Double Diamond Agapanthus (Agapanthus 'Double Diamond')

An agapanthus for places you thought were too small for one. Double Diamond is a true dwarf with heads of fully double, pure white flowers held on short stems above compact strappy clumps - all the summer sparkle of the classic driveway plant, shrunk to pot and border-edge size.

🌱 Why Gardeners Love Double Diamond Agapanthus

✔ Double White Blooms - frilly, fully double flower heads that read as pure white lace.

✔ True Dwarf Size - compact clumps with flower stems around knee height.

✔ Sets Little Seed - the double blooms produce minimal seed, so it stays where it is planted.

✔ Evergreen Neatness - tidy strappy foliage looks good all year.

✔ Classic Agapanthus Toughness - drought hardy and coast tolerant once established.

🏡 How to Use Double Diamond Agapanthus in Your Garden

✅ Pots & Planters - elegant white summer flowers for patios and balconies.

✅ Border Edges - a neat, low ribbon along paths and garden beds.

✅ Mass Planting - blocks of white for a crisp, coastal-style look.

✅ White Gardens - a reliable summer performer in pale colour schemes.

Easy Planting & Care Guide

  • Position: Full sun to light shade in most Australian climates, including coastal gardens.
  • Spacing: Plant 30-40cm apart for a continuous dwarf border.
  • Best Planting Time: Autumn or spring.
  • Watering & Care: Water to establish, then only in long dry spells. Snip off spent heads and feed lightly in spring; divide clumps every few years if they get crowded.

❔ FAQs About Double Diamond Agapanthus

How is it different from ordinary agapanthus?
Two things: size and flower form. It stays genuinely dwarf, and its blooms are fully double - layered white petals rather than single trumpets - which also means it sets very little seed.

Is it good in pots?
One of the best agapanthus for containers. A single plant fills a medium pot; our packs of 6 and 10 suit edging runs and grouped planters.

When does it flower?
Through summer, with the main flush arriving in early to mid summer in most parts of Australia.
