St Patricks Day Shamrock Planter Arrangement Oxalis Medium

Painted Jar Planters + Shamrocks

Purple and green Oxalis planted in painted jars make a modern arrangement for this St. Patrick’s Day.

St. Patrick’s Day typically reminds folks of leprechauns, green beer, Ireland, and shamrocks: the symbol seen on green-felt fedoras.  But I’m a plant nerd so I think about the shamrock from a botanical point (and I try not to remember those nights drinking green beer).  The symbol of Ireland is the three-leaf old white clover, Trifolium repens, which is common in North America and Europe in grassy areas as well as a pasture crop.  I fondly remember summer days as a child searching for a lucky four-leaf clover lying in park grass.  While many launch a year long fight to get clover out of their lawns, I’m happy to leave it blooming for the bees and give the lawn a rich green colour.

There are a few other three-leaf herbaceous plants that share the Shamrock moniker my favourite being Oxalis.  Native to South America and Africa, this genus of over 500 species are often grown as ornamental plants in home gardens or as houseplants.

Oxalis in my garden in tucked in shady woodland areas where it generally hides from the camera.  To get a few better shots and really enjoy the beauty of the plant, I picked up a few from the garden centre to use in my spring arrangements.

Oxalis regnellii is typically grown in this zone (7-8) as a houseplant due to its vulnerability to frost.  Pale lavender to white flowers bloom regularly on healthy plants given plenty of light but away from direct sunlight.

With Oxalis regnellii ‘Atropurpurea’, the blooms are hardly worth considering when compared to the dark eggplant foliage, often with brighter purple centre leaf margins.

Inspired by the colour palette provided by the two false shamrocks, I created a St. Patty’s day floral arrangement using painted mason jars as planters and as a case for some deep purple tulips.


Painted Mason Jar Tutorial


  • Mason jar(s)
  • Latex house paint
  • Craft paint
  • Foam paint brush
  • Flowers / plants




This is a simple project that I have seen done with spray paint.  I chose to tint some leftover latex trim paint as : a) I had some, b) I wasn’t keen on the fumes from the spray, and c) I wanted more control over the colour.

Simply mix up the colour that you want by added craft paint into the latex pain in a yogurt container. Mix really well then pour a little into your mason jar.  Use the brush to paint the inside evenly and leave to dry.  Apply a second coat if necessary.  One coat is shown here.

To make into a planter, fit a plastic nursery container containing your plant onto the top.  Ensure there is a little lip holding it on the edge so you can remove it when necessary.


To make a vase, insert a thin glass vase into the painted jar.


Choosing interesting shapes and patterned jars will add even more interest to the project.  I like the simplicity of them on my fireplace mantle where they contrast with the painting.


It has also been quite fun to watch the Oxalis “go to sleep” at night, or rather the leaves droop down  as a result of nyctinasty, a plant’s chemical response to the onset of darkness that causes the leaves to tuck in for the night.  It gives these guys a bit of personality which may leave you unconsciously whispering at night as to not disturb them.


Thanks for visiting this weekend’s project.

    What a great idea! I have so many mason jars that could be spruced up….

    Sorry…I just CAN’T “plant” oxalis! After many years of labouriously grubbing it from every single one of my 900+ pot plants and watching in amazement as it regrew and was waving at me from the window every time I looked out at the sea of oxalis flowers I couldn’t in all faith “plant” it! Pretty leaves but some things need to remain sacred and one of those things is my need for a nemsis named oxalis… (one day….ONE DAY!)
