Plant Description
Plant Specs

Variety based on fast growth, clean foliage and minimal acorn production. Tree development is totally focused on increased caliper and strong apical dominance along with secondary branches growing at 45 degrees from the trunk. This strong growth rate and lack of acorn production make it an ideal canopy tree in mixed plantings. Colossal oak represents an open pollinated seedling of English Oak as a find in a seed bed at my farm which showed complete immunity to mildew as well as nearly triple the growth rate of nearby seedlings. The parent tree was right next to a pin oak tree in the curb lawn with no oaks around next to a large open field with no natural oaks. This seedling actually seemed to carry some of the pin oak traits including pointy leaves. (However, it is not thought that it is possible that a red oak can cross with a white oak.) As the tree matured the structure did appear to mirror some of the pin oak characteristics with its branching habits.

Colossal oak like Behemoth and Gigant is a selection based solely on growth rate and fast development into a large caliper tree over the course of 40 years. The low acorn production is a bonus in that the trees energy goes into its growth rate.

Plant Specs
Genus & Species	Quercus robur x hybrid
Seed Source	Found in Michigan under cultivation. Parent tree was English Oak.
Hardiness	minus 30 F
Height (ft)	80 ft. with 60 ft. width
Ease of Cultivation	Needs to be grafted onto hybrid rootstock using heat to speed callus. Rooting would be ideal to keep the original root system which also plays a role in fast growh rates. Few acorns are produced but could potentially be developed as a new line of seedling oaks for timber production. Could be a good urban tree with its completely healthy and thick leaves with no narrow crottch angles.
