Testing the limits... and finding them: 2014-2015 losers

August 2015: no more windmill palms

I've always been interested in testing the limits of marginally hardy plants, plants that are new to cultivation, and plants whose hardiness is otherwise unknown.  For better or for worse, my last two winters have been very good ones for testing hardiness!  The low temperature in my back yard in Washington, DC (zone 7a) during both winters was about 5 degrees (-15° C), my area's coldest temperatures in 20 years.  Despite the similar low temperatures, the two winters were very different in terms of wind, snow cover, and timing and duration of the cold.  Several plants that survived the first of the two winters didn't make it through the second; in some cases I think they were weakened going into the second winter, but I also think the ground froze more deeply, doing more damage to otherwise healthy plants.

Tooting my own horn: Seemannia 'Little Red'

Seemannia 'Little Red' in my Washington, DC garden

I haven't worked with gesneriads for a couple of years so I got a bit of a thrill this morning when I found one of my own hybrids, Seemannia 'Little Red', listed for sale in the Fall 2015 catalog of Plant Delights Nursery.  Plant Delights is considered one of the premier nurseries for rare and unusual plants, so having one of my plants listed is a pretty big deal.

Throwback Thursday: Florida 2005

Strangler fig, Naples, January 2005

It's hard to believe I've been vacationing in Ft. Lauderdale, Florida for 10 years.  In 2005, Dan and I decided to spend a day there before traveling to Sarasota, where I was scheduled to give a talk at Marie Selby Botanical Gardens.  I hadn't been to Florida since I was a kid, and never to south Florida at all, so I arranged a whirlwind tour that started in Ft. Lauderdale, stopping in South Beach on our way to a tour of Fairchild Tropical Botanical Garden in Miami, driving across the state to visit my parents and aunt in Naples, up to Sarasota and Selby, then back to Naples for more family time and finally flying out of Ft. Myers, all in the space of 5 days.  In retrospect it was insane, but we enjoyed that trip immensely.  Here are a few more photos from that trip (although oddly enough, I have none from Ft. Lauderdale!).

Garden bloggers bloom day: November 2014

Despite a few evening clouds, it was cold and clear last night in Washington, DC and we finally got our first good freeze of the season.  I've had a couple of very light frosts already, when overnight lows were in the 30's, but without any damage to my plants.  Last night was the first time it went down to the freezing point, 32 degrees F (0 C), or perhaps slightly lower.  When I went out this morning to survey the damage the first thing I noticed was the sickly sweet smell of frostbitten vegetation.  That's the part I always forget.

Garden Bloggers Bloom Day: September 2014

Seemannia hybrid

Bit by bit, the garden is recovering from a brutal winter.  It may not look like much from above: there are a couple of empty spaces where palms used to grow, the hardy banana (Musa basjoo) hasn't grown nearly as big as it did last year (see Everybody loves my big banana), and the figs were killed to the ground and are coming back from the roots, but hidden underneath all that foliage are some plants that are just now hitting their peak.

Clerodendrum bungei

For Throwback Thursday, I'm looking back at some of the photos I've taken over the years.  I've been using Flickr to post and share my photos online since September 2007 and I've just passed 400,000 views on my DC Tropics Flickr account.  That's a pretty random milestone and I should note that I only checked it after a friend and fellow Flickr user announced that he had reached 10 million views.

So far I've posted almost 3,800 photos.  Many Flickr users have posted far more photos than that (my friend has over 62,000 photos posted) but like many of those users I'm not very happy with Flickr lately (suffice to say their ugly and clunky "new and improved" version sucks) but there are still some things I like about Flickr.

×Gloximannia 'She's Dancing'

 

What the heck is a ×Gloximannia?  (The "×" or multiplication sign, indicating an intergeneric hybrid, is not pronounced.)  In a previous blog post I discussed the gesneriad genus Seemannia, a close relative of Gloxinia.  Although these two genera look very different, they are closely enough related that their respective species can be easily crossed to produce viable hybrids.  And what do you get if you cross the two genera?  The nothogenus (hybrid genus) ×Gloximannia, of course.  To the best of my knowledge, only Gloxinia perennis has been used from that genus and the hybrids tend to take after this parent.  Neither of the other two species--Gloxinia erinoides and Gloxinia xanthophylla--have yet been crossed with any Seemannia species; it would be very interesting to see how such hybrids would turn out.

Seemannia: a gesneriad with commercial potential

Seemannia 'Little Red'

Seemannia is a small South American genus in the same family (Gesneriaceae) as african violets and gloxinias (and until recently Seemannia was included in the genus Gloxinia).  The species and a few hybrids (primarily my own) are in very limited cultivation, but I believe that with a bit of tweaking they may have some commercial potential as bedding and container plants.  (Photo: Seemannia 'Little Red', one of my own hybrids)

Then and Now (part 1)

This is what the back yard looked like from our back door when my partner (now husband!) Dan and I purchased the property in December 2000.  I knew that gardening on a slope, especially one with a northern exposure, would be a challenge but we had looked at over a hundred houses all over the city; this was one of the few that had both a decent-sized yard (by urban standards!) and off-street parking (that's our garage at the top of the hill), was in a good neighborhood, and (barely) within our price range.

This is how the garden looked that first spring, when I discovered all the uninspired plants the previous owners had planted (but you can see from pots in the foreground that I already had tropical ambitions!):



Having a garden for the first time after 10 years of apartment and condo living, I went a little bit nuts.  I cut down two plum trees, a japanese maple (for which Dan has never forgiven me), and removed most of the uninspiring perennials, replacing them with bananas, palms, and elephant ears.  I've had a lot of fun with this view over the years, although it definitely took a few years to really hit my stride!  This area is now mostly planted with annuals and tender tropicals and thus changes from year to year.  Here's how it has looked in previous years.

September 2004:



September 2009, when I went a little crazy with color (but keep an eye on that palm just barely peeking out from behind the elephant ears on the left):



August 2011--yes, the palm grew that much in 2 years!  You'll also notice that my color palette has gotten a bit more subdued in recent years as I'm devoting more and more space to testing my seemannia and begonia hybrids, and let's face it, these just aren't as flashy as coleus and sweet potatoes:



And finally October 2013, looking a little tired as the days shorten and the temperatures cool down (but note that the seemannias are still going strong); as the palm and remaining japanese maple have grown and filled in, I've been experimenting with shade-loving plants like begonias and gesneriads:
