Blue Thistle

Blue Thistle (Lactuca) - M. Plumieri is a native of the Pyrenees, where it is 4 or 5 feet high, but in our borders and in deep strong soils it is frequently as much as 8 or 9 feet high. Its foliage is beautifully varied in outline, and it should be planted in the rougher parts of the wild garden, and left to itself, as nothing seems to interfere with its rapid growth. M. alpinum is a smaller plant, and the worst weed ever got into the garden. Seed or division. Syn. Mulgedium. Some of the kinds are very difficult to get rid of once planted in good garden soil, and the place for them is the wild garden.
