I take a look at the colourful and intricate Fittonia, aka the nerve plant, and answer a question about notching Ficus plants.

Check the notes below as you listen…
This plant has gorgeously intricate foliage, but it has a reputation of being a bit of a diva “fainting” - collapsing suddenly - whenever it gets too dry.
The genus Fittonia was named by the Belgian botanist Eugène Coemans in 1865.
Coemans named the Fittonias in honour of Elizabeth and Sarah Fitton, who were Irish sisters and authors of a well-known book called Conservations On Botany which came out in 1817: this book was an example of didactic dialogue - teaching botany through a conversation between a mother and son.
The Fittons also had the genus Afrofittonia named after them - there is only one species in the genus, Afrofittonia sylvestris.
The Fittonia and Afrofittonia genera both belong to the Acanthaceae (acanthus family) - other houseplants from this family include Persian shield (Strobilanthes dyerianus), the monkey plant (Ruellia makoyana), and the polka dot plant/freckleface (Hypoestes phyllostacha) from Madagascar.
There are two species in the genus Fittonia - F. albivenis and F. gigantea - although you may have seen lots of other, now-superseded scientific names being used. Most of the plants for sale as houseplants come under either F. albivenis Aryroneura Group or Verschaffeltii Group (Red and pink-veined).
The plant hunter and nursery owner William Bull of Chelsea, London seems to have been the first to offer this plant.
Within a year of the genus gaining the name Fittonia, there were reports in British papers of plant shows where growers were entering their Fittonia plants into the new plant categories.
In its home in South America, Fittonia grows as a creeping herb, terrestrial rather than epiphytic. It has various traditional medicinal uses including as a headache treatment, as a way of making dogs better at hunting, and for treating liver problems. Don’t try this at home though.
The ASPCA lists Fittonia as non-toxic to cats and dogs.
There are LOADS of Fittonias to choose from - here are a few of the ones I find notable:
‘Skeleton’ (pictured above) with lime green leaves and pink venation
‘Titanic’ a smallish Fittonia with white veins
‘Daisy’ has grey-green leaves, white veins and some cream variegation at the leaf edges
‘Frankie’ has pink veins and ruffled veins
‘Fortissimo’ is one of my favourites with bold pink venation and dark green leaves
This plant needs to be kept moist - it will ‘faint’ ie wilt dramatically if left to dry out too much. If your plant wilts, submerge the whole pot into a bucket of room temperature water so it can quickly get back on track. Drain, then remove to a spot where it can recover - pop a clear plastic bag over the plant and pot for a few days if it’s looking in a really bad way.
The way to avoid this problem is keeping it in a terrarium. It can cope with lowish light levels (but not your darkest corner) - remember plants in terrariums should be kept out of sun as the glass acts like a magnifying glass.
You can also keep the soil moist by placing the plant in a self-watering pot or using a wick watering system. You can also add vermiculite when repotting to make sure the substrate is moisture retentive.
Th minimum temperature this plant can cope with is around 60F/15.5C.
You will sometimes find this plant in aquarium shops - although it likes moisture it is not suitable for keeping submerged in the longer term.
This is a creeping plant so if it starts getting ‘leggy’ move it to a slightly brighter spot and trim it back. The cuttings root easily to make new plants - a good idea to keep as backups in case your main plant “faints” and cannot be brought back!
Question of the week
Alexander wanted to find out more about notching Ficus species - a way of making plants more busy by encouraging them to branch without having to prune them. Nothing simply involves making a cut with a sharp knife just above a node (the point where the leaf stalk (petiole) joins the main trunk. Use a sharp, sterilised blade and cut around a quarter of the way into the trunk. This redirects the plant hormone auxin from the growing tip of the plant right at the top, and redirects it to the side shoots, which should respond by starting to bud then grow. Spring is a good time to give this a try. You can start gradually and notch a single node, then try more: every plant responds slightly differently so it’s worth proceeding carefully.
