There is a reason this plant is called "ordoratissima." It has a strong wonderful fragrance. Sometimes it seems to be a very clean mint smell, much like pennyroyal, other times it seems lemony. It is in the mint family, so having a strong smell is expected, but this one is especially nice. Grows in full sun to part shade. Easy to grow evergreen perennial sprawls on the ground in a picturesque manner. In bloom and for sale now at the UC Botanical Garden.

At first glance, one might think it is a cactus, but it is a Euphorbia. It is one of those adaptation things. Plants that are exposed to the same dry conditions sometimes develop the same adaptations: the accordion fold that can expand and contract easily as the moisture is taken up and used up, the succulent habit, the spines. Aren't those "cow horn" spines cute? They are different from cactus spines, and the flowers are different from cactus flowers. This specimen is in bloom now in the Arid House at the UC Botanical Garden.

Finally, a butterfly in the butterfly blog! It is dead and in a spider web, but hey, at least it is something. And it didn't move, so it was easy to get a picture of it. This is the underside of the wing, but those orange blotches look just like the orange quote marks on the Common Buckeye, so it must be a buckeye. I have see quite a few flying lately, they seem to be a late season butterfly. I should go out and look for eggs and caterpillars. I have found that the caterpillars tend to hide in the dirt during the day, and walk up the seedheads at dusk. Maybe tonight, after I get done with work, I can go hunting.

So many flowers on the island mallow now! I have seen flowers on it almost all year, but I usually see just a few at a time. I guess this is the time of heavy bloom. And I am guessing that this is the subspecies assurgentiflora because that is the one on which the petals fold back as they age. I love that deep magenta flower with the darker stripes. Cute little sigmas curling at the top. Very pretty!

Flowers are blooming in my garden, too: Crinum, passion flower, nasturtium, butterfly bush, and a rose. I gotta start looking for eggs because we are doing a show at the SF Botanical Garden August 7. I haven't seen many Gulf Fritillaries in my yard, even though I have a passion vine, so I think I am going to be scouting the neighborhood.

The damselflies are courting and mating in wet places at the UC Botanical Garden. They have a strange and wonderful copulation method. The male transfers sperm from the tip of his abdomen to a spot closer to the thorax. Then, he uses the claspers at the tip of his abdomen to grab onto a female. She bend her abdomen underneath herself and to the pocket of sperm the male hid away, thus forming a "wheel." Then, after the sperm is transferred to the female, he continues to hold onto her as she lays her eggs, so that other males don't have a chance. Talk about possessive!

The flowers on this Echinopsis at the UC Botanical Garden are big and beautiful. Looks like the ones on the bottom are blooming now, and the ones at the top, sticking out like spokes on a wheel, will bloom later. I didn't measure, but those flowers must be at least 4" across. It seems to do fine with our wet winters, although, as a cactus, this plant doesn't need too much water. Some species are small and good for growing inside, but this one is tall and impressive.

This one is easy to grow. Apparently it is widely available and has become naturalized in parts of the South. Large, pretty flowers are pink in this specimen, but can be white. It needs lots of sun and water. In Africa, where it is native, it is used medicinally for colds, rheumatism, varicose veins, and septic sores. It is also used to protect homes from evil. How could anything evil exist around this angelically beautiful flower?

This strong climber does wonders for some of the bare tree trunks at the UC Botanical Garden. It has shiny evergreen leaves and lovely white lacecap blooms. It has a long bloom season and the vine holds on to the flowers as they age, making a nice fall display. I will have to go back and get another picture.

This plant is in the kiwi family, so it is not surprising that the fruits are supposed to be edible and very sweet. However, they are also small and seedy, so maybe they are not worth the trouble of picking them. I guess I don't have to worry about how much work it is to pick the fruit because, although they grow well in this climate, apparently they do not fruit. Very pretty plant with clusters of white flowers and big leaves with prominate veins. In bloom now at the UC Botanical Garden.

I wouldn't put this in the carrot family at first glance, it doesn't have those flat-topped umbels like poison hemlock or sweet fennel. It also doesn't have those highly divided leaves like parsley or carrots. But it does have a parsely or celery sort of smell to it, so I guess it isn't too surprising. The leaves look more like those of an agave, spiky and sword-like. Rather striking structural form with low growing leaves and balls of flowers. And it makes a good dried flower. It is in several beds at the UC Botanical Garden, so maybe it is easy to grow in this climate. I couldn't find this one for sale online, but I did find Erngium yuccifolium, which is very similar. The common name of that one is "Rattlesnake Master." It is native to eastern North America and Indians used the root to combat rattlesnake venom.

This magnolia is not like the ones I am used to: the deciduous ones with furry leaves and evergreen ones with leathery leaves. This one is briefly deciduous and has large thin leaves. In traditional Mexican folk medicine, this tree was used as a tranquilizer and anticonvulsant. Studies on mice in 2006 confirm that an extract of the plant has exactly those actions. Very pretty. I wonder why I don't see it in gardens around here.
