The parade of Lycoris (surprise lilies) continue into their third consecutive month as we move through September. The key for a succession of flowers is having a large number of cultivars. So far at JLBG, we have flowered 300 different cultivars this summer. Here are a few recent ones. The varieties which form fall foliage are winter hardy in Zone 7a/b and south. Those whose foliage emerges in late winter/early spring are winter hardy in Zones 4/5.
We cannot think of any plant that draws more hummingbirds than the hardy upright sinningias. Most of these are Sinningia selovii hybrids that come in a range of colors from yellow to orange to red. We have them ringing our full sun patio, which results in a non-stop show of hummingbirds.
Every year around July 4, we celebrate with our own horticultural fireworks show as the South African Scadoxus multiflorus ssp. katherine bursts into flower. Here are our plants at JLBG this week. This amazing bulb requires light shade to grow and thrive. Anyone whose woodland gardens suffers from the summer doldrums, would do well to include Katherine. Hardiness Zone 7b-10.
Flowering at our exit drive this week is the beautiful Canna ‘Red Futurity’…a superb purple-foliaged canna lily. Learn more about growing canna lilies in your garden.
We saw this amazingly colored buckeye (Aesculus pavia) on a recent visit to the NC Arboretum in Asheville. I’ve seen countless individuals of this species, both in the wild and in gardens and have never seen a color like this. We have encouraged them to get this grafted and introduced.
Back in 2009, the since deceased Delaware Valley plantsman, Jim McClements, shared a may apple hybrid he’d created by crossing the US native Podophyllum peltatum with the Chinese native Podophyllum pleianthum. The offspring was named Podophyllum x inexpectum ‘Ruby Ruth’ (after his second wife). Our plant spent years in a much too dry a garden location until we relocated it to a bog setting alongside pitcher plants. Finally this year, we got our first flowers…a lovely bright red. Now the dilemma is that some Chinese researchers consider their may apple not to be a podophllum at all, but instead a sister genus, Dysosma. If we buy into that theory, then our plant becomes a bigeneric hybrid that will need a new nothogeneric name, either x Dysophyllum or x Podososma. After growing most of the growable species, I’m having a hard time supporting the idea of two separate genera, but we’ll see.
Our 3-year old clump of Abutilon megapotamicum (flowering maple) is looking particularly splendid this week. Planted in full sun and compost amended soil, it has reached 6′ in height and 10′ in width. When grown in part sun or light shade, both flower production and size is reduced. In mild winters like we’ve had recently, Abutilon megapotamicum will flower for nine months, but in winters where our low temperatures drop into the single digits, it will die back to the ground and re-sprout in spring. Despite the common name, abutilon is not a maple, but instead is a member of the hibiscus family. I can’t imagine a garden without this amazing plant.
Looking truly superb this spring is the South African ice plant, Delosperma dyeri in the crevice garden. We can’t grow this in typical soil due to our high rainfall, but in our crevice garden where gravel is the main planting media, it performs like a champ.
Silene ‘Jackson Valentine‘ is one of those plants you just can’t help but photograph. In fact, I seem to wind up taking a new picture each day during its spring flowering season. Here it is in the garden yesterday in all it’s radiance. This incredible native thrives in part sun with good drainage. It just doesn’t get much better than this.
