Planting & Care

Where to Plant

Sunlight: This shrub performs best in full sun, requiring at least 6 hours of direct light daily to produce the densest carpet of yellow blooms. While it can handle partial shade, you will notice fewer flowers and a more open, leggy growth habit.
Soil: Aim for well drained soil that does not stay soggy after a rain. If you have heavy clay, mix in some organic compost to improve drainage, as "wet feet" can lead to root rot in this variety.

Watering Requirements

During the first growing season, water your St. John's Wort twice a week to help the roots dive deep into the soil. Once the plant is established, it is remarkably drought tolerant and usually only needs supplemental water during extreme summer heat waves. If you let it get too dry during the budding phase, you might see smaller flowers or a shorter blooming window.

Pruning Tips

This plant blooms on new wood, meaning the flowers grow on the fresh stems produced in the current year. The best time to prune is in early spring before new growth begins, cutting the entire plant back by about a third. This act is like a "reset button" that encourages a flush of vigorous new stems and maintains a tidy, rounded shape.

Fertilizer Needs

Apply a balanced, slow release fertilizer once in early spring as the first green leaves appear to fuel the summer bloom cycle. Avoid using high nitrogen fertilizers late in the summer, as this triggers soft new growth that will not have time to harden off before the first frost. This late season growth is very susceptible to winter kill and can weaken the overall health of the shrub.

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.

Bright buttercups for butterflies on a bush! No color is as cheery as the color yellow, and very few flowers can touch Sunny Boulevard® for its bright yellow flowers. Proven Winners® ColorChoice® Sunny Boulevard® St. John's Wort (Hypericum x SUNNY BOULEVARD 'Deppe') is a beautiful and strong hybrid American native. It blooms all summer, offering a very long season of color with its bright yellow buttercup-type flowers.

This shrub is lacy and soft on the outside, with its soft grey-green leaves and graceful mounding habit, but it has an iron constitution. It is evergreen in all but the most severe winters. You can count on this plant as a mainstay in your garden. In the autumn, shiny brown capsules appear to add fall and winter interest to your garden beds and borders!

Don't let the cheery flowers and soft foliage fool you, this plant is a tough fighter! St. John's Wort makes itself right at home, even spreading out a little to form nice colonies! Cold-hardy throughout USDA growing zones 4 to 8 and grows into a tidy 2-3 feet in height and spreads a bit wider at maturity. St. John's Wort is also a beneficial herb and has long been used to relieve everything from anxiety to inflammation. While we don't recommend using landscaping Hypercum medicinally, just the sunny blooms and the sheer amount of butterflies that arrive are sure to lift your spirits!

Planting and Application:

Though you can prune up St. John's Wort and it will be fine with it, most people prefer the 'wild' native-looking accent it brings to your garden. St. Johns Wort maintains a tidy 'scruffiness' to formal plantings and cottage gardens, and even brightening garden beds as a backdrop! Sunny Boulevard® as well as fitting in perfectly in informal country borders. Any way you style it, St. John's Wort compliments your individual garden design!

Pair Sunny Boulevard® with other pollinator and native cultivar plants that will show off their graceful, natural form and fit into a naturalized planting! Baby Blue Eyes, 'Little Joe' Joe-Pye Weed, or Paprika Yarrow, for instance, are good companions and their colors will look great with that Sunny Boulevard® yellow.

The 3-4 foot wide-spreading nature of these plants makes them perfect for erosion control, on steep slopes, and en masse. Need to fill an area with sunshine and butterflies? Plant a few St. John's Wort and sit back and relax!

#ProPlantTips for Care:

St. John's Wort is not particular about soil pH levels and is particularly suited for urban conditions, pollution, etc. St. John's Wort is easy-care when grown in average, medium, well-drained soils in full sun to part shade. It prefers moist, rich, sandy loams and tolerates some drought. Deer seldom bother this plant! Just be sure to provide well-drained soils since Hypericum cannot tolerate wet feet! Apply a generous 3-4 inch thick layer of mulch to retain moisture and insulate the root system from heat and winter's chill. Sunny Boulevard® blooms on new wood, so prune in early spring to clean the mound and control its size and shape.

Frequently Asked Questions

What is the mature height and width of Sunny Boulevard™ St. John's Wort?

Sunny Boulevard™ St. John's Wort reaches 2-3 feet tall and spreads slightly wider at maturity in zones 4-8. This native shrub naturally forms colonies over time, so give it room to spread for the best naturalized look.

Is Sunny Boulevard™ St. John's Wort drought tolerant once established?

Yes, Sunny Boulevard™ St. John's Wort is quite drought tolerant once established. This tough hybrid has an "iron constitution" and thrives in zones 4-8 despite its delicate appearance. Once the root system develops, it requires minimal watering and actually prefers well-draining soil.

How do I prune Sunny Boulevard™ St. John's Wort, and when is the best time?

Sunny Boulevard™ St. John's Wort tolerates pruning well but looks best left natural. Prune in late winter or early spring before new growth begins if you want to control its 2-3 foot spread. Light pruning maintains its graceful mounding habit while heavy pruning works for formal gardens.

Is Sunny Boulevard™ St. John's Wort deer resistant?

St. John's Wort is generally deer resistant due to its natural compounds that deer tend to avoid. This tough shrub's iron constitution includes natural defenses that make it unpalatable to browsing wildlife. Plant it in zones 4-8 for reliable, low-maintenance color that deer will likely leave alone.

How should I space Sunny Boulevard™ St. John's Wort plants when planting multiple?

Space Sunny Boulevard™ St. John's Wort plants 3-4 feet apart since they spread wider than their 2-3 foot height at maturity. This allows room for their natural colony-forming habit while maintaining good air circulation. Shop at Nature Hills for this long-blooming native that thrives in zones 4-8.

Does Sunny Boulevard™ St. John's Wort need winter protection, like mulching roots?

Sunny Boulevard™ St. John's Wort is cold-hardy in zones 4-8 and typically doesn't require winter protection. This tough shrub stays evergreen except in the most severe winters. A light mulch layer can help in zone 4 or exposed locations.
