A reliable, star attraction
Begonias, part of the Begoniacea family. have been around for many years and although some varieties can be grown indoors, typically here in Britain they have become one of our most commonly grown summer flowering perennials outdoors. Begonias, named by the famous botanist Charles Plumier, are well worthy if their place in the garden, flowering continuously through the summer months, often right up until the first frosts of autumn.
When looking to fill your summer hanging baskets we often look to traditional trailing plants such as Surfinia, Million Bells and trailing Geraniums. A superb way of mixing things up while still achieving excellent blooms is to try some trailing Begonias.Cascading or Pendula Begonias produce giant sized flowers through the summer months and are easy to plant on arrival. Ideal for hanging baskets mounted to the wall or for containers raised of ground level. For the largest blooms possible try growing on the Giant Exhibition sized 5/6cm tubers, guaranteed to produce up to 100% larger double flowers from each tuber. Chosen and used by the professionals at most garden shows and in large country homes, they are certainly worth that little extra money.
You can add a touch of fragrance to your trailing baskets with our range of Begonia Odorata tubers, which come in a range of colours. You can choose from ‘Odorata Red Glory’, ‘Odorata Pink Delight’ or the hard to ignore classic white ‘Odorata Angelique’. For the premium ‘Shower Bouquet’ effect we recommend the Balcony Begonia Collection, Gold and Pink ruffled edged petals, with a gentle cascading habit. Mix together for a wonderful blend as illustrated.
Try planting three 5/6cm tubers into an average hanging basket, in moist compost for a display that will cascade beautifully over the edges. Begonias are great lovers of moisture and during dry weather they should be watered in the early morning or the evening.
Give your patio pots and containers a splash of colour
The versatility of Begonias makes them great for the patio as well as in flower beds. By growing in pots and containers around the garden you can easily add a dash of colour, while having the added benefit of being able to move them around if the need arises. You can choose more compact and upright varieties which can be grown in pots, such as Double Flowering Begonias or for larger blooms with serrated edges why not opt for Fimbriata Begonias, a perfect choice for troughs on a windowsill.Non stop Begonias are compact enough for this but also are quite vigorous growers, so can virtually flower constantly through the entire summer, non-stop as the name suggests. Reaching heights of only 20cm they are great for the front of a border, with some Dahlias or Gladioli towering over them.One of our favourite varieties to grow in pots are the often ignored, but impossible to forget once you grow them yourself, ‘Maxima Switzerland’. The truly sensational dark leaves contrast effectively with the scarlet red flowers. A real treat for the container! ‘Bertinii Skaugman’ will offer your some of the most surprisingly large sized plants possible from a single tuber. ‘Flamboyant’ produces small flowers, but more than makes up for that by the abundance in which they appear.
Some top tips for success with Begonias 1. Begonia tubers may be started into growth from February onwards. The easiest way is to put them into shallow boxes containing a mixture of loam, leaf mould and sand. Meanwhile, prepare the potting soil.
Good top soil mixed with one-sixth part of manure should form the basis. To this prepared soil add leaf mould in a proportion of 1 part leaf mould to 3 of loam and enough sand to make a fairly porous compost. Soot and bonemeal added to the compost will be appreciated. As soon as the shoots of the tubers are about 2cm long pot them up in 15cm pots and place them into larger pots as the roots reach the sides of the pot.
2. Plant in full sun or partial shaded areas. The more access to sun, the more vibrant the colours will be.
3. You can feed once every two weeks with a high potassium up until the blooms begin to fade.
4. Make sure they are watered regularly during the summer and that the soil is not allowed to dry out. Begonias love moisture and will use up quite a lot during the hotter spells in the summer.
5. Lift tubers after flowering has finished and the leaves have begun to turn yellow. Store in a dry, cool (but frost-free) location over the winter. Store in soil that is only a little moist and keep this a little moist over the winter (with irregular watering) to keep the tubers from drying out.
