Poet Dorothy Parker once scorned her lover's gift of "one perfect rose." Perhaps her boyfriend's mistake was not going to Buchanan's to buy his present. The beautiful Heights plant-and-flower shop offers so many different types of roses it would have been hard for him to stop at just one. The shop, staffed with knowledgeable flower lovers, offers everything from hearty, disease-resistant antique roses to the more finicky but beautiful hybrid teas, known for their large flowers and strong scent. Reasonably priced (some roses sell for just $10.99 a gallon), the offerings include every color you can think of, from red to white to purple. Buchanan's is also in regular communication with the Houston Rose Society, a group of locals in love with the popular plant, so you know it's got its fingers on the pulse of the rose world.
