Growing Tiarella

Sugar and Spice Tiarella


Excellent, easy-to-grow hardy perennials with attractive leaves and spikes of starry flowers. Grow as a groundcover, in woodland gardens, or use to brighten up shaded spots. Also good in pots or mixed containers. Often evergreen, even in cold climates. Hardy in zones 3 to 8. Plant outdoors after the last spring frost. Amend the soil with compost or other organic matter and plant so the roots are just slightly deeper than in the pot. 


For part to full shade in moist, well-drained soil. Prefers soils with good organic matter content and benefits from mulching. Faded flower stems can be removed.

Use low rates of Algoflash Flowering Plant 4-6-7 Liquid Fertilizer (51087), Neptune Fish & Seaweed Fertilizer 2-3-1 (51221), or Osmocote 14-14-14 (51173).

Alternative Products

Other good flowering perennials for shade include Astilbe, Heucherella, and Heuchera.

Complimentary Products

Use Black Gold Earthworm Castings (54307) or Chickity Doo Doo 5-3-2.5 (74559) to amend soil when planting.

Tiarella Facts

Not seriously affected by insects or pests. Root weevils are occasionally a problem. Plants do not overwinter well in soils prone to wetness in winter. Tiarella is usually not eaten by deer. Garden varieties of Tiarella were developed from North American native species, and recent breeding has expanded the color range of leaves.
