Podachaenium eminens (Giant Daisy Tree) - A large fast growing evergreen tropical shrub or small low branched tree to 15 to 25 feet tall by 10 to 20 feet wide with multiple trunks holding large felty gray-green slightly lobed leaves that are 6 to 18 inches across. In spring and early summer plants are covered with inch wide lightly sweet fragrant orange-yellow centered white daisy flowers that are held in many flowered 15 inch wide clusters. Plant in full to part sun and irrigate regularly to occasionally – older plants along the coast are tolerant of dry conditions but look best with at least an occasional watering. Plant in coastal or other near frost free locations, though known to tolerate temperatures down to around 25° F and able to resprout quickly from frost damage. We have also been told by a gardener in San Diego County that Daisy Tree handled the 117° F July 2018 heat wave without damage and was also not damaged by any of the harsh winds that are common at their location. It can be kept denser and smaller by pruning and is useful as a small specimen tree or as a large informal screening planting. Tree Daisy, in the sunflower (Helianthus) tribe, is considered to be one of the largest daisy plants (plants in the Asteraceae) in the world and is native from Sinaloa in Southern Mexico to Costa Rica where is grows in highland forests, including montane cloud forests. The name for the genus comes from the Greek words 'podos' meaning foot and 'achene' (Latinized to 'achaenium') alluding to the base of its single seeded fruit that is called an achene. The specific epithet means "prominent" or "eminent" likely for its showy flowers. Our plants came from seed off of a specimen found growing behind Rudy House on the west campus of the University of California at Santa Barbara, in a location that had not been irrigated for several years. This plant was planted by UCSB Housing & Residential Services Landscape Architect Ric Williams in the 1990s. This tree can also be found growing at the San Diego Botanic Garden (previously Quail Botanic Garden), where a fifty year old specimen was described by Steve Brigham in an article in Pacific Horticulture titled "Trees of San Diego: Daisies… On a Tree?". Plants can also be found at the Fullerton Arboretum and at the Mildred E. Mathias Botanic Garden at UCLA, where if occasionally volunteers seedlings. 

This information about Podachaenium eminens displayed is based on research conducted in our horticultural library and from reliable online resources. We also will relate observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share any cultural information that would aid others in growing it.
