This genus of plants is so well known that any remarks would be useless; there are, however some of the handsomest members that have been but very sparingly, if at all, introduced to cultivators. These are natives of California, where, in their wild state, they fill the valleys and cover the hill-sides with the gayest of blooms from May to October.
Within California and vicinity there are found some twenty odd varieties, all of which are fine blooming plants, but to describe which would take up a whole number of the Monthly, therefore I shall only speak of a few of the finest, and which I deem most worthy of cultivation.
