Yellow Oleander

Yellow oleander is an evergreen tropical shrub or small tree with narrow, glossy leaves and funnel-shaped yellow to apricot flowers. The [North Carolina Extension Plant Toolbox](https://plants.ces.ncsu.edu/plants/cascabela-thevetia/) describes its cultivation and toxicity, while the [University of Arizona Campus Arboretum](https://apps.cals.arizona.edu/arboretum/taxon.aspx?id=275) documents the flowers, fruit, and landscape form. ## Landscape use In warm climates, this upright plant can serve as a flowering screen, hedge, or patio specimen. In cooler regions it is commonly grown in a container and protected indoors during winter. Mature size varies with climate; tropical specimens can become substantially larger than plants grown in pots or cooler sites. ## Foliage and flowers The leaves are long, narrow, green, and arranged alternately along the stems. Fragrant, funnel-shaped flowers appear in terminal clusters, usually yellow and sometimes apricot-toned. Green fruits turn dark as they mature. ## Siting and soil Grow in full sun or partial shade in fertile soil with good drainage. Water regularly during active growth, allowing the soil to dry somewhat between waterings. Container plants need a free-draining mix and a bright, protected winter location. ## Maintenance Lightly shape after flowering and remove spent flowers if you want to limit fruit formation. All parts are poisonous if eaten, and cut stems release sap that can irritate skin; wear gloves when pruning and keep the plant away from children and pets.
