Here's is a nice bright yellow bloom, on a Tiger Jaws (Faucaria tigrina).

Sundews and the Pollinator-Prey Conflict!

     A "pollinator-prey conflict" arises in sundews, because they need insects both as pollinators for reproduction and as prey to acquire nutrients from nutrient-poor soil, creating a potential dilemma where they might trap and consume the very insects that help them pollinate their flowers.  To mitigate this, many sundew species have evolved adaptations like spatially separating their flowers from their sticky traps, allowing them to attract pollinators without significantly risking their capture.

     This sundew is growing a flower stalk that will be much taller than it's sticky leaves.  The bloom stalk has a row of buds.

      The stalk can hold a dozen or more flowers, one bloom opening every day or so. The white flowers are up to 3/4 inch in diameter.

     This plant is self-pollinating, so there are plenty of these plants growing in my collection.  I remove almost all of the bloom stalks so  more energy can go into growing the plant.

How A Sundew Eats!

Drosera capensis ‘Cape sundew'

     This Drosera capensis aka Cape Sundew, is a carnivorous plant that has a fascinating process of capturing and digesting insects.  The flat leaves on this sundew are covered in small stalked glands or tentacles.  The tentacles are hair-like filaments, and at the end of is a small gland that produces a tiny drop of dew: a clear, gluey mucilage that is extremely sticky.

A small flying insect may catch sight of the glistening droplets and mistake them for a flower's sweet nectar. It alights on the leaf and is immediately caught in the glue, and struggles to free itself.  The more it thrashes, the more mired it becomes in the tentacles.  The tentacles quickly begin to move, carrying the victim toward the center of the leaf, where more glands await.

     Usually the prey of sundews suffocate when the breathing holes (spiracle) along their abdomens are covered in glue.  Once an insect is caught, the highly developed glands begin to secrete a complex juice of enzymes and acids that rapidly covers the insect's body.  In a matter of hours or days, the digestive juices liquefy the softer parts of the insect. The glands then begin to reabsorb this nutritious soup.  On larger insects the leaf will curl around its prey.

The leaf is bending around a spider. Notice how the end of the tentacles have moved to trap and digest the spider.

A leaf has folded to trap and digest a large insect.  Notice the leaf on the left with many small bugs that have been trapped.  The leaf doesn't fold on small insects.

     

After digestion, the tentacles usually dry up and return to their normal upright position. The shriveled carcass falls from the leaf, is washed off by rain, or simply remains as a dire warning to future prey. Dew drops reappear, and the leaf is ready for another meal. Sometimes older leaves remain curled up even as the leaf turns brown and dies. During their active growth cycle, most sundews continually replace older leaves with new ones.

Blooming Surprises!

 I was walking around the garden and was surprised to see some of these blooms.  

Plumeria

This plumeria has been growing several small branches and lots of leaves since August and now all of a sudden it has some blooms in early November!  I like the pale pink color and it has a slight fragrance.

Epiphyllum

This white epiphyllum is growing right next to where I park my car.  I like the long thin petals on this bloom.

Feather Cactus, AKA Mammillaria plumosa

The small blooms can be easy to miss on this Feather Cactus, AKA Mammillaria Plumosa.  The spines on this look and feel like fine feathers.

Passion Flower

The Passion Vine continues to produce a bunch of blooms and as you know, it's one of my favorites.

Happy Halloween!

I hope everyone has a safe, fun and happy Halloween!

Sarracenia Hybrid Update!

    I bought this Sarracenia hybrid of (x ‘Leah Wilkerson’) x (‘Wilkerson’s Red Rocket’) three months ago and at that time it had a couple of pitchers that were about 2 inches tall.  Since then it has been growing new pitchers and they are getting wider and taller, but still under three inches.  It will be going dormant in a couple of months and then next year I expect it to get much taller.  

     The pitcher on the right has been eating well!  With the back lighting, you can see the level of dead and digested bugs in the pitcher.  These are mostly ants!  If you look at the pitcher on the left you can see a hole in the pitcher.  A bug fell into the pitcher but could not climb out, but was able to eat a hole and escape!  

     I find these plants fascinating!

Walking Stick

Walking Stick Insect

 I found this walking stick insect in my workshop this morning.  It's small, with a body that's only 3/4 of an inch long.  I think it hitched a ride on my sleeve, so I released back outside.

Bee in the Bloom!

 This trumpet vine has been growing and now blooming outside our kitchen window.  I’ve been watching bees go in and out the blooms.

September Cactus Blooms!

 This is one of my favorite cactus and I have had it for a long time, at least 15 years and possibly many more.  It bloomed again a few days ago.  I think this is the third time it has bloomed this year and it is every bit electrifying in person.

Rebutia Cactus

The Flying Saucer Cactus bloomed earlier in September, It normally blooms in May and early June.

This gives you an idea of the size of this flying cactus bloom.

The next day it was 105° and the bloom didn't like the heat!  I didn't  like the heat either!

A Tale of Two Caterpillars

 So I saw the tell tale signs of fritillary caterpillars on my passion flower vine.  There were lots of little holes in the leaves, so they were just getting started.  Once they get going, they can defoliate the plant quickly!  I began looking for the culprits.  I found a bunch of eggs that I removed, but only one small caterpillar.  I also found a white/beige caterpillar that I didn’t recognize and it was very wiggly.  Instead of the usual squish method, I thought I’d feed them to my Venus flytrap!  I dropped the Gulf Fritillary caterpillar into a trap and it closed instantly.  The fly trap did its job and started digesting the caterpillar.  A few days later, the trap opened and you can see the remains.

As I mentioned above, the unidentified white/beige caterpillar was very wiggly so I took care to drop it into the center of a trap.  It closed very quickly and I could see the silhouette of the caterpillar moving in the trap.  I came back an hour later intending to take a picture of the trap with the silhouette of the caterpillar.  But instead, I found this round hole.  The caterpillar had eaten its way out of the trap and escaped!

Tuberous Begonias - Paul Carlisle & Chapman Estate

 Our begonia branch (Rudolf Ziesenhenne, Santa Barbara, CA) recently visited Paul Carlisle's shade-house and the Chapman Estate shade-house to see tuberous begonias.  It was a tuberous double feature! 

 If your familiar with my blog, you have seen the tuberous begonias grown by Paul Carlisle.  They are incredible!  I would confidently say that Paul Carlisle is the best tuberous begonia grower in the United States!  It's always a treat to visit his shade-house when the tuberous are in full bloom!  Here are pictures taken in Paul's shade-house.
