Oops, let’s try this one again


 

Jim Waddick’s experiences with certain aroids have me wondering


 

Pinellia ternata and P. pedatisecta are the bad ones here. P. ternata
spreads primarily from the little corms which form on the leaves. P.
pedatisecta spreads rapidly from its abundantly produced seed. The ripe
infructescence shatters at the slightest touch, leaving the ground littered
with the white seeds. The seedling plants look like aroids, but will leave
you wondering which one. For the first few years the gardener will probably
be more or less clueless. Eventually you will notice them coming up
everywhere. 

 

I’m beginning to wonder if I will ever be able to get rid of either of them.


 

They turn up in unexpected places here, including in the soil mixes I
prepare from garden soil. I can’t help wondering if Jim Waddick’s volunteer
Helicodiceros might not be one of these champion interlopers. Jim, are you
sure they are Helicodiceros? Have your Helicodiceros ever produced seed?
