New releases of these ever-popular flowering plants (which have indigenous forefathers) appear every year, and the good news is that they have more compact but multi-branching growth habits, more abundant flowers and better disease-resistance – we thank the untiring and dedicated breeders for this. Due to their efforts and the growing skills of our local trade, we can fill our pots, barrels, window boxes and beds with the latest zonal pelargoniums, and plant up hanging baskets, window boxes and retaining walls with tough and trailing ivy-leaved pelargoniums.
Most of the modern varieties flower repeatedly throughout the year, but the natural flowering peaks are in spring and again in autumn when the temperatures are more moderate.
The best climate
In very cold regions, these plants should either be treated as annual summer colour or planted in very sheltered areas. In temperate, warm to dry regions your pelargoniums will be biannual or perennial, flowering and growing well for quite a few seasons before you’ll need to replace them with fresh plants. They will also flourish in humid, subtropical regions, but you should then be aware of the possibility of fungal diseases and treat the growing medium preventatively for it.
How to grow them
Although pelargoniums are easy to grow and quite tough, they have a few specific requirements to keep them in flower:
Position: Full sun is perfect, but a good few hours of morning sun and afternoon shade will also work.

The Malaise Of FOPB!
Living remotely from others leads to a bigger reliance on remotes and their confusing buttons. It is terrifying if you suffer from FOPB…
Fiery shades of red and orange make for a bold autumn display.
A Haze Of Purple
The evergreen ribbon bush, a compact shrub with dull-green leaves and abundant spikes of two-lipped deep purple flowers with darker purple spots, is a selection derived from Hypoestes aristata and was developed at the Walter Sisulu National Botanical garden. It carries the apt varietal name of ‘Purple Haze’ and is widely cultivated in gardens all over the country.
The Allure Of Lavender!
This herbaceous plant, a member of the mint family Lamiaceae, is so famous that its common name is even used to describe a colour. Most of us will associate the term lavender with a gentle shade of light purple that symbolises elegance, refinement, serenity, purity and luxury – the latter two probably due to the Latin word ‘lavare’, which means to bathe and to wash. One can just imagine how the conquering and decadent Romans bathed in bunches of lavender sprigs and flowers, draped their newly washed togas over the bushes to permeate them with the fresh smell, and stacked dried stems of leaves and flowers in dark corners to repel plague-infested fleas!
Magnolia grandiflora ‘Little Gem’
If cauliflower was a stock to trade, some would have made millions in the last few years as the humble cauliflower became one of the most versatile cruciferous vegetables in the kitchen. With an increase in the popularity of flexitarian, vegan, gluten-free, keto and plant-based diets, cauliflower is no longer only baked into a cheesy casserole, but spiced and grilled as ‘steaks’ on a braai, mashed, riced, sauced, powdered, blended and made into pasta or a crispy pizza base. There are not many vegetables that can do all that!
Mushroom plant (Rungia klossii) is a bushy perennial with crisp, mushroom-flavoured leaves that are good for adding to salads or for cooking. Steam just before serving so that the leaves don’t lose their fresh green appearance.
A passion for roses
For five generations of gardeners, maybe more, Ludwig Taschner has been the friendly face of rose growing.
Time For Wild Hyacinths!
We told you in January that planting bulbs would be a great trend in 2021, so March is a good time to kick off your annual bulb planting quest with the indigenous wild hyacinths, also called Cape hyacinth, Cape cowslip and, more botanically correct, Lachenalia. Between South Africa and Namibia there are more than 120 natural species (some of which are sold in flower by specialist nurseries), but there are also many desirable hybrids bred by commercial bulb growers that are readily available in bulb form from the end of February.
Slugs? Hosta la vista baby!
