Invincible is one of the hardiest pear varieties, good for difficult situations which other pears would not tolerate. The fruit can be kept for a few months in store.
The flavor is not quite as refined as Comice, which is considered the best flavored of all pears, but it is still very acceptable - certainly better than you would normally find in most shop-bought pears. It is sweet and juicy, with a hint of violet.

Pears tend to come into blossom quite early in the spring, putting the blossom at risk from late frosts. If this happens Invincible, unusually, will often produce a second set of blossom.
Invincible is also unique in that it comes into bearing at a younger age than most other pear varieties, 2-3 years instead of 4 years or more.
