ARISAEMAS

I'll try to post here a seasonal progression of my Arisaema species growing in my garden.


Arisaema nepenthoides
this was the first up and the first to bloom in late winter along with Trillium, 
then the deer came to my garden for breakfast. 
The only picture I got this year was with the missing flower. 
This is a form with silver leaf patterning. So far this tuber has not had offsets or spread.
The foliage is still present and healthy in mid June
 so maybe without the flower the tuber will get really strong and divide.

Arisaema sikokianum
These are among the earliest to come up in the spring.
All those in my garden now are ones I have grown from seed from a few I purchased years ago which have met their demise one way or other.

these are in a drier spot
and seem to be diminishing-
another one there did not come up this year

Arisaema griffithii 

Coming up next are my two clumps of Arisaema griffithii. 
I certainly should have divided these.  I started with two tubers and now have about 6 in each clump. I will have to find out the best time to separate them.

Arisaema speciosum 

I've had this twice before, but the tuber either froze out or rotted out.
So I bought another one early last year ~ March 2013- planted in a new spot.
It did well last year and even survived our two extra cold spells last winter. 
So I was quite surprised to see it come up so healthy and larger this year.

Look at the amazing spadix filament how it keeps growing and looping first over the leaf, the leaf then keeps growing and lifting the filament up, but as the filament continues to grow it loops back down to the ground again and wraps around other plant foliage. 

Then it went up again and back down. 

This provides a path for  ants gnats, bugs, etc. to crawl up into the the spathe to fertilize the flowers. I hope this plant has both male and female parts this year, I haven't gently pulled it apart to check yet.

Arisaema taiwanense

I added this to my collection last year from Dan Hinkley's Windcliff plants. 
The plant from last year did really well, produced what I thought were fertile seeds since the seed pod was huge and each seed was full and lasted long into the fall-- 
but when opened up I could not find any seed. 
I bought another plant this year to increase my clump.
I'm just getting too old to wait so long anymore. The next generation will just have to divide everything up if it gets too crowded. I'm just not patient enough to wait. 
That said, if I do get seed this year, you can bet I'll be trying to germinate it and planting it.

Arisaema ringens

I've had two of these for quite a while but one did not come up this year and the remaining one is declining. 
They are probably too shaded and possibly too dry during the summer, or possibly the moles have undermined them. . 

Must be time to move it to a better place.

Arisaema utile

Added this  to my collection this year purchased from Naylor Creek I think.

Love those big leaves!

Wow, have these guys decided to spread this year!

Arisaema consanguineum

This is the first Arisaema I ever purchased, a long, long time ago at Heronswood, back in the day when you had to label your own plants.  So for a while I did not know if it was concinnum or consanguineum since I only wrote "A. con" on the tag. 

I've been growing these from seed ever since 

and watching the clumps spread on their own as well. 

They are one of the latest Arisaemas to emerge.

Arisaema tortuosum

I've planted these in two different places. In my upper moss garden they are staying very small while other things growing there are flourishing. I've tried adding compost under the moss, and fertilizing, but it is not working. Darn! I want them to grow there. They would stand out and look great. 

 In t he other spot  under the Styrax, they are growing well, but leaning way over reaching for the sun.

Arisaema candidissimum

I had two large containers of these with many offsets growing in my greenhouse that I got at Fronderosa Frolic from Marietta O'Byrne in Eugene Oregon. But by the time I decided where to plant them ( a few years later)  they did not come back the next year. 

So last year in 2013 I bought two more from another Oregon nursery that was at Sorticulture. I immediately plaanted them where I had hoped the others would grow and lo and behold they did come back this year and are producing bloom and offsets!
