Philadelphus mexicanus 'Double Flowering' (Evergreen Double Flowering Mock Orange) - This is a climbing evergreen shrub that can clamber to 15-20 feet. If used as a groundcover the shrub will reach 3-5 feet tall and spread 15 feet. Very fragrant (they smell like Tuberose!) creamy double white flowers bloom in the late spring to summer and sometimes again in the fall. Plant in sun or part shade with regular watering in a relatively well-drained soil. It is hardy to at least 22 F. We long grew the single white Philadelphus mexicanus but this double white flowering form came to us in 1993 from the grassman John Greenlee. It had been planted in his Pomona garden by the late Dennis Shaw, an amazing landscape designer who worked at Marshall Olbrich and Lester Hawkins' legendary Western Hills Nursery. We have retained the descriptive name 'Double Flowering' for this plant but note that it is likely the same as the plant that we have more recently seen being offered as Philadelphus mexicanus 'Flore Plena'. Philadelphus mexicanus grows in the wild in Central and Southern Mexico and Guatemala. Long placed in the family Saxifragaceae, the genus is now considered to be in the Hydrangeaceae. The name Philadelphus was given to the genus in 1735 by Linneas in honour of Ptolemy Philadelphusm King of Egypt from 283 to 247 BC who was a patron of literature, science and art. Philadelphus was long placed in the family Saxifragaceae but the current treatment is to include it with our native Bush Anemone in the Philadelpheae tribe of the Hydrangeaceae.  The information on this page is based on research conducted in our nursery library and from online sources as well as from observations made of this plant as it grows in our nursery, in the nursery's garden and in other gardens that we have visited. We have also incorporated comments received from others and always appreciate getting feedback of any kind from those who have some additional information, particularly if this information is contrary to what we have written or includes additional cultural tips that would aid others in growing  Philadelphus mexicanus 'Dbl Flowering'.
