Wild About Penstemons

, , , ,

I adore flowers of all kinds, but I must confess that my favorite types look as if they belong to a cottage garden, which probably explains why I am wild about penstemons.

I adore flowers of all kinds, but I must confess that my favorite types look as if they belong to a cottage garden, which probably explains why I am wild about penstemons.

There are many different species of penstemon with varying colors, ranging from shades of pink to red with some white ones thrown in.

All penstemons are native to the western half of North America where they thrive in well-drained soil.  Most grow in higher elevations, and all are drought-tolerant.  For those of you who love to grow native plants that are low-maintenance, penstemons are a must-have.

I like plants that add a touch of drama to my garden and penstemon do a great job at that when they send up their flowering spikes that tower over their lower cluster of leaves.  Bees and hummingbirds love their flowers and it is fun to watch their antics as they sneak inside the flowers for nectar.

While penstemon may look rather delicate, it is anything but as it can survive temperatures over 100 degrees and temperatures that dip anywhere from 15 degrees Fahrenheit all the way down to -30 degrees, depending on the species.

The bloom time for penstemon depends on the species as well as the climate they grow in.  For desert dwellers like me, most bloom in late winter into spring.  Each year, I eagerly await the appearance of the first unfolding flowering spikes of my firecracker penstemon (Penstemon eatoni)  to emerge in January.

Parry’s penstemons (Penstemon parryi)

In my garden, Parry’s penstemon (Penstemon parryi) is another favorite of mine in the garden, and its flowers begin to open in late February.  This year, I am growing pineleaf penstemon (Penstemon pinifolius), which is a new one for me and I am curious to see how it will do.

Another penstemon that I am anxious to try is rock penstemon (Penstemon baccharifolius), which blooms spring through fall.  Lastly, I have added Palmer’s penstemon (Penstemon palmeri) to my garden.  I used to grow it years ago and was happy to incorporate it back into my landscape.

It’s important to note that penstemon grows best when grown in the western half of North America.  The season in which they bloom can vary depending on the USDA zone.  In my zone 9 garden, I begin to appear in January and last through spring. For those who live in colder climates, penstemon will bloom later in spring or even begin flowering in summer.  However, no matter when they bloom, penstemon are sure to add beauty to the landscape with a touch of drama.

Timely Pruning Produces Second Round of Flowers

There are many flowering perennials that I can think of that only flower once a year and many people think that the lovely blooms of penstemon count among them.

But, did you know that if you prune the flowers just as they begin to fade that you can stimulate another flush of colorful blooms?

I’ve grown penstemon for years and recently planted a Parry’s penstemon in my front yard. I enjoyed seeing its pink blossoms waving in the breeze and the hummingbirds who stopped by for a drink of nectar.

The individual flowers began to fall, leaving only a few behind, which is the best time to prune the flowering stalks back.

If you wait too long, the chances are that you will lose your window of stimulating your penstemon to produce more flowers. It’s best to do this when there are a couple of blossoms left on the plant.

This is what my young penstemon looks like right now, but within a couple of weeks, new flowering spikes will begin growing.

The reason that pruning off the first set of flowers stimulates a second bloom period is that the penstemon’s goal is to produce seeds. To do that, they produce flowers to attract pollinators and once pollinated, the flowers drop and the seed develops. However, when by pruning off the flowering spikes when there are a few flowers left, we disrupt the cycle and the plant will produce another set of flowers for the purpose of producing seeds.

Doing so will promote a second bloom for several penstemon species, including firecracker penstemon (Penstemon eatonii) and Parry’s penstemon (Penstemon parryi).

Pruning and Blooms in the Spring Garden

2 Flowering Water-Wise Beauties Ready for Spring

,

What does your garden look like in early spring? Does it somewhat boring? How about adding some color and interest to your garden by adding some water-wise flowering plants?


This week, I had a fun project to work on – in partnership with Monrovia, I was asked to select two types water-wise plants for the landscape. So, I headed out to my local nursery with a mission to select from the different water-wise Monrovia plants available.

Once I arrived at the nursery, I was faced with a number of different Monrovia plant choices from succulents, cacti, shrubs and perennials. After a some time going back and forth, I narrowed my choices down to these two water-wise, flowering beauties.

Parry's penstemon (Penstemon parryi)

Parry’s penstemon (Penstemon parryi) has long been a favorite perennial of mine. I love the ‘cottage-garden’ look it provides with its pink spikes that appear in late winter and on into spring.

It is quite versatile in the landscape where it can be used in wildflower gardens, planted in a perennial bed or simply placed next to a boulder.

My next plant choice was a flowering succulent. 

Blue Elf aloe (Aloe 'Blue Elf')

Blue Elf aloe (Aloe ‘Blue Elf’) is a newer aloe species that is perfect for small spaces. It adds welcome color with its orange flowers that appear in late winter into spring.

I have been using this small aloe a lot in recent landscape designs (like the one above) including in narrow planting beds, in entries and also in pots.


Both of these flowering plants are water-wise choices and perfect for the drought tolerant garden.

I loaded my new Monrovia plants up and started home.

On the drive home, I could see the flowers from my new plants in my rearview mirror and I couldn’t wait to find new homes for them in my garden.

I played with a number of potential locations in the garden for my new parry’s penstemon, but decided on planting it next to a boulder. Plants like this penstemon look great next to boulders where their different textures provide great contrast.

I didn’t have to try different spots for my new Blue Elf aloe – I knew that I wanted it for one of my containers in the front entry.

Monrovia plants can be found at Lowe’s garden centers as well as at many local nurseries, which is where I found mine.  You can also order Monrovia plants online.  The quality of their plants is excellent and the only problem you’ll have is choosing from the large variety available.
