Mathilde Ferrier Oleander, Hardy Double Yellow Oleander
Nerium oleander 'Mathilde Ferrier'
Soft primrose yellow, fragrant double flowers are born in relatively large clusters that open over a long period. Mathilde Ferrier or Hardy Double Yellow Oleander is an old favorite and makes an excellent container specimen as well as being hardy enough to grow throughout zone 8 and warmer regions. In mild winter climates this oleander often acts like large and vigorous growing shrub that can get large enough to be trained into a beautiful small evergreen tree.
USDA Cold Hardiness Zones: 9,10,11, 8B with protection, (8A?)
