Outdoor wild Hybiscus. I have one planted at the bottom of my yard. They grow very tall and get huge flowers. They need trimming back in the fall. I have never seen the wild variety in yellow. I have only see pink, white, and red.
As you can probably tell, yellow is my favorite flower color! One flower I cannot do without each year is the tropical yellow hybiscus. It can grow outdoors in pots and needs partial sun from spring-summer but must come inside when fall approaches. It looks great on a patio or front porch. It does not like drafts. You shouldnt plant it in the ground either as it will grow too large to bring inside in the fall. This color of hybiscus is extremely hard to find and the plant itself is not very hardly but I love it.
Good: needs to remain inside until weather consistantly stays warm, blooms continuously throughout the entire summer
Bad: does not do well in drafts, needs constant watering but not too much watering, is prone to getting aphids , flowers have no fragrance, flowers only last 2 days
Season: flowers from mid May - end of Sept (if weather says warm)
