Sunrise over Maui

Here’s a recent image of the amazing Colocasia esculenta ‘Maui Sunrise’, still looking great in late October! Moist, rich soils and full sun are the key for your plants to look this spectacular! Winter hardiness is Zone 7b and warmer.

It ain’t worth a thing if it ain’t got that bling!

Apologies for commandeering the famed Duke Ellington line, but it seems appropriate for the new Colocasia ‘Waikiki’.

Colocasia esculenta ‘Waikiki’

When we first met Hawaii’s John Cho in 2003, we knew some special elephant ears would be the result of our collaboration, but it was hard to imagine something like the seriously tricked-out Colocasia ‘Waikiki’. Almost every year, John, who has now retired, but is still actively breeding elephant ears, travels to JLBG to evaluate his new hybrids at our in-ground trials and make future introduction decisions. There are some seriously amazing new selections starting down the introduction pipeline.

Colocasia ‘Waikiki’ will be released from Plant Delights Nursery on January 1, so if you like this, mark you calendars and stay tuned to the website.

Sex for the Centuries

Since we are limited in the number of hardy century plant species, our only option for more agave diversity in the garden is to create it by crossing existing hardy species together. Here are a few of our recent successes.

Agave x amourifolia is a Plant Delights/JLBG creation from a cross we made in 2016 that combined the genes of three century plants, Agave ovatifolia, Agave lophantha, and Agave x pseudoferox ‘Logan Calhoun’. Our size estimates were that the offspring would mature at 3′ tall x 5′ wide. Here is one of our garden specimens photographed this week, which has already reached 2′ tall x 3′ wide.

Agave x amourifolia

Below is Agave x ovox, a 2017 cross of the two giants, Agave ovatifolia and Agave x pseudoferox ‘Bellville’. We expect this to get huge…perhaps 5′ tall x 10′ wide.

Agave x ovox ‘Large Ox’

Below is Agave x protifolia is a 2016 Mike Papay cross of Agave x protamericana x Agave ovatifolia. We also expect this to get quite massive.

Below is Agave x ovatispina ‘Blue Arrows’, a 2016 Mike Papay cross of Agave ovatifolia x Agave flexispina. We would have expected this to be a mature size, but it’s achieved this in only 5 years, so we think we’re seeing some serious hybrid vigor.

Agave x ovatispina ‘Blue Arrows’

Below is Agave x ocareginae, our 2016 cross of Agave ovatifolia x Agave victoriae-reginae. Most likely, this elegant small grower will never offset.

Below is Agave x schuphantha, a 2015 Mike Papay cross involving three century plant species, Agave schidigera, Agave lophantha, and Agave lechuguilla. It’s formed a beautiful, symmentrical rosette, which should be getting close to mature size.

Vilmorin’s Oak

Outside of the nerdy members of the International Oak Society, few gardeners have ever heard of Quercus x vilmoriniana. This spectacular oak is a hybrid between the Asian Quercus dentata and the European Quercus petraea. Quercus x vilmoriniana has been known in European gardens since 1894, but is rarely seen in US gardens. The hybrid is named for the late French botanist Maurice Leveque de Vilmorin.

Our 20′ tall specimen at JLBG was planted in 2012 and has developed not only superb foliage, but splendid deeply-fissured bark. There is an old specimen at Cornell in NY, so it shows good cold tolerance in addition to loving our hot, sweaty summers. We have sown acorns from our plant, and if they grow, we will make this available though the Southeastern Plant Symposium Rare Plant Auction in June.

Dalea…not Dahlia

Our favorite fall-flowering legume is looking fabulous now. While most daleas (baptisia cousins) flower in spring and summer, only one that we’ve grown waits until fall to produce its amazing floral show. Dalea bicolor var. argyraea is an easy-to-grow species, found in the dry alkaline sandy soils of Texas and New Mexico. Here at JLBG, it has thrived everywhere it’s been planted…all dry, un-irrigated beds. Native pollinators love it also.

Sleeping Beauty

We’ve written before about plants that get much larger than we are told in the catalog descriptions. Well, our latest example is Buddleia ‘Sleeping Beauty’, a hybrid of Buddleia lindleyana and Buddleia davidii. In two short years in the garden, it became a monster, reaching a 7′ tall x 12′ wide with no sign of slowing down. It was quite lovely and floriferous, but has now become a welcome member of our compost pile…sigh

Sharon’s Rose

Our plants of Hibiscus syriacus ‘Capra’ are worthy of a photo share this week. This is the best of the variegated leaf rose of sharon’s we’ve trialed, and so far, it been sterile, which is a requirement for any rose of sharon to remain in our garden.
