The age of exploration isn’t over. The hunt continues for new and better plants continues.

Ever wonder where the plants at garden centers come from? Even the typical nursery features a depth of products resembling a virtual League of Nations. In addition to the plants native to North America, many originated in Asia, Europe and even Africa. How they got here is a very long story that dates back to the days of pharaohs, kings and queens who directed explorers to bring plants back from distant continents. They sought new varieties that ranged from purely ornamental to edible to medicinal.

You may have been told that bees are beneficial and that they pollinate a lot of agricultural crops. Most of the time when people talk about bees, they are talking about foreign honeybees, which were brought to North America by Europeans in the 17th century.

Honeybees are fine, but many bees that we see and call honeybees are actually native bees or flies that look like bees.

There are many other bee species native to Illinois, the Midwest and North America. While they aren’t often discussed, they do a lot of pollinating.

questions

I have a large variegated sedum with pink flowers that I have had for years. I noticed that it has started to send up some all-green shoots. Why is it doing this and how can I keep my plant variegated?

When is the best time to cut back hydrangeas? How far do I cut them back?

What does it take to make a climbing hydrangea flower? Ours was planted 3 years ago and is growing energetically. It’s in a protected nook near the patio and gets very little direct sunlight, but doesn’t act sun starved. We gave it a shot of slow release fertilizer on planting, and once since. Somewhat inadvertently it gets plenty of water, since the hose spigot is nearby and leaks, but drainage does not seem to be the problem. It now fully occupies an 8-foot trellis but shows no interest in flowering. Is it youth, lack of sun, too much or too little fertilizer, bugs, lack of pruning or what? When do these plants bloom and what conditions do they like?
