I have Russel Lupines that I planted about 3 years ago and they have done nicely. But I heard they are not a long-lasting perennial. However, mine seem to be multiplying and could be getting crowded. I sure would appreciate any information out there I can get. What ph? What fertilizer? Should they be divided and if so, when?

Hello woodspirit, sheila is right, they do not need to be fed much at all, a small amount of any general feed now will be ok, but not much is needed, they do better in poor soils, and they are quite long lived, but it doesnt hurt to remove any that are poor or have small flower stems, it will give room for the younger plants to spread and grow into healthy colourful plants.

Alan.

Thanks. I have read, since I posted, that they are legumes and produce their own nitrogen. So I guess from what you say, they can be divided, but when? and what ph do they like? I have very acid soil here.

woodspirit... I envy you... Last year I bought 2 lupines, L. 'Gallery Pink' and L. 'Gallery Yellow' from a reputable garden center (not a chain!). Neither survived that I can tell. I have no clue what went wrong...

We have two big beds of lupines that pretty much take care of themselves. They reseed like crazy, move around a little, but not a lot. Tehy seem to like the road ditch. Ours are in fairly damp, heavy clay. The only thing I've ever done for them is to try and beat out some of the orchard grass and goldenrod.

Larger lupines do not like to be transplanted. They will reseed themselves prolifically - unless, of course, you really want them :) I think that is Murphy's law of gardening!
