“Hardy hibiscus”, which are horticultural hybrids of several H. species. These live in a big pot, and every year I wonder if they’re even alive because they don’t even send up stems (with maple-like leaves) until like June. I take them into the garage for the winter- “hardy” is a relative term.

Four o’clock flowers (Mirabilis jalapa), an old-fashioned flowering annual. I hadn’t realized that it forms a tuber, but this one is in its third year after being lifted in the fall and stored in a paper bag each winter. It’s bigger every year! The hummingbirds are big fans.

Truly. I only play blackjack (basic strategy with a simple card count on top of it). But there are places that only pay out a blackjack at 6:5, and I’m not touching that. Mind you, most customers play as if they’re lurching drunk even while completely sober, so these are fine distinctions. . .

I've grown that picotee type as well, but they never reseeded for me, so I didn't see this effect. But I think it's found in a lot of Ipomoea varieties - the recessive traits that give them the neat forms and coloration gradually get submerged over the generations.

TL;DR: 5 justices say Trump doesn't have to immediately restore the funding, but 5 *also* signal that the underlying directives are unlawful. That sends a fairly strong (if mixed) message that Trump will lose these cases *eventually,* but only once they're brought in the Court of Federal Claims.
