Notable plants I will rely on more in the next few years. These have been doing good in hot hot hot, and dry dry dry conditions. That makes them perfect Texas garden companions.
Sweet Potato Vine, however, spreads like wildfire in the ground, definitely a container only plant. Blackie is better behaved, and not as vigorous as Limelight, and Tricolor. and they are soooooo easy to propagate. just stick 'em in water and roots form. I have also stuck them straight into moist potting soil, making sure the soil stays wet/moist for about a week, and then you have a new plant. Does really well in drought conditions, especially in the I forgot to water my containers for a few days, kinda drought. I see them around town planted in the ground, and they always look lush. When I pick garden bouquet, I like to add some sweet potato leafs, gives some great foliage.
Oh and as a nice bonus, blackie produce pink petunia like flowers, if you're lucky.
