The Oxalis aka Shamrock is a plant I love to gift to others. It’s a bulb plant and fairly low maintenance; give it a little water and place it next to a window and it’s happy (The plant will stretch to get light – at night it closes up).
I keep the soil moist but not soggy. I may water it 1-2 a week; depending not the time of the year. If you do keep it outside during the warmer months, try to have it in part-shade.
