Clematis ‘Sapphire Indigo’ is looking quite stunning in the garden. This fascinating clematis isn’t a vine or a clump. It could be best referred to as a short sprawler. We’ve used it throughout the gardens as a groundcover filler between both shrubs and other perennials. It doesn’t actually spread, because in the winter, it dies back to a tight rootstock. We find this absolutely exceptional, flowering for us from spring through early fall. Hardiness is Zone 4a-8b.

I weep for Alliums–of all sizes
Flowering in the garden in late April were an array of amazing Alliums. The top image is Allium ‘Ambassador’, a hybrid of Allium stipitatum x giganteum. This sterile gem is a 2005 release from the breeders at Hollands’ Fa. A. Langedijk.
Below that is the smaller Allium drummondii, a native to the prairies from South Dakota to Texas.
The Mourning Widow’s Skirt
The skirt of leaves of the European Geranium phaeum (mourning widow) are always a favorite in the early spring garden. We truly love this clump-forming hardy geranium, that behaves superbly in the woodland garden.
In the wild, the amount of black pattern on the foliage varies, but Geranium phaeum ‘Samobor’, is an exceptional clone, originally discovered in the wilds of Croatia. The foliage is topped in early spring, with short stalks of small purple flowers, but it’s the foliage that makes this a standout. Hardiness is Zone 4a-8b.
A Contrast in Styles
Iris x robusta ‘Gerald Darby’ is looking lovely today in front of a patch of Narcissus ‘Beautiful Eyes’. So many fun combinations are possible if you grow enough different plants.
A Tweet from the Cordial Canary
Ajuga ‘Cordial Canary’ is one of the new generations of well-behaved bugleweed selections, this from the work of Chris Hansen. It looks pretty amazing for mid-March at JLBG. We love colorful groundcovers that play nice with their surroundings. Zone 4a-9b.
Not so Boring Borage
One of our favorite borage family members, Trachystemon orientalis is flowering this week in the woodland garden. Native to Bulgaria and Turkey, this late winter-flowering groundcover is quite tough. The foliage dies away in fall, but not long before the emergence of flowers and a new round of foliage. Hardiness Zone 6a-8b.
Here’s a garden shot just prior to our expected first freeze of the year. Foreground to back: Muhlenbergia lindheimeri, Salvia darcyi, Juniperus conferta ‘All Gold’, Cuphea micropetala, Salvia ‘Phyllis Fancy’.
Rockin’ Deep Purple
We’ve had Salvia ‘Rockin’ Deep Purple’ on trial since 2018, and it’s now headed for our January Plant Delights catalog. Although we love the Argentinian Salvia guaranitica, it spreads far too fast to be useful in many of our garden beds. We have been trialing a number of hybrids with Salvia guaranitica and an array of different clumping species to find one that has winter hardiness, but doesn’t take over the garden.
Salvia ‘Rockin’ Deep Purple’ from California’s Brent Barnes, has lived up to all of our expectations, as long as you have enough space. For us, a single clump measures 5′ tall x 10′ wide…a far cry from the 3.5′ tall x 2.5′ wide size that’s often marketed on-line. Below is an image of the flower power it’s still showing in early October. The bumblebees love it as much as we do.
Ajuga ‘Parrot Paradise’ is one of many new next generation colorful ajuga groundcovers that have hit the market in the last few years. These have been amazing in our trials, as you can see from the October photo below. Best of all, we haven’t seen any seedlings, which have been a problem with several of the more common clones in commerce. We think both the color and growth habits are truly outstanding.
A Shot of Summer to Go
Here’s a recent garden combo that we’ve been enjoying with purple eucomis (pineapple lily), Agapanthus ‘Navy Blue, backed with Foeniculum vulgare ‘Purpureum’ (bronze fennel).
It fascinates us that such a widespread native like Eustoma exaltatum isn’t more widely grown in gardens. Often known by the common names prairie gentian or lisianthus, eustoma is prized by flower arrangers, but not gardeners. Eustoma is native from coast to coast…Florida to California, and north to the Canadian border in Montana.
In the wild, Eustoma exaltatum is a short-lived perennial that can also behave as a biennial or even an annual in some sites. The key is to plant it where it can happily reseed as we have done in our gravelly crevice garden, which is odd, since in the wild, they are found in moist meadows and streamsides.
Below are our plants in peak flower now, during the brutal heat of summer. So far, we’ve struggled to keep this happy in a container, in the hopes we could make this available, but we continue to try.
Commercially, eustoma has been hybridized ad nauseam to create better cut flowers, but these hybrids seem to have lost all of their perennial nature compared to the wild genetics. Our plant pictured below is the large (2′-3′ tall) subspecies russellianum from wild collected seed from Bastrop County, Texas.
This is the time of year when the tiger swallowtails feast on our many patches of the amazing native Stokes aster. Our favorite clone is the upright growing Stokesia laevis ‘Peachie’s Pick’. Moist soils are best, but stokesia tolerates some dry conditions on a short term basis as long as it has 2-6 hours of sun.
Adding Vulgarity to the Garden
We love “vulgar” plants, which are good for providing unexpected shrieks from garden visitors. One of our favorite plants for evoking such moments is the European native, Dracunculus vulgaris. For those who took Latin in school, you’ll know that the English translation of the Latin name is Vulgar Dragon’s Butt. This fascinating spring ephemeral is native to very rocky, dry sites in the Southwest corner of Turkey, the Aegean Island (inc. Greece), and into the Balkans.
Virtually all of the material in commerce, which comes from the Turkish populations, are the red spathe/purple spadix form. Once you move to Crete, the inflorescences take on a different color theme with blends of white in spathe, and spadices which range from black to yellow. Below are a few which flowered at JLBG this spring.
We inherited the work of the late aroid researcher Alan Galloway, who actively hybridized dracunculus in an attempt to study the genetics as well as create new color forms for gardeners. Once final selections are made, these will require tissue culture for reproduction. Without tissue culture (dividing plants with a tiny knife), commercial quantities could never be obtained. Wish us luck!
African Gold and Picasso
Below are two variations on a theme…calla lilies in the garden. Here is Zone 7b, both are reliably winter hardy in the ground.
The striped-leaf selection of the winter-blooming South African native, Zantedeschia aethiopica ‘African Gold’ has looked fabulous all spring, where we have it planted in a seep, which gets full sun for 3-4 hours in the morning.
Zantedeschia ‘Picasso’ is a hybrid, created using several of the summer-flowering South African native calla lily species. Here it is in our garden in mid-June, where it gets 4-6 hours of sun daily, and the soil stays reasonably moist.
Hi Ida Maia
Looking great in the crevice garden this month is the Pacific Northwest native, Dichelostemma ida-maia This odd little bulb is a member of the Asparagus family…so that makes it as cousin to agaves, hostas, and asparagus. In the wild, it is only found in coastal meadows and into forest edges and partial woodland openings in Northern California and Southern Oregon. As a rule, California natives typically aren’t climatically welcomed in the rainy Southeast US, but Dichelostemma ida-maia is an exception.
Colors and Textures
Here’s a recent image from JLBG, giving an idea of what’s possible when being thoughtful of textures and colors when planting. Plants include Iris x hollandica ‘Red Ember’, Heuchera ‘Silver Scrolls’, Carex ‘Bonnie and Clyde’, Thelypteris kunthii, and Juniperus chinensis ‘Parsonii’.
Check out our pricks
Spring is unquestionable peak cactus flowering season at JLBG. Although many of you are familiar with our large opuntia (prickly pear) collection, we thought we’d focus on the more diminutive barrel cactus, which you will see if you visit during our spring open house. Keep in mind that most close at night, not reopening until 10am-noon the following day. The photos below are just a tiny sample of the cacti that will be in flower.
Asparagus kissin’ cousin
Ok…raise your hand if you’ve grown Aphyllanthes monspeliensis? This odd, monotypic (only member of the genus) is actually a member of the Asparagus family. Hailing from France south into Northern Africa, Aphyllanthes can be found growing in hot, dry, sandy soils, where it produces an amazing spring show of blue flowers on a 1′ tall clumper. The species name “monspeliensis” is named after Montpellier, France, where it grows naturally. Our plants are thriving in our crevice garden, putting on a superb flower show in mid-April.
Here are images of three of the “next generation” ajuga cultivars, all selections of the Italian Ajuga tenorii. These in-ground photos were all taken at JLBG on April 1. These new ajugas don’t spread wildly or seed around like many of the older, more commonly grown offerings. We think they are pretty darn amazing! The top photo of Ajuga ‘Blueberry Muffin’ represents several plants, planted on 1′ centers. The second image is a single plant of Ajuga ‘Cordial Canary’, and the third is a single plant of Ajuga ‘Petite Parakeet’. These are actually non-staged images, unlike the highly staged, completely unrealistic, manufactured photos you often see in the Dutch-centric catalogs. Hardy from zone 4a to 9b.
Spring crocus are popping all through the garden, and it’s a challenge to photograph them all. We just happened to recently catch Crocus isauricus ‘Spring Beauty’ in full flower. Crocus isauricus (formerly Crocus biflorus ssp. isauricus) is an endemic to Southern Turkey in the region along the Mediterranean Sea.
Iris days of Winter
Here are an assortment of Iris species flowering at JLBG during the last week of February. So many folks only know the bearded iris of later spring, and miss these amazing winter gems. Join us this weekend for our Winter Open Nursery & Garden Days and explore our winter blooming iris.
The first is Iris tuberosa, a winter blooming tuberous iris from Mediterranean Europe. Iris tuberosa is one of the few examples, where a Latinized name change actually results in something that’s easier to pronounce. This gem was formerly known by the tongue twisting name, Hermodactylus tuberosus. Most iris grow from rhizomes, with the tuberous iris being a much smaller and less-known group. We have found these to grow best in part sun. Winter hardiness Zone 7b-10b.
The West-Asian (Caucuses, Iran, Turkey, and Russia) Iris reticulata is also different, in that it grows from a bulb. These are quite easy to grow, and are available commercially in a number of named color forms. Below is Iris reticulata ‘Painted Lady’…looking stunning today. The reticulate (netted) iris grow best in full to part sun. Hardiness is Zone 3-8.
We’ve shown some of the Mediterranean Iris unguicularis recently, but here are a couple more looking particularly nice this week…Iris ‘Front Drive’ (top) and Iris ‘Winter Echos’ below. Hardiness for both is Zone 6b-9b.
Winter Iris Parade
With a mild winter so far at JLBG, our numerous Iris unguicularis clones have been flowering beautifully. First is the clone Iris unguicularis ‘Francis Wolseley’ and then Iris unguicularis ‘Winter Echoes’. Colors in this species ranges from white to light blue to dark purple.
A Rush of Azure
Although we’re celebrating Thanksgiving, Geranium ‘Azure Rush’ is still flowering as though it was mid-spring.
Our favorite fall-flowering legume is looking fabulous now. While most daleas (baptisia cousins) flower in spring and summer, only one that we’ve grown waits until fall to produce its amazing floral show. Dalea bicolor var. argyraea is an easy-to-grow species, found in the dry alkaline sandy soils of Texas and New Mexico. Here at JLBG, it has thrived everywhere it’s been planted…all dry, un-irrigated beds. Native pollinators love it also.
JLBG is full of blazing stars this fall…some seen when looking down in the garden and others looking up in the night sky. Here are couple of recent images, starting with a Texas collection of the widespread native Liatris aspera that’s looking great in the garden. Looking up in the early dawn hours is also pretty spectacular.
When Jupiter drops, this oregano’s golden
A new hybrid that just been amazing in our garden this summer is Origanum ‘Drops of Jupiter’. This Walters Garden introduction is the ultimate edimental…a cross of the gold-leaf culinary oregano, Origanum vulgare, with the flowering Origanum laevigatum. The result is an amazing flowering plant with incredibly fragrant golden foliage. Here is our plant at JLBG putting on quite a show.
Just caught this image of two North American (Northern Mexico) natives snuggled up closely together in the garden. At top is one of the spider lilies, Hymenocallis acutifolia, and wrapped around its ankles is Tradescantia pallida. We truly love Tradescantia pallida as a great combination-enhancing perennial that’s completely winter hardy here in Zone 7b.
A Tasty Treat
Looking and tasting great in the garden now is Origanum ‘Drops of Jupiter’. This amazing creation combines the taste of culinary oregano with oreganos which are grown solely for flowers…the ultimate edimental and a superb plant for pollinators to indulge.
A little purple meatball
We trial several hundred newly developed plants each year, and most never grace the pages of a PDN catalog, either because of performance or a lack of uniqueness. One that has fascinated us is Dahlia ‘Grandalia Burgundy Improved’. With a height and spread of 20″, you’d swear that this dahlia had either been regularly clipped or sprayed with growth regulators, neither of which are the case. The gem has been looking quite incredible in the garden, as it moves into its third year of trial. Obviously, it’s a perennial here in Zone 7b, but would be tender farther north. We’d love to hear your thoughts..
Our oldest clumps of the hardy orchid, Bletilla striata are just amazing…once we learned that these aren’t shade plants. These are under a tall pine and get 1-2 hours of sun.
Sarastro rings a bell
We’ve grown lots of campanulas (bell flower) through the years….109 of them, to be precise. Some are good garden plants, many die, and some even try to take over the garden. After 35 years of trials, the star of the genus is still Campanula ‘Sarastro’. Discovered, named, and introduced by Christian Kress of Austria’s Sarastro Nursery, this superb selection never fails to impress. Here’s our photo this week of it in the sunny gardens here at JLBG, where it reaches 2′ in height and 3′ in width.
Where corydalis fear to tread
We live in a climate of heat and humidity where most of the really cool perennial corydalis fear to tread. One outstanding selection that has thrived here for the last quarter century is a discovery from our friend, Dan Hinkley, that he named and introduced as Corydalis leucanthema ‘Silver Spectre’.
Part of the secret to its survival is that it has the good sense to sleep through the summer months, emerging in late fall and grow through the winter months. Here’s a photo in the garden this week in full flower. We’ve found it very adaptable and easy to grow, although rich, slight moist compost is ideal. We haven’t offered this in a while, but if you think we should put it back in production, that wouldn’t take much arm-twisting.
Another cool corydalis that we love is one that came to us as a hitchhiker (we think), but one that we gladly adopted is Corydalis speciosa. Thanks to corydalis guru Magnus LIden for the identification. The winter foliage emerges heavily ruffled and then flattens, with flowering starting in late winter. I think this may make it’s way into propagation.
Epimediums on Parade in the Garden
What an incredible week for epimediums here at Juniper Level. The first photo is our introduction, Epimedium ‘Songbirds‘…an insanely heavily flowered yellow selection.
Epimedium wushanense ‘Starlite‘ is our selection of the amazing Chinese species, which boasts large terminal inflorescences on a plant that approaches 2’ tall.
Epimedium zhushanense is another incredible Chinese species with large bicolor, spider-like flowers. We think these are truly stunning in the woodland garden.
