The 'Kieffer' Pear can be expected to grow in the zones shown on this map.

Attributes:
A long lived tree bearing heavy crops of large yellow fruit. Hardy and vigorous, it bears young and continues dependably for many years. The fruit is good for canning, baking, preserves and honey. Blooms late in the season. Kieffer tolerates hot climates, grows well in most all of the country and is practically immune to blight. While the Kieffer Pear is self-fertile and doesn't require another tree to produce fruit, planting two trees is recommended for a better crop (it will still require insects to pollinate its own flowers).

Our standard Kieffer Pear seedlings are budded onto whole root stock, while our dwarf seedlings are grafted to Quince or Quince A (Malling A).

Chill hours (CU) requirement: 350-400. (Chill hours are the average hours of air temperature between 32 and 45 degrees F in a typical winter season). For best fruit production, calculate the chill unit (CU) for your growing zone to be sure it aligns with the CU requirement of this tree.

Description:
A hybrid between a European and Chinese sand pear with large yellow fruit. The white flesh is crisp, juicy, with a coarse texture. It produces fruit in late September to October. Very hardy and tolerates hot climates. (Self-fertile, plant two trees to ensure pollination) (Zones 4 - 9).

Wildlife Value:
Pear and apple orchards are considered valuable habitats for wildlife.

Height Variations:
The standard grows to 20', and dwarf grows to 12' - 15' in height.

Spread Variations:
Standard spread grows to 20', semi-dwarf grows to 12'-15', and dwarf grows to a 10' spread.

Moisture:
The Kieffer pear prefers moist, well drained soil. It does best when provided with adequate water, but will tolerate both drought and floods.

Leaves:
These simple, glossy green leaves alternate on the twig. They have fine teeth on the margin. Fall color is golden bronze.

White

Bloom Time:
late.

Fruit Description:
Kieffer pears have large, long, golden yellow skin with crimson blush. The flesh is a crisp white, coarse in texture, drier than Orient pear. Harvest late, from mid-September to mid-October. Pick fruit while still hard and store in a cool place--reaches peak flavor when fruit gives slightly to the touch.
