How are the heights measured?
All tree, and nothin' but the tree! We measure from the top of the soil to the top of the tree; the height of the container or the root system is never included in our measurements.
What is a gallon container?
Nursery containers come in a variety of different sizes, and old-school nursery slang has stuck. While the industry-standard terminology is to call the sizes "Gallon Containers", that doesn't exactly translate to the traditional liquid "gallon" size we think of. You'll find we carry young 1-gallons, up to more mature 7-gallons ranging anywhere from 6 inches to 6ft.
How does the delivery process work?
All of our orders ship via FedEx Ground! Once your order is placed online, our magic elves get right to work picking, staging, boxing and shipping your trees. Orders typically ship out within 2 business days. You will receive email notifications along the way on the progress of your order, as well as tracking information to track your plants all the way to their new home!
Why are some states excluded from shipping?
The short & sweet answer is: "United States Department of Agriculture Restrictions." Every state has their own unique USDA restrictions on which plants they allow to come into their state. While we wish we could serve everyone, it's for the safety of native species and helps prevent the spread of invasive disease & pests. We've gotta protect good ole' Mother Nature, after all.
The Rozanne Hardy Geranium is without doubt the most spectacular and beautiful of all the hardy geraniums available. Vigorous and easy to grow, it has perhaps the longest flowering period of them all, and what flowers they are. Large, open bowls of the most wonderful deep blue – a color always coveted and valued by gardeners. Topping the foliage in an abundance of glory, they keep coming and coming from late spring until finally stopped by the first frost. No groundcover can come close to the glory of this one, and yet it is hardy, reliable in returning the next year, and the year after that. Spreading into 2-foot sprawling clumps and rising almost as high in bloom there is no space in your garden that won’t be brought to life by this plant.
- Large violet-blue blooms with purple veins and a white center
- Rounded, deeply lobed leaves of dark green
- Fabulous as groundcover, in borders, pots and hanging baskets
- Grows in sun and partial shade
- Heat and drought tolerant
Grow the Rozanne Hardy Geranium in full sun for best blooming, but it also grows in partial shade well. Best in moist, rich but well-drained soil, established plants are drought tolerant, and heat resistant as well. Deer, rabbits, pests and diseases leave it alone and it needs little care or attention. Remove the flowering section of stems once they stop blooming, and cut back in fall to the basal clump of leaves.
- Plant Hardiness Zones 4-8
- Mature Width 2-3
- Mature Height 1-2
Hardy Geraniums are terrific garden plants, for ground cover and for the front of all your beds. The flowers are only half the story, because they have handsome foliage too, but if it’s flowers you want from your garden plants, then you cannot be without the Rozanne Hardy Geranium. Widely recognized as incredibly floriferous, it blooms not just in spring and early summer along with most of the rest, but also all through summer and even into fall. They are glorious flowers too, a profusion spread across the whole plant, and 2-inch cups of wonderful violet-blue – and an almost perfect blue at that. It is hardy, reliable and easy to grow too, as easy as any other hardy geraniums. Rising almost 2 feet tall and covering an area of 3 feet, just one plant makes a statement. But of course, planted over a larger area it’s a very bold statement, and a wonderful display of one of the very best garden plants around.
Growing the Rozanne Hardy Geranium
Size and Appearance
The Rozanne Hardy Geranium is a perennial plant that grows back from a fleshy root each spring, producing a vigorous mat of leaves and stems 2 and even 3 feet across within just a few seasons. Allow for this size when planting. In spring it stays low, but quickly pushes up many stems to stand 1 or 2 feet tall when in bloom. The leaves are 3½ inches across, divided into 5 radiating lobes, each one serrated, creating a very attractive leaf. It is softly hairy on both sides, and mid-green marked in greenish-yellow, giving it a marbled look. The large blooms are carried on branching stems that rise above the leaves and spread upwards and outwards. Each bloom is an open bowl of 5 petals, 2 inches across, colored violet blue shading into a small white zone in the center. Some of the very first blooms can be tinged pink, but the full color quickly develops. The petals have a soft, silky look and feel, and they have red veins radiating across the surface – especially noticeable in the white zone. Flowers come in succession, starting in early summer and appearing more or less continuously into fall. This variety is widely recognized as the most abundant and continuous producer of blooms of all hardy geraniums, and it is often only a hard frost that stops it in its tracks. When flowers end they leave behind a long, narrow seed pod that gives this plant its alternative name of’ cranesbill’.
Using the Rozanne Hardy Geranium in Your Garden
Grow the Rozanne Hardy Geranium wherever you want brilliant and continuous blooms – everywhere, right? Plant it in the foreground of shrub beds, spilling onto paths and patios, or on slopes and in rock gardens. Grow it in formal beds or natural plantings – it simply looks great everywhere. From zone 6 onwards it can also be grown outdoors all year round in pots and planters – a great idea to replace all that planting of annual flowers.
The Rozanne Hardy Geranium is reliably hardy all the way from zone 4 into zone 8, with good resistance to both cold and heat.
Sun Exposure and Soil Conditions
For the best results plant the Rozanne Hardy Geranium in full sun. In hot zones it could take some afternoon shade, but this is not a variety for planting in shady places, as some other hardy geraniums are. It grows well in most soils, as long as they are well-drained, but of course for the best continuous blooming richer, moist soil are best. Established plants will tolerate some drought, but may stop blooming during that time.
Maintenance and Pruning
The Rozanne Hardy Geranium isn’t troubled by deer or rabbits and it doesn’t have any significant pests or diseases either. Removing old stems back to the foliage once they have bloomed will encourage more, but even that isn’t essential. Cut it back completely in late fall, once the leaves yellow and fade, and flowering is over.
History and Origin of the Rozanne Hardy Geranium
There are over 400 species of Geranium, mostly found in Europe and central Asia, and many species have multiple garden varieties. The Rozanne Geranium was discovered in 1989 by the late Donald and Rozanne Waterer, growing in their garden in the small village of Kilve, Somerset, England. They had many hardy geraniums growing, but as experts they believed it was the result of a cross between Geranium wallichianum ‘Buxton’s Variety’, an early-flowering plant originally from the Himalaya, and Geranium himalayense ‘Plenum’, a late-blooming and long-flowering variety of a plant that is also from the Himalaya. They gave it the official name of ‘Gerwat’ (the first three letters of the words ‘geranium’ and ‘Waterer’) and then patented it (accidentally?) with the name Rozanne (PP# 12,175) in 2001. That patent expired in 2021. The name Rozanne is therefore not the official name, or protected, and has become just a common name for this plant.
