Old fashioned silverberry, Elaeagnus pungens, has always been useful for large informal hedges and barriers in difficult locations. It may not be as refined or as bright green as other plants that are more commonly used for formal hedges; but it is more adaptable to harsh exposure, since it has no problem with heat and reflected glare.

If necessary, silverberry can be shorn like privets, but is at its best with only occasional selective pruning to keep it within bounds. Without pruning, it can grow to more than ten feet high and nearly as wide. Despite its slower growth at maturity, it grows faster and fills out quite efficiently while young.

All parts of silverberry are covered with slightly raspy and silvery or ‘rusty’ tomentum (fuzz – although it is not exactly ‘fuzzy’). The one to two and a half inch long leaves often have undulate margins. The less than abundant, half inch long brownish berries taste better than they look. Somewhat spiny vigorous stems efficiently deter intrusion. Trespassers that might get through them once will not try again. 

Modern cultivars (cultivated varieties) are neither as rugged as the straight species, nor as large, but have more colorful foliage. Leaves of ‘Variegata’, which is shown in the illustration, have lemony yellow or nearly white margins. ‘Marginata’ has brighter white leaf margins. ‘Maculata’ leaves are instead equipped with bright green margins around bright yellow centers. ‘Fruitlandii’ has larger silvery leaves.
