Aroids (the family Araceae)

Hans, it is to be hoped that your neighbours are not cursing you for YOUR leaky sewage system.

Hans, it is to be hoped that your neighbours are not cursing you for YOUR leaky sewage system.

Or it did occur to me that the neighbours might be angry with their builder... thinking they DID have a problem with the drains!

Embarrassing problems every which way!

  - there was extreme stench only the first day - maybe finally it came from the neighbours...

Here a pic of the leaves of those seedlings.

Arisaema thunbergii ssp. autumnale, an autumn-flowering endemic from Taiwan. Temperate but unfortunately not hardy so either for the glasshouse or pot cultivation

A nice sized spud!
My daughter trying to lift a tuber of Amorphophallus konjac.

[BULBISSIME]

  Incredible !
I suppose you already got flowers ??

[kiwi]

I would love to claim this was one of mine, but, mine are a quarter of the size and have not flowered for me yet.
This is one of many grown by a friend in greenhouse conditions. They have flowers every year and grow taller than me! To florish here in Christchurch they need that extra warmth and protection.

[Pascal B]

Oddly enough Amorphophallus konjac is one of the few species of this genus that can be planted outside and is hardy from zone 7b onwards. I know of a group planted in a garden near the arboretum in Wageningen (Netherlands) that has survived for years out in the open and has flowered.

You wouldhave to plant it deep though, mine died from frost in its 3rd year, planted in a shrubtub overwinterd in a garage

Lots of chips in that one Doug. You'd need a fish the size of a large shark to go with them.

Some Arum italicum and Arum pictum fotos taken in the local mountains yesterday. Arum italicum is a common weed but some forms  might be interesting. Sometimes black spotted plants occure - does anyone know if this is stable? They do not look ill...
First two pics show common marked plants, often leaves are plain green.

Hi Hans, there were numerous plants of Arum marmoratum with similar black-marked leaves growing around my old workplace. Casual observation over 12 years suggested the plants with these marks were stable from year to year, but I can't swear to it.

Darren we have them here as well and the one with the most spots have quite dark coloured flowers as well.

[PeterT]

Arums like those pictured are cultivated here in the UK, I have one called "Chameleon" which is stable and I know a large stand of a plant similar to the picture "italicum nice marked" which would have been planted in the 1960s /70s or earlier

[Hans A.]

Thanks Darren, Dave and Peter - I found the plants all in a very small area close together (maybe a diameter of 100m ), so I was a bit surprised about the variability - but I admit I did not pay too much attention on Arum italicum as it was (is?) a very persistent weed in my garden.
