Planting & Care

Where to Plant

Sunlight: This Mediterranean native demands a minimum of 6 to 8 hours of direct, unfiltered sunlight daily. Full sun is critical for high oil content and vibrant purple flower spikes; planting in partial shade will lead to leggy growth and fewer blooms.
Soil: Grosso Lavender requires excellent drainage and thrives in lean, gritty soil with a neutral to slightly alkaline pH. If you have heavy clay, plant in a raised bed or a mound to keep the roots high and dry, as wet feet in winter is the fastest way to kill this plant.

Watering Requirements

During the first growing season, water deeply twice a week to help the root system reach deep into the soil. Once established, this variety is exceptionally drought tolerant and only needs supplemental water during prolonged dry spells. Overwatering or inconsistent moisture often leads to root rot or a decrease in the intensity of the aromatic oils in the foliage.

Pruning Tips

Grosso Lavender blooms on new wood, so the best time to prune is in late summer immediately after the flowers fade. Cut the plant back by about one third, shaping it into a tight mound, but be careful not to cut into the old, woody stems that have no leaves. This annual "haircut" prevents the center from splitting open and encourages a fresh flush of silvery foliage for the winter.

Fertilizer Needs

Apply a light dusting of bone meal or a balanced, slow release fertilizer once in early spring as new growth appears. Avoid high nitrogen fertilizers late in the summer because they stimulate tender new growth that can be easily damaged by the first frost. Less is more with lavender, as over-fertilizing leads to excessive leaf growth at the expense of those signature fragrant flowers.

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.

Adore the rich scent of Lavender? Grow the variety most used by commercial growers at your home!

Grosso Lavender (Lavandula x intermedia 'Grosso') is strongly fragrant (and is arguably THE most fragrant variety). It features hundreds of large, dark purple fragrant flowers on long, showy spikes.

That beautiful dark color and outstanding fragrance holds fast, even when the spikes are dried. If you craft with Lavender, you need to include this variety in your Herb Garden.

With a mounded, tidy form and very attractive foliage, Grosso puts on a magnificent display even when out of bloom. In the warmest climates, the silvery-green foliage remains evergreen for year-round interest.

Grosso is a natural hybrid between cold-hardy English Lavender angustilfolia and the ruggedly durable latifolia varieties that are seen in the Provencal landscape. Just give it well-drained soil and plenty of sunlight.

Once it is established in your landscape, it can produce hundreds of large purple flower spikes that grow 6 inches long. This beautiful plant, nicknamed "Fat Lavender" makes an incredible display from mid to late summer.

The calyxes cling tightly to the flowering stems when dried, making Grosso an excellent choice as an everlasting dried flower. Create pretty, highly scented soaps, distill into essential oil, dry for wands or sachets and include in potpourri.

The flower display starts in midsummer and continues through fall. Rabbits and deer tend to leave them alone. But you'll watch in wonder at how much butterflies and honeybees appreciate the nectar.

You'll never grow tired of this special plant. Let it delight you for years with rich scent and a lovely, bushy form. Order your Grosso Lavender today!

How to Use Grosso Lavender in the Landscape

This is a classic addition to the edge of sunny borders or along the length of gravel walkways. It will be a noteworthy "Thriller" in large outdoor containers on your patio, deck or balcony.

Try a low hedge around your Victory Garden. You'll elevate the look of your vegetable patch, and entice beneficial pollinators to boost your production in "Second Season" plantings.

Create a solid hedge by planting 18 inches apart on center, measuring from the center of one to the center of the next. Mulch between the plants with wood chips, or use landscape gravel.

If you have the space, create a wonderful mass planting by adding additional rows staggered off-center from each other. You'll cover the ground and create quite a legacy. Just ensure that your plants have good drainage in wintertime.

Will you be harvesting the flowers regularly in a home business? Create long, orderly rows like the professionals do. Expand the distance between rows to 42 inches apart for easy access.

Harvest your Grosso for culinary purposes, as well. Add to honey or vinegar to flavor sugary sweets or savory meats. Infuse water for a refreshing drink on a hot summer day.

Savor the fragrance by placing these special plants in high-traffic areas. Delight your guests with Grosso Lavender lining your front walkway. Add a single specimen by your back door.

#ProPlantTips for Care

This easy-care plant actually does best in poor soil with sharp drainage. No need to amend or improve the fertility of your soil.

Do not fertilize Grosso, either. Over-rich soil will cause the plant to be less fragrant. All Grosso Lavender plants really need is full sun and good air circulation.

Pay careful attention to watering only during the first year as it gets established in your landscape. After the first season, it will be tolerant of drought.

"Mound up" if your soil retains water in wintertime or if you live in humid climates. Add additional soil in a heap 12 inches tall and plant in that mound. Add an attractive landscape border to create a raised bed.

Prune to shape in early spring. You can periodically rejuvenate your plant by clipping a few of the oldest, woodiest stems back to the base. You'll soon see new growth emerge from the base.

Don't miss these beloved plants. These are in demand and are at a high-risk of sellout. Place your order for Grosso Lavender today!
