Six Great Easy-to-Grow Herbs for Your Colorado Garden

Herbs love Colorado, and there are plenty of good reasons why more people should be growing them here.  If we meet their basic needs, dozens of different herbs can thrive in Colorado and pay us back with wonderful flavors that enhance our meals and make our world smell sweet and lovely.  And if we’re willing to bend “the rules,” herbs are a great way to treat our pollinators to a little something extra.

Herbs won’t have the biggest, flashiest flowers in the garden.  In fact, herb experts tell us to cut off the flowers as they appear.  That will concentrate all of the plant’s energy into the oils that give the leaves their flavor and aroma.  But as a beekeeper, I leave the flowers on the plants until they begin to fade.  My honey bees love the sweet nectar that a lot of herb plants produce.  Flowering herbs are a treat for many native bees and other pollinators, too.

Either way, growing herbs in pots or in beds in your Colorado garden is easier than you might think.  Tagawa Gardens carries herbs year ‘round, but the variety of choices is at its peak as summer begins.  If you’ve never tried, now is the time to add herbs to your garden.

Basil plants at Tagawa Gardens in Denver, Colorado

It’s all about the basil

Rob Proctor's Basil plants at Tagawa Gardens in Denver, ColoradoWhenever I teach an herb class, I start by asking which plant wins the herb popularity contest.  Basil always wins.  Tagawa’s begins each season with more than twenty different kinds of basil.  The traditional “Sweet” or “Italian” basils have a loyal following among the culinary crowd.  But there are plenty more to choose from, including the spicier “Thai” basils.  They all require the same basic growing conditions:  bright sun, a rich, but well-drained soil.

My personal favorite is “African Blue Bush” basil.  For the record, I’m no gourmet cook.  (I’m barely a cook at all, truth be told.  Rumor has it I have a five-ingredient limit.)  Still, I find that African Blue Bush has plenty of flavor for cooking or for those lovely Caprese salads…. fresh tomato, olive oil, a little balsamic vinegar, fresh mozzarella and basil.

I grow African Blue Bush because the plants are big…. really big!  (Hence the term “bush.”)  When I let them flower, there are lots of lovely curving spikes of tiny lavender flowers that the bees can’t resist.  I harvest the younger leaves to use uncooked, and I eat the flowers, too.  They’re full of that splendid flavor that draws us to basil in the first place.

Give it room to grow and plenty of sunlight.  African Blue Bush will not disappoint.

Chive plants at Tagawa Gardens in Denver, Colorado

They’re cute.  They’re pretty.  They’re purplish pink!

If you have any doubts about your ability to grow herbs in your Colorado garden, at least try a pot of chives.  They grow easily from seed or from small plants, which Tagawa’s carries year ‘round.   Fresh chives can go a long way to dress up potatoes served in dozens of different ways.  But they’re also great at adding a hint of fresh-onion flavor to a lot of other dishes.

Chives grown in clumps in veggie or flower beds are charming.  Just be careful about letting them self-sow.  They’ll routinely run from one part of your garden to another.   If you pick and choose where you let them go and pluck out the excess, that’s fine.  But too many “volunteers” isn’t a good thing.  I have an area where I can let them spread as they please (mostly…).  I live and let live with a lot of them because my own honey bees and tiny native bees can’t resist the nectar in the little ball-shaped blossoms.

A little parsley, for flavor or garnish

Parsley and chives have a few things in common.  They’re super easy to grow from seed or small plants.    But if you turn your back, they’re likely to spread.

Curl leaf” is the parsley most often used as a garnish. (I can see and taste those deviled eggs now ‘cause they fall within my five-ingredient limit…)  Curl leaf parsley is pretty enough to grow for decoration even if it didn’t have such a fresh, bright taste.  “Flat leaf” or “Italian” parsley is primarily for cooking.  Both are low-maintenance and simple to grow.  But like chives, if you grow them in beds and don’t remove the flowers, they will re-seed easily.

For what it’s worth, there’s a beautiful caterpillar called a “parsleyworm” that loves to feed on parsley.  It’s one of the prettiest caterpillars I’ve seen, with stripes of green, black and yellow.  Give it all the parsley it wants!  It’s on its way to becoming a swallowtail butterfly, but it needs to eat a lot to get there.  Why not plant two pots or extra clumps of parsley so there’s enough to share?

Rosemary herb plants at Tagawa Gardens in Denver, Colorado

Some perennial herbs?

Rosemary is almost as popular as basil.  It’s extremely easy to grow from small plants in a sunny place on your deck or patio.  Rosemary is a bit shrub-like, with woody stems.  It appreciates soil that contains some grit like cactus mix to give it good drainage.  Rosemary does not want to sit in wet soil!

Tagawa Gardens carries two varieties of rosemary that may survive winters in the ground outdoors.  Lina is one of the incredibly gardening-saavy ladies in our Perennials Department.  She grows “Arp” rosemary on a fairly dry hillside in her garden.  She says it will usually survive for about five years, until an especially cold winter takes it out.   “Madeline Hill” may also stand up to winter here for at least a few if temps don’t drop too low.

I grow rosemary outdoors in a large clay pot.  It thrives during the summer and produces deliciously-fragrant stems of soft needles.  I leave the tiny blue flowers on for the bees.

But it doesn’t work to take my rosemary inside for the winter and try to convince it that it’s a houseplant. Instead, I leave it in a bright, enclosed but unheated back porch. It prefers the cold there to my warm, dry indoor air.  As long as I don’t forget to water it, it’s taken temperatures in the 20’s and never had issues.  Each spring, I give it a little trim and back outside it goes.  After a few years, it gets woody at the base and isn’t as pretty or as productive so I replace it.

Thyme herb plants at Tagawa Gardens in Denver, Colorado

Find time for Thyme

The wide varieties of thyme you can grow may surprise you.  Tagawa’s has a big selection of culinary thyme that does well in pots.   Thyme can also be grown indoors on a sunny windowsill.  Thyme needs well-drained soil and full sun, but will tolerate a bit of shade.

9News Garden Guru (and frequent Tagawa Gardens teacher) Rob Proctor grows an ornamental variety of time in his herb garden.  “Creeping Red” thyme actually produces pink flowers… by the zillions!  These low, tight mats frame beds filled with other delicious edibles like basil and garlic.  His thyme borders are never without visiting honey bees on summer days.

Tagawa’s also carries a foot-step friendly line of ornamental thymes called “Stepables” that will grow in pathways between pieces of flagstone or pavers and tolerate light foot traffic.  It’s not edible, but it is lovely.

Lavender Munstead at Tagawa Gardens in Denver, Colorado

Mmmmm….   Lavender!

Spanish Lavender plants at Tagawa Gardens in Denver, ColoradoHere comes my soap box:  There are two plants that even small-space and novice gardeners should grow in Colorado.  They’re lavender and garlic.  We’ll talk about garlic in the September, when Tagawa’s has its annual “Ga-Ga for Garlic” Festival.

For now, let’s talk lavender.  I love lavender.  The bees love lavender.  Most everyone I know loves lavender.  And it’s easy to grow, as long as you can give it two things.  It needs full sun, meaning at least six hours of good, bright light.  And it needs well-drained soil.  The quickest way to kill lavender is to keep its roots too wet.

Lavender hidcote at Tagawa Gardens in Denver, ColoradoLike rosemary, lavender has woody stems and does not make a good houseplant.  But put it outdoors in a bed or a good-sized pot…. say eight inches across…. give it the sun and the soil it needs, and you’re off!  Lavender usually won’t overwinter outdoors in a pot, but the fragrance and blossoms are well worth growing it as an annual.

Hidcote” and “Munstead” are two tried and true lavenders that do very well as perennials in Colorado.  More varieties seem to be coming onto the market every year.  Some lavenders are ideal for cooking.  Others are best suited for crafts.  Some like Spanish lavender have big blooms but are an annual, so be sure to find out if the ones you fall in love with are annuals or perennials to help you decide where to put them for best results. Our Perennials or Herb Department staff can guide you to the plant that would work best for you.

Be sure to join us for Tagawa’s “Lavender Fields Forever” on July 23rd.  Our lavender festival is all about plants that do well here in Colorado, and how you can use them once the flowers are ready to harvest.

Hope to see you there!

    We live in Nucla,Co on the western slope. We are looking for the best variety of lavender for our area. After trying a few, unsuccessfully I might add, we are not sure about it but absolutely love it.
    We appreciate any help you offer.

      Dear Mary and Roger,
      You live in great lavender-growing country! There are so many good varieties than can thrive in Colorado.
      Which ones you choose depends on how you want to use the lavender you harvest; i.e., for cooking, for extracting oil… for crafting. Two of the tried-and–true varieties that do well for me are “Hidcote” and “Munstead.” Denver Botanic Gardens is also having excellent results with a lavender called “Phenomenal” at their gardens at Chatfield Farms. You might check the Western Colorado Lavender Association’s website for more recommendations. You have a lot of expertise right in your own back yard! Good luck!

      My best,

    I’ve tried for two summers to grow instead lavender in our Ricky Ford area. No luck. It’s supposed to grow here. My friend said it’s too cold here. Temps are occasionally -10. We have mild winters in the Lajunta areas as a general rule. I told her we grow it in IL. I had s success with a big pot on a patio in Aurora. Maybe I should that. What are your suggestions? Thanks.. also some good perrenial herbs

      Dear Kaitte,

      There are a couple of varieties of lavender than can do quite well on the plains…. “Hidcote” and “Munstead.” I lost some lavender during its first winter because I failed to “winter water.” That’s a good practice throughout the landscape, especially with plants that have been in the ground for three seasons or less. A inch or so of water once a month when we haven’t had good soaking snows can make all the difference in keeping those maturing roots systems alive. There are a lot of beautiful lavenders on the market that aren’t hardy here, especially those sold as “French” or “Spanish” lavender. But if you take care with the winter watering and mound up some loose mulch once we’ve had a hard freeze, your hardy lavender should be okay. And congratulations for wintering over a lavender in a pot! That’s usually a challenge, since the root balls tend to freeze on our average winters. It only takes one night of significant cold to take them out.

      My best,
      Luan Akin

    I bout 2 lavender trees at Costco and was going to plant them outside—is that not a good idea?
    should I stick to pots and bring them in during the winter months
    they are about 18 to 24 inches–I love them and don’t want to end up losing them
    thank you!

      Sorry I didn’t see you question sooner. Where did the month of May go?!

      Re: your lavender from Costco. Lavender generally grows as a woody shrub, but it’s possible your plants have been pruned to look more like trees.

      If you have the tags from the plants, they should tell you what specific strain of lavender you’ve bought. Some varieties are hardy here, some aren’t. You could certainly bring the tags in to Tagawa’s and ask the folks in our perennials department to help you figure that out.

      Lavender is “iffy” as a houseplant. It needs at least six hours of full sun to thrive, and that’s usually hard to do indoors. They’re also inclined to dry out over the winter.

      Tagawa’s will have a lavender-focused day on July 14th. We’ll have classes talking about which varieties do best here, how to maintain them properly, etc. I’d urge you to check out the schedule on the website calendar. If you love lavender, it’s time well-spent.

      Good luck!

    Hi Luan,
    Have you had any luck growing cilantro in the ground with the hopes that it will come back next Spring? Also, what is the best way to get rid of overgrown mint?

    • Luan Akin

      I’ve had reasonably good luck growing cilantro in pots, but I haven’t tried it in the ground. It has such delicate foliage, I’m guessing it’s just not up to the task. If you need/want lots of cilantro, you might try growing succession crops from seed. It comes up quite easily. If you have a few pots, you can sow a new crop just as the previous crop is being harvested. And I’d suggest you give it morning sun only. I think out toasty afternoon sun is too harsh for it here.

      If you’ve had mint get away from you (and a lot of us have!), you can try to dig it out with a shovel, but it has pretty stubborn runners. Miss one or two, and it will return. If it’s really persistent, you can take some weed killer and paint it directly onto the mint leaves only.

      Good luck!

    Hi Luan,
    I am in Littleton and would love to learn more about the master Gardner program you took? Also is there anywhere you recommend that assists with bed planning for herbs? Thanks! Allison

      Hello Allison—

      Tagawa’s has classes every spring or early focusing on how to grow herbs. I don’t have the schedule for next year, but I’d definitely watch for those. Tammy Hartung is the lady who grows all of Tagawa’s organic herbs. She also teaches classes at Tagawa’s now and then, and those are well worth attending.

      Tammy has a couple of excellent books on the market. “HOMEGROWN HERBS” is a terrific resource.

      Re: the Master Gardener program…. Each county runs its own program. They have to follow basic “rules” from CSU, but there are some more subtle difference. Way back when, I took the class through Douglas Co. Extension Service. Some of our classes were in Castle Rock at the fairgrounds. For others, we joined up with the Arapahoe Co. Extension Service. I’m not sure if that’s still the case.

      Below is the Arapahoe Co. Extension Service link to their Master Gardener program. I thought it was a wonderful experience. I’d garden a fair bit, but it was kind of loosey-goosey… I was enthusiastic, but not always successful. Depending on your own gardening experience, it may seem a bit overwhelming at first, but you’ll have a great time and come home with your head spinning… in a good way!

      I strongly encourage you to give it a go, and good luck!!

      My best,

      Luan Akin
