Geranium 'Gerwat'

Geranium 'Gerwat'

Thank you to Johnson Farms, Inc@Flickr for today's image of a hardy geranium. The original image can be seen here, and it was shared via the BPotD Flickr Group Pool.

The cultivar name of this hardy geranium is 'Gerwat', but it is sold under the trade designation Geranium Rozanne. Trade designations add yet another layer of complexity (and some might say confusion) to answering the question, “What is the name of that plant?” The Royal Horticultural Society has a tidy summary on trade designations and trade marks; it is worthwhile reading it to understand why a plant can have two or three different names on the same label (e.g., common name of Rozanne hardy geranium, cultivar name of Geranium 'Gerwat' and trade name of Geranium Rozanne).

For gardening information on this meritorious hardy geranium, visit the Kemper Center for Home Gardening's page on Geranium 'Gerwat' Rozanne or see this page from Blooms of Bressingham in New Zealand. Interested in geraniums? Visit the web site of The Geraniaceae Group

Small tidbit from the resource link from two days ago regarding Lomo-style images: I forgot to mention I discovered it via Darren Barefoot's weblog.

Botany resource link: Desmids in the Netherlands is a site dedicated to the unicellular green alga in the Desmidiaceae and Mesotaeniaceae. Includes a Desmid of the Month – I'm a fan of Euastrum humerosum, myself. Little green beauties.


Geranium 'Gerwat' - Z5-8 - Kemper Centre for Home Gardening

Blooms of Bressingham is in England.

Daniel, excellent photo of Rozanne .... geraniums being one of my all-time favorite low-maintenance perennials, I had been looking for G. Rozanne for awhile before I found some last year. They're doing beautifully in my garden ... just as promised. The blooms are positively flourescent in the semi-shade of afternoon.

On your botany resource link: wow! I love that website -- what cool photos of desmids. There is such a huge variety of forms. I'm sure everyone who checks out the photos of these simple organisms will find a favorite among them. The one I like today is this one.

Sure, the original Blooms of Bressingham is in England, but that page is from Blooms of Bressingham in New Zealand - seems like they are doing plant evaluations for New Zealand gardeners and have a separate web site and physical location.

Thanks, Maureen re: the desmids - the photograph, I can't take credit for, though. Thanks to Johnson Farms, Inc@Flickr for that!


Congradulations on UBC's blogging initiative.
Your Botany Photo of the Day has been like receiving a bouquet of flowers and box of chocolates every day.

They sell over here as well.

I planted this and a similar-looking one in a customer's garden to see if the less familiarly named one was really distinct. It turned out to have more appealing flowers. Will have to find out what it was being sold as.

Thanks for FINALLY settling the controversy of this pretty flower that appears in my garden and nicely fills in the neglected spots! Someone told me it was an hibiscus, but that didn't seem right. My geranium is a solid pink. Here's a link to a picture I took last month (August):


Excellent site, by the way!

SusanT - the flower in your photo is in the Malvaceae family (Hibiscus), not the Geraniaceae family (Geranium). It appears to be a plant in the genus Sidalcea.
