Buckeye, Red (Aesculus pavia) 

A great ornamental: beautuful red flowers (pictured above) in spring...palmately compound leaves aren't bothered by Japanese beetles and provide an interesting textural effect...easy to grow in sun or complete shade...a red buckeye planted in heavy shade has averaged 18 inches of annual growth with regular watering...great patio or accent tree that stays small, reaching only 10-15 feet tall.  2' tall $38; 4-5' tall $68

 

Crabtree: White Flowering

Red Jewel grows to only 15 feet high and has persistent bright red fruit that is smaller than most crabs, making it less messy...attractive bright green leaves. 4-5' tall $48 

 

Crabtree: Pink Flowering

(Malus x 'Purple Prince')

'Purple Prince' is named for its small purple fruits that persist during winter months and provide food for birds...rosy red spring flowers and leaves that emerge bronze and mature to a nice green (rather than the drab purple color that many red and pink flowering crabs produce)...rounded habit with upright, spreading branches eventually reaching 20 feet high and wide...good to excellent resistance to the various leaf maladies that impact crabs during wet, cloudy weather...known to be fast growing but not week-wooded.

Dogwood, Pagoda (Cornus alternifolia) Native

This native dogwood (see pics above) boasts an attractively tiered, horizontal branching pattern with fragrant white flowers that bloom from late May to early June…one of the most interesting features of pagodas are their fruits, which are dark blue and positioned at the top of a reddish purple stalk….a small tree that reaches only 15-20 feet tall at a rate of about 12 inches annually…like most dogwoods, pagodas prefer life in the shade: best landscape conditions include a few hours of morning sun and afternoon shade. 1-2' tall $18 to $38
