How To Grow A Foam Flower and Care
Soil and Water Needs
Tiarella, also known as foamflower, is easy to care for and loves shade. It does well in soil that’s rich in humus and stays moist but drains well. The ideal soil pH is between 6.2 and 6.5.
Once it’s established, the foamflower can handle some drought. But, it grows best with soil that’s consistently moist.
Tiarella grows in USDA Zones 3-8 and prefers temperatures between 40-60°F. High heat or cold can harm it, causing stunted growth and wilted flowers.
While foamflower care doesn’t need fertilizer, adding compost or leaf mulch yearly helps keep the soil rich.
To keep your foamflower looking great, remove dead flowers and foliage in spring. With the right foamflower soil and moisture, these plants will bloom beautifully for a long time.
“Tiarellas can remain undivided for years in the garden without losing vigor, highlighting their low maintenance nature and long-lasting appeal.”
Foamflower Varieties and Propagation
Foamflower, also known as Tiarella, is a fascinating plant with many varieties. It has different leaf shapes, colors, and growth habits. This makes it perfect for various garden settings.
Propagating Foamflower
Propagating foamflower is easy. You can divide it in late fall to grow more plants or share with others. Just dig up the clumps, separate the roots, and replant them 12 inches apart.
You can also grow foamflower from seeds. But, it takes longer as seedlings grow slowly and bloom in the second year. Start seeds indoors 2 months before the last frost. Then, move the seedlings outside when it’s safe.
| Foamflower Variety | Growth Habit | Leaf Shape | Bloom Time |
|---|---|---|---|
| Tiarella cordifolia | Clumping | Heart-shaped | Spring-Summer |
| Tiarella wherryi | Trailing/Spreading | Lobed | Spring-Summer |
| Tiarella ‘Oakleaf’ | Clumping | Oak-like | Spring-Summer |
| Tiarella ‘Brandywine’ | Clumping | Maple-like | Spring-Summer |
