Convolvulus cneorum (Bush Morning Glory) - A fast growing evergreen shrub that forms a rounded 2 to 3 foot tall by 3 to 5 foot wide mound with 1 to 2 inch long silvery-green lance-shaped leaves. White pentagon funnel-shaped flowers, 1 1/2 to 2 inches wide, with yellow centers bloom from pink buds in the late spring through early fall on loose panicles, often in such abundance to nearly cover the plant. It performs best in full sun or part shade with occasional watering and absolutely needs a well-draining soil and not only tolerates, but prefers, alkaline soils. It is hardy to about 15 degrees F. Prune hard in late winter to renew plant when it gets open or too leggy or lightly shear after flowering peaks. Seems to not be terribly long lived in most gardens (likely over irrigated or in heavy soil) but when it is happy it is sensational and its growth rate makes it a very attractive small shrub or filler plant even when short lived. It is native to the rocky coast and islands of southern Europe from Spain east to Croatia and Albania where it is often found growing in cracks in rocks. The name of the genus given by Linnaeus comes from the Latin word 'convolvere' a verb meaning to "roll together" or "to wrap" and is in reference to the vining clambering and covering nature of plants in the genus. The specific epithet comes from 'cneoron' the Greek name for Daphne gnidium so presumably it was thought that this plant resembled this plant. Both this plant and Convolvulus sabatius were winners of the Royal Horticultural Society's Award of Garden Merit in 1993 and we have been growing both since 1985.  The information provided on this page is based on the research we have conducted about this plant in our nursery library, from what we have found about it on reliable online sources, as well as from observations of our nursery crops of this plant as well as of plants growing in the nursery's garden and those in other gardens. We also will incorporate comments received from others and welcome getting feedback from anyone who may have additional information, particularly if this information includes cultural information that would aid others in growing Convolvulus cneorum.
