Oleander: Calypso Latin Name: Nerium Oleander 'Calypso'
The Basics The red-flowered ‘Calypso’ is a large shrub with medium green foliage and greater cold tolerance than most oleanders. Oleander is a tough Mediterranean shrub that thrives where summers are dry and hot. It is a large, evergreen shrub with bushy, rounded to vase-shaped habit. Leathery, linear, lance-shaped leaves line the branches throughout the year and emit white latex when broken. The colorful flowers appear all year around but bloom most heavily from late winter to early summer. They are borne in loose clusters at the ends of the branches and are funnel-shaped at the base with five prominent radial petals that flare at the mouth.
The Needs Amount of Sunlight: Full Sun Amount of Water: Drought Tolerant, Water Regularly Soil Conditions: Well drained Cold Hardiness Zone: 8-11
The Care Oleanders are very drought tolerant but develop a better floral display and overall form if regular water and good growing conditions. Oleander is a popular hedge plant that is often heavily sheared. Shearing is less desirable because it reduces flower production. It is preferable to shape plants selectively with prudent hand pruning. This can be messy due to the white latex the stems emit when cut. Oleander is an excellent plant for difficult areas. It may be planted in large containers, as a specimen shrub, in mixed plantings or for screening.
