Planting & Care

Where to Plant

Sunlight: Give your Rozanne Geranium at least 4 to 6 hours of direct sunlight daily for the best flower production. While it tolerates partial shade, especially in hotter climates, too much shade will result in fewer blooms and leggy growth.
Soil: This plant thrives in well-drained, moist soil rich in organic matter. If you have heavy clay soil, amend it with compost or pine bark to improve drainage and prevent root rot, which this geranium dislikes.

Watering Requirements

During the first growing season, keep the soil consistently moist to help the root system establish, watering deeply once or twice a week. Once established, Rozanne is moderately drought-tolerant, but regular watering during dry spells keeps the foliage lush and the blooming continuous. Inconsistent watering often leads to browning leaves and a pause in flower production.

Pruning Tips

Rozanne blooms on new growth, so you don't need to worry about cutting off future flowers. If the plant starts looking scraggly or stops blooming in mid-summer, shear it back by about one-third to encourage a flush of fresh, tidy foliage and a second wave of blooms that lasts until frost.

Fertilizer Needs

Feed your geranium with a balanced, slow-release fertilizer in early spring as new growth emerges. Avoid high-nitrogen fertilizers late in the season, as they push leafy green growth at the expense of flowers and can leave the new stems 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.

Looking for a wonderfully showy flowering display that lasts and lasts at ground level? Easy-care Rozanne Hardy Geranium, (Geranium x 'Gerwat') features beautiful, 1-inch violet-blue blooms through the growing season. Rozanne is the most versatile, long-blooming, heat and humidity-loving hardy Geranium you can buy!

In 2013, the esteemed Royal Horticultural Society of Britain named Rozanne the "Plant of the Century". It took home the top title in the Chelsea Flower Show's 100-year history.

So...what's so special about Rozanne Hardy Geranium? First, there's the bloom time. Deeply colored in shades of violet-blue, flowers with large white eyes begin appearing in late spring/early summer and keep coming in profusion until frost. Much to the delight of your many pollinators!

Rozanne grows low and spreading, beautifully mounded and covered with the most incredible flower display of sterile flowers that will not produce any seed or spread to areas where you did not plant them. Deep-rooted plants, Rozanne Cranesbill are strong and persistent in the landscape.

Oh, and the deeply cut leaves turn a nice, bronzy-red fall color, too. It will polish up the look of your plantings with ease.

This is a sterile, clump-forming plant. It won't set seeds or outgrow the mature spread listed in the Plant Hightlights. Many Geraniums fizzle in the heat and humidity of summer, but not Rozanne. Hardy throughout USDA planting zones 4 to 8, Rozanne is extremely adaptable!

Planting and Application:

This high-performance flower factory has a valuable, spreading growth habit that will softly fill the edges of your landscape. Add them in full sun or partial shade and enjoy blooms, blooms, and more blooms!

Create non-stop color and bold flower power in Rock Gardens and between pavers. Brighten up your foundation plantings. Add them in narrow new planting beds in front of mature evergreen trees.

Use them at the edge of your perennial plantings, or as a fill plant in wide, open areas as a spreading massed groundcover. Create a solid display by planting them 12 inches apart. You'll measure from the center of one to the center of the next.

Stagger additional rows in a zigzagging pattern, as needed. Plant the new rows 12 inches apart, as well. Mulch between plants and keep them weeded as they fill in for you. It won't take long!

This is a fantastic addition to borders and large patio containers in the South and Southwest. Tuck them around the edge of your large outdoor containers. You'll have a valuable "Spiller" that adds interest all season.

#ProPlantTips for Care:

For the best flower production, ensure that your chosen planting site receives at least 4 to 6 hours of sunlight a day. Rozanne Cranesbill performs best in well-drained soil. If your soil retains water, plant in containers or create a raised bed. Provide new plants with regular moisture until they are established when Rozanne then becomes fairly drought tolerant. A 3-4-inch layer of arborist mulch will boost your plant's health significantly and keep them stress-free.

You may want to lightly trim the plants in mid-summer if they need freshening up, but they simply will continue to bloom no matter what. In late fall after the plants have been exposed to several killing frosts, you can snip off the plants to the ground level and remove all of the season's tops so they are ready to re-grow in spring.
