Blue Daze

Family: Convolvulaceae Flower

A wash of sky-blue blooms—delicate as spun glass—spangles Blue Daze from late season onward, turning the garden into a living watercolor.

The foliage forms a tidy, low mound of fine, silvery-green leaves, with a soft, airy texture that cushions the color and keeps the planting looking fresh. Ideal for edging, draping over borders, and filling sunny gaps, Blue Daze is a tough, perennial groundcover that rewards with long-lasting, vibrant color.

Culinary Notes

Chef's Note

Blue Daze reads more like a whisper than a flavor punch—use it like a delicate edible flower garnish, right at the end, so the petals stay airy and don’t collapse into the dish. Its sky-blue sweetness plays best with bright citrus and creamy bases where its light crunch can still be felt.

Best Uses

sparingly used as a garnish over chilled drinks and desserts
folded in at the last moment into buttered rice or warm grains for a brief floral lift
topped over yogurt, fresh fruit, or panna cotta to keep the petals intact

Flavor Profile

delicately floral mild, slightly sweet profile tender petals with a light crunch

Kitchen Pairings

lemon honey vanilla pistachio coconut white chocolate

Frequently Asked Questions

What pest or disease commonly affects Evolvulus glomeratus (blue daze), and how can I treat it?

Blue daze is most often hit by spider mites and occasional aphids, especially in hot, dry spells. Check the undersides of leaves weekly and spray affected foliage with a strong water jet, then follow with insecticidal soap if you still see active pests. Overly wet soil can also lead to root rot—let the top couple of inches of soil dry and ensure good drainage to prevent it.

How often should I water Evolvulus glomeratus during its main growing phase?

During active growth (after it’s established), water deeply only when the top 1–2 inches of soil feel dry to the touch. Aim for thorough soaking followed by drying rather than frequent light watering, since blue daze prefers evenly moist-to-drier conditions. In full sun, expect to water more in summer heat but still keep the soil from staying consistently soggy.

How do I know when Evolvulus glomeratus is ready to harvest?

Evolvulus glomeratus is typically grown for its flowers rather than harvested as a crop, but you can “harvest” by picking or deadheading spent blooms once plants start flowering around the ~90-day mark. Harvest/deadhead when flowers are open and at their most vibrant, and remove faded blooms regularly to encourage continuous flowering. If you’re collecting seed, wait until seed capsules dry on the plant and turn brown before harvesting.
