The oxalis family is broad and diverse, including several rampantly invasive types that have earned oxalis a bad reputation as “garden thugs.” Many oxalis species are completely obedient and make lovely additions to your house and yard. Two types, oxalis triangularis and regnelli, are suitable for growing inside as long-lived houseplants and are hardy in all American climes. Both can survive outside in zones 6 to 11, but they adapt easily to indoor environments and flourish well there all year. Let’s take a closer look at oxalis triangularis with its creative and interesting purple foliage.
Oxalis Triangularis Origins
“Purple shamrocks” are another name for oxalis triangularis. The origins of the plant can be attributed to St. Patrick, who utilized a related plant and its three leaves to teach the Irish about the Holy Trinity. Oxalis triangularis are not indigenous to Ireland; rather, they are Brazilian in origin.
Special Traits
Highly prized oxalis triangularis “They are photophilic, which means that light causes them to open and close not just their blooms but also their leaves.

Basic Care
The bulbs of the oxalis triangularis resemble young, little pinecones. Plant your bulbs closely together in a container for indoor use to quickly get a full appearance. It’s fine to simply stab the bulbs into the soil from any angle. Until new growth starts to sprout, water the plant minimally just once every two weeks. Your fresh purple shamrocks will start to bloom and fill in to become lush and full about 6 weeks after you plant them. Weekly watering has to be minimal. The plant will return to dormancy if it receives too much water.
Keep your oxalis triangularis in a bright area indoors. Your other indoor plants will appear to be glowing with vitality thanks to the deep purple foliage’s ability to highlight the vivid green of other plants.
Please be aware that oxalis triangularis can periodically fall dormant and appear to be dead as a whole. This often occurs during the summer when the plant is indoors once every two to seven years, thus it appears to be a significant issue rather than a recurrent occurrence. No need to throw away your cherished triangularis! Just stop watering and let the soil to completely dry up. Place the plant out to the side so that it is visible but out of the way.

Can you plant Oxalis triangularis outside?
This houseplant is what I like to refer to as a “indoor/outdoor” plant since, depending on the season, it uses both of these locations. During the winter, it lives in my kitchen, but in the spring, it spends its time on my balcony until the end of the growing season. It is the oxalis triangularis, sometimes called the purple shamrock, false shamrock, or love plant.
This plant caught my attention when I first saw it in a lovely display outside Liberty (see above photo). A few weeks later, I couldn’t believe my good fortune when I spotted a tiny cluster of purple leaves growing among some herbs in a relative’s garden. I drove home with it in a planter after digging it up (I did inquire beforehand), where it afterwards resided on my balcony. When winter arrived, it entirely withered away and looked like a pot of soil. I brought it inside and put it beneath my kitchen table till the weather warmed up since I was a little worried. For a time, it still appeared like though I was looking after a pot of dirt, but then the plant suddenly appeared! This year, it quadrupled in size and grew extremely well. Lots of long-lasting white flowers with pink undertones are flowering in amongst the lovely, delicate leaves. After its subsequent dormant time, I intend to divide the plant into smaller pots so that it can live more easily indoors because it is pretty enormous!
CARE ADVICE:
This one is really simple to maintain. Every 7 to 10 days, I give the love plant a baby bio feed, and every three to four days, I softly water it. If the leaves appear to “shut” in the evenings, don’t panic—they will reopen in the morning!
This plant may thrive both indoors and outdoors in the spring and summer, preferring a shaded location over direct sunlight.
Note on its dormant stage
When the leaves stop expanding during the day, you’ll know this is coming. At this point, you can prune the plant back if the leaves start to wither. At this point, avoid watering it because doing so will cause the roots to rot. The plant can be fed and watered as usual as you see active growth.

How to Care for oxalis
The majority of oxalis do best in containers, where they will flower profusely and keep their lovely color throughout the summer and fall. They prefer a cool, sunny or somewhat shaded outdoor area. Hardy forest species of oxalis require fertile, humus-rich soil that is wet and partially or completely shaded. Bring the plants inside so you may enjoy them all winter long. Some plants will go dormant for a few weeks in the winter in order to reduce watering until the spring when the light levels start to increase.

Plants respond to the beginning of night with a type of repetitive circadian nastic movement known as noctinasty. Through sensors, the plant detects the type and quality of light and responds by sending a signal to the pulvini, which are joints bulging with cells near the base of the leaflets. The subsequent release of carbohydrates and potassium ions from the pulvini results in the distinctive drooping of the leaflets.
