South African Flowers in the Fall Garden

Gorteria diffusa

Leonotis dysophylla

Ursinia nana

Nemesia sp Verlatenkloof

Arctotis fastuosa

Diascia hybrid

Berkheya hybrid

Senecio sp

Ceratotheca triloba white fl form

Berkheya cirsiifolia

Fall is a strange time of the year, some plants are fading away while others burst into bloom as the cool air invigorates them.  This fall was especially dry and sunny, and frankly odd for us but much preferred to our more typical rainy and gloomy Octobers.  September is usually the last decent month, but we had a nice October and November has not been particularly bad either, though frost has finally struck and put an end to tender plants, such as the Ceratotheca triloba shown above.  Still there are many plants that tolerate some frost, especially South African plants from habitats where frost might occur during their growing season.  Thus Ursinia nana, Senecio sp (both of which I collected seed of myself back in 1993), Arctotis fastuosa, and Nemesia sp Verlatenkloof (a sp collected by Panayoti Kelaidis and now, in my self sowing strain with some N caerulea genes mixed in) continue to look great even after a couple of frosts in the upper 20s F.  The Gorteria diffusa survived all summer and took off as fall approached, it did well after the first frost but is now looking tattered after another round of frosts. A Berkheya hybrid with pale yellow flowers appears to be one between B radula and perhaps B purpurea, its leaves are more prickly than pure radula but the flowers are closer to radula than any other species I grow.  B. cirsiifolia in the school garden looks great even out of flower with its attractive foliage, in mild winters it may remain evergreen but most often it dies back to some degree before regrowing again.  The Leonotis dysophylla flowered just before the first frosts, so I cut the flowers and brought them in along with some tall marigolds, they looked quite nice on our table when we had some folks over for dinner soon afterwards.  The diascia hybrid is, admittedly, just one of those things from the local Home Depot (or as Panayoti refers to it, Home Despot), it has survived a few frosts but I doubt it will be as tough as some of the species are, notably Diascia fetcainensis, which seems to be the hardiest of them all, at least among the ones I have tried.  I transplanted a piece of it from my school garden to my home garden and it is taking, so I anticipate it will make it through the winter just as it has done at school for the last three years.  I've also planted out lots of young Crinum bulbispermum and Nerine bowdenii in the backyard gardens and quite a few Kniphofia in what was part of the front lawn, so I hope for a mild winter and plan for an exciting new growing season next year.
There are many more things to try in the garden next spring from my well stocked refrigerator full of seeds, and quite often new seeds worth trying become available from South African vendors such as Silverhill Seeds and Lifestyle Seeds.  Its fun growing things that no one even knows about, let alone think is possible, in my garden.  Novelty is one of the fun things about gardening, and one thing is for sure, as my home gardens continue to develop, they most definitely will not be like anything else in the neighborhood!

Do you have any hints on how to germinate Berkheya radula?

Hi Lloyd,
Berkheya radula has no special germination requirements, it will germinate at normal room temps but I have also seen self sown seedlings germinate in spring in my school garden. Note that it is difficult to tell fertile from infertile seed with most berkheyas and one should grow multiple plants from seed to get viable seed.

I've tried multiple ways/many times with seeds from different suppliers with no luck. If you have any viable seed, I will pay you for it.

Lloyd, I should get more viable seed this summer, they are in bud now. Let me know if you still need some.
