Grow thrift in full sun and lean, gritty soil, and keep the crown dry. Sea thrift and sea pink are the same plant.
Give it full sun, lean grit, and keep the crown dry
| Factor | Recommended | Avoid |
|---|---|---|
| Light | Full sun. In a hot, humid summer, light afternoon shade is fine | Year-round shade that keeps flowering weak |
| Soil | Lean sand, gravel, or grit that sheds water fast | Rich compost, fertilizer, or a clay hole that stays wet |
| Water | Water to establish, then wait until the mix is dry | Keeping the crown wet, especially in a cool, wet fall |
| Salt and drought | Salt spray and missed waterings once rooted | Treating a new plant as drought-proof in week one |
Give it full sun and soil that stays lean and fast-draining. [1] Rich or wet ground rots the center of the tuft, so skip compost and fertilizer. [2] Match the kind on Types of Thrift before you pick the bed. sea thrift is the usual coastal cushion.
- Plant in full sun so the tuft stays tight and the heads stay on thin stems.
- Use sand, gravel, or grit. Do not feed. Extra fertility makes the leaves flop and the center open.
- Water to settle a new plant, then wait until the mix is dry. Do not keep the crown wet.
- Cut spent flower stems to get a later flush. [3]
How often should I water thrift?
Water to establish, then wait until the mix is dry. Do not keep the crown wet. Established plants need water only in a long dry spell.
Does thrift need full sun?
Yes. Full sun keeps the tuft tight. In a hot, humid summer, light afternoon shade is fine.
Can thrift take salt spray?
Yes. Sea thrift evolved on coastal cliffs. Salt spray is not the problem. Wet, rich soil is.
Use a draining pot or trough if the ground stays wet
A pot with a drainage hole, or a trough, is the workaround when the bed stays wet. Use a gritty, low-fertility mix. Give the taproot depth — a shallow saucer is too shallow. Water, then empty the saucer. The open grit bed is the lasting home if it drains.
Can I grow thrift in a pot?
Yes. Use a pot with a hole and a gritty mix. Give the taproot depth. Empty the saucer after you water. The open bed is the better long-term home if it drains.
Set the crown slightly above the soil, and space plants so they can mound
Plant in spring, or in early fall while the ground is still warm. The nursery pot is the usual start. Set the crown — where the leaves meet the roots — slightly above the soil so water runs off the tuft.
- Dig into grit that already drains. Do not backfill with compost.
- Set the crown slightly above the soil. Do not bury the base of the leaves. [4]
- Space 6 to 12 inches apart so the mounds can meet without stacking wet foliage.
- Water once to settle. Then wait until the mix is dry. Dress the surface with gravel, not bark, against the crown.
How deep do I plant thrift?
Set the crown slightly above the soil. Do not bury the base of the leaves. Space 6 to 12 inches apart.
When should I plant thrift?
In spring, or in early fall while the ground is still warm. Avoid planting into a wet clay hole.
Divide a woody center, and replant only the healthy outer sections
- Every few years, when the center is woody or thin, lift the clump in early spring or early fall.
- Cut or pull it into sections that each have green leaves and roots. Discard the dead woody center.
- Replant the healthy outer sections at once, crown slightly above the soil, in the same lean grit. Water to settle, then wait until dry.
How do you divide thrift?
Lift the clump in early spring or early fall. Keep the green outer sections with roots. Discard the woody center. Replant at once with the crown slightly above the soil.
Not moss phlox — and not sea lavender
Thrift is not moss phlox. Moss phlox is How to Grow Phlox — a spreading sheet of phlox often sold as thrift in the South. Thrift is a grass-like tuft with poms on naked stems.
Sea lavender and statice are How to Grow Statice — airy branched sprays in the same family, not a pom on a thin stem. The Latin name comes from an old word for a cluster-headed dianthus; pinks are How to Grow Dianthus, a different cushion. Splendens is still this genus.
Is thrift the same as moss phlox?
No. Moss phlox is a spreading phlox sheet. Thrift is a grass-like tuft with round heads on naked stems.
Is sea lavender the same as thrift?
No. Sea lavender is Limonium, with branched sprays. Thrift is Armeria, with a pom on a naked stem.
Is thrift a dianthus?
No. The Latin name comes from an old word for a cluster-headed dianthus. Pinks are Dianthus. Thrift is Armeria.
Site the tuft in sun and grit, keep the crown dry, and set new plants slightly high. Rich, wet soil is what rots the center.
FAQ
Do I cut thrift back in fall?
No. The leaves are evergreen. Leave the tuft in place. Cut spent flower stems only. Cutting the tuft to the ground cuts next spring's bloom.
Can I grow thrift from seed?
Yes, from a species plant. Surface-sow on grit. Bloom often waits until the second year. Buy a nursery pot if you want flowers this season. Named kinds may not come true from seed.
Is thrift safe if eaten?
Do not eat it. Keep pets from chewing the leaves. It is an ornamental, not a salad crop.
Is lady's pincushion the same plant?
Some lists use lady's pincushion for thrift. Shop pincushion flower is usually Scabiosa, a different plant with a button head on a branched stem.
