Need a mighty native tree that you are sure no one else in the neighborhood has? Look into the Blackjack Oak Tree (Quercus marilandica) and enjoy its bristly, lobed leaves that sport shiny surfaces with rusty-yellow hairy undersides. The two-tone effect looks fantastic waving in the wind!
The rosy new growth is highly anticipated each spring as the long catkins of greenish-yellow flowers appear and attract loads of butterflies and bees looking for some nectar. The strong limbs and leafy shelter provide birds protection while roosting during the dormant season.
Featuring nearly black bark that's rough, blocky, and resembles alligator skin, Blackjack Oaks form unique rounded lobed leaves that flare out wider at the ends with narrow bases. Accented by densely-growing contorted limbs, these are ideal firescaping trees because of their thick bark that protects them.
Fall color arrives and graces your glossy foliage with rusty reddish-purple hues. Then persisting all winter for rustling sounds and winter interest! Blackjack Oak acorns ripen between September to October, and your wildlife will enjoy the yellow-brown nuts sporting turban-shaped acorn caps!
Planting and Application:
Majestic shade and street trees, their form is informal and sometimes appear scrubby when young. Give them room to develop their attractive, symmetrical form. These ornamental trees act as wonderful screens and borders, hedgerows, and shelterbelts for wildlife to nest, shelter, and feed in!
Highly adaptable, the tree itself is a boon to insect-eaters and their hungry chicks! Oaks are Host Plants for hundreds of butterfly and moth caterpillars! Squirrels, chipmunks, and waterfowl enjoy these acorns.
The Blackjack Oaks' impressive presence in your landscape is outdone only by the sheer number of birds and beneficial insects that flock to this tree! Growing 20-40 feet in height and width, you'll love the cooling and money-saving shade these trees provide you and your home is well worth the wait!
- Pinkish New Growth & Two-Tone Glossy Foliage
- Pollinator & Wildlife Trees
- Firescaping & Xeric Native Trees
- Great Fall Foliage & Ornamental Acorns
- Four-Seasons of Interest, Shade & Street Trees
#ProPlantTips for Care:
Oak Trees grow best in full sun and are often found growing in the poorest soils. Low moisture needs once established, in nature, these native trees thrive in sandy soils and hardpans and tolerate acidic soil conditions. Add Nature Hills Root Booster for lifelong root support. Give new trees regular moisture and a good staking system to maintain straight trunks. Slow-growing, hardy, and adaptable, these long-lived specimens can be found throughout USDA zones 6 through 9 and appreciate pruning during the winter or early spring before new growth emerges.
- Full Sun Trees
- Poor to Average, Well-Drained Soils on the Acidic Side
- Average to Low Moisture Once Established
- Drought Tolerant & Responds to Mulching Well
- Prune When Dormant
