Plant spacing is based on the ultimate width of the plants. This figure is normally given as a range; for example, 3-5’. If you live in a cold climate and/or want plants to fill in more quickly, plan to space at the shorter end of the range. If you live in a warm climate, are on a limited budget, or are willing to wait longer for plants to touch, use the higher end of the range. Using the larger number is recommended when calculating distance from a building or structure. There’s really no such thing as "maximum spacing": if you don’t want your plants to touch, you can space them as far apart as you’d like. All plant spacing is calculated on center, or in other words, the centers of the plants are spaced one half of their eventual width apart:
Unless you are planting in a straight line, as you might for hedges or edging, space your plants in a staggered or zig-zag pattern for a more interesting and naturalistic look:

Description'Twinkle Toes' lungwort will have you giddy with early blooming flowers, eclectic foliage, and an easy-to-grow nature. In late spring, periwinkle blue flowers dance above the foliage, and after they fade, their silver-speckled leaves take center stage. The foliage always seems to shimmer, even in full shade. Use it as a ground cover, container filler, or a border for a long-lasting display.
Pulmonaria, or lungworts, are woodland perennials with green and silver-speckled foliage. They thrive in full or partial shade, serving as an intriguing groundcover with a tidy and low habit. As a cousin of Brunnera (or bugloss), lungworts complement other early spring bloomers with colorful flowers. They are deer and rabbit resistant, pollinator-friendly, and low maintenance for beginners. Plant this perennial in a shady spot alongside hostas, hellebores, or astilbe for a dynamic shade landscape. Keep them well-watered, and they'll reward you with shimmering foliage from spring to fall.DetailsBotanical name: Pulmonaria 'Twinkle Toes' Patent #: USPP 30,258 Common name: Lungwort, Bethlehem sage Zone: 3 - 9 Sun exposure: Shade (< 4 hours sun) to part-sun (4-6 hours sun) Height x width: 12-14" x 16-18" Flower color: Blue with some purple Foliage color: Green with silver spots Season of interest: Spring through fall Bloom time: Early spring Features: Rabbit & deer resistant, proven winners, low flammability, cold tolerant Uses: Accent, container gardening, cottage gardening, massing, ornamental, specimen, woodland How To GrowSoil: Prefers cool, organically rich soils that are kept consistently moist. Light: Shade (< 4 hours sun) to part-sun (4-6 hours sun). Foliage may scorch if grown in too much sun. Although plants tolerate light morning sun, they need afternoon shade. Water: Average. Don't allow the soils to dry out. Spacing: 18 - 24 inches Fertilizing: Fertilizing is not required unless the soil is lacking nutrients. If needed, spread compost manure as soon as flowering is complete. Winterizing: Allow the plant to die back in the winter and trim the dead foliage in spring. Maintenance & pruning: Try to keep these plants in an open, airy position with no night time or overhead watering to minimize mildew risk. Remove flower stems immediately after bloom. Plants can be cut back hard immediately after blooming to rejuvenate the leaves, which will then remain attractive all season. Foliage is evergreen in mild climates.
