Puzzles

[Anthony Darby]

I grew it in the school's wild garden in the 1980s. I wonder if the seeds remain dormant until the ground is ploughed or disturbed again? Corn marigolds are like that. A new road lay out was built to the east of Stirling (near Cowie) and one year a ramp-shaped spoil heap running through a field was just nothing but corn marigolds. They hadn't been there the previous year and haven't been there since.

Probably Anthony.

Chichorium has appeared on a verge near my house where a gas pipe was put in over the winter. It must be the same

I don't think this will puzzle you for very long.

Of course it won't, Paddy... even I know that's a leaf........

Paddy

Genus yes (my favorite), species no...

[Diane Clement]

If Pascal doesn't know, then that's worrying,     but I'll have a try at Arisaema consanguineum

[Pascal B]

It could be formosanum or consanguineum. The Chinese clone of consanguineum that has been selected by Ellen Hornig as "The Perfect Wave" and its descendants selected by Seneca Hills generally have broader leaflets, the variegated forms of formosanum usually have narrower leaflets and the plant Paddy shows can also be BSWJ3528 or one of its descendants.
If it is ex. Chen Yi it will be consanguineum but based on leaves only I can't tell.
So no, sorry Diane but nobody is perfect.....

Here's an example.

[Pascal B]

Given that silver centered consanguineum is more widely cultivated than silver centered formosanum (known as "bicolorifolium") the guess of Diane probably was right but "The Perfect Wave" has mostly been propagated through seeds and although the descendants generally have some silver line in the leaves, the offspring is quite diverse. The Perfect Wave was one of the best silver centered forms that were imported from China though.

[Paddy Tobin]

I knew it wouldn't puzzle you for long. I have it as A. consanguineum 'Silver Centre' and find it not the best to increase in the garden and the foliage far more interesting than the flower.

That goes for most of this section Paddy. Although I collect and study Arisaema, most flowers of this section with the umbrella type leaves (section Sinarisaema) are rather boring. Often in green or greenish purple flowers, they become interesting again once the fruits start to get red.

Nobody knows, nobody dares or nobody worries. . .

Anyway, here are more: The plant is far, far away from home!

[Brian Ellis]

Is it a Wollemi pine?

Is it a Wollemi pine?

My guess too.
