    Nursery contributed plant descriptions

    Vigorous, open shrub to 10', enormous red brushes spring, like citrinus but hardy. Callistemon taxonomy being difficult, I haven't exactly figured out what this is, so 'Red Giant' will have to do. As Callistemons go, this one has about the largest leaves and flowers of anything we have yet found that is hardy for sheltered Northwest gardens. It grows large indeed, to 10' x 10' or greater, with a rather open habit and grey-green leaves. The flowers, which appear in late spring, are huge, numerous, and deep red. In the Northwest this seems to remain undamaged to about 15 °F or brief dips to lower temperatures. In climates with hotter summers it ought to be hardy to at least the single digits, and it could grow even larger.
