The forecast for today is 91 F (32.8 C), and if we reach that temperature it will be the first time we have broken 90 F this year. May 15 is the average date of the first 90 degree day, so we are right on schedule.
1. Herbertia lahue subsp. lahue
Herbertia lahue has three subspecies–H. lahue lahue, H. lahue amoena, and H. lahue caerulea–and a really odd distribution pattern. The first two subspecies are native to Argentina and Chile, while H. lahue caerulea (prairie nymph) grows along the gulf coast of the United States. This odd disjunct range is shared by several other bulbs and may indicate very early introduction of South American plants to Spanish colonies in North America.
The flowers of H. lahue, like those of many irids, are very short lived, and the small stature of the plant makes them easy to overlook. Last year, I found a few seed capsules but didn’t see any flowers. This year, I missed the first flush of flowers, as indicated by the green capsule in the foreground, but I happened to walk past the plant just in time for the second flush.
Similar to its larger relatives Cypella herbertii and Cypella coelestis, H. lahue is remarkably cold hardy for a South American plant. It produces its tiny iris-like leaves in winter and goes dormant in early summer.
2. Penstemon murrayanus (scarlet beardtongue)
This fantastic Penstemon grows naturally in scattered localities in east Texas, Arkansas, and Louisiana. I like the bizarre perfoliate leaves almost as much as the bright orange-red flowers. It’s not difficult to guess the pollinator–hummingbirds, of course.
I planted a seedling last May, so this is the first time it has flowered in my garden. Hopefully it will produce seed after self-pollination. Penstemon digitalis (photo 5 of SoS #29) is blooming on the other side to the house, so I suppose hybridization is possible. It’s probably unlikely, though. The white flowers of P. digitalis are pollinated by bees, not hummingbirds.
3. Borago officinalis (borage)
I don’t usually grow annuals, but I’ll make an exception for borage with its fuzzy buds and beautiful blue flowers. It’s one of the traditional garnishes for a Pimm’s No. 1 Cup…and now I’m getting thirsty.
4. Ocimum kilimandscharicum x O. basilicum (African blue basil)
I picked this up at the Durham farmer’s market simply because we like to try different types of basil in the kitchen. I had no idea that it was such an interesting plant. African blue basil is a sterile hybrid of culinary basil (O. basilicum) and camphor basil (O. kilimandscharicum), If the second species epithet reminds you of “Kilimanjaro,” you’re not wrong. O. kilimandscharicum is native to east Africa. Unlike the the usual culinary basil varieties, which is easy to grow from seed, African blue basil must be propagated from cuttings. Apparently, it roots easily, flowers almost constantly, and is reliably perennial, though not frost hardy.
My wife thinks the African blue basil smells like regular sweet (Genovese) basil, but I detect a definite camphor fragrance that is presumably inherited from O. kilimandscharicum.
5. Lonicera sempervirens forma sulphurea ‘John Clayton’
‘John Clayton’ is, as you can see, a yellow clone of our usually red-flowered native coral honeysuckle (see photo 2 of SoS #26). It was originally planted on this pergola together with red L. sempervirens ‘Major Wheeler’, but the voles ate ‘Major Wheeler.’ Hummingbirds and this gardener agree that red clones of L. sempervirens are better, but ‘John Clayton’ is growing and blooming so vigorously that I haven’t the heart to remove it and start over..
6. Teucrium marum (cat thyme) and Felis catus (moggie)
Bly the cat and his sister Neem both really enjoy visiting the Teucrium marum that is growing in dry sandy soil beside the gravel path leading to my greenhouse. These pictures also illustrate how we let Bly go out in the garden without endangering the local lizards and birds (and without Bly becoming a snack for the coyotes). He tolerates the harness well, as long as the human trails along behind him rather than trying to lead him.
