Shrub InvasiveThis plant is considered invasive Elaeagnus umbellata 'Cardinal' [Cardinal Autumn Olive] Elaeagnus umbellata 'Cardinal' was originally introduced by the Soil Conservation Service and is not recommended for the home landscape. Widely adaptable and invasive plant in the Midwest. Like other members of the family, fixes atmospheric nitrogen. Spread by birds and through rooting suckers. Especially tolerant of extreme cold and drought, as well as extreme heat, unlike the related Elaeagnus angustifolia (Russian Olive).
Shrub Eleutherococcus sieboldianus [Fiveleaf Aralia] Tolerates a wide range of soil and environmental conditions, including dry city conditions and shade. Little seasonal interest other than foliage, but extremely durable shrub. Prickles on stems can make pruning difficult. In poor sites, renewal pruning can improve form. In rich organic soils, renewal pruning can lead to rank growth. Usually dioecious.
Shrub Eleutherococcus sieboldianus 'Variegatus' [Variegated Aralia] This cultivar has attractive, creamy variegated foliage and is more compact than the straight species. Tolerates a wide range of soil and environmental conditions, including dry city conditions and shade. Prickles on stems can make pruning difficult. In poor sites, renewal pruning can improve form. In rich organic soils, renewal pruning can lead to rank growth. Usually dioecious.
Tree Eucalyptus papuana [Ghost Gum] Gained its common name from its beautiful, smooth, white bark. Drought tolerant, low water use once established. Adapted well to urban conditions. The leaves have a high phenolic acid content and make it difficult to grow other plants beneath the Ghost Gum. The eucalyptus beetle poses greatest threat, with oval-shaped holes being one of the signs of infestation.
Shrub InvasiveThis plant is considered invasive Euonymus alatus [Winged Euonymus] Widely tolerant of most soil and microclimatic conditions, but develops good fall foliage color only when exposed to considerable direct sun. Tolerates heavy pruning. Can be troubled by scale insects, although not so frequently as the evergreen euonymus. Fruits are toxic. Avoid very dry or wet sites. Can be invasive, seeding into woodlots.
Shrub InvasiveThis plant is considered invasive Euonymus alatus 'Compactus' [Dwarf Winged Euonymus] The dense and lower-growing 'Compactus' is one of the most common Winged Euonymus cultivars. Widely tolerant of most soil and microclimatic conditions, but develops good fall foliage color only when exposed to considerable direct sun. Tolerates heavy pruning. Can be troubled by scale insects, although not so frequently as the evergreen euonymus. Fruits are toxic. Avoid very dry or wet sites. Can be invasive, seeding into woodlots.
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.
Liana (Climbing Vine) InvasiveThis plant is considered invasive Euonymus fortunei [Wintercreeper Euonymus] Best in soil that is reasonably moist, either in full sun or shade, but not heavy wet soils. Can be used as a wall climber (possibly climbing up to 70') or groundcover. Subject to Euonymus Scale that can kill some plants, especially 'Vegetus' and 'Coloratus'. Euonymus fortunei is a vigorous vine that invades forest openings and margins. It grows across the ground, displacing herbaceous plants and seedlings and climbs trees high into the tree canopy…
Liana (Climbing Vine) InvasiveThis plant is considered invasive Euonymus fortunei 'Coloratus' [Coloratus Wintercreeper Euonymus] Can tolerate full sun to full shade. Best in soil that is reasonably moist, but not heavy or wet. Can be used as a wall climber, but is best as a groundcover. This vigorous form turns purplish-plum during the winter months. Can be subject to Euonymus Scale. Euonymus fortunei is a vigorous vine that invades forest openings and margins. It grows across the ground, displacing herbaceous plants and seedlings and climbs trees high into the…
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.
