Candytuft (Iberis sempervirens) comes in over a dozen distinct varieties, with white-flowering cultivars like ‘Snowflake’ and ‘Purity’ popular for their long bloom times, and newer pink and purple options adding rare color to this low-growing evergreen perennial.
Walk through a spring garden center and the white mounds stop you cold. That’s candytuft, a woody sub-shrub that keeps its green through winter and erupts in flower clusters come spring. But not all varieties behave the same way. Some bloom once and stop. Others rebloom if sheared. A few stay tiny — perfect for containers — while the spreaders can top two feet across. The variety you choose depends on where you’re planting and how much work you want the plant to do.
How Candytuft Varieties Differ From Each Other
The biggest differences come down to mature height and spread, bloom timing, and flower color. Most varieties produce pure white flowers, but the newer pink and purple cultivars give you options if white doesn’t fit your scheme. Bloom season ranges from a single spring flush to repeat cycles that stretch into fall.
| Cultivar | Bloom Color | Height / Spread |
|---|---|---|
| ‘Snowflake’ | Large white clusters | 8–10 in / 12–24 in |
| ‘Purity’ | Nearly pure white | 6–8 in / 12–35 in |
| ‘Little Gem’ | White | 6–8 in / 12–23 in |
| ‘Snowcushion’ | Brilliant white | 5–6 in / 12–23 in |
| ‘Whiteout’ | Delicate white | 2–3 in / 3–5 in |
| ‘Masterpiece’ | White with pink centers | 10–12 in / 12–35 in |
| ‘Tahoe’ | Pure white | 8–10 in / 12–23 in |
| ‘Alexander White’ | White with green tint center | 8–10 in / 12–23 in |
| ‘Pink Ice’ | Pink | 6–10 in / 12–24 in |
| ‘Absolutely Amethyst’ | Purple with yellow stamens | 8–12 in / 12–24 in |
Which White-Flowering Variety Suits Your Space?
White-flowering candytuft dominates the market, and the differences between cultivars matter most for spacing and bloom duration. If you want the classic look that keeps flowering across the whole season, one or two varieties stand apart.
‘Snowflake’ is a standard for good reason — the large white flower clusters are showy and the plant’s uniform habit makes it reliable for edging and rock gardens. Its spring bloom is concentrated but dense, and newer selections offer more consistent growth. ‘Purity’ works better if you want rebloom: shearing it back after the first flush can produce two to three additional bloom cycles through summer. It also spreads wide — up to 35 inches — so it fills ground faster than most. For tight spots, ‘Little Gem’ stays compact at 6 to 8 inches tall and works well in containers. The smallest option is ‘Whiteout’, hitting only 2 to 3 inches with a spread under 6 inches — a true miniature for fairy gardens.
All white varieties need full sun and well-drained soil. These plants rot fast in standing water.
Pink and Purple Varieties — Do They Perform as Well?
Pink and purple candytuft arrived more recently, and their bloom performance matches the white standards in most conditions. ‘Pink Ice’ was the first pink cultivar on the market and produces soft pink flowers that hold their color through the bloom window. ‘Absolutely Amethyst’ offers purple flowers with yellow stamens, creating a striking two-tone effect. It blooms from late spring into early summer. ‘First Flush Lavender’ stretches its light purple bloom from early spring into fall — one of the longer bloom windows of any candytuft. These colored varieties need the same full sun and quick-draining soil as the whites, and they spread at similar rates. The purple forms especially stand out when planted alongside yellow spring bulbs.
Bloom Time and Rebloom Potential by Variety
Not every candytuft blooms once and calls it done. Some varieties naturally repeat, and others will rebloom if you cut them back after the first wave. Here’s how the different cultivars compare on bloom scheduling:
| Cultivar | Primary Bloom Period | Rebloom Potential |
|---|---|---|
| ‘Snowflake’ | Mid–late spring | Single flush |
| ‘Purity’ | Mid-spring–early summer | Shearing gives 2–3 reblooms |
| ‘Masterpiece’ | Mid-spring–early fall | Multiple natural seasons |
| ‘Autumn Beauty’ | Spring + fall | Second bloom in fall |
| ‘Christmas Snow’ | Spring + fall | Flowers twice |
| ‘Tahoe’ | March–June | Single flush |
| ‘First Flush Lavender’ | Early spring–fall | Extended natural season |
‘Masterpiece’ and ‘First Flush Lavender’ offer the longest natural bloom windows without needing pruning. ‘Purity’ takes a bit more work but gives the biggest rebloom return for the effort — shearing by one-third to one-half after the first flowers fade is the trigger. The single-flush varieties like ‘Snowflake’ and ‘Tahoe’ still earn their keep by providing the densest early-spring display of any candytuft.
Plant Candytuft Correctly to Avoid Common Failures
Most candytuft problems start in the ground. The plant demands full sun — less than six hours of direct light reduces bloom count noticeably. It needs well-drained soil, preferably alkaline to neutral pH, and it will not survive wet clay. When planting, set the crown at the same depth it grew in the nursery pot — deeper and the stem rots. Space plants 16 to 20 inches apart for most varieties, or wider for the big spreaders like ‘Masterpiece’ and ‘Purity’. Water moderately after planting, then only during extended dry spells once established.
One maintenance step makes the difference between a one-week display and a month of color: shear the faded flower heads back by one-third to one-half immediately after the first bloom finishes. This encourages a second flush and keeps the plant looking tidy rather than leggy.
Final Candytuft Selection by Use Case
The right variety depends entirely on where you’re planting and what you expect from it. For edging a sunny path, ‘Snowflake’ or ‘Tahoe’ gives you reliable uniform mounds that won’t overrun the border. For a rock garden or alpine setup where you want something tiny, ‘Whiteout’ or ‘Snowcushion’ fits the scale. If you want the longest possible bloom season with the least labor, ‘Masterpiece’ or ‘First Flush Lavender’ naturally flowers across multiple seasons. For containers, ‘Little Gem’ stays contained and fills a pot without spilling. And if bright white feels limiting, ‘Absolutely Amethyst’ and ‘Pink Ice’ add real color variation without sacrificing any of the plant’s hardiness across zones 3 through 9.
