Plants in Bloom

The outdoor gardens at Olbrich change contstantly throughout the year, but spring is one time when the weekly changes can be drastic and exciting! Make sure to plant some early visits to the Gardens to enjoy the first beautiful blooms of spring.

This is a brief outline of some of the plants in bloom at Olbrich in the spring, with an emphasis on bulbs, flowering trees, and shrubs. It's by no means totally inclusive, but will give you some idea of what you might see early in the season. By late May and early June the whole garden comes alive!
