Here’s a fun combination this week with Gladiolus byzantinus ‘Cruentus’ mingling with Baptisia alba. The European native glads, such as this and Gladiolus italicus are the earliest gladiolus to flower in our climate.
Allium ‘Ostara’ is a new bulbous ornamental onion from a cross of the lovely, but difficult to grow (in the southeast US) Allium karataviense and Allium atropurpureum. We’re growing this in our crevice garden, which is working well…so far. We’re hoping the genes from Allium atropurpureum will make this more growable.
Although narcissus are far from my favorite bulb…mostly due the terribly obtrusive foliage, we have grown quite a few species and cultivars through the years. My love is really for the smaller plants, which usually come with smaller foliage. One cultivar that has stood out through the years is Narcissus ‘Hawera’. Here is our oldest clump, planted in 1997, and despite not being regularly divided, it still puts on a fabulous show every year. Our plants are from our dear friends Brent and Becky Heath at Brent and Becky’s Bulbs.
Every year in late winter/early spring, one of the woody showstoppers at JLBG is the Afghan bush cherry, Prunus jacquemontii. This year was no exception as this stunning deciduous shrub is putting on an amazing show. Our twelve-year old plant is now 4′ tall x 6′ wide.
Flowering this week is our selection of Magnolia floribunda ‘Bridal Bouquet’. When we visited Yunnan, China in 1996, we were able to return with three seed of Magnolia floribunda, a species which seemed completely absent from American horticulture. The resulting seedlings were planted into the garden, where two promptly died during the first winter. Thankfully, one survived and is still thriving today 25 years later.
Magnolia floribunda ‘Bridal Bouquet’ forms an upright, somewhat open evergreen that sometimes starts flowering as early as mid-January. This year, thanks to our consistent cold, it waited until early March to start its floral show. The flowers have a distinctive and fascinating fragrance that we find unique among our magnolia collection. We have shared cuttings with several woody plant nurseries and donated plants to a few rare plant auctions in the hopes of getting this more widely cultivated.
Flowering this week is the aptly named Adonis amurensis ‘Sandanzaki’. This tiny spring ephemeral, whose genus is named after the God of Beauty and Desire, needs to be in a special place so it won’t get lost in the garden. The exquisite floral pattern of this Japanese selection is so amazing.
When we finally discovered that sea kale (Crambe maritima) is indeed growable in our hot, humid climate, we’ve planted it all around. It’s also been rewarding that people have actually purchased it to try for themselves. Frankly, I’d grow sea kale for the ornamental value alone…a perennial with blue waxy foliage and an incredible show of white flowers in spring! Then, there’s the edibility, both cooked and raw. Also, for us, unlike other cabbages and kale, it has been virtually untouched by the pesky cabbage loopers.
Here is a photo of sea kale in our crevice garden this April, growing in a soil mix that’s 50% gravel, with no summer irrigation. Read my lips, I mean text…full baking sun and no irrigation after establishment. We recommend you never let your plants read the repetitive on-line sites that all tout that it only grows in cool, moist, climates…hooey!
