Plant Spacing

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:

bush distance

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:

More Information

Description The only real cure for spring fever is flowers, which Mountainside™ 'Crater Lake' Phlox boasts in heaps and bounds. It blooms up to two weeks earlier than other phloxes! Come spring, this phlox is bursting indigo/purple blooms. The star-shaped flowers are delightfully fragrant, welcoming pollinators back to the garden after a long winter. Unlike creeping phlox, 'Crater Lake' spreads slowly and is easily controlled in small spaces. Plant it as a ground cover in full sun for a blanket of flowers! It pairs perfectly with spring bulbs, like tulips and daffodils. Details Botanical name: Phlox 'Crater Lake'
Patent #: PP32990
Common name: Hybrid phlox, spring phlox, hybrid spring phlox
Zone: 4 - 8
Sun exposure: Sun (6+ Hours)
Height x width: 4-6" x 24-28"
Flower color: Indigo/purple
Foliage color: Green
Bloom season: Late spring-early summer
Bloom time: Midsummer, late spring
Features: Rain gardens, Proven Winners, cold tolerant, best sellers, best for beginners, native
Uses: Alpine and rock, container gardening, edging, ground cover, rock garden, small spaces, border plant, native gardens
  How To Grow Soil: Well-drained soil enriched with organic matter. Plants prefer soil with a slightly acid to neutral pH.
Light: Phlox grow best in full sun (or partial shade in the South)
Water: Low to Average.
Spacing: 24" apart.
Fertilizing: A general-purpose slow-acting granular fertilizer worked into the soil around the plants in the spring is sufficient for phlox for the season.
Winterizing: No special care needed. Leave foliage standing in winter, and clean up spent foliage in spring.
Maintenance & pruning: Cut back stems after flowering by 1/2. This will maintain dense growth and attractive habit for the summer months. This will also encourage some fall rebloom. Cut out any brown stems.

The plants arrived very healthy. They seem to be thriving in their new environment. They haven't bloomed yet, but I'm confident they will once they become established. Very pleased!
