'Lakeside Elfin Fire' - I've found this one to be a fast grower for one with a white leaf centre, but not fast enough to make a good border; so I dug all the plants from the "border" and lumped them together last spring.
'Lakeside Zinger', mid July. Another which quickly grows into a dense mound.
'Lonesome Dove', late June. I've found this one to be an exceptionally slow grower.
'Peanut' is not a fast grower. This one around July 21.
'Popo' in mid July. I've had this a couple of years and quite like it.
more tomorrow. Want to watch some TV.
