I took this picture from my kitchen window
One of the last trees to color up is our ornamental pear tree, Pyrus calleryana 'Chanticleer', which I look out on from our kitchen window. It is beautiful in spring covered with white flowers, has glossy leaves all summer, and right now, it glows in the November gloom. This tree produces small, greenish-yellow fruits that aren't edible and don't have much ornamental interest either.
Here's what the Missouri Botanical Garden site has to say about ornamental pears, and this cultivar in particular:
In the 1950s, callery pear emerged in U. S. commerce as a promising new ornamental tree, leading to massive landscape plantings. By the 1980s, concerns about both overplanting and structural weakness (limb breakage from wind, ice and snow) began to surface. ‘Chanticleer’ (synonymous with and also known as ‘Cleveland Select’, ‘Select’, ‘Stone Hill’ or ‘Glen’s Form’) is considered to be one of the best of the cultivars currently available. It is a tight, narrow, pyramidal, thornless ornamental pear tree that typically grows 25-35’ tall and 15’ wide. Some specimens appear almost columnar in habit. Oval, glossy dark green leaves dance in the breeze due to long petioles. It is susceptible to limb breakage or splitting from strong wind, snow or ice, but is much stronger than some other cultivars such as P. calleryana ‘Bradford’.Most of the trees we have planted on our property are native oaks, maples, ashes, pines and spruces, but close to the house I have planted a few ornamental pets like this pear tree. So far, so good: it's beautiful year round - it has glossy leaves in summer and a nice branching structure in winter - but I particularly love it covered with flowers in spring, and right now, as it glows with exquisite color.
