Portulaca Extra Double Mix is an excellent mixture of many bright colours in double form. Useful for bedding, rockeries and in crazy paving where seeds can be directly sown where they are required. Portulaca, or moss rose, is a popular drought-tolerant annual. Plants are low-growing spreaders with thick succulent stems and vibrant, cup-shaped flowers. They love it hot and dry and you can even plant them in poor, sandy, soil. They also adapt to average garden conditions. Just give them full sun and any well-drained soil.
