Lemon LightsOne of the Northern Lights series of deciduous azaleas developed by the University of Minnesota, 'Lemon Lights' is a lovely deciduous azalea with nice lemon yellow flowers on a large growing plant. Give 'Lemon Lights' plenty of room to grow, as it will be 6 ft. tall and 8 ft. wide in 10 years. This plant is extremely hardyto 30 F! So if you live in a cold part of the country, this azalea will perform just fine.
