Oxalis triangularis 'Burgundy Wine (Xalis series)'
Nothing to do with Ireland at all, this tender purple shamrock comes from Brazil.
The handsome burgundy-red foliage and long displays of tubular pale pink flowers, makes for a delightful houseplant.
Oxalis triangularis are highly "photophilic," which means that they open and close not just their blooms, but also their leaves in response to light.
They may also go dormant every couple of years. This is natural so don't discard them. Stop watering and feeding completely. When new shoots emerge start to water again.
They are bulbs so never overwater, allow the soil to dry completely between waterings. Feed with a dilute houseplant fertiliser every two weeks when in growth.
Easy and very long lived.
Well drained, feed
