Planting & Care

Where to Plant

Sunlight: Plant this perennial where it receives at least 6 hours of direct sunlight daily for the highest bloom count and strongest stems. It can tolerate light afternoon shade, particularly in hotter climates, though full sun helps keep foliage dry and healthy.
Soil: Ensure the planting site has well-draining soil rich in organic matter to prevent root rot. If dealing with heavy clay, amend the area with compost to improve drainage, or use peat moss in sandy soils to help hold moisture near the roots.

Watering Requirements

Water deeply and regularly during the first growing season to help the roots establish, keeping the soil consistently moist but not soggy. Once established, supplemental watering during dry spells prevents the plant from wilting and reduces susceptibility to powdery mildew.

Pruning Tips

Cut the stems back to the ground in early spring before fresh green growth begins to emerge. You can also snip off spent flower heads right after the initial bloom fades to encourage a second flush of color later in the season.

Fertilizer Needs

Feed your Phlox with a balanced, slow-release granular fertilizer in early spring when you see new shoots. Avoid heavy nitrogen applications later in the season, as this pushes soft leafy growth rather than flowers and can make the plant vulnerable to winter damage.

Understanding Our Container Sizes

At Nature Hills, our plants are sold in industry-standard nursery containers. You will notice we use the word "container" rather than "gallon." Container numbers follow a nursery trade size standard, not liquid volume. The number tells you the plant's size category and general maturity level. A larger container means a more established plant with a stronger root system.

Container Sizes

Quart

Plant age: 6 months to 1 year
Best for: Ground covers, perennials, ornamental grasses
What to expect: Our smallest and most affordable size. Well-suited for planting in multiples across a large area. Allow 1 to 2 seasons for full establishment.

#1 Container

Plant age: 1 to 2 years
Best for: Shrubs, perennials, smaller trees
What to expect: About the size of a large coffee can. A well-developed root system in a manageable size. Good value choice when you have time to let the plant grow into the space over a season or two.

#2 Container

Plant age: 2 to 3 years
Best for: Shrubs and trees where you want faster establishment
What to expect: A noticeable step up from a #1 in both plant size and root development. Good choice when you want visible presence without going to a larger size.

#3 Container

Plant age: 3 to 4 years
Best for: Most plants, most situations — flowering trees, shade trees, evergreen shrubs
What to expect: Our most popular size. Strong, developed root system. Plants in a #3 container make an immediate visual impact from day one. If you want a head start rather than waiting seasons for a plant to fill in, this is typically the right choice.

#5 Container and Larger

Plant age: 4 to 5+ years
Best for: Specimen plants, privacy screens, maximum instant impact
What to expect: Large, mature plants ready to make an immediate statement in your landscape. We also carry #7 and larger sizes for select varieties.

Why "Container" and Not "Gallon"?

Nursery container sizes follow an industry trade standard established for the nursery and horticulture industry. The number is a size designation, not a measurement of liquid volume. Actual soil volume varies by plant type, root mass, and growing medium. Using "container" is the accurate industry term. When you see #1, #2, or #3, think of it as the plant's size tier, not a gallon measurement.

Root Pouch Containers

Some Nature Hills plants arrive in a Root Pouch, a breathable fabric container made from 100% recycled materials. Root Pouches encourage denser root development through air pruning, which discourages root circling and promotes a stronger, more fibrous root ball at the time of planting.

There are two types. Knowing which one you have changes how you plant:

Degradable (brown or tan fabric): Plant the entire pouch directly in the ground. The fabric breaks down naturally in the soil over time.
Non-degradable (black or gray fabric): Remove the pouch before planting. Cut the bottom open with scissors, then peel the sides away. The fibrous root ball will hold its shape.

Not sure which type you have? Check the tag on your plant or contact us and we will confirm.

#1 Container	1 to 2 yrs	Shrubs, perennials, small trees. Value choice for patient gardeners.

#3 Container	3 to 4 yrs	Most plants. Immediate visual impact. Our most popular size.

Frequently Asked Questions

Is Larissa Phlox deer-resistant or do deer eat it?

Larissa Phlox is not deer-resistant and deer will browse on it, especially the tender new growth and flower buds. This 2-3 foot tall perennial is particularly vulnerable during its mid-summer bloom period. Consider using deer repellent sprays or plant it behind more deer-resistant perennials for protection.

When is the best time to plant Larissa Phlox in my garden?

Plant Larissa Phlox in spring after the last frost or in early fall, 6-8 weeks before hard freeze. This gives the roots time to establish before summer blooming or winter dormancy. Space plants 2-3 feet apart and shop at Nature Hills for healthy, nursery-grown stock.

How hardy is Larissa Phlox in cold winters or hot summers?

Larissa Phlox is a hardy perennial that tolerates both cold winters and hot summers well in its suitable growing zones. As a native North American plant, it's naturally adapted to temperature fluctuations. Plant in well-draining soil and provide afternoon shade in extremely hot climates for best performance.

What sun exposure does Larissa Phlox need—full sun or partial shade?

Larissa Phlox thrives in full sun to partial shade, with at least 6 hours of direct sunlight for best blooming performance. This 2-3 foot tall perennial tolerates some afternoon shade but produces more flowers and stronger stems in full sun locations.

Does Larissa Phlox spread aggressively or stay compact?

Larissa Phlox stays nicely compact, forming bushy clumps that grow 2-3 feet tall and wide at maturity. Unlike some spreading perennials, it maintains its tidy upright form without becoming invasive. Plant with confidence in mid-border spots where you want reliable, contained growth. Available at naturehills.com.
