Plant in full sun to light shade in a well-drained soil. After plants are established, fertilize and water sparingly. It is hardy to about 20 degrees F. The flowering plants with their wonderful face like flowers are quite beautiful when in full bloom and are also attractive to hummingbirds. Often the plants can look a bit haggard later when not in bloom, so are best in areas where they can be enjoyed from a distance and left to dry out mid-summer until rejuvenated by fall and winter rains. Some summer shade helps prolong flowering and foliage as does a spritz of water, but regular irrigation through summer usually shortens the plants life.

Mimulus 'Jelly Bean Yellow' is a selection made in 1998 by Richard Persoff from breeding of two Mimulus aurantiacus parents. It was selected on the basis of its compact and freely flowering habit. It was issued Us Plant Patent PP11,973 and this patent has since expired. It is also known as 'Princess Jessica'. Other plants in this Jelly Bean Series include Mimulus 'Jelly Bean Apricot', Mimulus 'Jelly Bean Dark Pink', Mimulus 'Jelly Bean Fiesta Marigold', Mimulus 'Jelly Bean Gold', Mimulus 'Jelly Bean Lemon', Mimulus 'Jelly Bean Orange', Mimulus 'Jelly Bean Purple Pink', Mimulus 'Jelly Bean Red', Mimulus 'Jelly Bean Terracotta', Mimulus 'Jelly Bean Yellow' and Mimulus 'Jelly Bean White'. We grew and sold this plant from 2002 until 2006.

In the newest treatment of the tribe Mimuleae, which includes Diplacus, Mimulus, and Mimetanthe, these plants have been removed from the Figwort family, Scrophulariaceae, and placed with the genus Phryma (previously included in Verbenaceae) into the new family Phrymaceae. The woody species of Mimulus that are the parents of most of the hybrids have been separated into the genus Diplacus in the past, then gone back to Mimulus, but in the current treatment in the UC Berkeley Jepson eFlora all of the woody Mimulus are back in the genus Diplacus. This change has not been accepted by all and not to cause undo confusion for our customers and staff, we continue to use the name Mimulus until such time as this name change is more widely known. The original generic name is from the Latin word 'mimus' meaning "mimic actor" that is derived from the Greek word 'mimos' that means means "imitator" and references the flowers that look like painted faces. The name Diplacus comes from the Greek words 'di' meaning "two" or "double" and 'plax' or 'plakos' meaning "a flat round plate", "tablet" or "broad surface" in reference to the manner in with the fruit capsule splits. 

The information about Mimulus 'Jelly Bean Yellow' displayed on this web page is based on our research conducted in the nursery's horticultural library and from reliable online resources. We also include observations made about it as it grows in our nursery gardens and other gardens we have visited, as well how the crops have performed in containers in our nursery field. We will also incorporate comments we receive from others and welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant.
