The Astilbe Koln or Japanese Spirea...terrific addtion to the shade garden

About The Astilbe Koln

I planted the Astilbe Koln or sometimes called Japanese Spirea in my south flower garden, which receives morning sun and afternoon shade. While I understand the concept that this perennial grows better in the shade, I can now say that the two Astilbes planted in my peninsula garden and the Astilbe planted at my ponds edge, all in full sun, are doing extremely well. All have bloomed and in fact I have left the dried plumes as focal interest.

If planting in full sun, please remember to give extra water to the plants. The leaves will actually begin to wilt and dry up if they are deprived of moisture.

The Astilbe Koln variety is a hardy clump-forming plant with lovely soft feathery spikes of cerise-pink flowers. It blooms mid season; in July and August.

In the spring of (2009) the tips froze on three of my newly planted ones (a late frost), but thankfully they recovered and grew into beautiful mini shrubs.

The Astilbe in general is late to break ground in the spring so be patient and better yet, make sure that you mark the ground with the plant tag. I am in the process of inserting plant labels for my perennials. It is common for me, from to time, to forget the whereabouts of a plant or two.

Be mindful that some Astilbe's can grow to be a mid sized perennials, almost shrub-like. Not so much in height as in width. So, read the plant tag, determine the space needed in your garden design and plant accordingly.

Great companion plants for the flower garden design: Purple Angelonia, Marigolds, Hostas, Ageratum or Ajuga groundcover.
