Foliage season:

Tall growing hardy Cactus native to cold New Mexico. The pads are armed with 2″ orange thorns that will make you think twice about messing around. To 5′ tall and 4′ wide in 5 years in our climate. Multiplies quickly and large erect pads build up to probably the tallest Opuntia in our climate. In early to mid summer 5″ brilliant yellow flowers are a show stopper. They open just when its hot and sunny enough- closing in any dim conditions. Full, hot, all day sun and very well drained appropriately amended soil. On a slope, double dig the soil to oxygenate it and incorporate hefty amounts of pumice and gravel in the soil. Water regularly through the first summer to establish growth and then none in subsequent years. Extremely cold hardy. Locate away from paths, anywhere you might get too close. Remove deciduous leaves that become ensconced in the pads in autumn. Otherwise it can lead to rot. Long lived. High deer resistance.
