Cold fall weather can bring frosts earlier than usual, before the buds are prepared for it. This can prevent flowers in spring. If the closed buds are falling from the tree in spring instead of opening, this may well be a sign of damaging spring frosts.
How to Make a Magnolia Bloom
If you are wondering how to make a magnolia bloom, there is no one secret to success. However, selecting a cultivar appropriate for your hardiness zone is essential. If buds on a magnolia don’t open for several years in a row due to weather, you might want to transplant your tree to a more weather protected area. You can also try using protective covering during frosts of autumn and spring. If you discover that your tree is in shade, you know why you see magnolia blooms not opening. You need to trim back neighboring trees or move the magnolia to a sunnier location.

我已经Google并试过了，还把它从fullsun 移到 partial sun. 去年没有施肥今年施有机肥了。Closed Magnolia Buds: Reasons For Magnolia Blooms Not Opening

也可能今年不开花跟你移他有关系，移的时候容易伤根，结果就开不了花了。如果你确定现在待的地方阳光土壤之类的正合适，就耐心等等吧。说不定明年就开花了。
一般magnolia有花苞时没有叶子的，开一树花，花后才长叶子，楼主这个虽然也叫magnolia,但看起来很不一样，没种过，不过如果长了花苞开不了多数是营养不够。

开花时间是在春天和夏天，花苞很容易受到晚季霜冻的影响，楼主是属于哪个区域？
今年5月魁省和安省都还有霜冻，是不是花苞被霜打坏了？
你这种木兰真太少见，我看到的一般都是开春就开花的，很少见到夏天还开花的。
是的这个品种比较少见，这次花也给我一个教训就是买花前先到左邻右舍去转转，一般大家都种的就是比较容易养的品种。我在多伦多，应该zone 5。花苞到现在为止都是长的不错，只是大了应该开花了，却渐渐就变黑了，和去年一摸一样。这个链接上说的是这种木兰花生长的区域是6，7，8，9区，Oyama magnolia - Fine Gardening

另外好像中国有这种花，叫天女木兰，是辽宁省花。
是哦，珍稀树种，天啊买这颗树要花多少钱？你说借了巨款？
夸赞的说法了
就我信了咯，开花别忘了拍给我们看@#!夸赞的说法了
我也盼啊
就我信了咯，开花别忘了拍给我们看@#!
