'Sister Theresa' Astilbe glows with thick, cotton candy-colored plumes that sway softly in the breeze. Mounds of finely-cut, green foliage remain true throughout the season, providing a graceful backdrop for later-blooming flowers. Lovely in rock gardens and when planted in drifts. Prefers moist soil. (Astilbe arendsii)

Plant Information

About Astilbes: Easy to grow, tough and hardy, Astilbes are now a mainstay in all good perennial gardens. In fact, American gardeners are in the midst of a passionate love affair with Astilbes. Native to the far east, these beautiful plants and their hybrids have revolutionized the perennial possibilities of moist, shaded American gardens. They are companions of ferns and our favorite annuals, impatiens--one of the few flowers that make big color in full or partial shade.

The vast majority of the scores of hybrids now available are the work of one man, master hybridizer Georg Arends (Yes, that's why you keep seeing arendsii tacked onto hybrid names.) Mr. Arends, working in Ronsdorf, Germany spent decades hybridizing Sedums, Phlox, Campanulas....and his first love, Astilbes. In 1933, Arends introduced 74 different Astilbe cultivars, and there have been hundreds since.

These plume-flowered plants have ultra-handsome fern-like foliage, (usually dark glossy green) and stiff stems that always hold the elegant plumes aloft without any staking. Flower arrangers find the flower plumes are just as handsome in a vase as in a garden.

From tiny dwarfs to big draping hybrids, Astilbes are all quite easy to grow, as long as their ground does not dry out for long. They must have plenty of moisture, so choose your locations carefully.

    Comments about American Meadows Sister Theresa Astilbe:

    Plants were very healthy when received. They are struggling a bit now since my area is very hot and dry (Sunland, CA) so I planted them in a variety of shady spots in my garden. But I am unsure if the temperatures may be too extreme. Astilbe do OK in another local garden. Too much light? Too little as placed? We'll see. Astilbe are lovely plants so I hope at least one locale will be OK. It's worth trying.

      I plant these under a tree at our campsite. They did not bloom very well this year but they usually bloom in June and I just planted them this year. I am going to order more and plant them this fall. I am expecting them to do fantastic next year and have beautiful pink feathery blooms under my tree next year.

        Comments about American Meadows Sister Theresa Astilbe:

        I planted this Astilbe in a mixed-sun flower bed. It was placed toward the back, and grew beautifully, as a backgound flower. The color blended well with the mix of purples, pinks, and yellows I had chosen, and the darker green leaves set off it's beautiful pink flowers. It does take up a lot of space, as it grows quickly, so you need to make sure there is plenty of room around it to grow!!

            Q & A

            Plant With These:

            USDA Hardiness Planting Zones

            To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

            • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
            • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
