The strip of planting along the Skyline Promenade is fantastic for planting sun- and heat-loving plants such as the Bougainvillea, Tecoma capensis (Synonym: Tecomaria capensis), Russelia equisetiformis.
One of my additions include the purple flower, silver leaved Leucophyllum frutescens (Common Name: Barometer Bush, Ash Plant), which I would add to the Discovery Garden slope.
