Evolvulus Blue Daze are native to South America. These creeping plants have unusual blue flowers which make them stand out. Their leaves and stems are covered in tiny gray hairs that remind you of peach fuzz. Their blooms have a short lifespan, but the plant continually produces more, which makes this a great hanging basket or landscape plant. Evolvulus will tolerate full sun, are easy to grow, and are hardy in zones 8-11.
For best results with Evolvulus, use a constant feed program of 200 ppm N
. Maintaining a pH between 5.5 and 6.5
is important to prevent iron deficiency. Allow the soil to completely dry between waterings. They do not like to be in constantly wet soil.
Evolvulus will bloom naturally in the spring as the days lengthen
. Each flower lasts about one day, opening in the morning and closing in the evening. The plant produces many blooms each day to keep the cycle going.
We recommend that you pinch
Evolvulus in order to maintain their shape and create a stocky plant. Allow 4-6 weeks after the last pinch for blooms to appear.
Space pots as needed for pot size. Normal 2' centered spacing is usually adequate.
HeightControlPlant growth regulators are not necessary
for Evolvulus. Allow the plant to grow, and shape the pots through proper pinching.
PestsWhiteflies, thrips, and aphids
are the biggest pest problems for Evolvulus.
Evolvulus are not prone to many diseases, but watch for botrytis
while the days are short. This grey rot is usually associated with wet or humid conditions. You can prevent botrytis by allowing the plant to dry out between waterings, allowing for good airflow in your greenhouse, and spacing to allow the sun to penetrate to the soil level. The most common chemicals used to treat botrytis are Medallion and Banrot. Use them as a drench according to each label's instructions.
Evolvulus require much less water in the winter. When the temperature is low, try to keep the ambient humidity low as well. This will guard against rot and fungus. However, do not let them get completely dehydrated because Evolvulus do not tend to recover well if they get too dry.
Planting Evolvulus Blue Daze Liners
- We recommend planting 5 starter plants per 10 inch basket. Use a well-drained soil in your baskets and plant your starter plants deep, allowing the ellepot to be completely covered by the soil. If you are planting 4" pots, 1 plant per pot should be sufficient. Plant it directly in the middle of your pot.
- Pinching is not required on a natural season bloom schedule, but it is useful in shaping the basket as needed. Remember to give yourself a minimum of 4 weeks from the last pinch for blooms to develop.
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.
