Annuals can provide inexpensive color to any garden. Or, you can spend a bunch on annuals that will take your breath away. When planting Begonias, I buy cheap ones for the garden, but spend more for fancy ones on my porch.
Begonias are my second favorite annual. I purchase planting packs of Waxed Begonias that go in the ground. Costing as little as $1.09 for four at a spring sale, Waxed Begonias provide a summer of color, and can take both sun and shade without excessive watering. If we have a mild winter, they will come back for a second or third summer.
On the flip side, I spend up to $4.50 each for smaller traditional or Hiemalis Begonias. I buy three every year for my north-facing porch. These Begonias provide stunning color for six months, and receive praise from most visitors. If you want to buy bigger traditional Begonias, you can spend a whole lot more.
A funny note about annuals: When I first started gardening, I would be bummed when I saw the huge annuals on commercial properties. I wondered what I was doing wrong. It took me a couple of years to realize the commercial annuals were being raised in green houses. I could buy the same thing, but I’d have to pay a lot more for the plants. I’d rather raise them myself.
