Choosing the Best Flowering Plants
The question starts out something like this: “Neil, what are the best flowering annuals and perennials (or vines and shrubs) I can use in my landscape?”
That’s when my thoughts roll back over the four months I spent writing those four chapters of Neil Sperry’s Lone Star Gardening (one long month each) and the extensive charts and lists I prepared for each.
Many of these plants, especially the vines, shrubs and perennials, bloom for only a few weeks each year. That makes it all the more difficult to make my selections. I have to choose carefully.
Factors that enter the picture…
Consider each of these as you choose plants to colorize your gardens this season.
• Where do I live? More specifically, what is the USDA Plant Hardiness Zone for my part of my county? We’ve proved it several times since the new map came out in 2012 – it’s best to use the old 1990 map. The 2012 map moved Zones too far to the north. Will that plant survive in winters in my part of Texas? (Of course, this only applies to shrubs, vines, perennials and cool-season annuals.)
• What size of plant (mature size) am I looking for? I don’t want to have to prune it and shape it time after time? Plants wear out if they’re cut back repeatedly. How much room do I have for it? This is where people who repeatedly butcher their crape myrtles by topping them just to keep them in bounds would be so much better served if they’d just choose a smaller variety instead.
• Does it need full sun, full shade or something in between? Do I have that kind of setting? And be sure you’re reading information written for your part of America. Nursery tags tend to be written for the Midwest and East Coast, not for sunny old Texas.
• Will it grow in my soil? Or perhaps, might I have to do extensive bed preparation if it’s to survive? (This is why you shop at an independent retail garden center, so you can ask a veteran nursery person.) And remember that it’s almost impossible to amend the soil for a large shrub or tree to satisfy its long-term needs. It would require many dump truck loads of good soil. That’s just not practical.
• Does it have any serious insect or disease problems? Are they things that are difficult to eliminate? There’s no point in planting a tree or shrub with known issues. Go for the easy ones.
• When does it bloom, and is it compatible with other plants in our gardens? You’d think that all flowers would work in harmony with all of the rest, but that’s simply not the case. See how they look in other people’s landscapes before you commit on your own.
• What colors are its flowers? Will those work for me? Are other colors available? Do the leaves have any special colors at particular seasons?
• Do the flowers have an aroma? Is it good or bad? If the former, plant it where prevailing winds of its bloom season will blow it toward you, not off the property. If the aroma isn’t so good, use it farther out in your landscape, away from entries and patios.
• How does the plant look when it isn’t in flower? Some plants are almost unsightly when they’re not blooming, and that’s why I decided a long time ago that l will only use the best of the flowering shrubs, trees and vines. I can get annual and perennial color at the other seasons for longer bloom times and without having to put up with a woody plant that is less than handsome the 49 weeks that it isn’t in flower.
