In their natural environments, begonia species originate mainly in the tropical and subtropical areas of the world, including South and Central America, Africa and Asia.

Sadly many of these natural habitats are being bulldozed, and the Queensland Begonia Society members are dedicated to growing the species that would otherwise disappear.

No begonia has ever been discovered growing naturally in Australia. However, we have many keen begonia growers who do have, amongst their collections, many of the threatened species from other lands, which will be featured at the show.

Some of these will grow here under our normal conditions and others require very special cultural conditions and need to be grown in terrariums to survive here. These will also be featured at the Show.

On display will be hundreds of the beautiful hybrid varieties that are favourites of most gardeners who love the colourful and varied foliage and flowers of these spectacular plants. Many of these hybrids have been created and introduced by our own Queensland members and also other Australian growers. Thus, new varieties are introduced into our collections.

Experimental Cross of Rex and Tuberous Begonias


Experimental Cross of Rex and Tuberous Begonias
Mcleod Valley Greenhouses: This is grown in canada and I took several years to create. The flowers are not on the rhizome, but on the elongated stems. The stems are not flat to the soil in this hybrid. This is not FAKE! 23 February at 02:14

John Boggan Very interesting, I’ve never seen a double-fllowered rex hybrid but there’s no reason why they shouldn’t exist. Come to think of it, I can’t think of any begonia from any of the Asian groups that have double flowers.

Mcleod Valley Greenhouses Sorry Ive not replied, James Missier, the rex line I was working with had a few flowers with extra tiny petals, so over the years I kept selecting and backcrossing these. The originals came from my mum, who was a begonias nut for years. They were not named back then, and so complex that the actual ID was obscure even then. Of course when I started to see results the excitement rose and a veritable sweat broke upon my weary brow, but I kept going. It’s all about the journey of discovery. These are addictive. About lowland growing I don’t know where you live, I don’t have any knowledge how they would do, but my summers are hot and dry. No mildew problems at all, so far. Cheers!

Experimental Cross of Rex and Tuberous Begonias [1]

Mcleod Valley Greenhouses: Yes but have not sold any, just playing with it to see the best ways. The line also was selected for years to have flowers on top. I think the poor rex bunch have been a bit messed up with breeders not wanting to see flowers, or maybe the flowers were not long lasting so I understand this from a growers viewpoint. I wanted to change all that and have both long lasting flowers that were presented on top.

Mcleod Valley Greenhouses: John Boggan, thanks for your thoughts. Here is an experimental cross with tuberous. Only one or two in a thousand turned out to have decent flowers that lasted and were of quality.

Begonia sinuata var pantiensis with pinkish flowers form spotted!!!


Orchids and the City

Begonia sinuata which is also known as the sparkling begonia is widely distibuted in parts of South East Asia – from Thailand to unfortunately only to Johor without crossing over to Singapore. It is one of the most common begonia in Malaysia and are oftern found on damp vertical rock faces near waterfalls. This begonia is the only annual begonia in the Peninsular of Malaysia. It usually dies towards the end of the year and they regenerate by seeds and also from its basal tuber and leaf bulbils. There are 2 varieties that are recognised by world foremost Begonia Expert -Ruth Kiew.

First is the var sinuata -which has deeply incised leaf while the second is the var pantiensis which has a nice maple leaf form!!

Begonia sinuata var pantiensis is able to adapt to Singapore weather.

Begonia hemsleyana: SPECIES TALK – MARCH MEETING


Begonia hemsleyana, Bot. Mag. 125: t. 7685 (1899).
Source: Curtis Botanical Magazine; Author: Hooker

Carmel Browne presented the Species Talk on 16 March 2013.

The area of distribution of this species extends from northern Burma to the Chinese province of Yunnan in moist, upland forests.

B. hemsleyana was introduced to Kew Gardens by way of seed collected in south Yunnan in 1899. It was named in honour of William Hemsley who worked on Chinese plants at Kew at that time.

B. hemsleyana is rhizomatous, jointed at or below the soil with erect stems. The leaf blade is palmately compound, glossy green, sparsely hairy between the veins, paler green beneath with a reddish tinge. The petioles are pink with short, woolly hairs. Flowers are pink and fragrant.

I chose to speak on this species today because this is only the second time it has flowered for me. It has been described as difficult. From my experiences, I have found it requires a cool, moist, well lit situation with good air movement. Because it naturally produces short, closely spaced stems, good air circulation is essential to keep fungal diseases at bay. A well-drained premium mix that is allowed to dry between waterings suits B. hemsleyana.

B. hemsleyana, B. rex, B. pedatifida and B. circumlobata are closely related and all belong to section Platycentrum. B. hemsleyana has been successfully crossed with Rex Cultorum begonias. B. ‘Raspberry Swirl’, B. ‘Picasso’ and B. ‘Hula Skirt’ are the results of such crossings. I do not know if these have ever been grown in Australia.

Begonia parilis: SPECIES TALK – APRIL MEETING


Begonia parilis

Photographed at the Royal Botanic Gardens Sydney (Australia) in December.
Sourced from commons.wikimedia.org, this photo is originally from Gardenology.org.

Di Schulz presented the Species Talk on 20 April 2013.

The following was taken from a Begonian of 1968.

The stems and branches of B. parilis are soft and hairy. Its leaves are velvet-like in texture, olive-green, red at the margins and red flushed beneath. Flowers are pink or white.

From Know Your Begonias by J Krempin.

B. parilis was discovered in Brazil in 1953. It is known as the zig-zag begonia. It is thick-stemmed, grows to 1 metre with zig-zagged branches and medium, narrow, shining green leaves, red beneath. Arching clusters of white flowers with yellow stamens appear in summer.

Begonias: The Complete Reference Guide by Thompson & Thompson has this to say.

B. parilis is a versatile begonia that is attractive whether it is staked or not. Although this plant branches naturally, early pinching will produce an even fuller plant. It can be grown effectively in maximum sunlight according to the locale, or it can be grown in a semi-shady position, making an interesting foliage plant. However, it will only bloom when there is sufficient sunlight.

Forest Garden

I love begonias.  That may sound like a strange obsession for a “forest gardener”, but it is my strange obsession.

I remember buying a hanging basket of blooming angel wing Begonias with tiny dark burgundy and green  leaves at the  farmer’s market when I was living in a third floor walk up.  It made my small screened in porch more beautiful, and made me happy.  Since then, I’ve always had a soft spot for adding beautiful begonia plants to my collection.

There are thousands of cultivars in the genus Begonia.  Whether grown for their outrageous leaves or their abundant bright flowers, Begonias can be found from tiny to tremendous.

Begonias work in a forest garden because they appreciate shade.  Although some, like the new Dragon Wing cultivars and Begonia “Bolivienses” can take hours of sun each day, most are quite happy growing in permanent shade.  They also require very little care.  Most like to…

Propagating Cane Begonias


Betty Vander Poorten (10)
Doing it my way!

I take tip cutting about 12-13cm (5in.) in length. Always go to a node which has not flowered. This hopefully will give you a nicely shaped plant. If you cut at a node which has flowered, the plant will not branch.

My propagating mix for canes is potting mix 80%, perlite 20%. I have also used straight vermiculite with great success. I always use striking powder, a habit from nursery days in Victoria because I believe it to be beneficial. Lots of growers do not use this powder.

August for me is the best time to do cuttings, but I have had success in autumn before the cold weather sets in. On an east facing wall I have large terracotta pots filled with lovely canes which get sun till midday in summer – the more sun, the better the flowering.

In August I cut back to four nodes in the centre of the plant and three around the edge. This gives a lovely flowering plant by the end of November/December. Fertilise with Osmocote Plus. If things are working your way …. Don’t change!

 

Pot Sizes


Angelwing Begonia in a pot

A potted angel wing begonia (Begonia aconitifolia × B. coccinea).

We have always been told that begonias like to have their root system fairly contained and it is disastrous to ‘overpot’ them. Most of the experienced growers who have written books or articles on begonia culture have stressed this point. I have often recommended using a smaller pot for growing a begonia in than one would see for an ordinary pot plant. Why? Because everyone says so and it has always been the rule. This is understandable in cool and or wet climates, or in glass houses which have a controlled atmosphere. Under such conditions the transpiration from the leaves and evaporation from the soil is greatly reduced.

The potting mix will hold its moisture for a longer period, and unless there is a large root system in relation to amount of soil, the water contained in the soil will become stagnant and the soil “sour”. I have found that it is important to pot newly rooted cuttings and small seedlings into very small pots because they usually have limited root systems and require oxygen (air pockets) to grow. It would be unwise to repot a begonia into a large pot at the beginning of winter when the growth rate is going to slow down and the plant will require very little moisture.

Excepting the previously mentioned conditions, I believe that in our hot, dry summers we can use larger pots than those we have been using. At the beginning of last spring my rexes in 12cm pots needed repotting. I know if they were put into 15cm pots that they would soon need larger ones and didn’t relish the thought of doing the job twice, so I rashly potted them into 20cm squat pots. I could hardly believe how rapidly they grew and they are still growing and looking lovely.

Over the years, I have always allowed seedlings and cuttings to grow quite large in 6cm pots before placing them in 12cm pots. Last season quite a few were potted on which I didn’t think were really large enough. The same results occurred – before I knew it they had to go into larger pots. Naturally if plants are going to grow larger and faster they will require more nourishment and I know that I do fertilise my plants more than the experts recommend. It has often puzzled me why they advise using liquid fertiliser at ½ to ¼ or even 1/8 strength. Even on tiny seedlings I use Phostrogen at full strength and they GROW.

Maybe compared to the USA we can use larger pots because of evaporation and stronger fertiliser because of more frequent watering and more rapid plant growth. Another contradiction I have discovered is in the depth of containers.

I had some pots delivered and it wasn’t until the carton was opened that I discovered that they were deep 12cm pots – not squat. They were used and the plants did well, soon sending their roots out through the bottom drainage holes. The roots of our plants may develop more quickly because they have to forage when our mix becomes drier between waterings. I was amazed to receive a letter from a grower who was lamenting the fact that she had pruned her canes right back at the beginning of LAST season and needed to have them looking good for a special event at the end of NEXT season. I always severely prune my canes in early spring and they are usually lovely by autumn. Sometimes they need to be trimmed in between. It must indicate that our plants do grow more rapidly.

Please do not start putting all your plants into huge containers. I would suggest that you experiment with a couple of plants that can be easily replaced.

 

Understanding Mildews


Powdery mildew, species Podosphaera fusca

Powdery mildew, species Podosphaera fusca

Fungus and mildews are always a problem during humid weather. Understanding how they grow can help when you are trying to control them. Fungi are often visible to the naked eye and are often named for their appearance.Powdery mildew is a group of related fungi, usually showing as whitish spots on leaves or new shoots. They live on the surface and send hollow tubes into the plant to suck out nutrients. Some powdery mildews attack a range of plants – some only attack one plant, or at the most, two or three. Powdery mildew is worse in humid weather, and once it has got a hold, it will keep growing, even in dry weather.

Downy mildew is also a group of related fungi, also worse in humid weather. The infected patches appear first UNDER the leaves. Downy mildew grows within a plant and sends out branches through the victim’s stomata (the microscopic openings in the leaves) to create pale patches on the leaves. The problem usually disappears in dry weather, or sometimes if you improve air circulation or stop overhead watering.

Spacing plants to allow good air circulation will help to control some fungal diseases. Environmental problems such as heavy rain, very hot sunshine, strong winds and consistently high night temperatures can also lead to the development of these diseases. The soil should be kept rich in soil organisms to provide conditions that are favourable for the vigorous growth of beneficial fungi and bacteria that will feed on other more destructive types.

Begonias Grown by a Queensland Begonia Society Member

Mrs Betty Vander Poorten has been a member of the Queensland Begonia Society for many years, during which she has grown numerous begonia cultivars in green houses built by her husband, Hals.

CULTURE NOTES – APRIL MEETING (from Winter Journal 2011)

I was introduced to the world of begonias when a friend gave me a piece of a gorgeous B. ‘Silver Jewell’ she had in her home. Soon after we went to an open garden at Victoria Point where there was a lovely B. listada. The owner very generously gave me a piece of her plant. I was seriously ‘hooked’ when I went to the annual Begonia Show soon after. My family is surprised that my interest has not waned!

I have over the years tried various growing mediums and have now arrived at putting down my leaves in either washed river sand only or a mix of two parts washed river sand, one part Perlite and one part coir peat. The latter mix I find is excellent for cane cuttings. I find that if I use a root growing hormone powder or pure unadulterated honey to dip the cuttings in, it encourages quicker propagation. Unlike my earlier efforts, I now wait until the plants are really well established before I transplant them.

I now take care not to overpot. I also use small stones to weight the plants down, instead of using sate sticks.

I have lost many begonias by being too generous with feeding. Every so often, I use Confidor to prevent bugs and caterpillars from feeding on them. I use Baycor for mildew and have recently started using a concentrated form of Seasol called Eco-Cweed. This is in powder form. Half a teaspoon is dissolved in a little water and added to a litre of water. This is very good value and does not smell as much. Of course, it also takes up less space and is a lot easier than shaking a large quantity of liquid Seasol.
