Quercus gambelii

Bloom Color: Yellow. Main Bloom Time: Early spring, Late spring, Mid spring. Form: Rounded, Spreading or horizontal.

Quercus gambelii is a deciduous Shrub growing to 4.5 m at a slow rate.
It is hardy to zone 4 and is not frost tender. It is in flower in May, and the seeds ripen in October. The species is monoecious and is pollinated by Wind.
Suitable for: medium and heavy soils. Suitable pH: acid, neutral and basic soils. It can grow in semi-shade or no shade. It prefers dry or moist soil. The plant can tolerates strong winds but not maritime exposure.

Landscape Uses:Specimen, Street tree. Prefers a good deep fertile loam which can be on the stiff side. Young plants tolerate reasonable levels of side shade. Tolerates moderate exposure, surviving well but being somewhat stunted. Prefers warmer summers than are usually experienced in Britain, trees often grow poorly in this country and fail to properly ripen their wood resulting in frost damage overwinter. Intolerant of root disturbance, trees should be planted in their permanent positions whilst young. A slow growing shrub that often produces suckers and grows as a thicket, it occasionally makes a small tree. Seed production is cyclical, a year when good crops are produced is followed by several years of light production. The tree flowers on new growth produced in spring, the seed ripening in its first year. Hybridizes freely with other members of the genus. This species is notably resistant to honey fungus. Special Features:
North American native, Inconspicuous flowers or blooms. The plant is heat tolerant in zones 8 through 1. .
At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 to 12 .
For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture information on the habit and root pattern is also useful and given here if available. A clumping plant, forming a colony from shoots away from the crown but with a limited spread . The root pattern is suckering with new plants from underground runners away from the plant .
