Portulaca grandiflora (Moss Rose / 9-O'Clock Flower) is the ultimate summer flowering plant for Indore's extreme heat. Blooms open beautifully in bright sunlight and close at night. Semi-succulent leaves store water, making it remarkably drought-tolerant. Ideal for rocky gardens, terrace edges, and sunny window boxes. Very inexpensive and easy to grow. Spreads naturally to form a colorful carpet of blooms in red, pink, orange, yellow, and white.
