Delosperma ‘Jewel of Desert Garnet’

Tracking down the correct name for this recently-hybridized ice plant cultivar was a bit of a pain. For a brief period of time, it appeared in some nursery catalogues (on-line, at the least) as Delosperma ‘Pink Ribbon’. However, it has recently been plant patented in the USA as Delosperma ‘Jewel of Desert Garnet’ (filed Sept. 9, 2011, approved March 12, 2013) and similarly approved under that name in the EU with Community Plant Variety Rights. In botanical nomenclature, there is a principle of priority where the first validly published name is the one that should be retained. In the International Code of Nomenclature for Cultivated Plants (PDF), however, Principle 5 states that names established under Plant Breeders’ Rights (presumably including US Plant Patents) take precedence over names formed under the provisions of the Code. So, what some know as Delosperma ‘Pink Ribbon’ has now changed its name. To make matters somewhat more confusing, it also appears to me that the rights managers are trying to treat “Jewel of Desert” as a trademark, and using ‘Garnet’ to identify this entity instead of its full cultivar name. I know people complain about scientific names changing, but horticultural names can be far more frustrating (for examples, see Tony Avent’s column: The Misuse of Trademarks in Horticulture).

Jewel of Desert Garnet ice plant was developed by Japanese-born plant breeder Koichiro Nishikawa. To give you an idea of how much he believed in what he was developing with this cultivar and other similar ones, he moved from Japan to Ecuador in order to decrease the interval between generations. Dedication!

Considered to be hardy to USDA Zone 7, Delosperma ‘Jewel of Desert Garnet’ is (from the plant patent) “characterized by its compact plant habit, its very floriferous and long blooming flowering habit, its high heat tolerance, and its flowers that are red-orange with pink centers and yellow anthers”. Sylvain Burgaud’s photograph shows the plant in habit.

Today’s photograph was taken last year at the Trial Gardens at the University of Georgia in Athens.

    Hola
    I enjoy this page. It is a cultural value to us who are learning to identify plants. However, much I would like to see the entire plant with its flowers. This image is abstract ….
    Saludos…

    I love a Delosperma, and this is no exception. What a brilliant, glowing color combo!

    Sergionebla, this is why links are included. I specifically included a link to a photograph of the plant in habit.

    What a stunningly beautiful photo. Thank you Daniel for sharing this on a rather dreary day. Jewel of Desert Garnet fits its name for sure!

    The attempts to misues cultivar names (registered or not under Plant Breeders Rights)as trademarks is a common problem in Australia as well.

    OMG, that’s a show-stopper. Absolutely gorgeous.
    Thanks so much.
    I took a look online and see that is actually being offered for sale by several nurseries. They are rating the hardiness all over the place…very inconsistent. Also, I do see that there are several ‘Jewel of Desert’ color variations for sale. I guess they know a good, new, thing when they see it.

    These are awesome plants. They do very well here in Tennessee. All they need is good drainage and sun. When it is very hot here in summer, I water these more often. They have been blooming since April here and are starting another show now. Surprisingly, the Jewel of Desert series can tolerate more shade than any other Delosperma I’ve grown. An ideal location in Zones warmer than zone 7 would be morning sun and some afternoon shade.

    Hello All,
    Thanks for all the nice words about the Jewel of Desert Delosperma’s. Concept Plants took over the royalty management of these varieties from De Vroomen who went out of business 2 years ago.
    Since then we changed the names in the correct names. It was a big mess and we also build a website http://www.delosperma.com
    Whenever you want to share your experience about the Jewel of Desert Delosperma’s. The breeder and we are always open for feedback on the performance. IF you want to receive the press release about this name change, you can email me.

    Jewel of Desert is not a trademark name. The varieties are only patented. We also do not promote them as a trademark but as a series.
    Thanks a lot!
    My best
    Peter van Rijssen
