Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: How to distinguish white-flowered Baptisias?
Answered by: Joe Marcus


How can I tell the difference between Baptisia alba and Baptisia alba var. macrophylla


Since you're located in Texas, if you have a white-flowered Baptisia blooming now, it's almost certainly Baptisia alba var. macrophylla.  In general, B. a. var. macrophylla grows larger than the type.  Also, the ranges of B. a. var. alba and the similar species, B. albescens, are limited to the Deep South and do not extend west of Mississippi.  Another, creamy-white to yellow flowered species, Baptisia bracteata var. leucophaea does occur in Texas, but it flowers in early spring.
