Most of us are probably familiar with the concept of standardising plants, where a central leader is trained so that there is a bare stem with growth at the top. Roses are one of many plants that can be grown in standard form and offer more options in the landscape of our gardens.
Standard roses are created at the time of propagation by growing the rootstock longer and budding the desired variety at the top. Creating this extra length of the understock involves more time and effort and is the reason why standard roses are more expensive than their bush counterparts. Standard roses are also double and sometimes even triple budded to allow a more rounded head to develop. Single head standards are often sold because one bud has failed to grow or has been blown out at the nursery – there is nothing wrong with these although they will take slightly longer to develop a decent rounded head.
450mm (1 ½ ft) – Most standards grown at this height are miniature and patio cultivars, although some shrub/groundcover type roses are also produced on this size stem and are called mini weepers
800mm (2 2/3 ft) – Most bush roses, including some Austins and Old Fashioned are grown this height. Shrub and groundcover type roses are also grown at this height as weepers
1800mm (6ft) – At this height, only shrub/groundcover type roses are grown as tall weepers. A recent variation of this height has been pillar roses, with a cultivar budded 6 – 8 times the length of the stem creating a pillar of colour.
Apart from your own preferences such as colour, form, fragrance and garden display, the main characteristic you need to take into account when selecting cultivars to grow as standards is their height. Not only will the flowers be that much higher, there will also be a greater chance of damage occurring from strong winds.
Short to medium growing cultivars are the best while taller cultivars and those with an upright habit are best avoided. Floribunda type roses often seem to the best as a standard as they are generally fit the above criteria and are quite free flowering as well
Some roses that I think would do well grown as standards are:
Hybrid Tea – Aotearoa, Auckland Metro, Blackberry Nip, Chartreuse de Parme, Clodagh McGredy, Glorious, Lasting Love, Love Always, My Girl, St Pauls Cathedral, Waimarie.
Floribunda – Absolutely Fabulous, Anniversary, Brilliant Pink Iceberg, Burgundy Iceberg, Dear One, Friesia, Iceberg, Opulence, My Mum, Princess of Wales, Serendipity, Strawberry Ice, Trumpeter, The Wedding Rose, Warrior.
Shrub/Groundcover – Escimo, Lavender Dream, Lovely Fairy, Phantom, Precious Pet, Seafoam, Sparkler, Starry Eyed, The Fairy
Miniature/patio – Beehive Gold, Dinky Pinky, Ice Angel, Kaikoura, Pretty Polly, Roma, Sweet Dream, Trinity, Wanaka, Whiteout.
Standard roses offer many potential uses in the landscape and we should all try and incorporate at least one standard rose into our gardens just to show how things can be done.
Patio and miniature standards (450mm) can easily be grown in containers provided you do the basics right i.e. water, fertiliser, a good potting media and an annual repot. Under plant with seasonal annuals and you will have a very colourful show. Potted mini and patio standards also make great gifts.
If you are going to grow standard roses of any type in pots, it will probably pay to have a very heavy pot or anchor it down by some means. I have heard several stories of pots being blown off decks by strong winds only to have the standard snapped as well.
In the garden, mini/patio standards can be used in many more situations than taller, bigger standards. Use them to edge a path or driveway, or cover up a low wall or fence.
Weeping standards and pillars are best used open their own as a focal point in the garden, either by their own or under planted with low growing plants.
Standard roses have few special requirements over and above that of any other rose you grow. The most important thing when growing standards and I can’t stress the importance of this enough is to ensure your standard is well staked. If it isn’t staked well, then there is a good chance it will be blown over or worse still, come apart.
So if you are planting standards, even if they are in a sheltered position, invest in some good quality stakes otherwise you will be wasting your money and time. If you are growing weeping roses, you can buy special frames shaped like an umbrella to train them on.
When it comes to pruning your standard, there isn’t much difference to your normal roses. Try and aim for a rounded shape when pruning otherwise any bits that stick out will become top heavy and bend. Also, avoid light pruning as this will result in more mass up top and will make it more susceptible to wind damage.
Standard roses are another way of growing the world’s favourite flower and offer different ways of incorporating roses into the landscape. Standard roses are propagated specifically for the purpose and come in several heights, although there is a good range of types and colours to choose from. They are just as easy to look after as ordinary roses but do need to be staked very well.
