Size

• The mini shamrock plant is more commonly known as "lucky clover." Each stem supports a heart-shaped, three- to four-leaf "clover" and bears a five-petal flower each spring. When fully mature, the average mini shamrock reaches 6 to 8 inches in height -- the ideal size for pots, planters and container gardens.
  
  

Cultivation

• Mini shamrocks are fairly easy to grow and require very little attention once they have taken root. In general, they flourish in cool, moist climates and shady spots -- they do not respond well to direct sunlight, so set them in a sheltered location. Additionally, shamrocks require a dormant period as this gives the roots a chance to rest and regroup. When container-grown plants begin to look a bit run down, stop watering them and wait for the foliage to turn brown, then remove the dead leaves and store the pots in a cool, dry location for eight to 10 weeks. To restart plant growth after dormancy, simply resume watering.
  
  

Selection

• While an abundance of delightful, live mini shamrock plants may be readily available on or around St. Patrick's Day, they may be difficult to come by the rest of the year. Outside of the holiday, mini shamrocks may only be available as bulbs. When purchasing bulbs, be sure to select firm bulbs without blemishes or soft spots. Plant outdoor bulbs in the late fall, before the soil freezes; plant indoor bulbs in 6-inch pots filled with commercial potting soil. Set bulbs at a depth that is approximately two-and-a-half times deeper than the bulb's diameter and keep the soil damp until the plant begins to display clear signs of growth.
  
  

Housekeeping

• Though it may be tempting to remove the fading foliage and flowers from a mini shamrock plant, it is often best to let the plants set seed, particularly when using shamrocks in outdoor areas. This practice encourages self-sowing and helps promote the development of ever larger drifts of greenery.
