Astilbe - Amethyst

Astilbe plants grow in shade, but flowers are more productive in an area where gentle morning or dappled sun can reach them for about an hour or two. Astilbe flowers also need correct soil and moisture to flourish. Astilbes prefer rich, organic type soil. Organic material such as compost enriches the soil and adds drainage. If your shady areas have poor, lean or rocky soil, work in some compost a few weeks before putting your plants in the ground. Amend the soil 8 to 12 inches (20-30 cm.) deep so that the roots of astilbe flowers have plenty of room to develop. Place the astilbe plants into the soil, keeping the crown at the same level as the top of the soil. Water well when planting and keep the soil consistently moist.
 
Astilbe 'Amethyst' typically blooms from late spring into mid-summer, with its feathery, lilac-pink plumes appearing from around May to July, depending on your specific climate and growing conditions, adding vibrant color to shady spots.
