A rarity for an Arisaema as it likes sun.

 
A. Consanguineum leaf.JPG

These pics were taken on 14 March 2021. I have this Arisaema for a number of years. Not sure why it has decided to be this well advanced but who is complaining.

There is a second leaf unfurling.

The shoot emerged sometime in January. One very odd thing happened to this Arisaema. I must have disgarded it somehow and in 2018 I found it growing, without initially knowing what it was, in a very large pot in 6" of water with no soil. It was about 12" tall. Everything I read about Arisaema is they need good drainage to avoid rotting and there this one was happy as Larry. I wish I had taken a photo.

This Arisaema does not mind a bit of light which is why it has done so well in our conservatory

I have had a Costatum in my front garden for many years. It has had no special treatment. It is full sun most of the day and it loves it there. It has formed a nice clump and is ready for digging up for the offsets.

See picture right. It was taken in 24 May 2020. Sorry about the picture quality. I will take better ones this year.

A. Cucullatum

I cannot find much information about this rare species. I sowed 13 seeds on 15 January 2021 . The picture right was taken on 15 May 2021. As well as the 4 obvious seedlings there is one in the top right pot. On closer inspection there do seem to be more germinating that you cannot see in the picture.

PLANTS WORLD SEEDS A. FLAVUM 5APR21.JPG
Flavum seed germinating 8 April21.JPG

Above seedling, you can just see it, germinated 8 April 21. There are 59 more seeds in the tray. It was sown on 18 December 21 outside.

Left is a seedling kept in a heated greenhouse and it germinated on 31 March 2021

Arisaema seeds have a germination suppressant on them so it does not matter when you sow them they will germinate when they are ready in the spring.

P1120663.JPG

The tray to the left has 60 seed sown on 18 December and started to germinate on 31 March 21 in a heated greenhouse. On 11 April there are 24 seedlings plus 2 others in another tray. In an outside tray shown above there were 2 germinating on 8 April slightly behind the ones in the heated greenhouse.

Unfortunately A.Flavum turned into A. Sikokianum on left. I told the supplier, direct bulbs, on 18 April 2021 with pictures. Their supplier confirmed I had the wrong one and on 20 April I received A. Flavum shown below. These things happen but how fast was that response.

Notice the very long appendage to the spadix which is brown and about 88cm long. The extension to the spathe is green and much shorter. I feel some research coming on.
