Types of Grass in California: The Common Lawn Grasses
Marcus GreenTurf Management Pro | 18 YearsShort answer: California grows both cool- and warm-season lawns. Cool-season tall fescue, Kentucky bluegrass, perennial ryegrass, and fine fescue suit the cool coast and north, while warm-season bermuda, zoysia, St. Augustine, buffalograss, and kikuyu win in the hot interior and use far less water. In a dry-summer state, how much water a grass needs is often the deciding factor.
California is Mediterranean and summer-dry, and it is genuinely a mixed cool-season and warm-season state. UC's framing is simple: cool-season grasses suit the cool, humid coast and north, while warm-season grasses are most competitive in the interior valleys and desert regions and need less water. This guide covers every common type and how to tell which one is already in your yard.
The types of grass that grow in California
Tall Fescue
Tall Fescue is California's default lawn grass. UC notes that most California lawns are planted with tall fescue, which holds green with less thatch than other cool-season species. It is a coarse grass that stays green through California's mild winters. It still needs regular summer water, though its deep roots make it the most drought-tolerant of the cool-season grasses, which is the central tradeoff of a cool-season lawn in a dry-summer state.
Kentucky Bluegrass
Kentucky Bluegrass is a fine-textured cool-season turf usually blended with ryegrass for a classic lawn. UC says it grows best in fall, winter, and spring when temperatures are cool and requires frequent irrigation through the summer. It knits a dense sod by rhizomes but is one of the thirstiest common choices in California heat.
Perennial Ryegrass
Perennial Ryegrass is the fast-establishing companion in cool-season blends and the standard grass for winter overseeding of dormant warm-season lawns, especially in the desert. UC lists it as well adapted to sunny or partially shady conditions that grows best in cool temperatures. It germinates quickly, which is why it anchors seed mixes and overseeding.
Fine Fescue
Fine Fescue is the shade and low-input option for the cool, humid coast and the north. Its needle-fine blades tolerate shade well and fill in shady areas where other grasses thin out. It asks for little water or fertilizer but does not take heat or heavy traffic, so it usually rides in a blend rather than standing alone.
Bermudagrass
Bermudagrass is the workhorse warm-season lawn for hot inland and Southern California. UC calls it drought tolerant and well adapted to sunny conditions, and it uses notably less water than a cool-season lawn, but it becomes dormant and loses its color in cold weather, so it browns out over winter away from the mild coast.
Zoysiagrass
Zoysiagrass is a dense, slower-growing warm-season turf for inland lawns. UC notes it requires less fertilization than bermudagrass and needs only infrequent irrigation once established. It forms a tight, weed-resisting carpet, but it is slow to fill in and goes dormant tan in winter cold.
St. Augustinegrass
St. Augustinegrass is the most shade tolerant warm season grass and a good fit for mild, frost-free coastal Southern California. UC also calls it relatively drought tolerant, but it is frost-sensitive, so it is limited to the warmer, milder parts of the state.
Buffalograss
Buffalograss is a low-water native, a warm-season grass native to the North American Plains that UC says can survive with very little fertilizer, water, and mowing. The UC-bred 'UC Verde' selection is promoted for hot, dry interior California as a drought-friendly lawn and turf alternative. It rides out drought by going tan and dormant, so a little summer water is what keeps it green.
Kikuyugrass
Kikuyugrass is California's oddity. UC classifies it as an extremely aggressive perennial weed of turf and landscapes, yet in mild coastal zones it is mowed and used as a low-input lawn. It was brought to California about a century ago for erosion control and never left, so plant it deliberately only with eyes open, because it spreads hard.

| Kikuyugrass | Warm | Coastal, aggressive spreader | Full sun, some shade | Low | Low but invasive |
How to tell which type you already have
Start with the big split: does the grass grow in clumps or spread by runners? The cool-season grasses mostly grow in bunches, though Kentucky bluegrass spreads underground instead, while the warm-season grasses spread by runners across the surface. Blade width, color, and the seed head sort the rest.
| Grass | Blade | Growth habit | Standout tell |
|---|---|---|---|
| Tall Fescue | Wide, coarse, rough edges | Bunching, no runners | Grows in clumps, not a spreading mat |
| Kentucky Bluegrass | Fine, soft | Spreads by rhizomes, dense sod | Boat-shaped blade tip; open seed-head panicle |
| Perennial Ryegrass | Fine to medium, glossy | Bunching | Shiny blade underside; fast to sprout |
| Fine Fescue | Very fine, needle-like | Bunching, some creeping | Wispy, thread-thin blades in shade |
| Bermudagrass | Fine, wiry | Runners above and below ground | Bird's-foot seed head, even in mowed lawns |
| Zoysiagrass | Fine to medium, stiff | Slow, very dense | Springy carpet feel; crunches when dry |
| St. Augustinegrass | Broad, flat, coarse | Thick surface runners | Runners you can lift and trace; planted from sod |
| Buffalograss | Fine, soft, blue-green | Sparse surface runners | Curls over as it cures; thin, open stand |
| Kikuyugrass | Coarse, light green | Aggressive thick runners | Whitish flower filaments; boardwalk-like stolons |

Which types grow in your part of California
California spans cool coast to hot desert, so the right grass changes dramatically across the state. UC's rule of thumb: cool-season grasses for the mild, humid coast and north, warm-season grasses for the hot interior where they save water.
- Coast and North Coast: Cool, humid, mild summers. Cool-season grasses dominate: tall fescue, bluegrass and rye blends, and fine fescue in shade. Kikuyu persists here. The lowest lawn water demand in the state.
- Central Valley and interior: Hot, dry summers with some winter frost. Both types grow, but warm-season grasses (bermuda, zoysia, buffalograss) are the water-smart pick; tall fescue is common but thirsty.
- Southern California: Mild and Mediterranean. A mix of tall fescue lawns and warm-season bermuda and St. Augustine, with St. Augustine suiting the milder, frost-free coast.
- Low desert (Coachella, Imperial): Extreme heat. Bermuda is the permanent lawn, temporarily overseeded with perennial ryegrass each fall for winter color. The highest lawn water demand in the state.
- Mountains: Real winter cold, so cool-season grasses dominate. Warm-season grasses go dormant below about 50 to 55F and are limited to the warmer foothills.
California grass timing that matters
California does not have one frost line or one grass calendar. Much of the coast and Southern California rarely sees a hard freeze, so the season depends on which type you grow and where:
- Cool-season grasses (tall fescue, bluegrass, rye): most growth in fall and early spring. With summer water they stay green much of the year; without it they brown in the dry-summer heat, and mountain winters push them into dormancy. Establish in fall or spring.
- Warm-season grasses (bermuda, zoysia, buffalograss): most growth in summer heat. Most brown and go dormant when average temperatures stay below about 50 to 55F, though cold-hardiness varies (zoysia holds color longest, St. Augustine least) and kikuyu can stay green in the mildest coastal spots. Establish in late spring into early summer.
- Overseeding: dormant warm-season lawns, especially desert bermuda, are overseeded with perennial ryegrass in fall for winter green.
- Pre-emergent: often a two-pass job in California, late winter to early spring for summer weeds like crabgrass, and fall for winter weeds like annual bluegrass. Mild winters mean an earlier spring application than in cold states. If you overseed with ryegrass in fall, skip the fall pre-emergent there, since it blocks the ryegrass from germinating too.
- Water is the real variable: UC data shows a desert lawn needs roughly three times the summer water a coastal lawn does, and cool-season grasses require more water than warm-season grasses.

Frequently asked questions
What is the most common grass in California?
Tall fescue. UC notes most California lawns are planted with it, since it stays green through mild winters and resists thatch better than other cool-season grasses. In the hot interior and Southern California, warm-season bermuda is the water-smart alternative.
How many types of grass grow in California?
About nine are used as California lawns: cool-season tall fescue, Kentucky bluegrass, perennial ryegrass, and fine fescue, plus warm-season bermuda, zoysia, St. Augustine, buffalograss, and kikuyugrass. The state grows both types because it spans cool coast and hot interior.
What is the best low-water grass for California?
Warm-season grasses use less water than cool-season ones, and native buffalograss is the lowest-water lawn of all. Bermuda is the durable low-water choice for hot, sunny yards. UC and California water policy actively push these over thirsty cool-season turf.
Why is my California lawn using so much water?
Because it is probably cool-season. UC data shows cool-season grasses like tall fescue need more water than warm-season grasses, and desert lawns can need roughly three times what coastal lawns do. Switching to a warm-season grass or a turf alternative is the usual fix.
Is kikuyu grass good or bad?
Mostly a weed. UC classifies kikuyugrass as an extremely aggressive perennial weed, and it is very hard to remove once established. In mild coastal California some people do mow it as a low-input lawn, but plant it only knowing it will invade beds and neighboring yards.
