    Butterfly Weed (Asclepias tuberosa)

    Butterfly weed is one of the last plants to poke its head up in the spring. It will not be rushed. Butterfly weed likes to stay put. It sends down a deep tap root, which is always a sign that a plant does not wish to be moved, lifted or divided. You will probably get volunteers, which should be moved while they are young before they too send down roots.

    There isn’t a bolder blue plant out there and now Baptisia comes in dusky purples and yellows, too. But they all have deep tap roots and prefer to stay anchored in the spot they’ve been planted. Baptisia should not need any division, at all. Just enjoy.

    Hellabores ( Hellebores orientallis)

    Hosta Plants

    If you’ve ever lifted a hosta plant, you have seen the thick gnarly mass of roots they form. Hosta plants get wider and wider, without dying out in the center. They are basically slow growing ground covers, perfect for so many tough spots. If only the deer would leave them be. You can leave them be, but hosta will adjust well, if you choose to divide them.

    Nothing says Old House like a large stand of peonies. These beauties never, ever need to be divided. You can divide or move them if you really want to, but they can take a couple of years and just pout before they adjust to new surroundings. The best time to divide peonies is in the fall.

    Russian Sage is a woody perennial that is almost a shrub. It is next to impossible to lift the plant because its wispy roots run off in all directions. And Russian sage simply doesn’t adjust well with transplanting. However they will send up new plants and it is possible to dig the smaller volunteers and move them, with some success.
