Flower color of ipomopsis tenuituba
varies greatly, often for plants in close proximity; it can be white, pale orange, pink or pale purple, but always the flowers are very pretty; a long (up to 2 inches), very slender tube ending in 5 lobes that either project out at right angles or curve backwards. At the base of the tube, which is slightly distended, are several small green bracts, while in the open end are five yellow-topped stamens; these do not project beyond the corolla as is the case for the similar and more common ipomopsis aggregata
. Stems become woody with age and bear thin leaves at quite widely spaced intervals; they usually produce between 3 and 7 flowers.
