I grew if for several years a few years ago. It did really, really well in halfway decent (or better) soil in full sun. Orange is my favorite color (and bloom color) so I really like this plant. It's very easy from seed as well.

Why did I stop growing it? Well, the ripening seed heads are pretty sharp and I got poked and scratched by them just once too often.

Otherwise it's really just a great plant and the blooms really DO look like lion's ears.

Take care,
Grant
