    Maintenance Notes: 

    Self-cleaning, no deadheading necessary. Charmed work fine as short-term houseplants. However, under low-light conditions they are likely to stretch and become lanky. If this happens the plants can be cut back to the top of the soil and they will push out new growth from the roots. It is best to execute this cut back when the plants will be moving to a new, sunnier environment. In most areas they will not be cold tolerant, but they will make an excellent annual groundcover.

    A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

    Am I lucky or what? Dark plum-colored shamrocks the size of your palm. Slender, celery green stalks 12 to 18 inches tall. Clusters of blush pink, lily-shaped flowers. It took Proven Winners' plant breeders' years to make me this gorgeous, not to mention extra healthy and easy to grow. Just remember that sun scorches my shamrocks, so please plant me in part to full shade. You can go berserk and bunch six or more plants together in a sun-challenged area, or do one plant per in smaller pots and group them. Hanging baskets, landscapes, window boxes -- I look good wherever I grow.

    About my roots: I like them moist but not soggy (ugh). Please make sure water drains freely though the pot or garden soil. Like all Proven Winners, I also have a hearty appetite. So feed me once a month with an all-purpose fertilizer. Although I'm an annual except in zones 8 - 11, you can always grow me indoors. All I need is bright, indirect light and low humidity. Since I go semi-dormant in winter, during that time go easy on the water and skip the fertilizer, okay? If anyone asks, I'm the well-behaved clumping Oxalis, not the weedy, spreading type.

    • Really great plant. I bought one a few years ago to decorate the table for St. Patrick's Day, and have since separated it several times and planted it in outdoor pots and shady flower bed areas. It looks very pretty in a pot with a prayer plant and also looks great mixed with green shamrocks (the big ones with pink flowers.) I'm in zone 8 and it overwinters fine with a little protection during the infrequent freezes. Even if it gets frost bitten, the tubers survive and it comes back in the spring.

    • I've grown this plant outdoors with great success. However, I'm having a hard time with it indoors. Strange.

    • I like the color choices this plant have. This shamrock really makes for a great conversation piece. I live in Harris county TX, in zone 9. It does well in most shade for me.

    • I have never used this plant in my pots before. It is such a beautiful addition to my garden. The color is brilliant and has grown far beyond my expectation.
