Carya illinoinensis 'Stuart'

Common Name(s):

Phonetic Spelling
KAIR-yuh il-ih-noy-NEN-sis
Description

The 'Stuart' pecan is a cultivar of the native pecan tree in the walnut family (Juglandaceae) and is typically grown in the southeastern United States. It originated from a seed planted in 1874 by J.R. Lassabe in Pascagoula, Mississippi. The property was purchased by Capt. E. Castanera and the cultivar was originally known as 'Castanera'. It was later propagated by Col. Stuart and offered commercially in 1892 as 'Stuart' (perhaps because colonels outrank captains).

This vigorous tree grows 80 to 100 feet tall and 40 to 75 feet wide.. It does best in full sun in well-drained moist loamy soils with a pH of 6.0 to 6.5. It needs less pruning than other varieties. Be sure to irrigate during dry spells. It has medium resistance to scab.

The tree bears fruits with medium-thick shells in 8 to 10 years and fruits are typically harvested mid-October. The kernel is plump and firm-textured with a rich flavor. It is a type 2 pecan and needs a type-1 for pollination. It is compatible with 'Amling', 'Cape Fear', 'Creek', 'Desirable' and 'Mandan'.  Learn more about selection, planting, and care of pecan trees.  For optimum pollination, NC State Extension recommends planting at least three cultivars with at least one of each pollination type for best cross-pollination. 

Due to its size, this is a tree most appropriate for a large property. It makes a good shade tree in a naturalized, woodland, or recreational area and as part of a children’s, edible, or pollinator garden.

Quick ID Hints:

  • Leaves are alternate, pinnately compound
  • Leaflets are falcate, crenate

Insect, Diseases, and Other Plant Problems: This tree is susceptible to wind damage. Aphids, pecan weevils, stink bugs, twig girdlers, and fall webworms can cause some issues. Medium resistance to scab.. Late frosts can reduce nut production. Messy
