Caring for your Bloom Theory

Keep Bloom Theory in a clean vase with plenty of fresh water, as Hydrangea is unusually thirsty and draws moisture not only through its stem but across its petals. If the Hydrangea heads ever look limp, mist them or briefly submerge the flower head in cool water to revive them rather than discarding the bloom. Recut the woody Allium stems at an angle every couple of days so they keep drinking freely, and strip any foliage that would otherwise sit below the waterline. Set the arrangement away from direct sun, heat, and ripening fruit, and both the airy Allium and the full Hydrangea will hold their shape far longer.

A note on your specific blooms

  • Allium — Change the water often and keep it fresh, as Allium stems can release a faint onion odour into the vase.
  • Hydrangea — Hydrangea takes up water through its petals — mist the heads and keep the vase topped up.

How long your flowers last

With Allium and Hydrangea together, expect Bloom Theory to stay at its best for roughly 5–8 days. The Hydrangea is the more delicate of the pair and tends to soften first, usually fading after 4–7 days as it loses moisture. The Allium is the quiet endurer here, often holding its sculptural form for one to two weeks and carrying the arrangement past the point where the Hydrangea begins to tire. The single most useful habit is to top up the water daily and refresh it fully every two days, since Hydrangea in particular drinks heavily and a clean, full vase is what keeps both blooms looking the way Amicis intended.

The story behind these flowers

A closer look at the blooms gathered into this arrangement.

Allium

Origin

Central Asia, the Mediterranean and the temperate Northern Hemisphere

Cultivated since

Ornamental use spread through Europe from the 1800s

Fragrance

Faintly oniony, otherwise clean

Symbolises

Unity, patience & strength

A member of the onion family, the Allium opens into a perfect sphere of tiny star-shaped florets held high on a bare stem. That clean geometry brings rhythm and altitude to an arrangement, drawing the eye upward and lending structure to softer, rounder blooms around it.

Hydrangea

Origin

Japan & the Americas

Cultivated since

Reached European gardens in the 1700s

Fragrance

Very light, fresh and green

Symbolises

Heartfelt emotion & gratitude

Named from the Greek for 'water vessel', the hydrangea carries full, cloud-like heads that shift colour with the soil — from blush and cream to deep blue. Its generous volume gives Amicis bouquets their soft, romantic fullness.
