As a California native, Orange Globe Mallow does best with no summer water and well drained soil. I have it planted in the garden in such a way that the sprinklers miss it, and again in a dry bed next to the driveway. It is doing well in both locations, but best in the un-irrigated bed. I absolutely love the bright orange flower spikes and how they contrast with the grey folliage. Seems to constantly be in bloom too!
i grow this in 'desert' gardens here in the bay area. it quickly spreads to form a mat, 7 or 8 ft around. it does well in large pots as well - cascades. it's a fast grower and a prolific bloomer. i just acquired two w/ variegated leaves. don't give it too much water or it will get v. leggy and might not bloom as well. it's a great plant for early spring color.
