Fertilize Goatsbeard?

Are there different 'sizes' of this plant? I've seen the miniature ones and they're teeny - but it seems I've bought a few that never get as tall as some others and they've all been in the same place for the same length of time. Should I fertilize them and if so, what?

TIA,
Westy

RE: Fertilize Goatsbeard?

There are different species of Aruncus (plus some hybrids) and some are much smaller than others. I believe Aruncus aethusifolius is the smallest at about 12 inches. To my knowledge it isn’t as common in cultivation as Aruncus dioicus which is the plant most often seen in garden centers. I only grow 2 - dioicus and a hybrid ‘Zweiweltenkind’ which is a hybrid of dioicus and sinensis. Dioicus is suppose to be the taller of the 2, but when in bloom both top out at about 4 feet. Out of bloom Zweiweltenkind is a lot shorter - maybe 18 inches without the flowers.

I’ve never fertilized my plants. They grow in kind of a natural area of my garden which only gets a deep cover of leaves in the fall (about 12 - 18 inches of ‘em). They gradually decompose the following year. I’ve been doing this for years and the soil in that area of the garden is magnificent! The plants seem to love it.
