Soil Moisture: Dry , Moist
Soil pH: Circumneutral (pH 6.8-7.2)
CaCO3 Tolerance: Medium
Soil Description: Rich, well-drained soils.
Conditions Comments: Hophornbeam is appropriate for shady locations but also does well in sun, developing a broader crown there. It is not sensitive to drought but will not tolerate flooding. Resistant to insects (except the gypsy moth), disease, wind, ice, and most stresses of urban living. Notoriously sensitive to salt. Slow-growing.
BenefitUse Wildlife: Some food value to songbirds and small mammals.
Use Other: This is one of the hardest and toughest of the native woods. It was once used for runners on sleighs. (Hosie)
Only occasionally does this tree grow as much as 30 feet high, or produce a trunk a foot thick, nor does it occur abundantly enough to make it commercially profitable. (Peattie)
Conspicuous Flowers: yes
PropagationDescription: Sow immediately after collection or pre-treat and sow in early spring.
Seed Collection: Collect seeds when involucres begin to dry – late summer through October. Wear gloves as the seed clusters can cause itchy fingers. Spread in shallow layers to complete drying. Beat fruit in a sack and separate from the debris by winnowing. Cold stratification is the best means of storing over winter.
Commercially Avail: yes
