Gocanzam Golden Candle™ Goldenrain Tree

Golden Candle™ is a narrow, columnar form of goldenrain tree, identified as Koelreuteria paniculata ‘Gocanzam’. It carries upright clusters of golden-yellow flowers above deep green foliage, followed by lantern-shaped seed capsules. The [Sooner Plant Farm listing](https://soonerplantfarm.com/plant/golden-raintree-golden-candle) describes the selection’s slim form, golden flowers from late spring into early summer, and fall foliage color. ## Size and placement The cultivar listing gives a mature range of 25–35 feet tall and 4–6 feet wide, with hardiness zones 4–9. A [University of Illinois Extension species profile](https://web.extension.illinois.edu/hortanswers/plantdetail.cfm?PlantID=219&PlantTypeID=7) lists the same height range and zones 5–8 for goldenrain tree generally. Since hardiness guidance differs, use local winter exposure and drainage to choose a site. The upright shape suits a narrow planting area or a specimen position where the flowers and papery capsules can be seen. ## Growing conditions Plant in full sun and moist, well-drained soil. The species tolerates dry sites and alkaline soil after establishment, but regular watering helps a young tree develop. Goldenrain trees are deciduous; the University of Illinois profile describes mid-summer yellow flowers and inflated capsules that change from green to apricot and brown. ## Maintenance Keep the young trunk and main leader clear of competing branches if a strong upright form is desired. Once established, water during prolonged dry spells and prune sparingly to remove damaged or crossing branches. Allow room for the listed mature height and spread.
