Strawberry Clover Varieties Compared
Strawberry clover comes in a handful of named cultivars — Palestine, Salina, Fresa, O’Connors — mostly bred for pasture and tolerance. Here’s how they differ, and why for most home lawns the cultivar matters less than the seed quality.
- Palestine: Australia; large, productive; frost-prone
- Salina: California; salt/alkali; cold-tolerant
- Fresa: Less common in US
- O’Connors: Australian; uncommon in US
- Most common: Palestine & Salina
- For lawns: Generic certified seed is fine
- Shared: pH 5.3–8.2, salt to 3%, zones 3–9
- Pet-safe: All · Yes
Cultivars compared
| Cultivar | Origin | Notable traits | Availability |
|---|---|---|---|
| Palestine | Australia | Large, productive; frost-susceptible | Widely available (US) |
| Salina | California (from Palestine) | Salt/alkali-adapted; more cold-tolerant than Palestine | Western US suppliers |
| Fresa | Mediterranean origin | Similar tolerance profile | Less common in US |
| O’Connors | Australia | Pasture type | Uncommon in US |
All share the core strawberry-clover profile: pH 5.3–8.2, salinity to ~3%, flooding to two months, USDA zones 3–9. The cultivar tunes the edges — cold, alkali, productivity — not the fundamentals.
Palestine
Palestine was developed in Australia and is a large, productive type — the widely available high-tolerance strawberry clover in US commercial seed, bred for wet, saline, and alkaline sites. Its one notable limitation is frost: it’s susceptible to frost damage, which matters in colder zones. It gives good spring, summer, and autumn production but less in cool-climate winters. If you’re in a mild zone and want the readily available, vigorous type, Palestine is the default — but in cold-winter regions its frost sensitivity is a real consideration.
Salina
Salina was selected from Palestine and developed for California conditions, released by the California Agricultural Experiment Station. It’s named for salt tolerance and has been called the most alkali-tolerant perennial clover — the pick for genuinely saline or high-pH ground, and it’s widely used by western US suppliers serving irrigated Great Basin and intermountain agriculture. Usefully, it’s more cold-tolerant than the Palestine parent it came from, though still not as winter-hardy as common (unimproved) strawberry clover that can sit under snow cover. It also adapts well to orchard and vineyard soils and even tolerates some shade. For a salt- or alkali-heavy site in a moderately cold zone, Salina is often the smartest cultivar choice.
Fresa and O’Connors
Beyond the two main types, a couple of other cultivars turn up in the literature. Fresa is a further strawberry clover cultivar with a broadly similar tolerance profile, but it’s much less commonly available through US commercial channels. O’Connors is an Australian variety, again uncommon in the US market. For most buyers in the US, these are names you’ll see referenced more than seed you’ll actually find on the shelf — Palestine and Salina are the realiztic choices, and much generic strawberry clover seed isn’t cultivar-labeled at all.
Which cultivar to choose
For the majority of home lawns, the honest answer is that cultivar is a secondary concern: certified, pre-inoculated generic Trifolium fragiferum seed with a good germination rate performs well, and open-pollinated seed from the native range is fine for most residential applications. Where cultivar does matter is on specific challenge sites — reach for Salina if your ground is strongly saline or alkaline (and you want better cold tolerance), and Palestine if you simply want the widely available vigorous type in a mild zone where frost isn’t a concern. What matters more than the cultivar name for a lawn is confirming the label reads T. fragiferum, that the seed is certified with 80%+ germination, and that it’s inoculated (or that you add Rhizobium inoculant) — especially on the saline or alkaline soils where native bacteria may be scarce.
The verdict: strawberry clover’s named cultivars — Palestine, Salina, Fresa, O’Connors — mostly come from pasture and forage breeding, and only Palestine and Salina are realiztically available in the US. Salina is the salt-, alkali-, and cold-tuned selection; Palestine is the widely available vigorous type that’s frost-susceptible in cold zones; Fresa and O’Connors are largely reference names here. For a home lawn, don’t overthink it: certified, inoculated, correctly labeled T. fragiferum seed matters more than chasing a specific cultivar. Match Salina to genuinely saline or alkaline sites, Palestine to mild-zone general use, and generic certified seed to everything else.
Pick for your priority (fit-check)
Saline or alkaline site (and some cold): Salina — the most alkali-tolerant type, more cold-tolerant than Palestine.
Mild zone, want the vigorous, available type: Palestine — productive and widely stocked, but avoid where hard frost is common.
Ordinary home lawn on a suitable site: generic certified, inoculated T. fragiferum — cultivar is secondary; seed quality is what counts.
What not to do
Frequently asked questions
What are the main strawberry clover varieties?
The named cultivars are Palestine, Salina, Fresa, and O’Connors, mostly developed for pasture and forage. In the US, Palestine and Salina are the two you’ll realiztically encounter: Palestine is a large, productive Australian type that’s frost-susceptible, and Salina is a California selection from Palestine that’s salt- and alkali-adapted and more cold-tolerant. Fresa and O’Connors are much less common in US seed channels. Much strawberry clover sold for lawns isn’t cultivar-labeled at all, and generic certified seed works fine for most residential sites.
Is Salina or Palestine better?
It depends on your site. Salina is the better pick for strongly saline or alkaline ground — it’s been called the most alkali-tolerant perennial clover — and it’s more cold-tolerant than Palestine, so it suits moderately cold, salty sites. Palestine is a large, productive, widely available type, but it’s frost-susceptible, so it’s best in milder zones where hard frost isn’t a worry. Neither is universally “better”; match the cultivar to your conditions. For a typical lawn without extreme salt or cold, generic certified seed of either is perfectly adequate.
Does the cultivar matter for a home lawn?
Less than you might think. For most residential lawns, certified, pre-inoculated generic Trifolium fragiferum seed with a good germination rate performs well, and open-pollinated native-range seed is fine. Cultivar choice matters mainly on challenge sites — Salina for salt/alkali, Palestine for mild-zone vigour. What matters more than the cultivar name is that the label actually reads T. fragiferum, the germination rate is 80%+, and the seed is inoculated with Rhizobium (or you add it), particularly on saline or alkaline soils where native bacteria may be lacking.
Which strawberry clover is most cold-tolerant?
Common (unimproved) strawberry clover is the most winter-hardy — it can withstand snow cover. Among the named cultivars, Salina is more cold-tolerant than the Palestine parent it was selected from, though still less winter-hardy than the common type. Palestine is the most frost-susceptible of the group, so it’s the one to avoid in hard-frost regions. If you’re in a colder zone and want a named cultivar, Salina is the better bet; otherwise generic common strawberry clover handles cold well. All are rated for USDA zones 3–9.
Are all strawberry clover varieties pet-safe?
Yes. Cultivar has no bearing on toxicity — all strawberry clover is Trifolium fragiferum, a true clover that isn’t on the ASPCA’s toxic-plant list, so it’s considered non-toxic to dogs and cats across every variety. As always, the one identification caution is to confirm the seed label reads T. fragiferum, since the horse-toxic alsike clover (T. hybridum) is a different species that can resemble it as seed. That’s a species check, not a cultivar issue — any true strawberry clover cultivar is pet-safe.
Quality over cultivar
Our strawberry clover seed is certified T. fragiferum for saline, alkaline, and wet sites; on normal ground, white Dutch clover or microclover are better suited. See what it needs in the growing conditions guide, how it grows in the growth guide, how to identify it in the identification guide, or how to pick quality seed in the seed selection guide.
