Looking good this week is Nierembergia ‘Starry Eyes’. We have special memories watching our friend Carl Schoenfeld collect cuttings of this on our 2002 botanizing trip to Argentina. While it’s only reliably winter hardy to Zone 8, it’s a flowering machine during the summer. Here it is growing in our new crevice planting near our Open House welcome tent.
We had failed miserably at keeping the true blue-flowered forget-me-nots, Myosotis, alive in our heat and humidity until our friend and gardening legend, Pam Harper shared this amazing heat tolerant form with us in 1994. We subsequently named it M. ‘Southern Blues’. It has thrived as both a marginal aquatic and in regular garden soils, where it makes a superb non-weedy, groundcover. In over 25 years, we’ve never seen a single seedling. Here it is in the gardens at JLBG this week.
The non-weedy Ajuga ‘Blueberry Muffin’ from the breeders at Terra Nova has really put on quite a show at JLBG this spring. We love the non-seeding and slow spreading traits…not to mention the amazing floral show.
Our baptisia introductions are looking absolutely fabulous this week. Here are a few in case you missed the first weekend of our open house. Baptisia ‘Aspriing’ (top) with its long spikes of lavender blue flowers, followed by the incredibly dense flowering Baptisia ‘Blonde Bombshell’. Next is our Baptisia ‘Cherry Pie’, which brings a new color to the genus, and ending with Baptisia minor ‘Blue Bonnet’ with it’s enormous blue flowers. Baptisia are a North American genus of long-lived perennials that can grow equally as well with cactus or as a marginal aquatic…as long as they have full sun.
Earlier we posted photos of wild collected Amsonia tabernaemontana, so here is a closely related species that’s been hopelessly mixed Amsonia tabernaemontana, thanks to mothball-sniffing herbarium botanists. Amsonia glaberrima is a gulf coast species that’s actually quite different…smooth leaves for a start, and different habit and flowering time. Here is our garden selection grown from a seed collection in east Texas. This is a truly exceptional plant, so I expect we’ll get our propagation staff to tackle this after flowering.
Just snapped this photo of the amazing Amsonia ‘Storm Cloud’ in the garden. This was a 2011 discovery in Central Alabama on a botanizing trip with Hans Hansen.
Amsonia (aka: bluestar) are one of the best temperate genera (18 species) of blue-flowered perennials for the spring garden. We’ve offered quite a few different species and selections through the years, rotating them in and out as propagation successes allow and as sales dictate. All but two of the species, (Amsonia orientalis from Europe and Amsonia elliptica from Asia) are North American natives. Most are extremely drought tolerant, while others like Amsonia rigida and Amsonia tabernaemontana can tolerate very wet soils.
Amsonia montana is a commonly grown plant of mystery, having just appeared in horticulture, but never been documented from a wild population. A few of the amsonia species have flowers so pale blue that they appear white in the garden with only a hint of blue on the flower corolla. Amsonia are quite promiscuous in the garden, so if you grow more than one species nearby, you will have hybrids from seed. We hope you’ll explore this amazing genus of perennials.
Flowering now at Juniper Level is one of my all-time favorite perennials…Campanula porscharkyana ‘Camgood‘. This amazing perennial flowers as well in full sun as in light shade. Best of all, it’s easy to grow and doesn’t run like many bellflowers. I can’t imagine gardening without it. Hardiness is Zone 4-7 at least.
The baptisias are looking fabulous in the garden now. Here’s Baptisia ‘Blueberry Sundae’, a hybrid from Hans Hansen of Walters Gardens. Baptisias are as drought tolerant as catus, but can also grow equally well streamside with their roots in standing water.
If you want a more vertical accent, Here is our Baptisia ‘Blue Towers’ in the garden today. If you have full sun, we hope you’ll add these great native plant selections to your garden.
The dwarf native woodland iris, Iris cristata are in flower here today. Iris ‘Montrose White’ was introduced by Montrose Gardens in NC. Iris cristata is native in shade, but flowers much better when given a couple of hours of sun.
Iris cristata ‘Powder Blue Giant’ is incredibly floriferous in the garden today. These spring flowering groundcovers are just delightful.
