Proud Pedicles

Flowering this week at JLBG is the little-known, but marvelous Liriope longipedicellata ‘Grape Fizz’, thanks to the exploits of plantsman Darrell Probst. We find this tightly clumping species much more interesting than the more formal Liriope muscari or the weedy, spreading Liriope spicata, and will tolerate full sun to shade. By the way, pedicles are stalk-like structures connecting one plant part to another….in this case the flower stalk to the flowers, hence the specific epithet longipedicellata (long pedicles).

Starry Eyes

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.

Upside down in Dry Shade

At our home, we have a very wide overhang which never sees any moisture, so we were looking for plants that would stay low, ideally evergreen, and would tolerate seriously dry shade. The answer was Echeveria ‘Topsy Turvy’. These patches of the Northern Mexican succulent, with blue-green foliage, have absolutely thrived here. While they probably wouldn’t be happy in deep shade, they love this high canopy with good light, but no sun. These were planted in 2018. We’d rate these as Zone 7b/8a if kept dry in winter.

Southern Blues

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.

Ajuga madness

We’re trialing quite a few of the new colored-foliage, non-invasive ajugas, and are quite excited so far. Here is one of several that we really like, Ajuga ‘Parrot Paradise’ in the garden. These ajugas open up a wealth of color combination possibilities for garden designers. Hopefully, you’ll see this gracing a Plant Delights catalog in a few months.

My ginger…your foliage is…wrong

I grew up as a child spending most of my time botanizing the woods from a ridiculously early age. One of the native plants I’ve known since my earliest adventures is Asarum arifolium, which was the most common wild ginger in our region. Over the last 60 years, I’ve undoubtedly seen tens of thousands of this species.

Asarum arifolium typical form in flower

I was fascinated by the variability in the amount of silver in the leaves, the contrast in the leaf pigmentation, the propensity to clump tightly or run, along with some slight variations in flower color and size. Below is a form that makes a particularly tight clump with good contrasting leaf markings. Despite the occasional solid green leaf forms, the one constant has always been the green leaf veins in between the silver blotching….until…

Asarum arifolium nice form of typical pattern

untill I found the oddball below in the woods north of Mobile, Alabama. In the middle of a patch of normal plants was one single individual with reversed leaf patterns…the leaves have a green base with silver veins. I certainly know the pattern, which is typical of several other native asarum species (minus, heterophyllum, lewisii, harperi, shuttleworthii, etc.), but this pattern simply isn’t allowed in Asarum arifolium. We watched impatiently as our plant first flowered, thinking it must be some odd hybrid, but the flowers told a different story…pure Asarum arifolium. We even grew a crop from seed to discover that 50% of the offspring had this same reverse pattern. As we chatted with other botanists about our find, we’ve discovered two other folks who have also found similar individuals, so these “off the bell curve” forms are out there, albeit quite rare.

Hungry for a Blueberry Muffin?

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.

Living Mulch

We’re always looking for more “green mulch” plants, which cover the ground, reducing weed pressure, while not choking out desirable plants. One such plant we feel should be more widely grown is Erigeron pulchellus. This amazing perennial is native to every state east of the Mississippi River. So, why isn’t it grown in every garden? Inquiring minds want to know. The rosettes lay flat on the ground, but are topped right now with short 8″ spikes of blush pink daisies. Our photo from the garden this week is the clone Erigeron pulchellus ‘Lynnhaven Carpet’. Erigeron pulchellus is easy to grow in average soils in light shade to part sun.

Safe Landing on Planet Zork

There are a number of very exciting new ajugas to hit the market in the last few years, but one of our favorites has a longer history. Ajuga reptans ‘Planet Zork’, which we first acquired in 2004, is a non-flowering, crinkled-leaf sport of Ajuga ‘Burgundy Glow’. It was brought to the US from Japan, and later named and introduced here by plantsman Barry Yinger. We first grew Ajuga ‘Planet Zork’ in light shade, but it really showed its true colors when we transplanted it into full sun and moist soils. It’s parent, Ajuga ‘Burgundy Glow’ is ungrowable in our climate, rotting at the sign of rain during our hot, humid summers. Unlike many ajugas, this is a tight clumper that doesn’t seed around…an ideal groundcover.

Oh Cezanne, Don’t You Cry For Me

Ok, the spelling of “Susanna” is slightly different, but don’t let that deter you from growing one of the greatest groundcover clematis that we’ve ever grown. Yes, that’s right…no mailbox post or staking required. We’ve been growing this amazing, compact clematis as a groundcover for years and it is truly superb. Here it is in the garden this spring, but it will also continue to flower into summer. What’s not to love about Cezanne!
