Layia platyglossa, or Tidytipses, is a mid spring to early summer flowering annual native to California. They are a very conspicuous flower in the landscape. Plants have a rapid growth to 16 inches tall. Leaves are linear to narrowly oblong, with the lower leaves toothed or pinnitifid. This is one of the flowers we introduced into the greenhouse this year. They are fun to grow and we will be growing them again in the future. The plant has few requirements and is hardy outside in California, but can be grown elsewhere if started early, before the last frost.
Blooming Time: Plants bloom in late spring to early summer. The 2-inch (5 cm) wide heads are very showy. Ray flowers are yellow with neatly marked white tips.
Culture: Layia platyglossa or Tidytips need full sun to light shade, with a well-drained soil mix. In the greenhouse, we used a soil mix consisting of 1 part peat moss to 1 part loam to 2 parts sand or perlite. The soil needs to be very well drained, as plants do not like to remain wet. Plants were watered and allowed to dry thoroughly before watering again. Since they are native to poor soils, we did not use any fertilizer on them. Any problems we had with this plant were very minor, and I suggest if you want a little extra color in your landscape or in containers, give this plant a try. I think you will be amazed when they bloom.
Propagation: Layia platyglossa or Tidytips is propagated from seed. Seed germinate in as little as 6 days from sowing.
Layia platyglossa was featured as Plant of the Week May 28-June 3, 2010.
