Description Echinopsis oxygona 'Easter Lily Cactus' Care Guide FAQ/Common Issues Echinopsis oxygona, also called Easter Lily Cactus, is a globular to columnar cactus in the Cactaceae family native to South America, where it grows across Argentina, Uruguay, and southern Brazil. It grows indoors and outdoors with minimal fuss. The plant forms a rounded, ribbed body covered in symmetrical rows of spines, creating a sea urchin-like silhouette. It grows upright in a clumping habit, producing offsets freely around its base that spread into an impressive cluster over time. The green skin, defined ribs, and dense spine clusters create a satisfying form among drought tolerant cacti. Echinopsis oxygona earns its common name with trumpet-shaped blooms that emerge in spring and early summer, ranging from soft pink to vivid magenta with a luminous white throat. These fragrant flowers are night blooming, opening in the evening and releasing a sweet scent. A single plant produces multiple blooms in one season, and a well-established clump puts on a significant floral display. Move it outside in summer for stronger growth and better blooms. You can leave it up to ten days without water. A cool night temperature drop in autumn to 50–55°F triggers flower bud formation. Keep it on a high shelf away from small children due to sharp spines, though it is cat friendly and dog friendly. You can propagate it easily by removing the offsets that cluster around the base and potting them in dry cactus mix. Echinopsis oxygona 'Easter Lily Cactus' grows well in bright indirect light, partial sun, or full sun near a south or east-facing window. Water it thoroughly every 10 to 14 days in summer and reduce to once a month or less in winter when the plant is resting. Echinopsis oxygona does best in well-draining cactus and succulent mix blended with extra perlite or coarse sand. It prefers temperatures between 50 and 90°F and tolerates brief dips near 25°F when kept dry. Echinopsis oxygona is a moderate grower that benefits from balanced low-nitrogen cactus fertilizer applied once monthly during the active growing season. It is hardy in USDA zones 8b through 11, tolerating short frost events down to around 25°F when the soil is dry. It grows outdoors in California, Arizona, Nevada, Texas, Florida, Hawaii, Louisiana, Mississippi, Alabama, Georgia, South Carolina, and coastal Oregon. It also succeeds outdoors in parts of New Mexico, Arkansas, North Carolina, and Virginia with good drainage and frost protection during cold snaps. Q: How often should I water Echinopsis oxygona 'Easter Lily Cactus'? A: Every 10 to 14 days during spring and summer while the soil dries between waterings. Cut watering back to once a month or less in winter. Q: Will the plant bloom indoors? A: Echinopsis oxygona 'Easter Lily Cactus' blooms indoors if you provide a cool night temperature drop in autumn to 50–55°F, which signals the plant to set flower buds. Moving it outside for summer also encourages stronger blooming. Q: Is Echinopsis oxygona safe for cats and dogs? A: The plant is non-toxic and pet friendly, but the spines can cause physical irritation if brushed against, so place it out of reach of curious pets. Q: How large does the plant grow? A: Echinopsis oxygona typically reaches 6 to 12 inches tall and wide, but the clumping habit means a mature plant spreads considerably wider as it produces offsets over the years. Q: Can Easter Lily Cactus be propagated at home? A: Simply remove the offsets that cluster around the base, let the cut end callous for a day or two, then pot them up in dry cactus mix where they root quickly. Q: What window placement works best indoors? A: Place Easter Lily Cactus near a south or east-facing window for bright indirect light or partial sun. Full sun exposure is also suitable, though leaf color may shift slightly in intense afternoon light.
