--><p>Baileya is perhaps best known by B. multiradiata, which is the most widely distributed, most abundant, and (usually) earliest blooming of the three species in the genus. The large-headed vernal form is particularly attractive; this, together with its long flowering season and its drought tolerance, have given the plant recognition in horticultural circles.</p>
