The heucherella didn't do too well for me last year. I'm really hoping it comes back for me this year, because the pictures I see of other people's heucheras/tiarellas are sooo pretty.
And that's a good point about water and tulip bulbs... I'll do some research and see what combination would be good!
Springcolor, I had just planted a hellebore last spring (just one; like you said, they're expensive!), and then promptly ran over it with a hose. The top broke off and I thought that was the end of that. But yesterday, I saw new leaves! It survived! So I have great hope for yours.
