Tech Tips: Whimsy Calocephalus is a compact plant that has low water and fertilizer requirements. Use plastic tenting or Reemay ® fabric during propagation if needed to keep high humidity, and to minimize excess water on the foliage. Provide moderate to warm temperatures early on after transplant to get the plants established. Avoid over-saturated media and overly cool temperatures. Whimsy Calocephalus may form bright yellow flowers on very mature plants, but its main value is its unique silver foliage.

Provide moderate to warm temperatures early on after transplant to get the plants established. Avoid over-saturated media and overly cool temperatures. Helichrysum italicum may form golden yellow flowers on very mature plants, but its main value is its unique silver-colored foliage. Trimming plants is the best way to control growth.

Tech Tips: Café Au Lait will start to produce semi-double and single flower forms as the day lengths get shorter and cooler into the fall season. Café Au Lait will also be more prone to produce semi-double or single flowers when under various forms of stress from heat or suboptimal irrigation and nutrition during establishment. Nutrition should be maintained through vegetative bulking and flowering in order to support production of fully double flowers longer. If plants are a light green or yellow tone they should be fertilized until tone improves to a healthy, green tone.

Tech Tips: Long-day lighting (day length extension or night interruption) is needed during propagation to avoid premature flowering and tuber formation. Ideal photoperiod during finishing to provide the correct balance between vegetative growth and flower formation is between 13–14 hours. Growing under very short natural days (< 12 hours) will result in short plants, fast flowering, and root tubers. Provide warm temperatures early on in finishing to allow plants to establish after transplant. Plant the rooting cutting relatively deep to provide good support and balance in the pot for the maturing plants. Scout and treat for a range of insects and diseases, including Spider mites, Thrips, and Powdery mildew.
