We found this plant in the University of London Botanic College (opposite Royal Holloway College in Egham) in 1988. Callistemons have a reputation for being a bit tender and yet there it was having survived the ferociously cold winter of 1987/8 looking immaculate and with masses of strong red flowers. We took cuttings and all the 1000s of plants we've produced since then have been clones of that one plant. A good provenance. We find it easy and tough and remarkably unfussy about soil - as long as it's not too chalky. Very few Australian plants seem to like chalk. Maybe they don't do chalk in Australia.
It needs plenty of light to do its Tina Turner thing. This can be left to its own devices, trained into a little tree or even used as a hedge. It clips well, forming a nice tight hedge but you need to consider the consequences as far as flowering goes : it flowers on last year's growth so you really only want to clip it once every other year or you'll have limited flowering. Just because we're Architectural Plants doesn't mean we don't ever like flowers. In this case, they're so red and so prodigious, we like them a lot. I've seen closely related species (I can't imagine they're the same) grown as trees in the tropics and with their weeping habit and covered in red flowers, they're quite a site. Could we do the same in Sussex? Probably. It might require some pretty advanced Creative Maintenance but it's worth a try. We have some available with short trunks. That's a start.
They're also famous for their drought resistance - but this expression causes misunderstandings. Drought resistance in plants (except in Cacti) is because the plant is so vigorous, it has the ability to find water where others may not. So - very important - when first planted or if in a pot, water like mad! It may be potentially drought resistant but it's also a vigorous and therefore a thirsty plant. And remember to water the rootball, not just the surrounding soil.
The one in the picture is on the Ford road south of Arundel. The ones we planted in the garden at The Bodyshop HQ in Littlehampton in 1992 have also done exceptionally well.
Propagated by us from cuttings originally from the University of London Botanic Garden in Egham, Surrey in 1988. The entire garden seems to have disappeared.
IF IT HAS AN AMBER TRAFFIC LIGHT
Hardy in the Home Counties if sensibly sited (avoiding severe frost pockets, for example). Many Amber Labelled Plants are from cuttings from well-established plants that have survived many harsh winters in the South-East.
This is only meant as a guide. Please remember we're always on hand to give advice about plants and their frost hardiness.
Please remember that these coloured labels are only a rough guide.
General Point about Plant Hardiness: The commonly held belief that it's better to 'plant small' is perfectly true with herbaceous plants, but not necessarily true with woody plants. They need some 'wood' on them to survive severe cold - so plants of marginal hardiness in very cold areas should really be planted LARGER, rather than smaller, wherever possible.
