#1960 - Arum italicum - Italian Arum
AKA Italian Lords-and-Ladies, Arisarum italicum, and Late Cuckoo-pint. Native to the Med, and naturalized in Great Britain, the Netherlands, Crimea, Caucasus, Canary Islands, Madeira, Azores, Argentina, and scattered locations in America, and a weed in SE Australia and Tasmania. A very common roadside plant in New Zealand, despite all that.

Ignore the big green strap-like leaves above - the actual leaves are the dark green ones with pale veins. The flowers are very typical Arums - an inflorescence called a spadix, protected by a leaf-like hood, although the actual flowers are hidden down in the depths of the hood.
These plants are one of the species that can generate their own heat - if enclosed, the spadix can reach over 51° Centigrade - over 35°C more than the surrounding air. They manage this by rapid consumption of starch in cyanide insensitive respiration - biochemically different from the respiration normally found in plants. The heat vaporizes odour components - usually foul smelling - and attract gnats and other small flies that become trapped in the lower half of the bloom, by a ring of hairs halfway down the spadix. Below that is the ring of male flowers, and below that a ring of female flowers. The insects will quite possibly die before the hairs wither to release them, but they’ll have done the job the plant wanted them for.

Monday I worked in the Med garden, then did a bit of strimming and finished the day harvesting kumquats for Sarah-Jane to make marmalade. Tuesday, it had rained over night, Michele and Karim decided it was a perfect day to clean the atelier.
I helped them a bit, and I also worked with Kevin and Sébastien (they’ve been friends since they were kids) weeding around the lavender along the terrace walls (les restanques). There is a lot of clay in the soil here. I’ve never worked in clay before because both Kew and Chelsea had very free-draining soil. Clay is much colder, and very slippery. Sébastien and I took a lot of cuttings of the lavender and put these in sand. I’m comparing how these do in pure sand to how the ones in half potting soil and half perlite (I took a few weeks ago) start rooting.
Wednesday Sébastien and I continued weeding the lavender beds along les restanque; it was a grey, damp day. We finally finished clearing the rows of lavender of weeds on Friday morning.
Thursday afternoon we took a break from the lavender beds and finished taking out the dead parts of an old Punica granatum at the bottom of the property. M. wanted it completely removed, Mme. prefers to keep things if there is a chance they might come back (much like Elizabeth in London). So I suggested we see if the young growth comes back vigorously over the next year or two... We shall see. This was also my first opportunity to learn how to use a chainsaw (une tronçonneuse). We found ants had nested in the dead trunks, so we left the rest for them.
This week I was tasked with overseeing the construction of the new part of the garden. I get to try to keep big, burly French landscapers in check. It turns out I know someone who works for this company, Florian. He attended London College of Garden Design with me in 2012/13. Friday afternoon I oversaw the planting of three Prunus mahaleb, key focal points around a new patio area.
I drove Sarah Jane to Nice Côte d'Azur Airport Friday night. I took surface streets which go along the coast. It was fast, only about ten kilometres, little traffic and it avoided the toll route, the A8. It is very quiet without her here. She’s in London visiting family and friends for a month.
I have been in Antibes one month! To commemorate this life-changing move, I’ve decided I need to make a huge effort to learn French. To encourage me to learn something new everyday, I’ll be posting ten new words a week, words that have come up during the week.

This weekend it rained incessantly. I worked on Arabella’s database and I wrote my Christmas letter, which will be emailed this year because I haven’t had time to find a printer in town.
Saturday night I enjoyed a Zoom Christmas with relatives in California, Illinois and Wisconsin. It was really nice to see and chat with them. Sunday I continued working on Arabella’s database. I received my numéro fiscal Sunday morning, so finally things are moving along. It finally stopped raining around 17.00.
It was announced Sunday evening that all flights between the UK and much of western Europe will be cancelled from midnight tonight. A strain of CoVid-19 that is 70% more infectious has been identified in London and the south east of England. This may scupper my New Year’s Eve plans with Denis and André who are supposed to be returning to Antibes from London after Christmas.
