With September temperatures reaching 100 degrees F in Raleigh, is it any wonder we’re thinking about snow? Looking lovely after a recent rain is the rain lily, Zephyranthes ‘Summer Snow’. We grow a huge number of rain lilies, but none out flower our 2014 introduction of a hybrid between Zephyranthes candida and Zephyranthes citrina. This started its life as 5 original bulbs.
Most folks are familiar with the mysterious Howard Hughes, but we have an equally mysterious “Howard” in horticulture. Flowering well now in the gardens at JLBG is the amazing xHowardara ‘Riley Kate’. This fascinating hybrid was created by Texas bulb guru, Dr. Dave Lehmiller, who crossed a Hippeastrum (amaryllis) and a Sprekelia (Aztec lily), and a Zephyranthes (rain lily). Lehmiller’s cross resulted in five different named cultivars and were subsequently named after the late Texas bulb guru, Dr. Thad Howard.
Creating a trigeneric hybrid is beyond rare, since it isn’t supposed to happen according to the rules of botany. Consequently, the introduction of the first clone sent taxonomists into a frenzy trying to publish new research to re-combine the genera involved into a single genus, so as not to have their rules violated. xHowardara’s occasionally flower for us in mid-summer, but peak flowering is always in September and October in our climate. Hardiness is Zone 7b – 9b, at least.
Ever since I was a small kid, I’ve observed Zephyranthes atamasco (atamasco lily) in the wild, where they grow in swampy wooded lowlands. Atamasco lily is also one of many great nomenclatural muddles with regard to it’s correct spelling. When it was first named by Linneaus, back in 1753, it was assigned to genus amaryllis, so the specific epithet was spelled “atamasca”.
In his later work, Linneaus changed the spelling to “atamasco”, which corresponded to the Native American name for the bulb. It remained spelled with an “o” even after it was moved into the genus Zephyranthes in 1821. The problem is that, according to International Nomenclatural rules, the original spelling must take precedent. So, Zephyranthes atamasca is correct. Except…there is an exemption for name conservation, when correcting the name will cause confusion or economic harm. There is currently a well-supported move underfoot to conserve the long-used spelling “atamasco”. And you thought nomenclature was boring!
I’ve long marveled at the diversity within the species, and as an adult have been fortunate to be able to collect offset bulbs from some of the special forms I’ve found.
The top image is a very compact form that we’ve named Zephyranthes ”Milk Goblet’. Below that is one of our larger flowered forms from Alabama that we named Zephyranthes ‘Hugo’. Hugo has 5″ wide flowers in a species where 2.5-3″ wide is typical. Both of these are in full flower now at JLBG.
We are fascinated with the wonderful genus zephyranthes (rain lilies). Zephyranthes are unobtrusive, summer-flowering bulbs that can fit in any garden, with a flower color ranging from yellow to white to pink. The great thing about zephyranthes is the lack of large foliage that often accompanies many other spring-flowering bulbs, so site them in the front of the border, or in a rock garden to be best appreciated.
Zephyranthes are one of our specialty collections at Juniper Level Botanic Garden, with 25 species and 257 unique clones. Here are a few of the zephyranthes blooming this morning in our alpine berm. You can view our entire zephyranthes photo gallery here.
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.
Zephyranthes has the common name rain lily for a good reason…it has the charming habit of sending up new blooms after a summer rain (it would make an excellent rain garden plant). Zephyranthes (rain lilies) are small perennial bulbs that need to be sited in the front of the border, or in a rock garden to be appreciated.
With an abundance of days in the mid 90’s in July, August has started with an abundance of rain, from hurricane Isaias to afternoon thunderstorms. And the rain lilies are loving it! Here are some of our rain lily collection in our outdoor production beds. Let us know which ones appeal to you and we will try to get them in future catalog!
One of the rewards of making it through the dog days of summer, as well as renewed hope for fall’s arrival, are the numerous late summer and fall blooming bulbs that offer pop-up-blooms in the garden.
These late summer/fall blooming bulbs include lycoris, rhodophiala,
habranthus and zephyranthes. Here are a few of the beauties blooming in the garden yesterday.
Join us Saturday, September 14, 2019 for our Fall Open Nursery & Garden Days. Meet our taxonomist, Zac Hill, at the welcome tent at 10am for a tour through the gardens exploring fall blooming bulbs.
