Lily of the valley, or convallaria, is native to moist woodland areas in Europe and has taken well to cooler parts of the U.S. This low growing, spreading plant establishes well in shady sites under trees and shrubs. Convallaria’s ability to form a neat, flowering mat, covering bare ground and perfuming the air in spring, has earn it a place in many hearts, and gardens.
Lily of the valley plants prefer at least partial shade and are happy with a range of light from dabbled sunlight to moderately shady to the shade that’s found on the north side of buildings. These hardy perennials gently spread with underground runners to fill in and crowd out weeds. Maturing to just 8” tall, they always look neat and trim, without having to be, well, trimmed.
Light to moderate feeders, lily of the valley grow well in average, well-drained soil and doesn’t require rich, perfect loam. Compost, dug in when planting or added as a top dressing later, provides a welcome supply of nutrients.
Plant outdoors when frost danger has past. Lily of the valley plants are super winter hardy perennials that can take severe freezes without ill effects once they are established. Their first spring however, plant after frosts are past.
Your lily of the valley ships bareroot, in a dormant state. Dormancy means the plant is not in actively growing; it’s been held in a cool, dark setting similar to winter garden conditions and is “sleeping”. The bareroot term means that the soil has been washed from the roots; there is no risk of introducing any soil-borne diseases into your landscape. Also the plants are lighter and cleaner to ship. When you plant your lily of the valley, adding light and moisture, they’ll wake up. Roots start growing in a few days and top growth is usually visible in 1-3 weeks.
Dig up your planting area to a depth of about 6”. Add a few shovels full of compost and mix it in. Smooth the soil. Tease your lily of the valley plants apart and scoop a handful of soil aside. Place the pip, the slender rooted plant, in the shallow hole and fan out the roots so they’ll be able to absorb moisture and nutrients from as wide an area as possible. Settle the soil around the pip so the roots are covered and the pointed tip is above the soil. Refill around plant with soil, tap down to eliminate any big air pockets and water well.
While you are planting, keep the rest of the pips from drying out. Roll them in a moist dishtowel or place in a bucket of water for an hour or two.
Space your pips about 6” apart. The roots will spread underground and new shoots will grow, filling in the area between the plants added this spring.
Keep the soil fairly moist w for the first few weeks, while your pips are settling in and developing a strong root network. After that, lily of the valley require about 1“of water a week, from rain or irrigation or a blend of the two.
Lily of the valley don’t need any special trimming or fertilizing in the autumn. Water if there’s a dry spell. Other than that, they’re easy.
