Did you manage to talk "yourself" into getting one, Richard ? I just can't grow tall bearded Iris, without others certain plants, to go right along with it.
That's why I order from Jung's .. I'd bought 'Dusky Challenger' to go along with roses, peonies & other perennials for a mixed border & rather than ordering 'border" Iris, i''d simply get 'tall bearded", instead.
They'd usually have a decent selection, & I could always call on the phone & just "add" to my existing order each month, & just pay extra, for postage, as the order "builds up" until delivery ends.. But, now days, everyone, is in such a hurry to buy it up, all at once, well in advance !
I think they tend to offer some nice ones, each spring & autumn & would buy just at least several each year, both spring & fall & before you know it, in ten years, there'd easily end up with 40 Iris, just from there, alone..
