Here are a few of our favorite hardy Hippeastrums flowering in the garden this week. Many gardeners incorrectly know these South American bulbs as Amaryllis, which is an entirely different genus of two species of South African bulbs, which do not thrive here. Hardiness is Zone 7b-10b.

I weep for Alliums–of all sizes
Flowering in the garden in late April were an array of amazing Alliums. The top image is Allium ‘Ambassador’, a hybrid of Allium stipitatum x giganteum. This sterile gem is a 2005 release from the breeders at Hollands’ Fa. A. Langedijk.
Below that is the smaller Allium drummondii, a native to the prairies from South Dakota to Texas.
High on Hawera
Looking absolutely lovely this week is one of our patches of the late-flowering Narcissus ‘Hawera’. We love these narrow-foliage types which remain looking good after the flowers have faded. Unlike many narcissus we grow, this one also doesn’t require regular dividing to continue to flower well. Interestingly, this gem has been in commerce since at least 1928.
Flowering for the last week in the garden is the lovely winter iris, Iris reticulata ‘Painted Lady’. Iris reticulata is unusual in that it has bulbs instead of rhizomes. In the wild, it calls home the dry regions from Turkey to Iran. These spring ephemeral iris go to sleep for the year by late spring/early summer. Hardiness is Zone 5a-8b, at least.
Have you caught Galanthophila?
Galanthophila, an obsession with snowdrops of the genus Galanthus, is spreading almost as fast as COVID did through both Europe and North America. While we love and value galanthus for their flowering in the winter garden, we’ve yet to take the plunge into full-fledged galanthophilia, which results in people sacrificing meals to have the latest new name in snowdrops for their garden. For serious galanthophiles, it’s not unusual to pay from $100 to $10,000 to have the latest, greatest selections. Although there isn’t a cure, the 12-step program seems to be able to help some gardeners keep this addiction in remission.
Here are a couple of specimens that are looking quite nice in the garden this week. Galanthus ‘Viridapice’ has been around since the 1920s, while Galanthus ‘Beth Chatto’ dates from the 1960s. Despite their advanced age, these gems have stood the test of time. All galanthus will go dormant in late spring.
We are always interested in checking out the offspring, when plants in the garden have unexpected romantic rendezvous with their distant cousins…often when we least expect it. We have found arums tend to be quite promiscuous in the garden. While most offspring go to the great compost pile in the sky, a few are worthy of adoption and naming.
Below is our selection of a cross of Arum dioscorides x Arum italicum that we named Arum ‘Love Child’. While the foliage resembles typical Arum italicum, the spring-borne flowers show great influence of Arum dioscorides with the purple spotting inside the spathe. It’s our hope that Plant Delights will have a first crop of this new hybrid to share in the 2023 catalog.
Hi Ida Maia
Looking great in the crevice garden this month is the Pacific Northwest native, Dichelostemma ida-maia This odd little bulb is a member of the Asparagus family…so that makes it as cousin to agaves, hostas, and asparagus. In the wild, it is only found in coastal meadows and into forest edges and partial woodland openings in Northern California and Southern Oregon. As a rule, California natives typically aren’t climatically welcomed in the rainy Southeast US, but Dichelostemma ida-maia is an exception.
Atamasca or Atamasco?
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.
Rolfing in the Garden
Starting in late winter, the amazing blue-flowered South American Ipheion ‘Rolf Fiedler’ begins its stunning floral show in the garden. This rare native, which has only been found on the top of two hills in Uruguay, has yet to be formally assigned a confirmed species name, although some botanist believe it to be Ipheion peregrinans. Growing much lower to the ground than it’s South American cousin, Ipheion uniflorum, this un-named species spreads nicely in dry soils, either in full or part sun.
If you’re taxonomically inclined, the entire Genus ipheion has been bounced back and forth between a series of other genera for the last century, so we’re waiting for the taxonomic dust to settle before changing tags. Ipheion has previously been included in a number of other genera including Beauverdia, Brodiaea, Hookera, Leucocoryne, Milla, Nothoscordum, Tristagma, and Triteleia. Not only is the genus in question, but ipheion has now been moved from the onion family (Alliaceae), where it resided for a century to the amaryllis family (Amaryllidaceae).
For now, we’re just enjoying “rolfing” in the garden.
Fritters in the Garden
We’ve made a regular habit of killing fritillarias (the bulb…not the fried food) in the garden, especially those ungrowable brightly-colored species like Fritillaria imperialis that tantalizingly appear each fall in the major bulb catalogs.
Although it lacks the bling of it’s showier cousins, the species that is reliable for us in the garden is Fritillaria thunbergii. This native of Kazakhstan has naturalized in both western China and Japan, where it has been used medicinally for almost 1,000 years as a treatment for respiratory ills. There is still some debate among botanists whether some of the Chinese population might actually be native as well.
In the garden, Frittilaria thunbergii emerges in February, and is full flower at 2-3′ in height by early March. As with most spring ephemerals, it has gone to sleep by early May. Light shade or part sun seems to suit it fine. Hardiness is at least Zone 7a-8b.
Intermingling in the Garden
We love intermingling plants, often planting more than one type in the same space, where their growth habits allow them to comfortably co-exist. Here is a three year-old planting where we used ‘Gold Queen’ Hyacinth among a patch of our North American native groundcover juniper, Juniperus horizontalis ‘Bar Harbor’. Despite what many folks seem to think, there are no laws that plants in the garden can’t touch each other, so how about some more hand-holding in the garden.
Spring crocus are popping all through the garden, and it’s a challenge to photograph them all. We just happened to recently catch Crocus isauricus ‘Spring Beauty’ in full flower. Crocus isauricus (formerly Crocus biflorus ssp. isauricus) is an endemic to Southern Turkey in the region along the Mediterranean Sea.
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.
Staring at Ostara
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.
A Dilly of a Daffodil
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.
A little daffy
We absolutely adore the miniature winter flowering daffodils. Here is the tongue-twisting Narcissus romieuxii ssp. albidus var. zaianicus flowering in the garden. These wild species narcissus flower long before most other narcissus have thought about breaking ground.
