a new rule, and a milkweed

I have this new rule. No gardening if the humidity goes over 15 percent. Steam baths are not for me. With all the rain, the humidity is an almost unbearable 20 percent, and so I’m staying inside.

I am a humidity wimp. Fortunately for me, as the temperature rises here, the humidity goes down. Give me a hundred degrees and five percent humidity any day of the week. I’ll be outside working.

Anyway, it gave me an excuse to race outside, cut this flower and bring it inside to photograph it. I know, it looks like something waiting for you at the bottom of a pit in a science fiction movie. It’s the flower of the showy milkweed, Asclepias speciosa.

There’s some interesting information on the relationship of milkweeds to the monarch butterfly on the Monarch Watch website and photos of many (not all) of the native species. Some, like the showy milkweed, will survive on our natural precipitation, since it grows right around here. The Antelope Horn, Asclepias asperula, is one of the coolest-looking, and will accept very dry conditions (I think mine isn’t going to bloom this year; it must have its reasons), and I’m still waiting for someone to give me seed of A. pumila; I’m to lazy to drive anywhere to collect it. There are spine-tinglingly desirable dryland species for the rock garden like A. cryptoceras and A. ruthiae, but they’re as difficult to keep in the garden for any length of time as they are desirable. (I don’t want to hear from anyone who has drifts of them in their garden.)

a clod of soil

The Madonna Lily, Lilium candidum, the only lily I can really grow. And no wonder. In The Larger Bulbs, Brian Mathew says “I have seen it in Greece growing in clumps on the flat roof of a house in the Peloponnese, flowering magnificently in a clod of soil.” And in Flowers of Greece and the Aegean, by Huxley and Taylor, the habitat is described as “dry stony slopes, thickets, in Epirus, Peloponnese, and the Eastern Aegean islands.”

These have been in the garden for a long time, growing in hard clay mixed with pea gravel kicked in from the nearby path. (Border collies running up and down.) It took the lilies a while to do anything, but now they flower pretty reliably. I would say that their water needs, in excess of natural rainfall here, are negligible.

When you can get them (I don’t know of any mail-order bulb companies offering them this year), they usually ship in August, at which time you plant them with the tops right below the surface of the soil, a half-inch or so. No deeper, because the lily sends up a rosette of green leaves that overwinter, even here.

Now what I want (see how this works? one thing makes you want another) is its hybrid with another Greek lily, Lilium chalcedonicum. This is Lilium × testaceum, flowers of isabelline, the color supposedly named because Queen Isabella of Spain refused to change her underwear until the siege of Ostend was lifted; the siege lasted three years and the queen’s underwear were said to have turned this color.

This turns out to have been a myth, but maybe this is the reason for the exceedingly high price of the bulbs. Years ago, when you could still find them, they sold for upwards of sixteen dollars each. A lot of money to pay to get flowers colored like someone’s old underwear.
