Lygodium japonicum

My Lygodium japonicum often looks a bit tatty with all its leaves turning brown, so I assumed it was effectively deciduous and would regrow from the ground each year. It has been my habit to cut the plant right back to the ground each spring. This year, the bottom half of the leaves have died back but the top half of the plant is still green, if a little “battle-weary”. I noticed that there are a few small “shoots” starting off on the “old” wood. The one in the picture is right at the top of the plant. The plant is also putting up fronds from the ground. We had a relatively mild winter this year for the plants with the coldest tempreature I recorded being -4C

  1. I’ve found with both Lygodium japonicum and Lygodium circinatum that what they really don’t like is to dry out. So, I think that your luck with this may reflect the wet autumn and winter as much as the relatively mild weather. I’ve not tried either outside recently but will try again now that I have seen yours. Well done!

  2. This plant has probably been outside for 6 years or so.
    It took a long time to really establish and only got to the top of the pergola last year. I do water it, but I think they grow in very hot and dry countries, and probably does not need it. Once established they are probably very hardy, like bracken . Of course, I may just be lucky. I would offer you some spores but although it has fertile fronds, I am not sure they ever get to shed spores. Maybe the season is not long enough.

  3. I’ve seen it growing profusely in swamps in South India and it is considered an unwelcome plant in the Florida Everglades, where is has taken over in some areas. So it must like water. Having said that, I remember seeing both this and L circinatum growing in dry gullies in Kerala where it probably got flooded in the monsoons and then dried out for several months. As you say, it probably has a big root run which takes time to be established. I have it growing in pots which stand in a tray of water about 1-2 cm deep.
