Oxalis plants usually look good grouped together, so if you’re using a larger container, like an 18-24-inch (45. 72-60. 96 cm) diameter pot, use more than 1 bulb or plant. You can plant up to 10 bulbs in a single container. Oxalis will grow regardless of the bulb’s position.
Oxalis should never sit in standing water.
Plant hardiness zones designate the lowest temperatures in any given region in the world. Zones 6-11 range from −10 °F (−23 °C) to over 40 °F (4 °C). The false or purple shamrock doesn’t require as much sun and thrives in shaded areas. [7] X Research source
