I grow one, 3 meter high, 5 meter away from my house (France Zone 8, mediterraneen climate) and every year in the middle of July the scented white flowers appear until september. Last year about a hundred! Ofen the young growth freeze but it regrows quickly. Some spines on young branch. Nice plant!

As noted on my photo, I grew my tree from seed (which I received in a swap on DG.) It froze to the ground the second and third year but the fourth and fifth years have been uninterrupted by a freeze. I think it is large enough now that though it may have some damage from a hard freeze, I doubt it will freeze all the way to the ground. I had one or two blooms in other years, but this year 2013, it is significant!!! Im having difficult;y growing dogwood here due to the heat so I think this may be my new dogwood. The trunk is about 2" in diameter now and it is covered in blooms.

Beautiful white flowers cover this tree in spring and fill the air with a sweet clean fragrance. In bloom about 3 weeks then it forms large green seed pods that turn dark when seeds are ripe. The pods uncurl and drop their seeds which sprout quite well. This tree is cold sensitive and is damaged by the light freezes we get here in Central Florida but it will grow back quickly.
