Ozothamnus leptophyllus 'Silver Cape' PP19,992 (Silver Shore Cottonwood) - A compact upright shrub to 3 feet tall and wide with tiny leaves attractively covered in silver-white fine hairs (tomentum) and spiraled tightly along the stem. The tiny flowers are not significant but emerge from pinkish white heads at branch tips spring through summer. Plant in full sun with occasional to infrequent irrigation. Hardy to 20F. This is a brand new plant for 2013 so there is yet much to learn about it but it should prove to be a tough attractive shrub for the garden that is tolerant of dry poor soils and even seaside conditions - looks a bit like an upright growing Plecostachys which should be good to use with contrasting colored plants. This plant is a selection made by Lindsey Hatch of hybrids that resulted in a cross between several Ozothamnus leptophyllus that took place in cultivated area of Pukekohe, New Zealand in 2002. The selection was made over other selections and the species for reasons of its compact growth with more silvery and shorter leaves that are held in a spiral arrangement with very short internode lengths. This plant received US plant patent PP19,992 in May 2009, unfortunately using the erroneous name Ozothamnus leptophylla. Ozothamnus leptophyllus is the current name for this native New Zealand species that was long called Cassinia leptophylla but most recently, reclassified as a Ozothamnus and by some combined with an Australian species as Ozothamnus lepidophyllus (Ilse Breitwieser & Josephine M. Ward (1997): Transfer of Cassinia leptophylla (Compositae) to Ozothamnus , New Zealand Journal of Botany, 35:1, 125-128). It is called Silver Cottonwood or by the Maori name Tauhinu and in New Zealand is a common shrub in coastal areas, including on sand dunes on both the North and South Island as well as Stewart Island. This plant is being marketed in the US by Ball Horticultural. Our plants and the accompanying image from Ball Horticulture. Really interesting plant when young and fresh botu it holds old dried up foliage, making it look a bit messy - we discontinued growing it in 2014.  This description is based on our research and observations made of this plant as it grows in our nursery, in the nursery garden and in other gardens that we have visited. We will also incorporate comments received from others and always appreciate getting feedback of any kind from those who have some additional information about this plant, in particular if this information is contrary to what we have written or if they have additional cultural tips that would aid others in growing Ozothamnus 'Silver Cape PP19,992.
