We have this plant along our driveway on a 60acre property and just love them. Have never noticed the smell but they are not really close to our house however we do walk around with horses etc and have never smelt them.

anyway ours are 6 years old and our neighbours are 11 years old and so far so good no splitting they have for us grown very fast and look spectacular various times of the year.
i love that there are 4 distinct looks my favourite is the blossom then the colours in winter.

We have 2 out of 70 that are suckering along the root but all are well otherwise.

I will put up some pics for your perusal if they are allowed,

In Australia they have 3 names that i know of
Pyrus calleryana 'Glensform'

I concluded that this tree is an inferior ornamental long before I found out that it's invasive.

The lifespan of a callery pear is typically 10-15 years, with luck perhaps 20. (Dirr) I can't count the number of callery pears I've seen split and disintegrate before reaching maturity, because the tree's architecture can't support its own weight, especially in windy, snowy, or icy weather. Since 'Bradford', many cultivars have been released which are claimed to have stronger architecture, but they all have this propensity to splitting, and in the landscape I still see few surviving into maturity.

The flowers are pretty and very early, but they have a powerful pervasive stink.

The foliage is attractive and rarely troubled by disease. Fall color is g... read more

Three of these ubiquitous trees were planted in front of our home 17 years ago. "Like a Bradford Pear" we were told, "but they don't split". Their slender columnar shape soon changed to large and dense ;blocking views of our home. When the pretty white blooms appear, we can't open our front windows or enjoy other flower fragrances because they fill the air with the odor of a dead animal. Their seedlings invade, in massive numbers, the flower beds beneath them. Birds enjoy them, but the fruit goes right through them and ends up all over our cars. For a long time in fall and early winter their fruit falls and quickly turns to mush on our walkway. Now they are starting to split. These pesky trees will soon be gone.

This cultivar is similar to the popular Flowering Bradford pear tree, but is less likely to split and has a much narrower form (shape is like a tall pyramid). Autumn color is gorgeous as leaves turn a deep red - purple shade.

In spring, creamy white flowers appear all over the tree. Very neat ornamental (specimen) tree.
