Lovely Flowering Ligularia Plants
Ligularia is a small genus of perennial flowering plants native to the bogs and marshlands of Europe, Africa, and parts of Asia. Growing three to six feet tall and three feet wide, the large purple tinged foliage topped with bright yellow flowers of ligularia have a dramatic effect in a part-shade or shade garden. The name is derived from the Latin “ligula,” which means little tongue, and refers to the shape of the florets on the flower spire. This genus of plants is hardy in USDA plant hardiness zones 4 to 8. They thrive in areas along rivers or ponds in partial shade. Ragwort flower is especially adaptive to a range of pH levels but requires a nutrient-rich soil with plenty of compost or leaf litter worked into it. Prior to planting mix in a handful of bone meal and some peat moss to increase moisture retention. Ligularia planting instructions state that you must plant the crown at least ½ inch below the soil level. Apply mulch around the plants to help conserve moisture. Don’t worry if the foliage wilts after planting or in the summer heat. The ornamental leaves are sensitive to excess heat or disturbance. After temperatures cool down in the evening, the foliage will perk up and look fresh again.
This is a carefree plant as long as site selection meets its needs. The leaves can also become scorched when the bright midday sun burns them. Water the plants deeply every week or as needed in warm weather to keep soil moist. Cut off any dead or damaged leaves to the base. When the plant goes dormant in winter, place 3 inches of mulch over the crown. Pull it away from the base of the plant in early spring when the ragwort flowers begin to sprout.
