November 2024 in the Southern Hemisphere
« on: November 04, 2024, 11:11:44 AM »
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,

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.

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 Robert,
those delphiniums are something else I  might try someday.
This Brodiaea came up as a volunteer - I wonder if it's Brodiaea elegans?

Hi Fermi,

The plant pictured “looks” like Brodiaea elegans. Making a definitive identification online is questionable. I would feel much more comfortable looking at the plant in your garden. If you have a large collection of Brodiaea species in your garden, hybrids are possible. In addition, seeds offered in seed exchanges can be misidentified, mislabeled, or be unintended hybrids. Such things occur much more frequently than we might want to believe. If getting a positive ID is important to you, my suggestion is to checkout the Calflora website (calflora.org). There are links to Jepson eFlora (ucjeps.berkeley.edu) where you can find dichotomous keys, as well as a detailed botanical description of each taxon.



Having written everything above pictured is a close up photograph of Brodiaea elegans ssp. elegans growing in its native habitat in El Dorado County, California. This photograph might be helpful for identification of the plant in your garden.



Pictured is another scene of Brodiaea elegans ssp. elegans in its native habitat in El Dorado County, California. It is one of the last Brodiaea species to bloom in our area each season. Brodiaea elegans grows abundantly on our El Dorado County farm property. It is mostly a low elevation species, however I have studied, in detail, a population that is found at an elevation of 5,125 feet (1,562 meters) in El Dorado County, California. This is well above the usual altitude range for this species.



Pictured above is Brodiaea elegans ssp. elegans in our Sacramento garden. If the species is well placed in the garden it can be quite effective in the landscape, harmonizing with other species, and making an attractive, naturalistic display. I have a number of interesting hybrids coming along, such as Brodiaea elegans x terrestris, as well as others. Brodiaea minor is another species I grow in our garden and enjoy greatly. It is a much more diminutive species and can be used in the garden in different ways.

I will be curious to find out what you discover about your seedling plant. I am always interested in how the Themidaceae perform in other gardens. May you have good fortune.

Hi Robert,
I suspect this is a hybrid between Brodiaea elegans and possibly B. coronaria which I also grow in pots.
Last week I visited a friend who lives just 25 km away and she can grow many cool climate plants I have no hope of growing here.
Here is her Meconopsis horridula and Roscoea humeana (or R. cautleyoides?)

Wow... your friend's Meconopsis horridula is gorgeous Fermi. I've tried it several times, but it failed at germination. How big (tall) is this M. horridula on your friend?

Thanks for showing me. A great pleasure here... at 4 Celsius, fog and rain...😉

Hi Fermi,

25 km distance from your home and your friend can grow Meconopsis! This is a tremendous temperature gradient. What is going on geographically that there is such a temperature gradient? A barrier of mountains or hills, a large elevation difference, proximity to the ocean, or something else?

Below are a few plants gardeners in your summertime hot, dry climate are likely already familiar with, as they thrive with such climatic conditions.



This seedling of Eriogonum ursinum var. ursinum is displaying some nice autumn leaf coloration. I will be planting this seedling in our cinder-block garden where the drainage is excellent. As I grow more seedlings of this species I will trial them in our loam soil. Many of our California native Eriogonum species grow just fine in our loamy soil without grit for additional soil drainage.



Pictured are two Eriogonum incanum seedlings. This species exhibits a great deal of genetic variability. I especially value tight growing plants with intensely silvery foliage. The plant at the bottom of the photograph exhibits this silvery foliage characteristic.

This species needs very quick drainage to do well. I will be planting these seedlings in our cinder-block garden too.



Eriogonum prattenianum var. prattenianum is another species that exhibits a great deal of genetic variability. I especially enjoy the prostrate, silvery foliaged variations of this species. Plants that form dense buns are desirable too, as many in the wild can be quite sparse.

The seeds were gathered in an intensely hot, sunny, rocky area with many andesite boulders. These too will be grown in our cinder-block garden until I have more plants to trial in our loam soil.



Pictured are second-generation seedlings of Penstemon azureus var. angustissimus. This species performs extremely well in our Sacramento garden. The goal here is to bring out the best qualities in this outstanding species that also performs well in summertime hot/dry climates.



This year’s crop of California native annuals is beginning to germinate. Some species benefit from fire/smoke treatment to enhance germination. Fire/smoke is not always necessary for germination. I have been developing lines that have a high germination rate without fire/smoke treatment. This year I have over 50% germination with Chaenactis artemisifolia. Eucrypta chrysanthemifolia var. chrysanthemifolia is another species that fire/smoke can improve germination I am working with. Being able to skip the fire/smoke treatment makes growing these species from seed much easier.

Hi Robert,
On the east coast of Australia is a line of mountains called "The Great Dividing Range" and the southern "tail-end" of it is Mount Macedon which is about 60km south of us. We are inland of the Dividing Range so weather that affects the east coast doesn't always affect us.
My friend lives in Kyneton which is at 520m above sea level (ASL) compared to Redesdale which is 290m ASL. Kyneton is more affected by Mount Macedon than we are.
I hope that explains a bit of the difference between our gardens - she's also a more experienced, diligent and capable gardener than I am!
cheers

This is an amsonia grown from seed as A. jonesii but I'm not sure if it's true or maybe a hybrid,

1) This Moraea bicapitata still has a few flowers opening even though most have gone to seed and died down.
2) An unnamed cactus - maybe a rebutia?
3) When I saw this red beetle on a lilium, I nearly had a meltdown until I realised it was a ladybird and not a lily-beetle!
4) Another moraea - M. gracilenta - I was worried that this had died out as I hadn't seen it for a few years, but here it is blooming amongst the weeds in the rock garden!

Hi Fermi,

Thank you for your climatic and geographic information. The climatic conditions in specific areas of Australia are still an enigma to me, however your geographic information is helpful.

During the 1980’s I attempted to grow some Meconopsis from seed up at our Placerville farm. They were just some generic hybrids. I managed to bring one struggling seedling to bloom. It produced one very pale blue flower and then promptly died. Climatic conditions here appear to be very different from your area in Australia. Our farm is located at an elevation of ~ 455 meters. With the climatic changes that have taken place during the last 40-50 years growing Meconopsis at our Placerville farm is completely impossible. In our region I would have to be at an elevation of 2,000 meters before climatic conditions would make the cultivation of Meconopsis possible. This region is ~ 60 km east of our Placerville farm in the Sierra Nevada Mountains.

Most of our native bulbs including most (but not all) of our Calochortus species are still dormant. I am hoping that the first set of Calochortus hybrids bloom this coming season. They are based partly on a line of Calochortus luteus originally from the Deer Creek Hills where the Sacramento Valley meets the Sierra Nevada foothills. This is still a botanically rich area. Brodiaea coronaria can be found in these habitats with annuals such Escscholzia lobbii. Vernal pools are common and represent a very specific habitat with specific plant species associated with them. It is in these vernal pool habitats where Brodiaea nana is found. This species has similarities to Brodiaea minor, however they are quite distinct and occupy completely different habitats. Brodiaea minor, in our area, is almost always found growing on Serpentine or Gabbro where there is very little competition from other species, especially non-native invasive grasses. Brodiaea minor is frequently seen with Lewisia rediviva var. rediviva as well as Eriogonum nudum var. nudum and the attractive spring annual Platystemon californicus.

I am still working on my new line of Gilia capitata with an extended blooming cycle into the late summer. This line is based on ssp. mediomontana and pedomontana, both of which are commonly found in our region. Progress is slow. It will take time until I am satisfied with the results.

Great to see so many fine plants. Thank you for sharing.
