The best vegetables to grow in Oregon’s coastal climate

Root crops

All root crops do well in our coastal climate, preferring loose, deep soil. They need high-potassium fertilizer and attention to thinning the seedlings.

Carrots: All varieties, but note the mature length; shorter varieties are better suited to heavier soil. Carrots need regular and ample water.
Beets: All beets are good. ‘Cylindra’ and ‘Forono’ are excellent 6- to 8-inch long roots giving you more beet for the space. ‘Touchstone Gold’ and ‘Boldor’ produce sweet, golden beets, ‘Chioggia’ is a nice striped Italian heirloom. The tops are wonderful in salads or sautéed. Beets require boron and our soils are generally deficient; use a fertilizer with micronutrients.
Radishes: All standard types do very well. Thin seedlings to allow room for larger radishes. ‘Specialty’ radishes such as Asian varieties may have very specific seasonal planting needs; some are only suitable for fall or early spring planting. Consult a seed catalog. Carrots and radishes must be direct-seeded. Beets can be started inside and transplanted CAREFULLY at the first or second true leaf. Turnips and rutabagas are also good possibilities.

Brassica family

All should be started inside and transplanted out. Brassica transplants don’t like to be cold; plant after last frost.

Broccoli: ‘Belstar’ is organic, all season, cold hardy and compact. It produces a large first head and many side shoots. ‘Arcadia’ and ‘Marathon’ are good winter-hardy varieties. Consider tall sprouting types too.
Cabbage: ‘Alcosa’, ‘Caraflex’, and ‘Ruby Perfection’, ‘Red Express’ and ‘Integro’ are proven varieties.
Cauliflower: ‘Snow Crown’ is early and almost ‘fool proof; ‘Cheddar’ and ‘Graffiti’ are brightly colored. Cauliflower may not mature properly if plants are too large when transplanted or if temperature extremes occur when they are small.
Kale: All grow well here! ‘Wild Garden’, ‘Red Russian’ ‘Redbor’, are varieties to consider. ‘Toscano’ is the sweetest! Ornamental kales are very edible!
Kohlrabi: ‘Kolibri’ and ‘Gigante’.
Brussels sprouts: Plant in early summer for fall harvest. Leaves need to be removed between sprouts. All cole crops must be monitored for aphids, slugs and cabbage worms (the larvae of white butterflies). If plants wilt during the day it is likely root maggots, a fly larvae.

Lettuce and greens

Lettuce: Hundreds of lettuce varieties! Look for slow-to-bolt and tip-burn resistance. Favorite varieties are ‘Winter Density’, ‘Cherokee’, ‘Coastal Star’ ‘Concept’, ‘Little Gem’, ‘Bambi’, ‘Merlot’, ‘Buttercrunch’, ‘Red Cross’, ‘Continuity’, ‘Jester’, ‘Celinet’, ‘Panisse’, ‘Oscarde’ and ‘Rouxai’. Mesclun or baby leaf blends will give you a nice variety of textures and colors.
Spinach, endive friseé and escarole grow well in cool seasons.
Chard: Does especially well; ‘Bright Lights’, ‘Ruby Red’, ‘Neon’ and ‘Golden Sunrise’.
Arugula, mustards and microgreens: Most tend to bolt quickly; direct seed and replant often for a constant supply. Many catalogs have greens mixes, good choices for home gardeners.
Asian/Italian/exotic greens: Most are easy, some may be seasonal or need special circumstances for proper growth; consult catalogs. If you are growing close to the ocean or in a windy location, a cloche will provide protection to produce tender greens.

Onions, leeks and shallots

Green and bulb onions, shallots and leeks all are best started from seed to avoid diseases. All do very well. Start seeds early late February or early March for June planting.

Green onions/scallions are specialized, will never make a bulb.
Full-size onions: ‘Expression’, ‘Candy’, ‘Sierra Blanca’, ‘Red Wing’, ‘Exhibition’, ‘Ailsa Craig’.
Shallots: ‘Conservor’ (J, B), ‘Ambition’ (B), ‘Camelot’.
Leeks: ‘Lincoln’ (N), ‘Megaton’ (J), ‘King Richard’, ‘Lancelot’.

Potatoes

All do very well in this climate; a few proven varieties follow.

Fingerlings: ‘French Fingerling’, ‘Rose Finn Apple’, ‘LaRatte’, ‘Blossom’. Standard yellow flesh: ‘Yukon Gold’, ‘Red Gold’, ‘German Butterball’, ‘Yellow Finn’.
Blue flesh: ‘Purple Majesty’, ‘All Blue’.
White flesh: ‘Purple Viking’, ‘Red LaSoda’, ‘Red Norland’, ‘Kennebec’, ‘Red Pontiac’. Seed potatoes are available at farm/garden stores in March. If it is past mid-April, try catalog vendors.

Peas

Oregon-named varieties and ‘Cascadia’ were developed at OSU to be disease-resistant. These are all bush varieties, they will stand up to wind better than tall types.

Sugar pod: ‘Oregon Sugar Pod II’, ‘Oregon Giant’, ‘Sugar Daddy’.
Snap: ‘Cascadia’, ‘Sugar Sprint’,
Shelling: ‘Oregon Trail’.

Green beans

Bean seeds need warm soil to germinate and are easy to start inside in pots. Transplant carefully outside after the last frost. Dark bean seeds germinate better in cool soil.

Bush: ‘Jade’, ‘Derby’, ‘Oregon 54’, ‘Maxibel’ (green), ‘Soleil’ and ‘Rocdor’ (yellow), ‘Jumbo’ (Italian flat).
Pole beans: These must be trellised, they don’t stand up well to wind but take less space and are more productive. Varieties to consider are: ‘Fortex’, ‘Helda’, (Italian flat).

Squash

Summer squash grows very well, two plants will improve the pollination of flowers that is required for success. Coastal favorite: ‘Sure Thing Hybrid’ and ‘Paternon’ (parthenocarpic) zucchini produce fruits even when there are no bees and no male flowers! Zucchini: ‘Gadzukes!’, ‘Cocozelle’ , ‘Fordhook’, ‘Cupcake’, ‘Gold Rush’, ‘Gold Mine’. Yellow crookneck: ‘Horn of Plenty’, ‘Summerpac’. Scallop: ‘Sunburst’, ‘Peter Pan’.
Winter squash and pumpkins: These require a long season, good pollination and some warmth to mature. Choose the shortest maturing varieties, under 90 days for coastal areas; most will do well inland. ‘Honey Bear’ acorn does well close to the ocean if it is protected. ‘Sunshine’ and ‘Sweet Meat’ are very sweet, good inland. Butternut squash is a different species and will not cross-pollinate with other winter squashes.

Cucumbers

Pickling, lemon, standard slicing and seedless types all will grow better with protection. Cucumber plants like to be warm and seeds require very warm soil to germinate. Unless it is stated that they set fruit with no pollination, common cucumbers require pollination by bees or insects. The following proven varieties, classed as parthenocarpic, require no pollination,: ‘Sweet Success’, ‘Diva’, ‘Agnes’. Greenhouse and seedless English varieties: ‘Pepinex’, ‘Socrates’ , ‘Iznik’, ‘Tasty Jade’ are all good.

Tomatoes

There are literally thousands of varieties of tomatoes. A few guidelines will help you choose what is right for your circumstances. All tomatoes will do best with protection even in the east county; choose the sunniest spot available. Cherry and grape types are likely to ripen earlier. For the cloche, choose determinate (DET) or dwarf varieties; they will stay shorter. Most tomatoes will do well in a greenhouse with good ventilation. Indeterminate (IND) tomato plants can get quite tall and should be staked or caged; large-fruited ‘heirlooms’ may not ripen in this climate. Always choose the earliest varieties. When growing tomatoes in pots, be sure the container is large enough to support a large plant. All tomatoes require good nutrition and a constant supply of water to prevent blossom-end rot.

Peppers

Must have substantial protection, sun and heat to mature. Hot peppers generally ripen better than sweet varieties. If you can provide full sun and heat, most will do well; a cloche kept closed works. Choose short-season, early maturing sweet varieties or they will not ripen quickly enough.

Perennial vegetables

Artichokes: They like our climate, need lots of space, sun, well-drained soil and must be protected with mulch during the winter. Artichokes don’t like cold wet roots and may not survive cold winters unless soil is very well drained. They are very attractive to aphids and a good place for earwigs to hide. You will need to be vigilant to keep these pests at bay. Artichoke variety ‘Imperial Star’ will produce chokes the first season.
Asparagus: Long-lived perennial, spreads outward and needs space. Very attractive to slugs, asparagus must be protected before spears emerge, use slug bait or copper strips. Asparagus can be grown from crowns available in the spring or from seed. Either way, they will take two or three years before becoming large enough to eat. You can cut them for approximately six weeks, then leave the spears to grow out and store energy for the following year’s crop. Both crops require substantial space, nutrition and water.
Jerusalem artichoke or “sunchoke” is actually a tuber that grows underground from roots of a perennial sunflower native to eastern North America. Easy to grow, plant grows 5- to 9-feet tall and can be very invasive. Grow this in a large container or space where you don’t care if it spreads. Harvest the tubers in fall. It also produces small 3-inch yellow sunflowers.

Odds, ends and slightly ‘fussy’ vegetables

Celery: Grows very well, requires high N and lots of water. ‘Tango’ is good. Protect from slugs!
Bulb fennel: ‘Orion’ and ‘Orazio’ can be started inside, are easy to grow and quick to produce nice large bulbs; no major problems.
Corn requires a long warm season, can be grown inland if you choose early varieties of 75-80 days or less. I like ‘Luscious’, an organic bicolor.
Tomatillos have similar needs as tomatoes with a big, sprawling growth habit, need lots of space.
Eggplant is difficult to grow in the maritime climate. It requires more heat than peppers; a very sunny, warm spot may work.
