If you don't have Saffron, get her. If you don't have Dendrobium, get her. Scotchbroom is quite decent as well, but I would take Saffron and Dendro first.
For myself I got three new units: Ionocidium, Lagurus and Cattleya. I'd been wanting Cattleya forever, but kept putting her off since there were better choices; even tonight I had to talk myself out of getting Dogwood instead. A new Apple was my 5*.
