Last fall I planted two types of Camassia in the rain garden, one blue and one white. I thought they would bloom together but the blues popped out in April and the whites are just now opening up.
Thank goodness for these kinds of misunderstandings. It's so much nicer to enjoy them individually.
Also filing under things-I-didn't-know, the Korean lilac smells amazing right now. I don't remember it having a very powerful fragrance last year. It's planted outside our kitchen door and walking outside right now is such a wonderful experience. I love spring!
