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.

Not well plants

These didn’t work out for me and once planted, look about exactly the same as they came. Four weeks and zero growth, no perkiness in the foliage, just meh. I moved out of full sun and keep in partial right now until they die or maybe live.

A survivor

First year I was certain wouldn't survive 6b winter. Just a stem hanging on each plant. Next spring little bushy beautiful striking color plants popped up! Ordering more because the color is magnificent!
