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.
Tree Eucommia ulmoides [Hardy Rubber Tree] The Hardy Rubber Tree is an adaptable, relatively trouble-free plant that makes for an excellent shade tree. Its sap can be harvested for rubber, but this is an expensive and complex process. The specific epithet (ulmoides) refers to the leaf shape of the Elm genus (Ulmus), which is similar to that of Hardy Rubber Tree leaves. It is the only member of this family. Contains about 3% rubber content on a dry weight basis. It…
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 Euonymus planipes [Siberian Spindletree] The Siberian Spindletree is a large shrub (or sometimes small tree) that has showy 4-lobed, crimson fruits appearng in late summer followed by handsome red fall color. Plant can be affected by scale.
Shrub Exochorda racemosa [Common Pearlbush] The Common Pearlbush is lovely in the spring time with its abundance of beautiful, white flowers, but is unfortunately a rather non-descript shrub during the rest of the year. It is a tough plant, able to withstand both heat and drought. The common name refers to the round, pearl-like white flower buds.
Shrub Fouquieria splendens [Ocotillo] Habit of distinctive vertical lines providing a stark texture. Withstand long periods of drought. Leaves fall off when water is scarce, but can reappear within a few days after rain. This cycle of leaf drop and re-growth can reoccur several times a season. Foliage typically last about one month. Water twice a month to retain leaves in the summer. Otherwise, don't water. May not leaf out for a year after transplanting. Protected by Arizona native…
