Azalea
You’ll recognize this one straight away from its soft red petals contrasting with dark little green leaves. The flowers can be so abundant it’s a wonder the rest of the plant can hold them up! These bloom in the spring but will last weeks once they bloom, unfolding slowly at first. Give them acidic soil (a mix of soil and bark works best) and ensure that there’s a viable drainage hole at the bottom of the container, which should also provide your azalea with lots of space. Expose your plant to lots of sunlight during the day, and if you can swing it, offer it some shade in the afternoon.
Bougainvillea
Who doesn’t love bougainvillea, with its streams of vivid pink flowers climbing up walls and fences, signaling the arrival of spring? This tropical vine flowers beautifully, and three times at that–once in spring, summer, and fall. You can start it in a small container, keeping the roots a bit crowded. Load it up with regular potting soil, add some drainage holes, and then let it go. Once some time has passed, keep the soil on the dry side. Offer your bougainvillea fertilizer on the regular, and prune as you see fit. This vine is a natural climber, so position your container in an area where you’d like to see a vibrant wash of color.
