Blooms to sweeten a winter’s day – luculia

Luculia gratissima ‘Early Dawn’

Here we are, a mere three days from the winter solstice and outside my window, rain is pelting down while thunder and lightning is keeping the dogs safely in their beds by the fire. So I bring you winter sunshine, in the form of luculia, with photographs I took just yesterday when the sun shone and the daytime temperature was around 18 degrees Celsius.

I am very fond of luculia with their heady fragrance and their balls of flowers. Perhaps they are a bit like the wintersweet equivalent for mild climates. These are not particularly hardy plants even though their original homeland is declared as the Himalayas and Southern China. Think not of high, snowy peaks but more of temperate, protected, lowland forests and by the time you reach southern China, it is distinctly tropical. Luculia are okay with cooler temperatures and a degree or two of frost but that is all. The will not survive much beyond that.

There is not a huge range of luculia – there are only five different known species and, as far as I know, named cultivars are species selections, not hybrids. We grow gratissima and pinceana, grandiflora is also widely grown but I have not seen intermedia or yunnanensis except on line.

I am not a massive fan of L. gratissima ‘Early Dawn’, which is a smaller growing species. That sugar pink flower is very… sugary. Also, when grown in full sun or high light levels, the foliage can take on autumn tones which are not a great foil to sugar pink. Too often, ‘Early Dawn’ is clipped into obedient, rounded stature. Let it grow as it wishes in woodland conditions and the foliage stays bright green giving clean contrast to the pink, while the shrub becomes willowy and graceful. That is when it looks best, to my eye, although it won’t flower as prolifically in shadier conditions.

Luculia pinceana ‘Fragrant Cloud’

‘Fragrant Cloud’ is a different species, being L. pinceana. It is larger growing with considerably larger flowers in pretty almond pink, a stronger fragrance, more rangy and open in its growth and if you prune it too hard, it is highly likely to die on you. If you like tidy, contained shrubs, this may not be one for you. ‘Fragrant Pearl’ is one we named, another L. pinceana selection that came to us as a seedling from our colleague, Glyn Church. It is much more forgiving than its pink sibling and will take harder pruning. Left to its own devices, it will be just as rangy.

Luculia pinceana ‘Fragrant Pearl’

We used to grow ‘Fragrant Pearl’ commercially and it was one of the quickest turnarounds we had. Most of the trees and shrubs we grew took 3 or even 4 years from taking the cutting before becoming saleable. We could get ‘Fragrant Pearl’ through in 15 months. We would take the cuttings from nursery plants as soon as the new growth had hardened in January. They rooted really quickly and with a high percentage in the propagation beds. We would pot them from root-trainers to finished bag size in late winter or early spring, stake and shape them in January and sell them in bud in March and April. ‘Fragrant Cloud’, the pink form of the same species, was nowhere near as easy to handle as a nursery plant and the reason we don’t have L. grandiflora is because it was not that easy to propagate from the cuttings Mark tried and we don’t want it enough to go out and actually buy a plant.

I can not advise on how to make the flowers last longer when cut. Sometimes they have held reasonably well, other times they have gone limp and flaccid within hours. This probably has more to do with the time of the day they were cut than whether the stems were crushed or sealed by burning. But we heat our house to such a degree in winter that there is no point in trying to keep cut flowers in a vase.

    I love the pinceana forms, and Fragrant Pearl in particular, but as you mention they haven’t liked being pruned. Taking off wayward side branches has often lead to partial or whole death as fungal infection runs down from the cut killing as it goes. Do you think it might be a matter of seasonal timing or a limit on the age of the wood being cut? In general pruning cuts are best done at the correct position and left unsealed but might this be an exception?

      I always cut back to a leaf bud, leaf junction or remove a branch entirely. And if I get my timing right, I pinch out new shoots to encourage bushier regrowth. But it is hard to bring back a leggy, old specimen.I haven’t noticed fungal attack but I may not have been sufficiently observant. May be best to ensure any pruning is done in dry conditions. Pruning paste may be worth a try, if you can be bothered (we never use it). I would be interested to hear how it goes, if you try it.

    The Early Dawn local to me has had a stellar year this year, smothered in bloom for at least the last month, but I just can’t reconcile myself to the colour. I have finally got my hands on a Fragrant Pearl. I assume pinching as it grows will help it fill out?

    I do not think of them as being so sensitive to frost. I was told that when I wanted to bring a single specimen back from Beverly Hills (in the Los Angeles region), but I am told that about many plants that I bring back with me. The spot where I saw them being installed happens to get somewhat cool in winter. It is just up the lower southern slope of the Santa Monica Mountains. (There are actually cultivars of apple that were developed for minimal chill that can be productive there.) Well, I never procured one, and have not seen one since, although I am told that those that were installed are doing quite well. I could not even remember what species they are.
