I've been stalking a neighbor's saguaro this week because it is flowering.

For those of you who don't see these giant cacti every day, saguaros usually flower in June, not September.

The flowers usually open at night, but these are staying open well into the morning, which makes them accessible to day-active pollinators like these honey bees and the carpenter bee on the right.

With all the buds, looks like they'll be enjoying flowers for a few more days at least.

Have you seen any flowers or bees this week?

It's May and the saguaro cacti are in full bloom.

Have you ever seen a saguaro cactus in bloom?


Okay, so maybe the mystery seed of the week was a bit tricky because not many people have the opportunity to see saguaro cactus seeds.



The flowers and the fruit are on top of the arms, high in the air.


The plants are only found in the Sonoran desert.


Isn't it amazing that tiny black seeds the size of pinheads can grow into a giant like this.
