Do you use white flowering plants in your landscape?

I do.

However, some people tend to overlook white flowers in favor of flashier colors such as yellow, orange or red.  But did you know that white flowers can help show off the other colors in your landscape by providing color contrast?

In addition, white flowering plants also have a visually cooling effect in the garden, which is a welcome sight in the Southwest where summers are hot.

I’d like to share with you some of my favorite white flowers, all of which do well in the Southwestern landscape.

Bush Morning Glory (Convolvulus cneorum)
 
Pretty white flowers with yellow centers are just one of the reasons people love Bush Morning Glory. Its silvery foliage is another great color that it adds to the landscape.
 
In the desert, the flowers appear for several weeks in spring before fading away. However, the silvery foliage is evergreen and will add great color contrast when planted nearby plants with dark green foliage.
 
Do you have an area that gets full afternoon sun and reflected heat?  Bush Morning Glory can easily handle it while looking great.
 
Hardy to zone 8, bush morning glory grows approximately 2 ft. tall and 4 ft. wide.  Prune back in spring, after flowering has finished by 1/2 its size.
 
White Gaura (Gaura lindheimeri)
 
White Gaura is a flowering perennial that has a prominent place in my landscape. It has small flowers, shaped like small butterflies, that start out pink and turn white as they bloom.
 
 
This lovely perennial does best in filtered sun and flowers in spring and fall. It requires little maintenance other then shearing it back in spring to 1/2 its size.
 
White gaura is related to the pink variety ‘Siskyou Pink’, but has a bushier appearance and grows larger – approximately 2 1/2 ft. wide and tall. This native perennial is hardy to zone 6 gardens.
 
‘White Cloud’ Texas Sage (Leucophyllum frutescens ‘White Cloud’)
 
While most of us are more familiar with the purple flowering Texas sage shrubs, there is a white variety that is well worth adding to your landscape.  
 
‘White Cloud’ Texas Sage can grow large, 6+ feet tall and wide, if given enough space. It thrives in full sun and in summer and fall, periodic flushes of white flowers cover the silvery green foliage.
 
Avoid the temptation to excessively prune this shrub, which decreases the flowering and is not healthy for this type of shrub.  Hardy to zone 7, this shrub looks great when used as an informal hedge or against a wall.
Hedgetrimmers aren’t needed for pruning Texas sage. My Corona Compound Loppers are what I’ve used to prune mine for over 10 years with some hand pruning as needed for wayward branches.

Texas Olive (Cordia boissieri)
This Texas native is a huge favorite of mine – Texas olive is a large shrub or small tree, depending on how you prune it. It has dark green, leathery leaves, and beautiful white flowers, which appear spring through fall on evergreen foliage.
 
Whenever I see this shrub, I always take a moment to admire its beauty, since it isn’t used often in the landscape – but it should be!
 
Small fruit, resembling an olive is produced, which are edible. They thrive in full sun. Allow plenty of room for it to grow as it gets 25 ft. tall and wide. Hardy to zone 9, the only drawback of this white-flowering beauty is that it can be a little messy, so keep away from swimming pools.
 
All of these white flowering plants are drought tolerant and do well in hot, arid climates.  
 
Do you grow any of these in your garden? Which is your favorite?
 
As beautiful as these plants are, I have more to show you next time in Part 2 next week!
What type of plants comes to mind when you are planning what to plant in your containers?
 
I’m willing to bet that purple hopbush (Dodonaea viscosa ‘Purpurea’) and bush morning glory (Convolvulus cneorum) probably weren’t the first plants that came to mind.
 
Admittedly, I tend to think of using plants known for their flowers or succulents in my containers.  That is until a trip to California that I took this past April.

 

In the Napa Valley region of northern California, sits Cornerstone Sonoma, which describes itself as “a wine country marketplace featuring a collection of world-class shopping, boutique wine rooms, artisanal foods, art-inspired gardens.”
 
Believe me; it is all that and more.  There was so much to see, but what caught my attention were some unusual, yet beautifully planted containers.
 
Purple hopbush (Dodonaea viscosa ‘Purpurea’), shrubby germander (Teucrium fruiticans), and violas.
There were square steel containers filled with plants that are well-known for their foliage and are seldom used in pots.
 
I was intrigued, especially when the plants used were also popular in the desert Southwest.
 
There were quite a few things about this type of container planting that appealed to me.
 
One, it is low-maintenance – no deadheading required.  Just some light pruning 2 – 3 times a year, to control their size. Second, the plants are all drought tolerant (with the exception of the violas). Lastly, I like seeing new ways of doing things and using plants prized for their foliage in containers is something we don’t see too often.  
 
Fast forward a few months, and I decided to rethink what to add to the large, blue planter by my front entry.  So, I thought, why not try the same arrangement?
 
 
Granted, the plants are smaller than those I saw in California, but given a few months, they should grow in nicely.
 
As you can see my new plants are rather mall, however, the purple hopbush will grow taller and its evergreen foliage will add shades of purple and green to this space. Furthermore, this shrub is one of those highly-prized plants that do well in both sun and filtered shade.
 
The silvery-gray foliage of bush morning glory creates a great color contrast with the darker greens of the other plants. While it may not flower much in this semi-shady corner, I want it for its silvery foliage.
 
In addition, I want to use a plant that has bright green foliage, so I have a single foxtail asparagus fern (Asparagus densiflorus Myers), which will thrive in this semi-shady exposure. 
Maintenance will be relatively simple with periodic pruning to keep wayward branches in check. Fertilizing in spring and late summer with a slow-release fertilizer such as Osmocote will be all that’s needed to keep my container plants happy.
 
Do you have any plants with attractive foliage that you would use in containers?
