Michael's Opinion

An uncommon but attractive shrub to small tree with very large and long blooming flowers. It makes for a good specimen plant due to its attractive rich green foliage and bright flowers that last throughout the spring and summer. It has no major pests or diseases, and can grow in shady areas and poor soil as long as it is moist.
