Flower visitors

I enjoy watching flower visitors. Are they collecting nectar or pollen (or both)? How are they visiting the flowers? Many are effective pollinators, transferring pollen between flowers, but not all are.

This bumblebee was sonicating ('buzzing') horsenettle flowers (Solanum carolinensis) to discharge pollen. Then, they take the pollen back to provision underground brood cells. About 8% of the world's plant species require 'buzz pollination' to effectively transfer pollen to stigmas.

Some large bees (such as this carpenter bee) 'rob' the nectar of available flowers, such as this Salvia, poking a hole in the base of the flower (corolla) tube.

Butterflies rely on nectar for a source of energy as adults, some getting energy from rotting fruits. Some will collect salts and minerals from shallow puddles, dung, or salty spots. Here's a silver-spotted skipper visiting a bee balm flower for nectar, getting an energy-rich boost.








Photo note:
My gardening companion took the horsenettle and bee photo, and a fellow educator just sent me the photo of the skipper visiting bee balm.

Garden sage

Common garden sage can be pretty tough, unlike the more wimpy versions that are variegated or purple and white. I stuck a sad-looking plant that had been in a pot for awhile between the fence and an Illicium -- and it's been flowering away, in spite of relatively little sun and no care.

In contrast, a plant in full sun in the satellite garden, also a bit of an afterthought, is flourishing in a nicer spot, surrounded by garlic.

I like Salvia species of all sorts because their flowers are favored by bees, butterflies, and hummingbirds. This culinary sage is even handy when a few leaves are required.

Hummingbirds are everywhere

We've had fun watching the hummingbirds whizzing around the garden lately. Right now, it seems that we have five. An adult male, 3 females, and a juvenile male. The adult male has just arrived, probably passing through on his way south, but the others have been here for a while. The females chase each other around, but fairly companionably, and they seem to be friendly with the juvenile male. Yesterday, it almost looked like one of the females was the 'mom' and the juvenile male (he only has a few red feathers on his throat) was wanting her to feed him. We have two feeders near the porch, where we eat during nice weather (basically April to October), with an additional feeder on the other side of the house. But there are also the nectar-rich flowers of the Salvias (S. guaranitica and S. coccinea) and the coral honeysuckle (Lonicera sempervirens) and the Buddleja flowers for nectar. There are lots of insects, too, in our garden.

My gardening partner has been busy this weekend moving mulch --lots of freshly chipped trees from our campus that the tree service fellows were happy to give us (we gave them a nice 'tip'). He's moved one truckload already, to nourish the front woodland garden. The second two loads will add mulch to the back garden, and other areas. Organic matter is solid gold to add to your garden.
