Deciding not to spend any more money on plants is the best thing I've ever done for my garden. It has caused me to *finally* do the designing the books all call for--masses of the same plant planted in big swaths. I get these swaths by dividing my successful plants, or digging up their babies and moving them.
My other source of garden material is my gardening friends. The ones whose gardens are so glorious that every spring they have to throw out Perfectly Good Plants because there's just too much growing in the beds. These people are my best friends right now.
And one has given me a Japanese Painted Fern, I guess one that was bothering her by growing too well. Glad I could help.
