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.
Hemerocallis ‘Autumn Daffodil’ was introduced in 1949, but remains one of the most incredible daylilies we grow here at JLBG. The 3′ tall, branched, sturdy, upright stems are topped with an abundance of amazing highly fragrant yellow flowers starting in July.
If you visit JLBG, it’s hard to miss that we like combinations of purple and gold. Here is a favorite summer combo, planted across from the crevice garden, where we use Rudbeckia speciosa as a foot warmer for Calycanthus ‘Burgundy Spice’…a fun combo using two North American natives.
If you’ve got a spot for big, bold, and bodacious in your garden, it’s hard to think of a better choice than Verbesina olsenii. This giant North American (Northern Mexico) native frostweed would be great even if it didn’t flower, which it does in mid-October with giant yellow corymbs that smell like tootsie rolls.
Here’s our reference stock blocks of zephyranthes (rain lilies). Within 3-4 days after a rain, the beds are ablaze with what the late rain lily breeder, Fadjar Marta, called a floral blitz. We concur.
Lycoris (surprise or hurricane lillies) season has begun in earnest. We’ve already had 97 diffrerent clones to flower and the season is young. In a typical year, we usually flower between 300 and 400 different selected clones. Here are a few that have looked good so far. The top three are spring-leaf varieties, and as such, should be winter hardy in Zone 5. The bottom two are fall-leaf varieties and are winter hardy from Zone 7b south.
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.
We expect most everyone has grown a hibiscus at one time or another, either tropical or hardy. How many of you have tried the Asian Hibiscus hamabo? This fascinating 8-10′ tall evergreen shrub has thrived in our trials since 2018, and is just now flowering at JLBG for the first time. We had always considered this species tropical, so we were thrilled to hear that it survived as a die back at the SFASU Arboretum in Texas after this springs’ arctic blast of -4F. Dr. Dave Creech at SFASU tells me that it remains evergreen down to 10 degrees F. Has anyone else had experience with growing this outdoors in a cold winter climate?
One of the June joys at JLBG is flowering season for Lilium x sulphurgale ‘Vico Gold’. We have grown to love the summer-flowering liliies for their ability to leap from the ground amongst a crowded landscape to provide a burst of color and fragrance during the heat of summer. Lilium ‘Vico Gold’ is not just a star, but it has a great back story. Alabama gardener Wade Mahlke shared this with us in 2013, from his trip decades earlier to the Switzerland garden of the now deceased Sir Peter Smithers. For those who haven’t read Sir Peter’s books, his career was as a spy in the British Secret Service, working for Ian Fleming. James Bond fans will certainly recognize the name. After his retirement, Smithers served in British Parliament before retiring to Switzerland, where he indulged his passion for gardening and plant breeding until his death in 2006 at age 93. Lilium ‘Vico Gold’ is his introduction of a hybrid of Lilium sulphureum and Lilium regale…a superb introduction that we’ve “bonded” with in the garden. It looks like we may be able to finally make it available through Plant Delights next spring.
Echinacea ‘Big Kahuna’ has turned into a wonderful beast in the garden. Here is our clump of this super vigorous selection this week as it enters its third year in the gardens at JLBG with no sign of slowing down. The fragrance is also amazing, as are the number of bees it attracts.
