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:

DescriptionWhen we say Prima Belarina® 'Spring Sun' primrose (or Primula) will be covered in flowers, we mean it quite literally. It bursts into bloom in early spring, creating a dome of yellow-ruffled flowers that instantly pop in the landscape. Since it thrives in moist soils, we recommend using it in frequently watered containers, moist shady spots, or near water sources. Eclectic and adorable, this old-fashioned flower will not disappoint.
Primroses are an old-fashioned (yet classic) perennial for the garden. Tidy green leaves are smothered with an abundance of ruffled blooms in early spring, while the rest of the landscape is typically dull and dormant. The key to healthy plants: keep your soil moist. With shallow roots, primroses prefer wet or even boggy areas, so don't skimp on watering. They grow well in the shade, but do also enjoy early morning sun to produce the most blooms. Hot climates may find them entering dormancy in the heat of the summer, but don't fret; they'll be back for more each year.DetailsBotanical Name: Primula 'Kerbelsun' Common Name: Primrose Zone: 4-8 Sun Exposure: Part Shade-Shade Height x Width: 5-8" x 10-12" Flower Color: Yellow Foliage Color: Green Season of Interest: Late Winter/Early Spring Bloom time: Spring Features: Rare & unusual, rabbit resistant, heat tolerant, ground covers, deer resistant, container plants, cold tolerant, best for beginners Uses: Container gardening, cottage gardening, edging, ground cover, massing, ornamental, woodland How To GrowSoil: Moist, well-drained soil is best. Primroses cannot handle drought for any sustained period; however, their tight, ground-hugging rosettes of leaves can rot if soil is excessively wet or soggy. Rich, dark soils yield the best results. Light: Partial shade to shade -- Primula will benefit from dappled sun exposure; afternoon shade is imperative in hot summers. Water: Plants will go dormant in hot, dry summer weather unless they are kept well-watered. Mulching will help the soil retain moisture. Spacing: 12 inches Fertilizing: apply a granular garden fertilizer in early spring if desired. Winterizing: A good 2-3" layer of shredded bark is recommended. Check plants in late winter and remove any ice or snow lingering in the rosette to minimize risk of rot. Maintenance & Pruning: These also make excellent container plants - grow in a pot or window box during the spring and then plant in the garden when you turn your containers over to summer annuals.
