Narrow strips like this can be a tough place for grass to grow because of the heat from the surrounding concrete and the difficulty of watering a narrow area. That's why these plants are a great choice for an area like this. Not only do they like the extra heat from the wall and sidewalk, but they enjoy being kept on the dry side. The yellow-blooming chocolate flower will thank you for not over-watering by blooming all season long! Many of the plants found in this garden are native to Colorado.
