Astilbe chinensis

If you can grow false spirea in your garden, or your gardener is successful, well then, my garden hat is off as I bow. The more commonly sold A. x arendsii hybrids are indeed more popular, but they also require copious amounts of water. This is why I am focusing on A. chinensis, as Sunset explains it can tolerate a little more dryness, a sensitive subject during California's droughts.

I have a mental list of plants I would love to grow but don't feel particularly generous with water to keep them thriving, such as Phlox paniculata or Hydrangea macrophylla. Regardless, if you have a site condition where there is excess moisture in shade, then this might be a plant to consider.

Astilbes are only in the nurseries when they are in bloom, which for this species is late summer. As other summer blooming plants are fading, false spirea could be a breath of fresh air in the garden, sparking some pastel color or white. Do not be skimpy. The delicate blooms on one plant can look a little lost in the landscape. Instead, consider planting in a large mass as a statement...if you have sufficient water. Can you tell I'm jealous of East Coast gardeners with all their available rainfall?
