What is the easiest species Tolumnia to grow?

[jason woodrue]

Hi
Any recommendations for the easiest species Tolumnia for growing in windowsill culture conditions?

BTW I live in NYC - Hot summers cold winters and E tampensis grows freaking amazing for me! I was thinking of getting a Tolumnia as a friend plant to it.

I'd be open to hybrid Tolumnia recommendations in the Easy to Grow category also, but only yellow flowered varieties with red patterns or yellow flowers with assymetric red blotches.

Easiest species tolumnia (any colour) or Easiest hybrid (yellow and red flower)?
