My 2-packs consist of one tree about 4" in height, and the smaller tree about 3" in height (Three photos on left are HO size). For shorter version, order my N scale 2-pack (Cactus section) which are two trees about 2 1/2" in height (pictured with pliers above). Trunks & limbs are Kakhi in color. If desired, these can be customized by the customer by drybrushing. To be more realistic, you'll want to either gently clip off roots & plant in pre-drilled hole, or bury roots in Sculptamold, caulk or plaster and paint surface.
Joshua Trees are found in harsh desert environments. (Also consider my Palo Verde trees & cacti.)
