Plant identity and growing facts

Reference: Primo ® 'Pistachio Ambrosia' Coral Bells Heuchera hybrid — Proven Winners, checked 2026-10-31. Dimensions describe an established plant rather than the size of a pot offered for sale.

Does it fit your growing space?

The published exposure is Part Shade to Shade, with a mature height of 10 - 12 Inches and spread of 28 - 32 Inches. Its published width is substantially greater than its height, so budget for lateral spread rather than treating it as a narrow upright accent. Check the light at the actual planting spot, including shade cast by taller plants as they grow.

A spacing sketch for Primo® 'Pistachio Ambrosia'

Using the upper published mature width of 32 inches, 3 plants would occupy approximately 96 inches of a ten-foot run if their mature canopies just met. This is a scale illustration, not a planting prescription. It reserves the full mature width for each plant; paths, access and the breeder’s planting-distance recommendation may require more room. A mixed border needs space for its other plants as well.

Water, winter conditions and maintenance

The breeder’s water category is Average. Use it to compare this selection with neighboring plants; it is not a fixed watering interval. Check the root-zone moisture, drainage and weather when deciding whether to water. Its listed hardiness range is 4a–9b. Hardiness is a winter-cold reference, not a guarantee of performance in every soil or summer climate.

“Thrives in part shade but will grow in full shade. Plant in humus-rich, well-drained soil. Trim back tattered…”

This short opening excerpt is from the breeder’s maintenance notes. Read the complete instructions for this exact selection before using fertilizer or changing a pruning routine.

Using Primo® 'Pistachio Ambrosia' in a landscape

The breeder describes its habit as mounded. Its yellow foliage is part of its visual role, while the recorded seasonal interest is mid summer. Compare the mature outline with the available bed width, sightlines and access around the planting. Repeat a selection for continuity only after checking that the location meets its light and water requirements.
