Grow From Seed / Re: arisaema seeds

« Last post by Leena on November 05, 2024, 09:07:38 AM »

Leena - your plant is Arisaema amurense (a very variable species, with many different forms in the wild and cultivation). Yours sounds like a good rubust plant. But you'd be wise not to follow Sulev Savisaar and circulate it under the name 'bockii' (either as a species name or cultivar name) as it will lead to confusion!

The reason being - in the latest version of the Flora of China, the plant that many people know as Arisaema engleri has been renamed Arisaema bockii. Valid arguements exist for naming this plant either 'engleri' or 'bockii', and depending on who you ask, you'll get different answers as to which name is correct (way above my pay grade!) Whatever this plant should be called, it has nothing to do with A.yunnanense, or A.amurense.

Thanks Ben.
Yes, this is a good and robust plant, and when I had googled it seems indeed that there are different plants under the name A.engleri, some which look a bit like mine, and some not. My plant does look more like A.amurense though it is more vigorous and bigger with different colour "flower" than my other A.amurense, but it is a very variable species. I haven't sent it's seeds to the exchange because its name hasn't been clear.

thanks Ben,

I'd realised it was a very fine specimen of amurense

Hi Leena and Veronique,

I just thought I'd jump in and try and clear up a few things regarding any confusion over the name Arisaema bockii and for anyone else reading (as the genus Arisaema has more than enough name confusion already..)

Veronique - I hope you can track down some fresh Arisaema seeds!

Flowers and Foliage Now / Re: November 2024 in the Southern Hemisphere

Yet another local xeric species I am working with is Allium campanulatum. Here in our Sacramento garden the flowers tend to be washed-out pale pink, however through selection I am hoping to find forms that will bloom consistently with deeper pink flowers in our low elevation garden.

All these plants thrive in wintertime cool/moist – summertime extremely hot/dry climates. They seem like they would be good additions to gardens in climates like yours. Likely gardeners in your area already grow these species, however if not, these species might be worth considering.

Hi Fermi,

Thank you for all the information.



Here in California I am working on developing forms of Triteleia ixioides with enhanced deep maroon markings on the petals. This is a characteristic I enjoy immensely. Currently I am using both ssp. scabra and unifolia in these hybrids. They are such easy plants to please in the garden, tolerant of a fair degree of summertime irrigation and/or completely summertime xeric conditions.

While on the topic of plants that thrive where summers are extremely hot and dry, here are a few other plants I am working with.



This is Delphinium patens ssp. patens growing in our Sacramento garden. This low elevation California native goes completely dormant during the summer. It is a xeric species that is not bothered by extreme summertime heat or drought. The forms that I grow bloom into the late spring, extending our garden’s bloom period before the garden goes into its summer dormancy.



The flowers of the species range in color from light lavender-pink through deep lavender-blue. Currently, I am working on my second generation of hybrids. I have selections that persist and bloom consistently each season in our Sacramento garden. Extending the color range is another goal.



Pictured is Delphinium hansenii ssp. hansenii blooming in our Sacramento garden. It is another xeric low elevation species.



My favorite xeric, low elevation species is Delphinium gracilentum. This species also has an extended range of flower colors.

Leena, I went to see what he said about A. bockii on the facebook group for Arisaema.
It seems to be an Arisaema engleri, the name bockii referred to an earlier but incomplete description. Perhaps it should be called Arisaema bockii/engleri.
 It's so beautiful!  :)Both the leaves and the flowers...

Thank you for this info! I didn't know it.

Harking back to the discussion with Robert in the October Thread, here are a couple of "Themids"
1 & 2) Dichelostemma volubile
3 & 4) Triteleia ixioides
cheers

November is the end of spring and we are hurtling towards summer.
There are still a lot of flowers coming before the garden goes into its "summer dormancy".
1) Tritonia crocata orange shades
2) Ornithogalum thyrsioides
3 & 4) Eremophila hygrophana
5) Herbertia lahue
cheers

Hi Fermi,

You seem to have a fine collection of Themidaceae. Are they used much in home landscaping in your area? It seems that they would be well adapted to your local climatic conditions.

Hi Robert,
Themids are not widely grown in Australia.
Some growers have spread a few around and some of the more flamboyant ones such as Dichelostemma ida-maia, grab the attention but they don't persist.
One of the Landscape designers in Melbourne contacted me about a project she is involved in with Melbourne University. They want to trial a number some geophytes along with perennials and shrubs for planting up an area which will effectively be a "roof garden". Brodiaea elegans was a themid that she wanted (and was supplied by a friend of mine) - I also suggested Triteleia ixioides and some of the selections of Triteleia laxa.
Triteleia laxa has been grown in Australia for generations - I think at least 60 years. The form advertised was 'Queen Fabiola' which was described as deep bluish-purple. However what has been sold is a light blue-mauve form which is probably closer to the original species. A number of years ago one nurseryman imported some of the Dutch selections of Triteleia laxa grown for the cutflower trade. I got a few of them and have posted pics of them in previous years, especially 'Allure' and 'Silver Queen' which have multiplied well.
cheers
