Tobacco plants change pollinators to ditch worms
Sure, the hawkmoth does a good job of pollinating the plant, Nicotiana attenuata, which grows in the Western United States and flowers at night. But the hawkmoth has this annoying habit of leaving behind its eggs, which develop into caterpillars that like nothing better than to eat the plant.
So N. attenuata strikes back in a novel way, according to scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany. As they describe in Current Biology, it shifts the time of its flowering to mornings and attracts a different pollinator, a hummingbird.

Thryalis Galphimia gracilis

This shrub will easily reach 6′ tall in Houston and 4′ across. It is a very dense shrub right down to the ground. There’ll be no bare legs hanging out underneath.
Thryalis prefers full sun, it will grow in part shade but it’ll get leggy on you.
Blooms prolifically mid spring to early winter.
Drought tolerant once established. Excellent for barriers and low maintenance areas.
Birds, bees and butterflies are attracted to this plant.
Hardy to zone 8 but will die back in the winter in zone 8.
This did not survive not sure if last summer’s drought, this winter’s freezes or a combination of the two is responsible.
Propagate by cuttings.
Sometimes referenced as thryallis
Nothing interesting to report yet, this plant is only glancingly referenced in my books and I just picked it up this week.

It was love at first sight when I first saw this plant at a botanical garden in San Antonio. I was able to acquire one at the Extension Office plant sale this spring. Hummingbirds also love this plant.
Flowers may be purple or white, grow on 6″ stems, and have very long stamens resembling cat’s whiskers. It is a flowering shrub that can reach 4′ in height with a 3′ spread. Flowering occurs late summer through early fall in most places, can bloom year round here in Houston.
Cat’s whiskers prefers full sun, but will tolerate partial shade. Keep the soil moist and do not let this plant dry out. It wilts stops growing and flowering when the soil is too dry.
It is a fast grower and blooms easily.
Cat’s whiskers can be easily propagated from cuttings.
If you are looking for an unusual plant that is easy to grow consider this one. The picture really doesn’t show just how wonderful the blooms are.
This plant loves the summer heat, but died after a winter freeze.
Java Tea is made from this plant and said to help pass kidney stones.
Keep an eye out for scale on this plant.
Be free with the pruning shears it will thicken up after heavy prunings.
