Why do I love grevilleas for drought-tolerant, deer-resistant gardens? Let me count the ways:
1. They take 100-degree days in the full sun like a champ, never showing a hint of fatigue (which makes sense since they’re native to Australia!)
2. They’re also deer-resistant, thanks to irritating substances in the foliage and flowers. I’ve watched entire families of deer walk through my grevilleas, not even bothering to try a nibble.
3. Grevilleas look just as good in the winter as they do in the summer (in my zone-9 climate.) A few varieties, in fact, bloom heaviest in February and March, when little else is blooming.
4. Grevilleas bloom intermittently throughout the year – no ‘one hit wonders’ with this group! To the delight of hummingbirds and pollinators, these shrubs are covered with blooms.
5. Their flowers come in a HUGE range of colors, shapes, and sizes. From 6-inch, spidery-shaped flowers to 4-inch toothbrush-shaped flowers, all the way down to 1-inch curlicue blooms.
Flower colors range from hot reds, oranges, and pinks to pastel shades of creamy white, soft peach and yellow.
6. Grevilleas come in a HUGE range of sizes, from towering 15’+ varieties to mid-size 4’ beauties, all the way down to 2’ groundcovers.
This makes grevilleas ideal for evergreen privacy screens, year-round ‘bones’ of a garden bed, or winter-blooming groundcovers.
Now, for my cold-climate readers, a few varieties do well down to zone 6 (some survive down to 10-15 degrees), but for the most part, grevilleas do best in warmer climates. I’ll provide links to grevilleas that can withstand colder temps at the end of this post.
However, it’s important to note that it’s not necessarily the colder temps that kill them; it’s the lack of fast-draining soil, which does them in.
Grevilleas hate soggy roots and standing water.
As mentioned, grevilleas require very little water once established. In the hottest summer months, I deep-soak them every other week or so and rarely (if ever) add fertilizer.
If the foliage of your grevilleas are yellow, they may need a little help from you to green back up.
Be extremely cautious when feeding grevilleas as most cannot tolerate much phosphorous.
Therefore, look for a fertilizer with 2% or less phosphorous (which, admittedly, in the US is difficult to find.)
After experimenting with greening up yellow foliage, I wanted to let you know that I’ve had fantastic luck with this Ironite spray.
It’s important to follow directions and apply it when the ground is moist (perfect for early spring after a rainfall) and give it time to work. My grevilleas have taken up to 6-8 weeks to show results.
For the most part, grevilleas respond really well to pruning, so don’t worry about cutting back a wayward branch.
Pruning is also a great way to encourage even more blooms to form at the tips of the new growth, so prune away!
I’ve been designing with grevilleas for the past 20+ years, and am thrilled to see more and more varieties available in nurseries.
So with that, here are my favorite grevilleas that I recommend for your gardens.
Groundcovers and front of the border varieties (3-feet or less)
Grevillea ‘Fanfare’
This is the most amazing weed-suppressing, low-water, EVERGREEN groundcover I’ve ever planted. I only wish it was more available, and have only seen it twice in nurseries.
If you’re lucky enough to find ‘Fanfare’ buy it – if not for you, for another gardening friend who needs a ground cover that grows 1’ tall x 10-15 feet. Yes, it spreads wide yet remains low. It has unique ,deeply lobed foliage, but the dark red toothbrush-shaped flowers steal the show.
Grevillea ‘Mt. Tamboritha’
This ground cover has an entirely different appearance than the previous grevilleas mentioned.
It has stubby succulent-like foliage, which grows close to the stem, and small coral & pale pink flowers. ‘Mt. Tam’ is hardy down to 25 (possibly even 20, by some accounts) and blooms for MONTHS throughout the year, starting in January. January!
It’s a very showy front-of-the-border, evergreen plant and one of my top 10 favorites ever. I use them often in my designs, placing them along the front of the border where they’ll bloom almost continually with little water.
Growing to 1’ x 4’, they gently drape themselves around other nearby plants, making them indispensable in my garden designs.
People often ask me if they can substitute ‘Coastal Gem’ for ‘Mt. Tam’ since they’re so similar in size. I rarely do this in my own designs, as ‘Coastal Gem’ is a bit more open growing with flowers that aren’t as vibrant as ‘Mt. Tam.’
Grevillea ‘Bonnie Prince Charlie’
I’m in love with the vibrant red-orange and yellow blooms of this variety, adding so much color to my winter garden. Growing to about 2 1/2 tall x 4′ wide, makes ‘Bonnie Prince Charlie’ perfect for the mid-border.
(fun fact: this isn’t named after Prince Charles, but rather after a young ruler from the 1700’s!)
Grevillea ‘Magic Lantern’
I first spotted this variety at the UC Davis Garden and fell in love with the feathery gray foliage combined with bright red blooms.
This variety grows between 2-3 feet and spreads to 6-10 feet, so make sure to give it plenty of room!
Mid-Sized, ideal for the middle of the border (3 to 6-feet tall)
Grevillea ‘Superb’
The aptly named ‘Superb’ has been a showstopper in my garden for years, blooming intermittently throughout the year.
Quickly growing to 4’x4’ (sometimes a bit larger), ‘Superb’ wants full sun, fast drainage, and just a little supplemental water once established.
Given these conditions, you’ll be rewarded with hundreds of large, 6″ flowers of soft coral and orange.
Grevillea ‘Peaches & Cream’
Similar to ‘Superb’ is ‘Peaches and Cream,’ growing to 5’ tall, and a bit wider to 7.’ If you prefer pastels in your garden, this variety is for you, with loads of spectacular apricot and cream blooms.
It’s not just hummingbirds who love these flowers; other birds do as well (like the bushtit, below.) In fact, just today I saw a female oriole devouring the nectar from this same shrub!
Grevillea ‘Little Honey’
This fast-growing grevillea grows to 6’ x 10’ wide with gorgeous orange/yellow blooms.
Mine is planted on a slope (great for fast drainage, which they LOVE) and under a tall toyon shrub and magnolia tree. This way, it gets a bit more overhead protection from frosty nights, which is necessary as this variety is a little more frost-tender than others in my garden.
Grevillea victoriae ‘Murray Valley Queen’
Naturally found in the higher elevations in Australia (where they even survive light snowfall), ‘Murray Valley Queen’ is one of the more cold-hardy grevilleas, surviving temps to 5-10 degrees.
As you can see, the rounded, elongated foliage is very different than other varieties resulting in a more ‘traditional shrub’ appearance.
Grevillea lavandulacea ‘Penola’
This variety is happily growing in my client’s garden (click here for a before and after.)
The gray foliage contrasts nicely when surrounded by shades of green, and those bright pink flowers are absolutely darling. It grows to 4-5’ tall by 8’ wide, so make sure to give it plenty of room to stretch out!
Grevillea ‘Ned Kelly’
Named after an Australian outlaw in the 1800’s, ‘Ned Kelly’ is a cross between ‘Robyn Gordon’ and’ Superb’.
This variety grows faster than ‘Superb’ and is a bit taller and more upright. As you can see, below, the flowers are more vibrant with deep, rich shades of coral, yellow and orange.
It also seems to be more frost tolerant than its parents, surviving winter nights that dip into the 20s.
Grevillea ‘Deua Flame’
‘Deua Flame’ is an endangered variety and is reported to be a super easy grevillea to grow.
However, in my experience both in the Bay Area and now here in Granite Bay, it’s been challenging to get it to grow.
My 3rd attempt, however, has paid off ,and my 3-year-old plant is now starting to flower with very little attention from me.
This variety seems happiest planted under the canopy of tall and wispy live oak trees versus planted in the blazing hot sun.
Grevillea ‘Scarlet Sprite’
Growing to 4’x6’, ‘Scarlet Sprite’ has prickly needle-shaped foliage with profuse, red flowers.
It’s so sharp, I’ll often use it as a ‘barrier plant’ to keep deer away from other, more munchable plants – works like a charm!
Towering Varieties – great for impact and screening (6’-15’ tall)
Grevillea ‘Long John’
‘Long John’ is one of my very favorite varieties of all time. It quickly grows to 12’ x 6’, but I’ll warn you – I’ve seen them grow upwards of 15’ when happy.
Its unique foliage resembles very long, thin pine needles, creating a wispy see-through effect in the garden.
However, despite its imposing size, this plant’s light and airy nature helps prevent it from appearing too bulky in the garden. The flowers are a dark rose-pink color that attracts hummingbirds as well as tons of beneficial insects and bees.
***Grevillea ‘Bonfire’
As you can see from this photo, a towering ‘Long John’ is on the very top of the hill, with the mid-sized ‘Bonfire’ in the front.
While I loved this combination, I can no longer recommend this plant as, unlike any of the other varieties I’ve grown, ‘Bonfire’ hangs on to its dead foliage for dear life.
In fact, it’s next to impossible for me to pull it off, resulting in a half-dead-looking plant for most of the year. Which is such a bummer, as those fire-engine-red blooms were so pretty!
Grevillea ‘Moonlight’
‘Moonlight’ is another of my favorite tall varieties, growing to a towering 15’ tall.
It’s 6” long creamy white flowers are literally dripping with nectar, whipping the bees into a frenzy.
I’ve read that hummingbirds tend to ignore this variety as they’re not as attracted to white flowers. Interesting, as I’ve definitely noticed this to be true in my own garden! I just thought they were busy with my other grevilleas, but now I think it’s because of the white colored flowers.
Either way, I still love this variety and the way the flowers glow in the setting sun
Grevillea ‘Canberra Gem’
This tough and fast-growing variety’s dark green, needle-like foliage adds a welcome ‘lush’ quality to hot and dry gardens.
And, when covered with dark rosy-red blooms, it appears even more lush! It definitely doesn’t look like most drought-tolerant plants.
This is one of my favorite combinations that I pass by on my morning walks. Just look at this fantastic spring-blooming combination of the blue-flowered ceanothus, the magenta Redbud tree, and the red grevillea blooms.
The needle-like foliage is a bit prickly, so you’ll want to wear gloves when pruning.
As promised, here are a few more articles that you may find interesting:

Hi Rebecca,
So grateful to have stumbled across your Grevillea blog! It inspired me to install ‘Mt. Tamboritha’ for a (now very happy) client who wanted something showy and long-flowering to spill over her brick patio wall. I now find myself recommending Grevilleas to clients on a regular basis and sending them the link to your extremely handy guide.
Thank you!
Paul
Hi Paul, and your comment makes me so happy! Aren’t Mt. Tam’s wonderful? I can’t sing their praises loud enough. In January I noticed mine were covered with hungry black-tailed bees and was so surprised to see them out so early in the year. After googling them, I read they’re some of the very first to emerge and are desperately looking for blooming flowers (Mt Tam to the rescue!) Another one that I’ve fallen in love with is the ‘Bonnie Prince Charles’ (I updated my grevillea post just two days ago to include this, as well as how to green up yellow leaves.) I’ve seen this newer variety in your area so you might have luck finding it at your nurseries. Thanks again!
Hello! My home came with what I think is a Grevillea “Peaches and Cream.” I love it, and I want to take good care of it. It’s putting out flowers, but the leaves are yellow-lime green than the medium green I’ve seen in photos. It has green leaves closer to the trunk. Could it be a type of Grevillea with light-colored leaves? Might that be winter foliage? Or might something be wrong? We’ve had a lot of rain this winter, and the soil has a lot of clay. By the size of the trunk, I’d say it’s been around for a few years. I hope it improves when the dry season starts, but if there is something I could do to help it thrive, I’d like to try. Any advice is appreciated. Thank you!
Hi Tracey, I have a feeling you definitely have a ‘Peaches & Cream’ variety, which is more inclined to have yellow leaves than other varieties (at least in my part of the world.) Your comment prompted me to update my post, which includes information how I green-up my leaves using ironite. While it could be the clay and the rainy winter, I have a feeling you need to apply ironite (use caution so you don’t burn the foliage which I’ve done in the past. But even if you do, it won’t kill the plant, just look unsightly for a season or two) and give it plenty of time (6-8 weeks) to see results. Good luck!!
Thank you! I will give that a try.
Is there a Grevillea that will take some shade. I have 3 peaches and cream and they struggle on the north side of my property. When is the best time to move them to a sunnier location.
Greetings from Cambria
Hi Darlene, I’m sorry to hear about your Peaches & Cream tho it isn’t surprising as grevilleas really do want as much sun as you can give them. In my experience, the larger grevilleas like yours hate to be relocated – I’ve lost so many that way – so I’m not sure if you’ll be able to save them, but its worth a try if the alternative is throwing them away. You might try any time before they start really growing again once the weather warms up, carefully trying to get as much of their rootball as possible without disturbing them too much. The only grevillea that I’ve had luck with in ‘partial’ shade is the groundcover, ‘Mt. Tamboritha’ – all of the other larger varieties tend to sulk in shade. I’ve been experimenting with planting westringeas in the shade and have had great luck with ‘Smokey’ and ‘Morning Light’, if that’s a consolation? They certainly don’t produce those gorgeous flowers, but they have tiny little flowers that the hummingbirds love, and are evergreen with lovely, delicate foliage and are about the same size as the ‘Peaches & Cream’ Good luck and let me know how it goes!
I came across your website while doing a search for plants that appeal to hummingbirds. What wonderful pictures you have along with useful information. The peaches and cream grevillea is stunning. I look forward to reading your past posts. Thanks for including the pertinent links.
Hi Beth, welcome to my blog and thanks for letting me know you’re enjoying it!
I’ve been struggling with what to plant in the full sun part of my garden so the timing of this post is perfect. The area is a berm which was made using rocky, poor soil. The beautiful taller varieties would also provide screening. I hope I will be able to find them in local nurseries. I love your informative posts.
Berms are perfect, Mona, as they’re fast draining (which are a must for grevilleas) and full sun, too? You’ve got the ideal situation – good luck sourcing them. Nurseries are getting better and better about carrying different varieties.
I never knew there were so many beautiful flowers on grevillias so I really enjoyed this post. My previous home came a mature Grevillea ‘Noellii’ which was planted on a rocky slope and received no summer water or supplemental plant food. I did not like the old shrub and didn’t care what happened to it, but over the years I came to respect its’ endurance. It grew next to a well traveled deer trail and was not touched by deer, ground squirrels, gophers, voles, or rabbits.
Hi Elizabeth – you’re not the first person to tell me grevilleas weren’t their favorite shrub, but because they’re SO darn tough, they’ve grown to love them. I’m glad you gave that poor, neglected trooper the respect it deserved! 😉 With the difficult growing conditions in my own garden, I’m a huge fan of just about anything that wants to grow here.
