Australian Tuberous Sundews in 2014

I collected 8 tubers of D. menziesii which started with seeds from ICPS Seeds Bank last year.


They are not so many and still mere seedlings though, I have some Australian tuberous sundews. Then finally they've got all in dormancy. So I dug the soil and collected the tubers so that I could count the numbers and compare with the numbers last year. Here are the species below.


D. collina - 10 (2013) ~ 11 (2014)
D. menziezii - 0 (2013) ~ 8 (2014)
D. ramellosa - 5 (2013) ~ 8 (2014)
D. stlonifera - 7 (2013) ~ 9 (2014)
D. whittarkeri - 7 (2013) ~ 5 (2014) 

As for D. menziezii, I sowed its seeds last year and I could gain 8 tubers after all although they are still so tiny. And I gained more tubers of most of the species this year except D. whittarkeri.

The most of the tubers increased, but the thing is that they didn't get bigger at all... I think I should have added more fertiliser in the soil. I hope their safe germination and healthy growth to the coming term.


This is  D. whittakeri in the last growing term. Should I have fed more fertiliser last year???



This is D. collina,which just germinated last winter.

This is D. ramellosa. I've been keeping this tuber sundew for 4 years that is the longest of all I have.
