SPECIES: Philadelphus hirsutus | Hairy Mockorange
ABBREVIATION : PHIHIR SYNONYMS : NO-ENTRY SCS PLANT CODE : PHHI2 PHHIH PHHII PHHIN COMMON NAMES : hairy mockorange streambank mockorange Cumberland mockorange TAXONOMY : The currently accepted scientific name for hairy mockorange is Philadelphus hirsutus Nutt. (Hydrangeaceae) [4]. The genus Philadelphus is a polymorphic complex in need of critical study [14,19]. Hu [7] recognized the following three hairy mockorange varieties: Philadelphus. h. var. hirsutus Philadelphus. h. var. intermedius Hu Philadelphus. h. var. nanus Hu Other authors do not recognize varieties of hairy mockorage [4,8,12,19]. LIFE FORM : Shrub FEDERAL LEGAL STATUS : No special status OTHER STATUS : NO-ENTRY COMPILED BY AND DATE : Jennifer H. Carey, November 1994 LAST REVISED BY AND DATE : NO-ENTRY AUTHORSHIP AND CITATION : Carey, Jennifer H. 1994. Philadelphus hirsutus. In: Remainder of Citation

DISTRIBUTION AND OCCURRENCE

SPECIES: Philadelphus hirsutus | Hairy Mockorange
GENERAL DISTRIBUTION : Hairy mockorange occurs in the southern Appalachian Mountains from Virginia south to Georgia and Alabama. A disjunct population occurs on the Ozark Plateau in Arkansas [4,6,8,19]. ECOSYSTEMS : FRES14 Oak - pine FRES15 Oak - hickory STATES : AL AR GA KY NC SC TN VA ADMINISTRATIVE UNITS : GRSM BLM PHYSIOGRAPHIC REGIONS : NO-ENTRY KUCHLER PLANT ASSOCIATIONS : K100 Oak - hickory forest K103 Mixed mesophytic forest K104 Appalachian oak forest K111 Oak - hickory - pine forest SAF COVER TYPES : NO-ENTRY SRM (RANGELAND) COVER TYPES : NO-ENTRY HABITAT TYPES AND PLANT COMMUNITIES : Hairy mockorange occurs in deciduous forests [5,7]. Information concerning vegetation associated with hairy mockorange is lacking in the literature.

VALUE AND USE

WOOD PRODUCTS VALUE : NO-ENTRY IMPORTANCE TO LIVESTOCK AND WILDLIFE : NO-ENTRY PALATABILITY : NO-ENTRY NUTRITIONAL VALUE : NO-ENTRY COVER VALUE : NO-ENTRY VALUE FOR REHABILITATION OF DISTURBED SITES : NO-ENTRY OTHER USES AND VALUES : Mockoranges (Philadelphus spp.) are cultivated as ornamentals for their showy white flowers and general form [4,14,20]. Hairy mockorange is not one of the more commonly cultivated mockoranges [20]. MANAGEMENT CONSIDERATIONS : NO-ENTRY

BOTANICAL AND ECOLOGICAL CHARACTERISTICS

SPECIES: Philadelphus hirsutus | Hairy Mockorange
GENERAL BOTANICAL CHARACTERISTICS : Hairy mockorange is a native, deciduous shrub that grows 3 to 6 feet (1-2 m) tall. The spreading branches twist around each other and arch to the ground. Branches more than 2 years old have exfoliating and shredding bark. The fruit is a four-valved dehiscent capsule. The seeds are 0.04 inch (1 mm) long [7,16]. RAUNKIAER LIFE FORM : Phanerophyte REGENERATION PROCESSES : Hairy mockorange regenerates by both vegetative reproduction and seed. Arching branches that touch the ground root readily [7]. SITE CHARACTERISTICS : Hairy mockorange occurs along streams and on bluffs, cliffs, and rocky banks. It grows along limestone ledges and in piles of sandstone or quartzite rocks [4,7,8,12,14,19]. SUCCESSIONAL STATUS : Facultative Seral Species Hairy mockorange grows on open sites and also in forests and along streams [7], so it is probably tolerant of shade. SEASONAL DEVELOPMENT : Hairy mockorange flowers from mid-April to late May [7].

FIRE ECOLOGY

SPECIES: Philadelphus hirsutus | Hairy Mockorange
FIRE ECOLOGY OR ADAPTATIONS : Information the fire ecology of hairy mockorange is lacking in the literature. Hairy mockorange grows on sites such as streambanks and rocky ledges that may not experience fire frequently. POSTFIRE REGENERATION STRATEGY : Tall shrub, adventitious-bud root crown

FIRE EFFECTS

SPECIES: Philadelphus hirsutus | Hairy Mockorange
IMMEDIATE FIRE EFFECT ON PLANT : Fire probably top-kills hairy mockorange. DISCUSSION AND QUALIFICATION OF FIRE EFFECT : NO-ENTRY PLANT RESPONSE TO FIRE : Hairy mockorange probably sprouts from the root crown when top-killed by fire. Mockorange (Philadelphus lewisii), a species native to the western United States, sprouts readily after fire [11]. DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : NO-ENTRY FIRE MANAGEMENT CONSIDERATIONS : NO-ENTRY
