Shrub/Tree Euonymus europaeus [Common Spindle Tree] Euonymus europaeus is an adaptable small tree (sometimes large shrub) that can spread and become invasive. The Common Spindle Tree's primary ornamental interest is its attractive and interesting fruits in the fall. Unfortunately, this tree can otherwise be quite unattractive, irregular, and spindley.
Shrub Euonymus fortunei 'Vegetus' [Vegetus Wintercreeper Euonymus] This cultivar has a more shrub-like habit than the species type, but can be moderately effective as a groundcover or wall climber. Also much heavier fruiting than the straight species; the fruiting display can be quite attractive, if fruits are borne in high enough numbers. Very susceptible to Euonymus Scale.

Shrub/Tree Frangula alnus [Glossy Buckthorn] Rhamnus frangula is very weedy (invasive in some areas) and adaptable, and generally has an unattractive, leggy habit. Birds love the fruits and spread the seeds. This species is not recommended for use in the landscape.
Shrub Frangula alnus 'Ron Williams' [sold as Fine Line®] [Fine Line Glossy Buckthorn] Though the name buckthorn is forever a synonym of invasiveness, this cultivar gives the species a round of redemption. Fine Line is a hybrid of the cultivars of R. frangula 'Aspleniifolia' and 'Columnaris', giving its distinct upright habit and the glossy dark green leaves. Though Fine Line will flower and fruit, the seed viability extremely low, removing the invasive threat.

An unattractive ash flower gall (caused by mites) can develop on male flowers and persist into winter. Subject to storm damage, so plant in areas that shelter the tree from strong winds. Emerald Ash Borer is severely affecting all species of this genus. Damage can be prevented…
