Hesperanthas tend to get nipped by frost here before they have much chance to flower. For some reason they always seem to flower late in my garden. They’re usually described as an autumn flower. (I’ve also seen sites say that they’re a late summer flower. But I certainly wouldn’t say November, or if I’m lucky, October is ‘late summer’!)
Maybe the late flowering is because the climate here is much drier than they like and they wait for the late autumn/winter rains to get them started. (They like that elusive ‘moist but well drained’ position that we don’t have very much of. There is the choice of well-drained and dry or yet more well-drained and dry. Adding compost helps but creating it takes time.) Plants that like damper conditions have to be kept watered in summer. Perhaps if I water the hesperanthas more thoroughly, they’ll flower a bit earlier.
I really wanted to photograph this plant before the frost could destroy the flowers, so I kept it in a pot under glass*. That worked well and it stayed in flower for a few weeks. Having the flowers protected from the weather meant that they stayed in great condition for being photographed.
This is a trick I often try with new plants – it allows me to have undamaged flowers to photograph and can make it much easier to get at them for photography too. (Once plants are in a border, it can be difficult to get near enough to them without trampling on their neighbours.)
Now that the photographs have been taken, I can plan where to plant out this hesperantha (or ‘river lily’). It will probably be a lot happier – especially if I manage to create an area that can easily be kept well-watered for all the plants that like moisture. (A bit like a bog garden without the bog.) I think that might be a challenge for next year.
POSTSRIPT: I was amused to see that I’ve misled some readers by using a common phrase in UK gardening. ‘Under glass’ just means in a greenhouse, conservatory or cold frame. The hesperantha has been in the conservatory for a while and will spend the rest of the winter in the greenhouse. It’s interesting to see how phrases we take for granted don’t necessarily travel well, hehe!
