I looked at something today and decided that it was hot. Maybe it was the thermometer or the weather report or the big red handkerchief that wiped the sweat on my brow. That got me thinking about plants that like it hot, which in our case is often on the dry side, too.
It's the afternoon sun on sites facing west or the all day sun of a southern exposure that challenges some of our favorite garden plants.
My first perennial thought was the prairie natives from a bit further west. In fact, many of them were growing here before we arrived to cut down the old growth forests whose shade had eliminated many of the sun-loving plants.
If you didn't follow that, this area was grasslands first which was crowded out by the succession of trees, long before the first settlers arrived. If you did, don't read this paragraph.
I'm thinking about black-eyed-susans, coneflowers, liatrias, baptista, and bluestem grasses, to name a few. That is a quick fail-safe list from the many perennials that will take the heat.
Rudbeckia (black-eyed susans) come with several looks and sizes. 'Goldsturm' is the one you see planted everywhere, but I have a smaller one that is gaining a major foothold on a large weedy bank. I fret about the weeds there, but am impressed with who seems to be winning the battle.
Maybe lazy might be the best approach to that problem bank. I'm learning to do that better and better. Time will tell.
Recent selections and hybridization have brought us a wonderful variety of echinaceas (coneflowers) and baptistia. I believe we have written in detail about these not too long ago.
My current observation is that the new coneflowers are a bit less ambitious than the older purple ones. I would plant them away from a lot of competition. I'm also doubtful that they will come true from seed.
To date, I believe the new baptistias are similar in vigor to the original offerings. When planting them, pick a spot and leave them there. They have a tap root which makes them more difficult to transplant and will sprout from root fragments left when you dig them up.
Liatris is a tall perennial with a long blooming stem and season. Normally, they are in the purple range. They will form a nice clump over time. There are several sizes to pick from.
The bluestems are warm season grasses that also come in several sizes. They might be my favorite grass.
I asked my wife to give me three good annual options for difficult hot spots. Our conclusion is that since most annuals are really tropical perennials, there is a long list that will work.
Two that standout are flowering vinca and portulacas. Grandmother introduced me to portulacas when I was knee-high. Back then a seed packet and a bit of neglect gave you years of enjoyment. In other words, they reseeded naturally in the garden if left alone. I am not sure that today's hybrids will reseed.
Vinca is just a blooming machine for the hot, drier spots. What else can I say? Just don't plant it early as it despises cold soil.
Looking how much is written above I get nervous because I am only half done. I still need shrubs and potential problems with hot sites. We'll go there next week.
