Gardeners' Notes:

I do not know yet if this plant grows naturally in our region. I live in South Central New Brunswick , Canada. I purchased a Goatsbeard plant from a local nursery last fall (2011) and planted it at the Northwest corner of my house which is shaded most of the time so it only gets about 3-4 hours of sunlight per day. It got accidently mowed down shortly after planting but this spring came back nicely and is currently about 3 feet tall with beautiful cream coloured flowers. Does anyone know if this plant is harmful to rabbits or if rabbits will eat it? We have a real bad rabbit problem here. I currently have it fenced in.

Blooms mid to late June in my garden. Very pretty little plant.

This is one of my favorite perennial - it stays compact and lovely all growing season long - it makes a excellent border plant for the shade garden - it seem to wilt rapidly if planted in more sun. Much less underused compare to American Goatbeard. The only problem with this species is its senstivity to moisture needs when first planted - it prefers to be constant moisture for its first year. Patches will grow slowly in size - I hadn't divide one yet but it look like it take about 6 to 8 years to reach divideable size.

This is one of my rock garden favorites. It is beautiful all season long, the flowers are just an added bonus. The info says it doesn't want to be dry or in sun, but my rock garden is definitely more dry than wet, and almost full sun, and it has remained happy for 5 years. It is growing only slowly, and remains a tidy round mound of soft foliage. In the spring, surrounded by 'Lilac Wonder' Tulips it is beautiful.

More adaptable than the standard Goat's-beard. Lovely foliage; if a female plant, leave the faded flower spikes as they turn orange in autumn, adding extra interest for this plant.

This is much easier to please than the taller goatsbeard. Resembles a particularly fine-foliaged astilbe. Flower spikes do not persist when finished flowering, but foliage stays better than most astilbes.
